The JCB PCBN composite sheets are formed by sintering mixed high-quality, high-strength CBN Micro-powder with various bonding agents onto a carbide substrate under ultra-high temperature and pressure conditions. Their service life is 10 to 25 times that of carbide tools. JCB PCBN composite sheets are widely used in cutting processes across industries such as military, automotive, metallurgical rollers, bearings, and molds.
The PCBN composite sheets produced by our company exhibit extremely high hardness, excellent high-temperature resistance, and strong chemical inertness. They do not react chemically with ferrous metals even at high temperatures, combining the high hardness, wear resistance, and high-temperature resistance of CBN with the impact toughness of carbide. Their service life is 10 to 25 times that of carbide tools. They are primarily used for machining various types of cast iron, hardened steel, powder metallurgy, and other difficult-to-machine materials. They are widely applied in cutting processes across industries such as military, automotive, metallurgical rollers, bearings, and molds.
