Cubic Boron Nitride Abrasives (CBN)

Cubic boron nitride (CBN), a synthetic super hard abrasive second only to diamond, is ideal for grinding ferrous materials because it does not carbonize when interacting with iron like diamond abrasives. Typically, CBN is used to grind bearing steel, cast iron, die steel, tool steel, super alloys, and in some cases ceramic materials.

The difference between CBN abrasives and ordinary abrasives.

The hardness of CBN is much higher than that of ordinary abrasives, so it can process a variety of materials with higher hardness and toughness, especially materials that are difficult to process with ordinary abrasives;

1. Less wear, long service life, high grinding ratio, and better economic benefits;

2. When in use, the shape and size change relatively slowly, which is conducive to grinding operations, saves auxiliary man-hours, and is more suitable for automatic line processing of high-precision parts;

3. It can maintain a sharp cutting edge with low grinding force, which is beneficial to improving the precision and smoothness of parts and reducing the power consumption of machine tools;

4. Low grinding temperature can greatly improve the surface quality of the work piece and avoid defects such as cracks, burns, and structural changes in the parts. Improve the stress condition of the machined surface and extend the service life of the parts.
