Description of CBN grinding wheel for hob grinding
JCB produces single bevel CBN grinding wheels for hob grinding. The grinding wheel is end-face ground, and the outer circle is very thin, which can be ground to the bottom of the edge. CBN grinding wheels are used for the shaping and grinding of high-speed steel (HSS) gear hobs and thread cutters (hardness above HRC60).
Advantages of CBN grinding wheel for gear hob - The grinding wheel adopts end grinding, the outer circle is very thin, and it can grind to the bottom of the edge
- Good wear resistance and low loss
- Dry grinding and wet grinding - High precision, reduced grinding force
