Diamond Wheels vs CBN Wheels. 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 ...
CBN Abrasive: A Guide to Cubic Boron Nitride. October 22nd, 2020. Cubic boron nitride (CBN) is a superb abrasive material designed specifically for advanced wear-resistant characteristics. It is a comparatively recent material innovation which has been earmarked as one of the greatest technological advancements of all time for abrasives.
A CBN grinding wheel uses Cubic Boron Nitride, or CBN, as its grinding material. Cubic Boron Nitride is considered a super abrasive. As the name suggests, super abrasives are stronger than normal abrasives like Aluminum Oxide and Silicon Carbide. CBN is best used to grind hard metals like: Steels with a hardness rating of at least 45Rc

CBN is used mainly for grinding high quality tool steels. Because of its chemical nature, CBN has no affinity for low carbon steels, being widely employed for grinding high-speed steels. CBN has an excellent thermal stability; oxidation starts above 1000 °C (1800 °F) and becomes complete around 1500 °C (2700 °F).
CBN can be used for hard machining without coolant, but in grinding, the use of a coolant is absolutely essential for technical reasons. If structurally changed layers appear, they often reach deep into the work piece in grinding.

Fig.3 Grinding ratio of different CBN grinding wheel on grinding different materials. 3 As can be seen from Fig.3a: 3.1 The grinding ratio of 6 kinds of CBN grains for cast iron HT250 materials is high, the grinding ratio is 147.9-213.9, of which CBN-B1500 is the highest and CBN850 is the second.
As CBN possesses higher wear resistance, lower grinding temperatures can be achieved, reducing the likelihood of thermal damage and residual stresses. Due also to the high thermal conductivity (1300 W/m.K), a small amount of heat is transferred to the workpiece (about 20 per cent), much lower than when alumina wheels are used (60–70 per cent ...
