Product overview

CBN( cubic boron nitride ), hardness is just second to diamond, but the thermal stability is better. CBN does not react with the iron family elements. Its hardness and chemical properties make CBN be the most desirable superabrasives crystal for grinding ferrous and other aeronautic materials.

CBN properties

High hardness, thermal stability and chemical inertness, as well as good infrared permeability, wider band gap and other excellent properties. Its hardness is second only to diamond, but thermal stability is better, it has better chemical stability to iron family elements. CBN has excellent grinding performance, which can process the difficult grinding materials, improve productivity, but also promote the grinding quality of the workpiece effectively.

CBN application:

Alloy Steel (HRC>50), Cast iron, Hardened Tool steel (HRC>50), Super Alloy (HRC>40), Stainless steel (HRC>50)
