Abstract - Generally, the growth of Indian manufacturing sector is largely depends on productivity & quality. Productivity depends upon various factors, one of the major factors is efficiency with which the operation activities are carried out in the industry. Productivity can be highly improved by reducing the machining time and combining the operations etc. As the name indicates twin spindle drilling machines have two spindles driven by a single power head, and these two spindles holding the drill bits are fed into the work piece simultaneously. The centre distance between two spindles can be easily adjusted. For this purpose, the drill spindles are connected to the main drive by means of universal joints. We can drill two holes at a time with provision of varying centre distance between two drilling spindle. It has advantage of portability. The size of machine is smaller than the older machine so it is very simple to move from one place to another. So this machine can be easily transported. The overall space required is also minimizing. The efficiency of this machine is better than the older machine. Large saving in power has been achieved. The machine is very simple to operate. It drills the holes at faster rate. Keywords- Spindle, drill, Sun gear, Planet gear, Drill chuck Etc. 1. INTRODUCTION In today’s market the customer demands the product of right quality, right quantity, right cost, & at right time. Therefore it is necessary to improve productivity as well as quality. It can be achieved by using multi spindle drilling head. On the other hand, it is possible to meet quality requirements of final product . For mass production, Multiple-spindle drilling machines are used. It is a time saving technique. Multispindle head machines are used in mechanical industry. Therefore it is possible to increase the productivity of machining systems. It is used to drill two holes in a work piece simultaneously, in one setting. The holes are drilled on number of work pieces simultaneously. It is easy to make them interchangeable. Two spindles of machine is driven by a single motor simultaneously. © 2017, IRJET

In this system, motions are obtained either by raising the work table or it can be done by lowering the drills head. The centre distance between the drill spindles are adjusted in such a way that spindle are connected to the main spindle by universal joints. In mass production work drill jigs are generally used for guiding the drills in the work piece. It is necessary to achieve the accurate results. Drilling depth can not be estimated properly. Different size of hole can not be drilled without changing the drill bit. It consumes lot of time for doing repeated multiple jobs. These all are the drawbacks. It is necessary to find out solution of the problem. To overcome all these problems, this automated drilling machine is designed. The main aim of this machine is to drill the hole. 2. LITERETURE REVIEW In the present chapter the contribution made by different researchers and authors in the field of manufacturing were enlist in short. It includes the methods, mathematical modeling, different input parameters well as their output result. The literature is based on gear box of multi spindle drilling head; finally the summery of literature reviewed was added. Prof. Shingavi et.al. stated that the challenge of modern machining industries is mainly focused on the achievement of high quality, in terms of high production, less wear of cutting tools, economy of machining by considering cost saving and increase the performance of the product. With stiff competition and challenges in the present-day market, manufacturers are compelled to be more responsive to the customer’s demands regarding right quality, right quantity, right cost, & at right time. Productivity can be improved by reducing the total machining time, combining the operations Productivity and performance of the existing drilling machine will be increased by Design & Fabrication of Multiple Spindle Drilling Head. [1] Prof.Shinde et.al. explain about the growth of manufacturing sector depends largely on its productivity & quality. All manufacturing activities are carried out in organization. Generally, Productivity depends upon many factors. But it is mostly depend on manufacturing efficiency. ISO 9001:2008 Certified Journal
