In the video below our gear hobbing machine Koepfer K160 CNC is skiving a 1.25, 9-teeth 58HRC gear module.
As many of you probably know, tooth hobbing referred to as skiving is a recent concept used for finishing the side of the gear teeth as to eliminate any deformations caused by thermal treatment.
But given that it’s performed after a thermal treatment, this operation generates a number of different issues. For instance – as in this case – having to work on a cemented piece with a hardness of up to 58HRC. Other issued to be addressed generally refer to the piece clamping equipment, the wear of the tools, the vibrations and so forth.
Given our extensive experience in this sector, however, we were able to resolve all these issues – one by one – and we can now propose the equipment on a market which shows an increase in demand for these types of solutions, and an excellent compromise for intermediate quality of rectification.
