Review on monolayer CBN superabrasive wheels for

2017-2-1  For example, Bhaduri and Chattopadhyay 15 have found that the uncoated wheel produced fracture wear during grinding low carbon steel (AISI 1020) and hardened bearing steel (AISI 52100), while the grain fracture was remarkably absent in the TiN coated wheel. The reason is mainly attributed to the resultant compressive stresses in the CBN grains ...
