High Strength High Hardness CBN Abrasives for Grinding Wheel Making

Cubic Boron Nitride, that is CBN, is kind of synthetic super hard material. With a high hardness of hv7200-9800mpa, its hardness is just lower than that of diamond. Like diamonds, CBN is an insulator but an excellent heat conductor. The structure of the boron nitride form is similar to it of diamond, also known as cube boron nitride, c-BN, β-BN, or z-bn. It is widely used as an industrial drilling and grinding tool.

Various black, amber and brown CBN in different sizes can be supplied as following:

CBN grit: 50/60, 60/70, 70/80, 80/100, 100/120, 120/140, 140/170, 170/200, 200/230, 230/270, 270/325, 325/400 mesh

CBN micron powder: 1-3, 2-3, 2-4, 3-6, 4-8, 5-10, 6-12, 7-14, 8-16, 10-20, 12-22, 15-25, 20-30, 22-36, 30-40, 35-45, 40-60 micron

Characteristics of CBN 

Cubic boron nitride (CBN) is a superhard material, which hardness is next to that of diamond. It not only has many excellent properties as diamond, but also has higher thermal stability and chemical inertness to ferrous metals and alloys. As an engineering material, it has been widely used in ferrous metal and its alloy material processing industry. Meanwhile, the CBN has been applied in a series of high-tech fields with its excellent thermal, electrical, optical and acoustic properties, and has become a functional material with development prospects.

Application of CBN 

Cubic boron nitride powder is used in precision grinding, polishing and ultra precision machining to achieve high precision machining surface. It is suitable for resin, metal, ceramic and other binder systems, as well as for the production of polycrystalline composite sinter, loose abrasive and grinding paste.

With excellent chemical and physical properties, such as high hardness, high thermal stability and chemical inertness, the black CBN has been widely used as superhard abrasives in different industries, and now it has become an indispensable important material in automobile, aerospace, mechanical electronics, microelectronics and other industries, so it has also been developed in various industries The state attaches great importance to it.
