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

• Multi-spindle turning center with tool turret
• Vertical test setup

• Integration of further machining units through modular design
• Automatic loading and unloading of workpieces via pick-up
• Integration of in-process measuring equipment

• 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

• Simultaneous ID and OD machining of pot-shaped stator housings
• Substitution of separate OD machining processes (roughing)
• Reduction of cycle time: Semi-finishing up to 8 times faster compared to conventional turning processes
• Less re-clamping operations
• Efficiency increase of up to 100 % compared to conventional turning process
• Increase in economic efficiency
• Reduction of vibrations in the process

• E‑mobility stator housings
• Aluminum castings
• Heat sinks for hybrid engines
• Tube-flange couplings for the oil and gas industry
• Bearing and housing components for general mechanical engineering
• Workpieces for the plastics industry
