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 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.

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

Liebherr solution

Gear hobbing machine LC 180 DC and LC 280 DC

The established LC 180 DC and LC 280 DC with integrated ChamferCut unit is a very compact gear hobbing machine. This integrated automation solution enables hobbing and simultaneous chamfering of workpieces with a maximum diameter of 280 mm and a module of 6 mm.

Gear hobbing machine LC 500 DC

With the LC 500 DC gear hobbing machine workpieces with a maximum diameter of 500 mm can be produced very economically, with a high gear cutting quality and precise chamfer quality. Workpieces up to module 7 mm can be hobbed and simultaneously chamfered.

Chamfering in the work area

The classic ChamferCut process with the chamfer cutters on the hob arbor can be retrofitted on all existing Liebherr gear hobbing machines with Siemens 840 D control and higher.
