Diamond Wheels vs CBN Wheels

Coated Diamond

Diamond and CBN Wheels are currently fighting for the spotlight in the grinding industry. With an industry that mostly relied on Diamond, as the superabrasive choice for grinding difficult to grind (DTG) materials, CBN has quickly become a rival of diamond. Diamond is the hardest material known to man, but chemist have created a man made material that rivals the strength of diamond, which has become known as CBN. CBN stands for cubic boron nitride, a superabrasive that offers almost the hardness of diamond, cool cutting and the ability to work with ferrous materials, unlike diamond.


Diamond and CBN have the same crystal structure, with diamond consisting of pure carbon, whilst CBN is made up of the elements boron and nitrogen. Due to its carbon makeup, diamond is not able to properly grind ferrous materials. In contrast to Diamond, CBN has no carbon atoms, making it suitable for grinding ferrous materials. Our Diamond Wheels are particularly suitable for working with all grades of carbides, hard faced alloys, sapphire glass, graphite and many other materials. Our CBN Wheels are better suited for machining hardened steels, high speed steels, stellite and nickel based alloys and tool steels.
