Sharpening is made with numerical control machines using CBN grinding wheels for cold cutting with low roughness.

The pattern and radiality of cutting edges are respected, as well as the height of external blades compared with internal ones, which must be identical with a tolerance of 0.010 mm.
After sharpening, each part is DECOATED and coated again.
We offer TiN, ALTICROME and GearCut, according to the different customer requirements.
