VT 100 GT – VERTICAL TURNING & GRINDING IN ONE MACHINE
VT 100 GT
The Versatile Solution for Productive Shaft Manufacturing The VT 100 GT offers quick processes for hard turning and grinding. The tool turret completes all turning operations followed by grinding at a second station. Gearbox shafts, rotor shafts, pump shafts, engine shafts, propeller shafts and balancing shafts differ greatly. For example, the strength of the component plays a decisive role. While strong workpieces with a defined blade can be finish-machined by hard turning or using scroll-free turning technology, a final grinding process is the method of choice for thinner, more fragile parts. The required component quality, machining time (and therefore machining costs), tool costs and energy consumption differ depending on the process used and can be optimized with the VT 100 GT. The VT 100 GT adapts optimally to the respective machining requirements.
PERFECT SHAFT PRODUCTION FOR E-MOBILITY Turret Configuration:
+ 4 x turning tools + 1 x in-process gage + 1 x axial positioning probe + 1 x gripper Grinding Wheel:
+ Ø 400 mm + Vitrified bonded CBN Clamping at ID pitch cycle with clamping mandrel
Option TURRET WITH TWO WORKPIECE GRIPPERS Reduction of loading/ unloading time
BENEFITS + PRECISE
Complete machining ensures high component quality
+ INTEGRATED
Loading and unloading with the turret from the integrated raw and finished parts storage facility
+ RELIABLE
Vertical design prevents chip clusters
+ COMPLETE
Grinding (aluminium oxide or CBN), hard turning and machining with driven tools (including the Y-axis) – all hard processes can be run on a single machine
+ COMPACT
Machine has a small footprint
+ FAST
The tailstock and steady rests can be moved under the control of the CNC unit, thus reducing tooling and retooling times
