JCB PCBN composite sheet is a composite blade formed by mixing high quality and high strength CBN micropowder and various types of binders sintered on the cemented carbide matrix under ultra-high temperature and high pressure conditions, and its service life is 10 to 25 times that of cemented carbide tools. JCB PCBN composite sheet is widely used in military, automotive, metallurgical roll, bearing, mold and other industries cutting processing.
The PCBN composite sheet produced by our company has high hardness, high temperature resistance and strong chemical inertness, and will not react with ferrous metal at high temperature, which has both high hardness, high wear resistance and high temperature resistance of CBN, and has the impact toughness of cemented carbide, and its service life is 10 to 25 times that of cemented carbide cutting tools. Mainly used for processing all kinds of cast iron, hardened steel, powder metallurgy and all kinds of difficult materials, etc., widely used in military, automobile, metallurgical roll, bearing, mold and other industries cutting processing.
