Micron & Coated Cubic Boron Nitride CBN Dust Powder

Description:

Cubic Boron Nitride (CBN) is a superhard abrasive with hardness second only to diamond and thermal stability better than diamond. Cubic boron nitride (CBN) will not react with iron group elements. Its hardness and chemical properties make CBN especially suitable for grinding ferroalloys and other aerospace materials. Cubic Boron Nitride processing materials: alloy steel (HRC > 50), cast iron, tool steel (HRC > 50), superalloy (HRC > 40), stainless steel (HRC > 50)

Cubic boron nitride is extremely hard, microhardness Hv72000~98000mpa, and hardness is lower than diamond. Like diamonds, cubic boron nitride is an insulator but an excellent conductor of heat. The structure is similar to the boron nitride morphology of the diamond, also known as the cubic boron nitride, c-bn, Β-bn, or z-bn (named after the crystal structure of sphalerite (Zinc Blende), is a widely used industrial drilling tool.

Improve grinding efficiency to a new level
CBN/cubic boron nitride powder is with high hardness and high temperature resistance, four times that of traditional abrasive in wear resistance, and have extraordinary thermal conductivity.
There are hundreds of raw materials needed to use CBN to grind in present manufacturing market, from aerospace superalloys and thermal spraying to the hardened steel in automotive bearing and gear industry to improve efficiency and get the shortest processing time.

Dark brown, irregular monocrystalline with sharp edge, tough and high thermal stability. Used in vitrified and metal bond systems, also used in heavy-duty resin bonds.

- cBN A60
Dark brown, blocky, very tough and high thermal stability. Widely used in metal bonds and electroplated tools.

- cBN A70
Gold in color, blocky, tough and high thermal stability. Widely used in metal bond and electroplated tools, better choice for hardened tool steel, cobalt-based alloys and super cobalt alloy.

- cBN A80
cBN80 series is our highest leval of cBN powder with high strength, high toughness, high stability and recommended for vitrified bond cBN grinding wheels processing auto camshaft and crankshaft, which is especially suitable for production of PCBN and cBN sintered body.

- CBN A80M Micron Size

A80M is now the higher level of CBN powder in China, with high toughness, high stability, which is the best choice for vitrified bond CBN grinding wheel processing aturo camshaft and crankshaft. Therefore, A80M has strong grinding force and much better stability than other CBN micronpowder. The cleanliness of the surface through special processing is especially suitable for the production of PCBN and CBN sintered body.
