Feb 13, 2015 · CBN (Knoops hardness 4,700) is considerably harder than alumina and silicon carbide; due to its low wear rate, it produces the required profile and geometric tolerances in most instances. Maximum cost effectiveness of CBN is achieved when grinding hardened high alloyed, difficult to grind steels over 60 HRC e.g. tool or chrome steel.

The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measuring the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). There are different scales, denoted by a single letter, that use different loads or indenters.

it is often necessary to increase the hardness of the steel. According to AGMA standards, Ia gear with a hardness of 400 BHN, which has a design life of 10 7 cycles can handle as much as 20% more load than a gear which is hardened to 300 BHN. For hardnesses above 400 BHN the capacity increases with respect to pining resistance. but the capacity
