CBN

Description

Cubic boron nitride, henceforth abbreviated to CBN, is a synthetic crystalline material that is second only to diamond in terms of hardness. It is structurally analogous to diamond too, with a complex cubic/sphalerite structure composed of interpenetrating face-centred cubic lattices. CBN Abrasives: Common Applications
Although marginally softer than diamond, CBN abrasives are relatively inert and boast exceptional thermal stability under intense working conditions. They will not react when lapping ferrous metals. Nor are they prone to oxidation when grinding steel alloys. These combined properties make CBN grains the abrasive of choice for high-performance grinding wheels tasked with cutting or roughing cast iron, nickel-based alloys, and a wide range of steel grades.
