Cubic Boron Nitride Grade CBN A80 Widely Used For Grinding Wheel

Dark Brown CBN A80 Cubic Boron Nitride 40-400 mesh

Description:

Cubic Boron Nitride powder, used in precision grinding, grinding, polishing and ultra-finishing to achieve high-precision machined surface.
Applicable to resin, metal, ceramic and other binding agent system, can also be used for the production of poly-crystalline composite sheet sintered body, it can use as loose abrasive particles, abrasive paste. The black cubic boron nitride CBN has excellent chemical and physical properties, such as the high hardness after diamond, thermal stability and chemical inertness, as superhard abrasive in different industries to obtain a wide range of applications, is now becoming the automotive, aerospace, mechanical electronics, microelectronics and other industries indispensable important materials, therefore, the industrial developed countries have received great attention. There are many methods for synthesizing CBN in addition to static high pressure catalyst, such as static high pressure direct conversion method, dynamic impact method, vapor deposition method, and some methods such as vapor deposition method develop rapidly. But so far the main method of industrial synthetic CBN is static high pressure catalyst method, the synthesis of CBN is mainly focused on this aspect.

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.
