Efficient machining of stator housings for e‑mobility
Newly-developed, patented process for efficient simultaneous machining of stator housings (inner housing) for E‑Mobility
- Semi-finishing up to 8 times faster
- Efficiency increase of up to 100 % compared to conventional turning process
- Compact Machine Mounting due to Vertical Machining
Innovation
-
Serial production solution for efficient ID and OD machining of pot-shaped stator housings by means of a simultaneous turning process
-
Substitution of separate OD turning processes (roughing) by an integrated process of ID and OD machining
-
Significant reduction in machining time
-
Increase in economic efficiency
Workpiece

Simultaneously Semi-Finish-Machining
-
Use of special internal boring tools and self-developed external bell tools, which enable machining of the inner and outer contour in parallel
-
Vibration-damped machining on the thin-walled workpiece through simultaneous operation of the inner and outer tools
-
Simultaneous rotary movement of workpiece and inner tool with stationary outer tool
-
Up to 8 times faster machining for the internal and external roughing processes due to simultaneous machining and higher number of cutting edges (4‑fold cutting edges)
-
Lower torque on the clamping device due to counter-rotating cutting forces of internal and external machining (compared to single internal machining)
-
Automated parts handling (pick-up)
-
Reduced re-clamping processes
