Thanks to its hardness and wear resistance the DIAMOND represents the best abrasive for the removal of hard materials that are difficult to process (usually short chipping) as hard metals, ceramics, hard alloys etc. 
During the grinding process of hard materials (usually over 50 HRC) such as hardened steels and cast irons, the CBN is the best abrasive; it guarantees the unchanging of the processed material.
