Cubic boron nitride (CBN) is also a ultrahard abrasives. Its microscopic hardness is second only to that of synthetic diamond. CBN possesses good thermal stability and chemical inertness relating to the metals of the ferric family. CBN can be manufactured into all kinds of bonded grinding wheels and electroplated tools. It can be used in processing various kinds of hard and tough steels such as high-speed steel, high-vanadium steel and bearing steel, and so on.

We can supply quality Cubic Boron Nitride for different purpose. And grits abailable are as following:
40/50, 60/80, 80/100, 100/120, 120/140, 140/170, 170/200, 200/230, 230/270, 270/325, 325/400
