Product catalog summary
ChamferCut Technology Overview
The ChamferCut process is a precise and cost-effective method for chamfering gears, offering high-quality chamfer geometry without material deformation. It is widely used in gear production due to its long tool life and the ability to re-sharpen tools up to 20 times, reducing overall tool costs.

Advantages
  • Precise chamfer geometry and high reproducibility.
  • No bulging or material deformation.
  • Standard tooth-root chamfering.
  • Long tool life and cost-effective re-sharpening.
  • Applicable for gears with module 0.8 – 42 mm.
  • No need for a second cut, enhancing tool life.
  • Short setup times.

Profitability Analysis
The ChamferCut process significantly reduces tool costs per workpiece compared to traditional press chamfering methods. For example, with a chamfer cutter set costing €3,600 and allowing 23 re-sharpenings, the tool cost per workpiece is reduced to 1.5 cents, resulting in substantial annual savings.

The ChamferCut process-2

Chamfer form with the traditional chamfering method Precise – reliable – cost-effective. This is the chamfering process 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 deformationbased 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...
