The T-Rex effect At Weiss GmbH in Buchen, an ultra-modern production cell was recently put into operation. It even drew a “boy, oh boy” from Sven Erfurt, responsible director for the project. But let’s start at the beginning.
04
The company Transfer systems, deltoid robots, handling units and functionally safe rotary indexing tables are the core competence of Weiss GmbH. This extensive product portfolio is offered worldwide. Today, 350 of the 500 employees work at the main location in Buchen. Comprehensive service, the uncompromising demand for quality and cooperation based on partnership result in great advantages for the customers. The situation Ongoing process improvement is one of the tasks in the Manufacturing Technology department. In this context, Mr. Erfurt and his team began thinking several years ago about the possibility of producing the many cast components, especially gearbox housings, in a single clamping operation. This, of course, was not only for the benefit of precision, but also for the efficiency on the production machines. Soon the discussion turned to the procurement of several CNC machining centers with automatic workpiece loading. Since the first, very positive, experiences had already been made with the zero point clamping systems from EROWA, the idea was relatively obvious to discuss the requirements for the new system with an EROWA process specialist.
Overview of the entire system. Blue are the CNC machines, green the pallet storage locations.
In search of solutions After initial clarifications on site, in which the suppliers of the POS Mill 800U processing machines were also involved, the first proposals were drawn up. The fact that only version V.14 of the layout plan depicts the final installed system clearly shows that such projects cannot be developed from one day to the next. A wide variety of requirements had to be met. ∙ On the one hand, the specifications for “only one clamping” had to be met. This was achieved by using the EROWA MTS Zero Point Clamping system and the ingeniously simple but highly effective fixtures on the pallets. ∙ Another requirement was the autonomy of the system. A complete third shift was to be produced unmanned. It quickly became clear that a corresponding number of pallets with prepared workpieces would have to be provided. ∙ In order to ensure the logistics of the components on the one hand and an optimum working environment for the system operators on the other, two independent setup stations were included in the specifications right from the start. ∙ For continuous production, the appropriate amount of tools had to be provided. Another requirement was to make this sub-task as clear as possible. ∙ Last but not least, the software that controls the entire cell had to be as easy to operate as it was complete in terms of monitoring and feedback of the processes. The cell – concept From all these specifications, it was clear that a solution with a rail-mounted robot would be the optimal choice. In this case, the necessary pallet storage spaces would be placed on one side and the processing machines on the opposite side of the linear track. Detailed clarifications also revealed that only the EROWA Robot Six had the necessary load-bearing capacity and the scope to reach into the machine. So, the choice was settled, and only the variant with the 6-axis robot was pursued. The proposal, detailed to meet the requirements, was well received and Weiss GmbH opted for the solution offered by EROWA.

The process control system Anyone still recall the DOS command: a:\\dir\ ? A lot has happened since the time when we had to tell the PC what to do for us. Today, we have reached the point where sophisticated programs suggest to us how to deal with the task at hand. The EROWA JMS 4.0 process control system is a program that is fully aimed at making production work easier. The assistance, such as process step sequence and graphical representation of the individual units, is a matter of course. At Weiss, the focus is on supporting the accompanying work steps. For example, the processes at the setup stations are displayed graphically on screens. The implementation EROWA’s expertise is to offer everything from individually automated machines to entire production lines and even the entire process control with integration in ERP and CAD systems from a single source.
As foreseen in the project schedule, we built the e ntire infrastructure, except for the CNC machines, in our assembly line. It included 15 meters of rail and 11 rack magazines, each with three places for a workpiece with maximum dimensions of 700 × 600 × 450 mm. We also incorporated the ER-Six, 6-axis robot with a load capacity of 500 kg and an operating envelope of over 2000 mm. The two loading stations for setting up the workpieces and the machine interface boxes rounded off the impressive size of the system. Now came the first real milestone in the whole affair: pre-acceptance testing by the customer at our facility in Büron, Switzerland. And here came the “T-Rex effect” mentioned at the beginning. When Mr. Erfurt came through the door into the assembly hall, he froze and then said bluntly: “Well, I’ll go out again and come back in. You really have to let this line sink in first!” The reaction is quite understandable; when faced with the big Robot Six on rails, comparisons
06
to a T-Rex automatically come to mind. (That’s also the internal pet name the robot has since acquired at Weiss). The 11 magazines lined up with the loading stations seemed to get lost in the depth of the hall. Off into reality After the successful pre-acceptance test, the entire system was dismantled, packed, loaded onto three flatbed trucks and transported to Buchen in the Odenwald region. The designated production hall was ready. In the correct order, the CNC machines were positioned, the linear track laid out and secured with strong anchors. All other components were also set up and the system was put into operation. Testing to the very bones In line with the scope of the project, an intensive test phase was started in order to eliminate remaining loose ends. In some cases, the theory of process organization had to be adapted to the practice of production engineer ing. But also on the practical workshop side, changes in the process became necessary. And not to be forgotten: The people in the workshop were highly challenged to adjust to the fully automated cell and to learn the new possibilities so that they could exploit the full potential. Today, the entire system runs in multi-shift operation and the intended components are produced with the required quality and reliability.
First experience When asked whether he would approach anything fundamentally different from today’s perspective after all the experience with the project, Mr. Erfurt replies, “No, not fundamentally. For us, this was the first automation project with multiple 5-axis CNC’s and all. Both the commissioning and the learning curve during the first productive period demanded a lot from all of us. Today, however, we have our T-Rex well under control.”
MTS
Safe is safe EROWA MTS 3.0 and 4.0: The first tooling systems to be certified to ISO 13849. Dual safety status monitoring meets all the requirements for modern machines in metalworking. New machining methods or strategies put the entire system to a test, where as workpiece holding devices face with specific challenges.
Open or closed? Prior to inserting or lifting out heavy pallets, or swiveling the entire machine table, it is very useful to know whether all clamping units are properly open or closed.
Monitored monitoring Both the MTS 3.0 (fully pneumatic) and the MTS 4.0 (electronic monitoring) benefit from the required dual safety. This means that signals are produced in such a way that defective components are detected immediately. If no release signal is generated an error message is output accordingly.
All chucking spigots present? Prior to starting a machining o peration, the system checks whether all the chucking spigots are present in the clamping units. The appropriate clamping power can only be achieved when they are. Appropriate clamping power? The various clamping units reach a closing force of up to 20,000 N. This is achieved with the “reclamp” function.

Hana ITM Co. Ltd, which was established in 2003 and based in South Korean Gimhae-si, is specialized in the production of parts for the aviation industry. To begin with, the focus was on honeycomb seals and shrouds for gas turbines, but then the company developed a new process for the production of lowpressure turbine nozzles. An interview with CEO Steve Yoon.
a grinding wheel is used in which a great deal of material can be removed without burr formation, this results in a big cutting depth. Also, the process is faster, and we get a good surface quality. The grinding wheel consists of diamonds and cubic boron nitride (CBN), which is the hardest known abrasive. We need this, because the workpieces themselves are highly resistant since they have to withstand extremely high temperatures.”
EROWA: Mr. Yoon, you played a key role in the development of the new process. Can you explain it to our readers in more detail? STEVE YOON: “It’s a 5-axis CBN creep-feed grinding process. The work-pieces are LPT guide vanes – LPT stands for low-pressure turbine. Our process machines the nozzle components that are needed for this part. In contrast to classical grinding, the process has the advantage that
It probably wasn’t all that easy to develop this process? “To tell you the truth, it was a big challenge for all of us. We developed, tested and re-adapted intensively for two years… and the entire solution required substantial investments. There are countless ways of machining turbine nozzles, and the methods vary from company to company. The machining technology of 5-axis CBN creep-feed grinding provided the break-through for the efficient grinding
of the radial grooves of turbine nozzles. We’re very proud of this, and we’re the only ones in Korea who are able to do this. It was also a very crucial step that the machine producer DOOSAN modified its DNM350 5ax with special grinding equipment for us, for this machine type is really a milling machine, but we use the machine for this creepfeed grinding process.” Not long ago, you and EROWA automated a production cell which consists of no fewer than ten such modified DOOSAN DNM350. They are served by the EROWA Robot Dynamic 150L. “The automation of the process was the next logical step. The whole plant is 25 meters in length. The robot serves five machines on each side. Added to this, there are two loading stations, and after the machining process, the parts are washed and checked on a coordinate measuring machine. This plant has proved extremely successful. We were able to reduce personnel expenditure by 75 percent while reducing non-conformities by 30 percent. And this with a simultaneous increase in production agility. I can say that we’ve attained our objective!”

How long have you been working with EROWA? “The cell I’ve just described constitutes the start of our cooperation with EROWA. The project started in early 2020. Incidentally, it’s not only the robots and loading stations that are from EROWA but also the universal UPC workpiece tooling system, which has been installed on all machine tables. And the JMS 4.0 process control system, which also makes a crucial contribution to success, operates in the background. It provides us with all the production data and provides a comprehensive overview of the workflow at all times. The washing machine and the measuring machine are also integrated in the process.”

Steve Yoon, CEO Hana ITM
What was the main reason for you to invest in this EROWA Solution? “Well, the entire system is very agile and flexible. But that’s clear, we’re talking about major orders when ten DNM350s are working at the same time. Also, our customers from the aero/gas turbine sector are international players: B/E Aerospace (is part of Rockwell Collins USA), Sukhoi Civil Aircraft of Russia, Hanwha Aerospace Korea with end customers GEAE and Pratt & Whitney, and many others. To be successful, you don’t only have to be competent but also competitive with regard to quality, technology and prices. In addition, you’ve got to have the necessary certifications; in our case, AS9100, the international standard for quality management systems of the aviation, space and defense industries. We’ve also have the NADCAP certification, a standard of the aviation industry for special processes and special products; this is about the highest degree of process control.”
What are Hana ITM’s plans for the future? “We intend to carry automation further, yes. This can be an option in a wide variety of areas, in grinding, milling, EDM… At present, we have very specific hopes of being awarded a new project – and that could very well be the next order for EROWA.” Mr. Yoon, thank you for this interview!
HANA ITM INC. The headquarter of the company is located in Gimhae-si on the southeastern coast near Busan, the country’s second largest city.

HPC
Highly productive Once it is installed and aligned on the machine, the EROWA Heavy PowerChuck shows its true potential. The machine time is exclusively used for production, as you no longer need to worry about the positioning of workpieces on the table.
Modular design Clamping modules are positioned exactly where the machine’s table size and the pallet’s optimal size require it.
External setup and presetting While a workpiece is being machined on the machine, the next order is already being prepared outside the system. This dramatically increases the machine’s productivity, since the effective change time becomes very short.
Clean pre-centering The pallet or the entire table is positioned above the HPC system via the pre-centering. When handling with a crane or forklift, the entry or exit from the individual clamping modules is under control.
Endless power Positioned, centered, clamped – with a clamping power of 40,000 N per module, pallets containing workpieces will withstand any stress without budging during milling.

Everything
under control! 12
The CEO of Northern Italy’s titanium specialist Poggipolini is convinced that with EROWA as a partner, the family business is ready for the challenges of the future – after a decisive step into automation with an EROWA Robot Dynamic.
Focus on titanium Poggipolini S.p.A. was established in 1950, and its headquarters are still in San Lazzaro di Savena, a municipality that is part of Bologna. A number of additional production facilities are also situated in this municipality. The focus is on titanium machining; in particular, components for the automotive, aviation and aerospace industries are produced. “We’re top specialists for the design and production of critical fasteners and structural components made of titanium and special steel alloys,” explains Michele Poggipolini, who runs the company in the third generation. “Additionally, we’re specialized in the galvanic process for the anodization of titanium and the passivation of steel, and we’re certified in accordance with aviation standards,” he explains. And Cristian Bernardi, Head of Industrial Engineering, adds with pride: “The entire production process takes place in-house:
from raw material procurement to hot forging, precision machining, cold and hot thread rolling up to the final heat treatment and quality checks. What matters This aspect of keeping everything in-house and thus under control is very important for the company’s quality philosophy, adds Michele Poggipolini, for only in this way can the firm satisfy its own requirements. “Thanks to a team of highly qualified technicians and engineers and the use of specific software, we’re able to support our customers from the design stage to implementation,” he says – and all this in a highly competitive environment,
“With the new line, we’re able to suitably automate the production process even with small series.” Michele Poggipolini, CEO of Poggipolini S.p.A
as Cristian Bernardi explains. “Thanks to its lightness combined with very great strength, titanium can be used to produce parts for Formula 1 racing cars, luxury cars, aircraft, helicopters, drones and space flight.” Typical production batches range from three to one hundred parts, he says, “but thanks to the use of automated cells, we’re now also ready for mass production.” And this is where EROWA comes in. Investment in the future For some time now, a Robot Dynamic ERD250 XTL has been performing its services. Thanks to its long X-axis range and load-bearing capacity of up to 250 kg, it serves the three Makino DA300 five-axis machining centers with ease. The new production cell is equipped with three rotatable workpiece magazines, which offer a great deal of capacity for the EROWA UPC 320 × 320 mm workpiece carrier pallets that are in operation. The loading station, which has been additionally integrated, serves to provide the cell with the set-up and palletized workpieces or fixtures. “Although we’ve been working with EROWA products for about 20 years,” says Michele Poggipolini, “this step is still of enormous importance.
Automation is the key to success because it’s the sole possibility for keeping the production processes under control and increasing the efficiency of the machines. The line we’ve now configured was chosen because it enables us to maintain the flexibility that is our hallmark. and we are able to suitably automate the production process even with small series. At the same time, the expandable system enables us to grow step by step while keeping the process 100% under control.” Keyword control Of course EROWA’s process control system also plays an important part in this. As is well known, the EROWA JMS 4.0 interlinks all the data and controls the entire production process. “It’s a growing system with which we constantly discover new options,” says production manager Cristian Bernardi. In any case, the company is well on its way towards the smart factory: “Thanks to a specialized software, we can run the production process virtually at first,” explains the CEO himself. “All the processes are interlinked and connected up to the management system. We’re also working on a digital twin model of our entire enterprise with which we’re able to manage and simulate all our production processes! With the new robot from EROWA, we’ve made a step in the direction of automated production with a very high degree of process control,” concludes Michele Poggipolini. “We’re well on track.”

EROWA in Årjäng Customers of HANZA Mechanics Årjäng can be found in a wide variety of industries, but most come from the energy sector. The company machines workpieces whose sizes range from 20 × 20 × 20 mm to 300 × 300 × 300 mm, typically in batch sizes of up to 100 parts with demanding geometries, strict quality requirements and machining tolerances in the range of only a few thousands of a millimeter. And it is precisely for this reason that automation is particularly valuable here. “In 2004, we made the trailblazing decision to use EROWA’s UPC 320 × 320 mm workpiece tooling system on all the machines,” says Ola Svensson, Site Manager at HANZA Sweden. From 2006 onwards, we started to automate our EDM centers with EROWA robots.” Various models are in use, according to requirements. “Our latest investment is an EROWA Robot Dynamic 150L. It serves two SODICK AG60L EDM centers and a MITUTOYO coordinate measuring machine,” Ola Svensson explains further. Thanks to the previously introduced tooling system, the workpiece carriers are changed from machine to machine with precision. The new production cell has a magazine capacity for 300 ITS electrode holders and 50 UPC 320 × 320 mm pallets. A considerable amount of time saved To minimize the risk of errors in manual electrode changes, the measuring machine was also integrated into the

15 process after installation. Ola Svensson is very satisfied: “This cell does not only serve the introduction of new technologies since our EDM centers are reaching a certain age,” he explains. “Our aim is that the new production cell works around the clock with the highest degree of reliability with one shift of operators.” “The integrated EROWA process control system also provides valuable support and makes it easier for our operators to process orders and keep an overview of the cell; and not least, the time needed to program parts was consider-
ably shortened. It is also very gratifying that the datum points can already be planned at the design stage. Accordingly, an extension with an additional SODICK machine is in the pipeline. In this respect, we at least benefit from the fact that SODICK and EROWA have been cooperating for many years.” If the success of this cell is further confirmed, HANZA intends to continue with automation: “A similar step is being planned in the milling department, where we want to upgrade the existing cell with a milling machine for electrodes, a washing station and an additional EDM center.”

Well sprung
into the future At Spühl, everything pivots around springs. Literally. And has done so for more than 130 years. At that time, the first patents for coiling machines for the production of all kinds of furnishing and mattress springs were submitted. Since 2014, the company has manufactured such facilities according to the insights of “Lean Manufacturing”. Just-in-time is not merely a buzzword, but a program. Production in Switzerland requires the highest degree of efficiency. An important component of this is EROWA’s FMC manufacturing technology.
The company primarily serves its parent group, Legget & Platt, which runs operations all over the world. A smaller part of the machines it produces are sold on the free market. Under the brand of Spühl Production Services, services for general machine-building are provided in the German-speaking area. On the one hand, this ensures that the capacity of the production units is put to optimal use; on the other hand, the company’s presence in the free market enables it to retain its fitness with regard to delivery speed and cost optimization. Top equipment “If you want to be and remain competitive today, modern facilities and the constant improvement of the planning and production processes are indispensable,” says
P roduction Manager Patrick Jung, and illustrates this with an impressive guided tour of the production halls. “The standardization of components and processes provides us with planning security. In this way, we lay the foundation of quality, adherence to delivery dates and c ompetitiveness. It’s an impressive feature of our production that it covers a wide range of dimensions and manufacturing processes. This enables us to optimally process orders involving different requirements on our own premises. To survive in a “high-price island” like Switzerland, the facilities must be automated in a way that enables us to change from one order to another flexibly and with the least amount of work, regardless of the batch size. With the new facilities by HELLER and EROWA, we’re able to do so at an extremely competitive level. But what’s equally important are:”
REPORT www.spuhl.com
Top employees When asked about the support given to the entire Spühl team, Patrick Jung explains: “We regard our employees as our most important asset. Regular investment in basic and advanced training contributes to their personal development. This, in turn, results in satisfied and motivated people. Currently, we employ 200 people. We’re also looking after the next generation: our 31 trainees are the foundation for our future success.”
investment was absolutely open since Spühl was pursuing a new manufacturing strategy. “Our experience of an EROWA robot combined with a HELLER 5-axis production cell was very positive. By then, EROWA had taken over SCHULER’s “LoadMaster” product line. So we ordered the latest HELLER FP14000 with the LoadMaster Compact Extended by EROWA,” says Patrick Jung.
Digital twins The big challenge in the manufacture of one-off parts is automation with the smallest amount of effort. Spühl succeeds in this by means of a completely digital simulation of the production process. Some of the conditions required by this simulation are created with the use of the EROWA tooling system. Fixtures for the accommodation of workpiece blanks are mounted on precise pallet systems. Thus their position on setting-up stations and in machines can be repeated at any time. A further condition is satisfied through the unconditional standardization of data models, machines, tools, fixtures and components. Known values in all these fields create a situation whereby the simulations for the production process can ultimately be so close to reality that one-off parts can be produced with a minimal trial run. This saves presetting and setting-up time!
LoadMaster Compact Extended In constant pursuit of improvement, Spühl regularly subjects its existing machines to critical assessments and replaces them if necessary. In this case, this concerned a plano milling machine with a travel range of six meters (one of the few machines without any automation). Since the main point is not buying a great machine but machining the most frequently occurring workpieces, Spühl first analyzed all the components with regard to size and machining requirements. As the company was used to dealing with large volumes, the widest interference circle of palletized workpieces was set at 3 meters. Thus the dimensional area would contain 80% of the parts to be expected, which meant that the value creation of a great proportion of products would remain in-house and contribute to economic success.
Automation has tradition The signs of the times were recognized by Spühl a long time ago. Back then, the company purchased HELLER machining centers with integrated automation. When the new generation of machines without automatic loading/ unloading facility came onto the market, Spühl opted for the SCHULER linear storage system. The first facility with two-level linear storage was procured in 1998. By 2014, this had evolved into nine loading facilities of different types. The impressive thing throughout their operation was the high quality of the facilities and the simultaneous trouble-free availability. In 2019, Spühl acquired the first facility (HELLER HF 3500) with an EROWA Robot Dynamic 150 L. The selection process for this
19
20 The procurement of the new 5-axis machining center with an automatic loading/unloading facility that was evaluated in this way replaces two older machines. However, this is only successful if the autonomy and thus the efficiency of the cell can also be realized. High standards to be satisfied The new production cell has to face quite a few c hallenges. Components 2.9 meters in size have to be palletized, the storage system must be able to accommodate at least 10 pallets and should be able to be extended for further places. It must be possible for the workpieces, which weigh up to 3 tons, to be prepared on a walk-on presetting station. The 5-axis machining center must be linked up with the existing ERP with a process control system that provides a clear overview.
Flexible answers “Owing to the modular design of the automation unit, adaptations to our requirements with regard to the interference circle are very simple. Also, EROWA’s process control system enables us to keep an overview of the complex order processing system. The operation of this control system is intuitive. You can see at once that the developers at EROWA let themselves be guided by practice. Thanks to the link-up with our ERP system, the operator knows at all times how far the orders have progressed and which ones are next in line for processing.” The result Setting up such a big plant takes some time. In the case of this specific facility at Spühl, it took about two months. The installation proceeded well, however, the individual
components are standardized and have to be connected with each other according to the “plug-and-play” concept, Cooperation between HELLER and EROWA went without a hitch. “The machine operators got the hang of things very well from the very first day,” says Patrick Jung. Their experience of the EROWA automation and the JMS 4.0 process control systems could be applied 1:1 to the new facility. According to HELLER’s motto “If you want to complete as many tasks as possible with one single machine and want your production to be safe not only now but also in the future, then the purchase of a HELLER 5-axis machining center of the F series is the right decision” and with the good experience gained with EROWA’s

automation, Spühl cannot fault anything connected with the cell to this day. The operators are highly satisfied with the ergonomics and the easily manageable software. The production management is pleased that it is able to rely on plannable production hours. Or, to return to the title of this story: “Well sprung into the future!”

Slimming cure The transfer axes, gripper, and linear rail of the ERD 500 are all equally impressive. They reliably and swiftly transport workpiece pallets weighing 500 kg in total. The new telescopic axis and the extremely low rail for the linear movement allow for considerable amounts of space to be saved. All that with the same or even improved stability. Range The total range of the X-axis measured from the center is two meters and forty-two centimeters (2,420 mm). The effective gripper movement of 1,593 mm reaches well over 100 mm further than the previous model, and that is sometimes decisive.
Fast but safe When transporting a weight of 500 kg, safety is of the essence. Torque limitation, speed, and delay values are all controlled accordingly. Savings passed on We have found ways to reduce acquisition and manufacturing costs in various nooks and crannies. We are happy to pass on these savings in our sales price.

New perspectives – new processes The cooperation between the Portuguese company Aurimoldes and EROWA is still comparatively young. But it has immediately led to a change in thinking on the part of the customer – and therefore also to an optimistic view of the future.
“T
he beginning of cooperation with EROWA led to a paradigm change in our company,” says Paulo Tavares, the CEO of Aurimoldes, “since the new automation solution enabled us to change our working concept with regard to the set-up of our milling machines; now, an almost complete utilization of machine time without operators is possible, and this has resulted in a new, autonomous working regime in the company.” An important partner The decisive step for this radical change was the acquisition of an EROWA Robot Dynamic 500 intended to serve a total of four CNC production machines. In this decision, a long-standing partner of the company played an important role: “Our investement was motivated by the necessity of putting our production time to better use,” explains Paulo Tavares. “In addition, and with all the changes we’re experiencing in our sector, the relationships and partnerships we’ve got with our suppliers sometimes help us to see more clearly and further ahead. In the case of the EROWA robot cells, we relied on a supplier which is a partner for life: Graphite Technologies, which has been the representative of EROWA products in Portugal for 20 years. With their well-founded knowledge of the mold market, Graphite Technologies was the bridge to the success of our investment, since I’m able to rely on the recommendations made by Hilario Costa, who has been cooperating with us on all EROWA projects,” says Paulo Tavares. The future begins under corona But when it came to realizing the project, the Covid pandemic was peaking – and Aurimoldes recorded the biggest decline in orders in its history. “I can’t say it was easy to continue with the installation of our new EROWA robot during that time,” says Paulo Tavares. “But we saw that as an opportunity for better learning and training. We restructured the shop floor, reorganized our work teams, trained the employees and rethought the way we planned our projects. We did all this because we had more time than would have been the case at a normal production rate.”
Hilario Costa, Graphite Technologies and Paulo Tavares, Aurimoldes
23 Complex molds The main products of Aurimoldes are molds for parts in high- and low-pressure die casting, as well as molds for plastic injection and zamak, a harder and more resistant zinc alloy. One specialty is magnesium thix-omolding, with which thin, light and highly stable parts can be produced from magnesium alloys at a favorable price. The company’s target market is the automotive industry in particular, but they also service other sectors including hydraulics, electrical, packaging and glass. “We produce many molds for parts in the automotive sector, for example rearview mirrors, roof racks or chassis. We’re involved both in com pletely finished projects in which our molds work in robot-supported and fully automated cells, and in development projects, in which we have to produce prototypes.”
24
Supporting employee development The company is based in Gafanha da Encarnação. The town, which is situated approx. 60 kilometers south of Porto, is part of Aveiro, one of Portugal’s most important industrial locations. Aurimoldes was established there in 1997 and has grown rapidly. Today, the firm employs just under 40 employees, whose age structure combines a high degree of experience with the dynamism of youth in an ideal way. Aurimoldes employees benefit from a philosophy which focuses on the improvement of working conditions and the training of team members. “We’d like to promote and improve our employees’ skills by encouraging continuous training and providing appropriate opportunities,” says Paulo Tavares. “This also includes all employees’ active participation in and responsibility for the quality management system and for corporate growth. The aim is to reinforce and consolidate an integrated and coherent vision of the organization.”
“We’ve already started to save time.” Paulo Tavares, Manager AURIMOLDES
Increasingly international orientation Versatility, adaptability and precision are the key elements in the development of the Aurimoldes’ projects, explains Paulo Tavares, and continues: “The ability to find quick and innovative answers makes for a higher degree of efficiency and competitiveness with regard to prices and delivery times, and this has led us to the top of mold making.” To begin with, the company had the national market in its sights but soon turned towards international contexts. “Currently, our commercial strategy is p ursuing an increasingly globalized market vision,” says Paulo Tavares.
25
“In the last ten years, we’ve evolved into a mainly exporting enterprise.” But the international markets are fiercely contested. “There’s a lot of work which is d rifting from Europe to points further east and accordingly, our market has to cope with very low prices. It's very demanding to keep pace with it all, particularly if you want to maintain the quality of the processes and services without any compromises. Therefore automation appears to be absolutely indispensable.” Automation is being pushed ahead In 2018, Aurimoldes took an initial step by commissioning an EROWA Robot Easy. Since summer 2020, an EROWA Robot Dynamic 500 has now also been in operation, serving three Quaser machining centers and a Feeler vertical lathe. The objective of this significant purchase was a better utilization of production times. “But our new and automated production cell has also prompted us to imple-
ment new methods for the support of work preparation. Among other things, the programming process was modified to enable the EROWA process control system to control the NC programs.” Tavares is extremely satisfied, even under corona conditions. He puts the decisive factor in a nutshell: “We’ve already started to save time.” And he then sums up: “Our thinking has changed, and we therefore believe that there’ll be further projects with EROWA in the future.”

Exactly
what we were sold The small town of Plover is located in the middle of Wisconsin, a state in the north of the USA. Here, the company Pointe Precision, Inc. manufactures high-precision components. For some time now, this has also been done unattended, as Joe M. Kinsella, Executive Vice President, tells us.
26 EROWA: Mr. Kinsella, what are the main activities of your company? JOE M. KINSELLA: “We offer top-quality manufacturing solutions. These can be medical devices or fuel control systems for aircraft engines. These are typical examples of components that must be precise and meet the highest quality requirements because human lives are at stake in their application. The fact that we manufacture many vital components and parts here at Pointe Precision is a source of pride for our employees.“ What types of machining do you offer? “Pointe Precision provides full-service precision CNC machining solutions for leading manufacturing companies across the country. We specialize in precision milling, turning, grinding, heat treating and CMM inspection by name. We are certified to AS9100, ISO 9001 and NADCAP and
hold a federal firearms license. Our services support our customers throughout the entire manufacturing process. Pointe Precision has an outstanding staff that is open to new technologies and eager to learn.“ New technologies, that probably also refers to automation with EROWA? “Right. For some time now, an EROWA Robot Dynamic 250L has been operating five Hermle C42 turning and milling centers here. These, in turn, are equipped with the MTS400 and PC210 clamping systems. Automation is very important to us because it allows us to keep machines running and produce high-value, complex parts for aerospace, for example, without employees having to work undesirable shifts or weekends. Automation compensates for rising labor costs, not to mention the difficulty of finding qualified workers.“ So you are satisfied with the EROWA Robot Dynamic? “Absolutely, yes! It is exactly what we were sold: a reliable, extremely accurate system that guarantees high repeatability and allows us to machine critical parts with tight tolerances unattended. What surprised me in a particularly positive way: The robot has required very little maintenance since the initial installation!“ You also work with the EROWA process control system. What is your experience there? “We use it to monitor, schedule and track all production orders across the five machining centers, the robot and every single fixture in the magazines. We track machine alarms, production hours, and all of our individual pallet zero offsets so we can run the same job setups in different machines.“

“EROWA's Robot Dynamic a llows us to machine critical parts with tight tolerances unattended.“ Joe M. Kinsella, Executive Vice President of Pointe Precision
How do you organize orders? “We have a general first operation, which mainly allows the definition of the zero points. Then the critical features are loaded into the system so that the strict quality and inspection requirements can be met. The final o peration then incorporates numerous in-process inspections, including offline CMM inspections.“ Mr. Kinsella, thank you for this interview!
POINTE PRECISION, INC. In 1995, in the wake of the closure of a large manufacturing facility in Stevens Point, Wisconsin, Joe Kinsella Senior recognized the opportunity to start something new and to be able to count on experienced employees. The newly created Pointe Precision started with 94 employees. Initially, the focus was on the manufacture of high-precision components for the aerospace and industrial markets, but later customers from the medical and leisure industries were added. Today, the company headquarters are located in neighboring Plover; the production area covers almost 85,000 square feet. Setup and installation of the EROWA Robot Dynamic.

Titanium,
robots and pyramids 30
The highest degree of precision within the scope of the possible, perfectionism and uncompromising quality – these are the standards that K&M Präzisions technik has set for itself. The firm is part of the Müller Group, which was established in 1991 and now consists of four autonomous companies with just over 100 highly qualified employees. Within the group, K&M Präzisionstechnik specializes in the production of demanding turning and milling parts and considers of itself as a reliable, competent and innovative contract manufacturer. Markus Müller runs the family business in the second generation. Precision and quality Demanding one-off parts, small and large series are produced individually according to customer requirements. Typical materials are plastic and metal, for instance aluminum, brass, high-grade steel and titanium. Customers operate in medical technology, aerospace technology, machine- building, as well as in the electrical and sensor industries. Specific examples for medical technology include vertebral implants, as well as bone screws, nails and implants made of titanium.
Titanium and high-grade steel “The production of demanding parts made of materials that are difficult to cut, such as titanium and high-grade steel, may be regarded as the specialty of the house,” says Ludwig Jehle, who runs a production department at K&M. When it comes to chip-cutting, a great challenge is presented by titanium, which always requires a precise, experience-based selection of tools. Also, a special cooling lubricant has to be used because of the high process temperatures. “Particularly when it comes to a high degree of precision with complex geometries, titanium becomes really demanding. But it’s worthwhile!” The main operative areas are components of jet engines for the aviation industry, chassis for the automotive industry and implants for medical technology. “The main motivation for the use of titanium is its low weight,” explains Ludwig Jehle. “It merely amounts to about 60% of the specific weight of steel and can therefore be used wherever a reduction in weight combined with a high degree of strength is required.” Automation with EROWA K&M Präzisionstechnik took the first steps in the direction of automation relatively early. Cooperation with EROWA goes back to 2005. “However, we’ve intensified efforts in this direction in the last few years, in particular,” continues Ludwig Jehle. “In 2014 and 2017, we acquired an EROWA Robot Leonardo, and since 2017, we’ve been working with EROWA’s JMS 4.0 ProductionLine process control system.” The primary objective of automation is to increase machine running times and to reduce throughput times through a reduction of resetting processes: “To remain competitive, we endeavor to constantly optimize our production processes – and this means equipping the company with progressive technologies and machines,” says Ludwig Jehle.
31
Automation should enable K&M to keep the production process going around the clock – 24 / 7. “In particular, we want to produce prototypes and small series during normal working hours while running the bigger series at night and during weekends.” Leonardo and GROB At K&M, an almost classic interpretation of this task is taken on by the two GROB G350 five-axis universal machining centers, each of which was equipped with an EROWA Robot Leonardo pallet loader. Together with “RINK Werkzeugmaschinen”, it was defined how the machines could be used as efficiently as possible in daily operation. “We’ve cultivated a partnership with HansHerman Rink for many years,” explains Thomas Lüscher, Key Account Manager at EROWA, whom the project was entrusted to. They opted for the EROWA Robot Leonardo model with a magazine capacity of 32 EROWA UPC 320 × 320 mm workpiece carrier pallets. Thomas Lüscher comments: “For the GROB machines to be loaded, the Leonardo pallet loader in combination with the EROWA UPC workpiece palletizing system is an extremely productive and optimally attuned automation solution.” The robot is equipped with multilevel magazines and manages transfer weights of up to 120 kg, thus covering a very broad range of parts. There is also the possibility of working with two different pallet types thanks to an automatic gripper change. The robot is linked up with the Heidenhain control unit of the GROB machine through an integrated interface. In this way, it is very easy to program.
The pyramid This combination was provided with an additional dimension by means of an innovative fixture, the “clamping pyramids” used at K&M, which are a customer-specific product made by EROWA. “We developed the idea and the design for this together with Hans H. Rink,” says Ludwig Jehle. David Estermann, who is in charge of individual clamping solutions at EROWA, adds: “The pyramids are made of aluminum and attached to EROWA UPC pallets. Four self-centering vises are fitted to the pyramids. The fixture which is equipped with self-centering vises at an angle of 45 degrees allows for excellent accessibility in five-axis machining. “EROWA completely manufactured the clamping pyramids and delivered them ready for use two months after the order.” “The advantages are remarkable,” says Ludwig Jehle: “In contrast to before, 2–3 workpieces more are set up for machining. The use of the 4-fold clamping pyramids entails fewer robot exchange processes, the machine operates longer unmanned, and throughput times are substantially reduced at the same time. Also, additional machine capacity is available to us for further orders. We’re really very satisfied with this solution.”

Higher investment returns, better order planning Established in Imola in 1919, today running 80 production, distribution and service companies with approx. 4,600 employees in 27 countries – these are the impressive benchmark figures of the SACMI Group. The parent company, SACMI Imola, is home to the R&D activities and, in particular, the mold-making department for the Rigid Packaging Technologies division. Here, process automation and control are part of the philosophy.
Luca Bergano, EROWA and Marco Fattorini, SACMI
32 Many-faceted product world The more than a century old history of SACMI is peppered with successes. For one thing, the company based in the famous North Italian tile region, is a leader in the design, production and development of machines and complete systems for the ceramics industry, which besides tiles also covers sanitary installations and cutlery. However, the crown caps which close millions of beverage bottles worldwide are made by machines from the house of SACMI. The product was invented in the 1950s and resulted in the company’s global monopoly position. Since the 2000s, solutions to the development of capsules, containers and preforms have been added to this. The core activities of the machine and mold development of Rigid Packaging Technologies take place at the same location in Imola, the heart of research and development of the entire SACMI Group. Technology for rigid packaging Marco Fattorini, Head of Production, is the master of the 4000 square meter mould making department for the Rigid Packaging Technologies business unit. “We employ around 90 people here and the same number of machine tools,” he explains. “We spend a total of 250,000 hours a year on high-precision machining processes in the
micron range.” The company supplies multinational beverage producers and produces machines for the manufacture of capsules, preforms, containers, and also entire assembly systems and fixtures for cutting and folding safety seal tapes. “Our mould making department carries out all the machining here,” explains Marco Fattorini. “It ranges from internal and external grinding to hard turning and from high-speed milling to die-sinking and wire erosion. Additional capabilities include manual polishing, deburring and vacuum heat treatment all while maintaining quality measurement and control. With some of these processes, EROWA has become an important partner by now.” The philosophy of total automation “Our company recognized the present signals of the market early on and knew how to react to them accordingly,” explains Marco Fattorini. “They point in the direction of digitalization and total automation. We’ve made this approach into an integral part of SACMI’s entire operation, from design to sale and beyond.” Thus EROWA’s manufacturing philosophy and products are an excellent match for SACMI’s strategy, which aims to improve the quality of products and the diversity of the machines. “Our production islands run almost 24/7, and thanks to automation and control, unmanned operations are continually being extended,” says Fattorini. These automated processes are part of a superordinate smart factory idea: “The smart factory is already reality at SACMI, in a market that is constantly evolving.
“The system is outstanding on account of its scalability and modularity.” Marco Fattorini, Head of Production

GFAC laser machine. Finally, in 2019, the linear solution EROWA Robot Dynamic 150L was installed, which supplies three Mitsubishi EA8 EDM centers. Marco Fattorini is convinced that “this was a decisive step, for besides the superior quality and versatility of the solution, which enables us to reduce guaranteed tolerances even further, the system is outstanding on account of its scalability and modularity.” The linear Robot Dynamic platform is characterized by the possibility of integrating additional machining centers into the existing production cell. “And that’s precisely what we’ve already planned. A fourth EDM center will soon be integrated!”
Intelligent and interlinked processes also mean for us that new products can be developed in next to no time while additionally guaranteeing customers the best quality. One example of this are the so-called tethered caps. According to an EU precept, these sealing caps must, in the future, also remain firmly attached to the beverage bottle after opening to prevent them from getting into the environment. We supply what it takes to make it easier for our customers to cope with the technological switch-over.” Enter EROWA EROWA’s technology was introduced into the company in 2000, initially with mechanical fixtures. In 2017, they were followed by an EROWA Robot Compact 80 on a
Furthermore, an EROWA Robot Compact 80 was inte grated into the department in 2020, which was combined with a Röders high-speed milling center. Here, too, the magazine capacity and thus the performance of the cell is intended to be extended in the medium term. “The EROWA technology has made a crucial c ontribution to SACMI’s strategy of increasing product quality and the versatility of the machines in that it has enabled us to conceptualize production islands that run around the clock even when no operator is present,” emphasizes the head of department. The mainstay: JMS 4.0 Every part that leaves the mold-making department of SACMI Imola has be identified with a numerical code and a QR code which provides essential information
about its production (production plant, order number, change status, part number, etc.). From the perspective of quality, EROWA is a valuable partner with its JMS 4.0 process control system. The system is used both for EDM and in the milling island. “An increase in investment yields and an improvement in order planning by its integration into the company’s ERP system are among the main advantages,” explains Marco Fattorini. “The JMS 4.0 panel provides operators with all the relevant process parameters. The software enables us to plan the various processes efficiently and optimize them at all stages. In addition, the system supplies valuable information about the operating life of the materials used, from tools to electrodes. This is a fundamental aspect when you work with tolerances in the micron range, in which critical problems and deviations in the processes have to be identified in advance. The result is that the department has had a fault rate of less than 1% for years and has constantly been able to increase its performance parameters.” Efficiently into the future Marco Fattorini is satisfied: “SACMI has attained its current goals. Efficiency throughout the production process has been greatly improved. In this context,
we also speak of OEE (Overall Equipment Effectiveness). This measurable factor consists of the performance parameters of our plants with regard to versatility, availability and the simultaneous reduction of error sources. This information is also displayed on the dashboard of EROWA’s JMS 4.0 control system. These results fit precisely with the “spirit” of smart production. Of course this is a process that is still ongoing and which the company will c ontinually engage with in the years to come.”
