Precise – reliable – cost-effective
This is the chamfering process.
Advantages
The ChamferCut process
- Very precise chamfer geometry
- Premium chamfer quality and reproducibility
- No bulging or material deformation
- Standard tooth-root chamfering
- Established process in gear production
- Very long tool life
- ChamferCut tools can be re-sharpened approx. 20 times easily and cost-effectively
- Lower tool costs compared to alternative processes
- Short amortization period due to low tool costs
- Applications for gears with module 0.8-42 mm
- 2nd cut not needed for gear hobbing - longer tool life for the hobbing tool
- Short setup time

After chamfering with the patented ChamferCut technology, no additional machining is necessary. There is no need for a second cut, which is often required during the deformation-based deburring process for the removal of build-up material. With the chamfering process, the exact chamfer form is produced. In contrast to deformation-based processes, the material structure is not affected. An optimal starting point is created for the subsequent finishing of hardened gears, particularly gear honing. The quality of such chamfers defines a new standard – with maximum repetitive accuracy.
