Polycrystalline Cubic Boron Nitride Composite Sheet

Polycystalline Cubic Boron Nitride Composite Sheet (PCBN) has high hardness and wear resistance. The hardness of PCBN is generally HV3000-5000, and the heat resistance can reach 1400-1500 ℃. It also has good red hardness and high anti oxidation ability. Polycystalline PCBN does not undergo oxidation at 1000 ℃ and does not undergo chemical reactions with iron-based materials at 1200-1300 ℃. The thermal conductivity of tools made of PCBN is lower than that of diamond but much higher than that of hard alloy, which is beneficial for improving the machining accuracy and surface smoothness of workpieces. The friction coefficient of tools made of PCBN for processing different materials is between 0.1 and 0.3, which is much lower than that of hard alloy (0.4 to 0.6), making it less likely for CBN tools to form retention layers or chip deposits during cutting.
