CUBIC BORON NITRIDE

Product Description

SUKAN CBN is the most ideal abrasive for processing ferrous metal, since it has high toughness and heat resistance, chemical stability at interaction with ferrous metal. CBN is the second hardest known material, only diamond being harder. CBN is synthesised from hexagonal boron nitride under conditions similar to those used to produce synthetic diamond from graphite. The necessary characteristics of an abrasive include high hardness, abrasion resistance, strength and resistance to thermal and chemical attack while maintaining sharp cutting edges during use. Compared to conventional abrasives such as SiC and Al2O3, CBN is much more superior in all the fields. Its high thermal stability and resistance to chemical attack make it suitable for machining ferrous materials, an area where diamond abrasives are not normally utilized.
