Cubic boron nitride(CBN) is a hardness second only to diamond superhard material. It not only has a diamond of many excellent characteristics,and has higher thermal stability and the iron group metals and their alloys chemically inert. It's hardness and chemical properties prompted the CBN is especially suitable for grinding Iron alloys.......

Description
Cubic boron nitride(CBN) is a hardness second only to diamond superhard material. It not only has a diamond of many excellent characteristics,and has higher thermal stability and the iron group metals and their alloys chemically inert. It's hardness and chemical properties prompted the CBN is especially suitable for grinding Iron alloys and other aerospace materials. Cubic boron nitride is used for metal processing of a large contribution, leading to the mill haircut born revolutionary change, is grinding technology is the second leap. currently has been widely applied to aerospace, automotive, military, wind power, metallurgy, electronics and other high-tech fields.
