    PCD Series

    Polycrystalline Diamond Compoct (PCD) for high-end cutting tools

    Advantages Of PCD Materials

    Polycrystalline Diamond Compoct (PCD) for high-end cutting tools

    • PCD has a hardness of 8000 HV, which is 80-120 times that of cemented carbide.
    • The thermal conductivity of PCD is 7000W/mk, which is 1.5-9 times that of cemented carbide, even higher than PCBN and copper.
    • The PCD friction coefficient is only 0.1-0.3 (the cemented carbide is 0.4-1), and the PCD cutter reduces the cutting force significantly.
    • The thermal expansion coefficient of PCD is 0.9*10-6-1.18*10-6, which is equivalent to one-fifth of that of cemented carbide. Therefore, PCD cutter has small thermal expansion coefficient and high precision.
    • The affinity between PCD and non-ferrous metals and non-metallic materials is very small, and it is not easy to bond on the tip of the blade, and it is not easy to form built-up edge.

    So PCD material cutter tools are widely used in high-speed and high-efficiency processing of non-ferrous metals and non-ferrous metal alloy materials.
