PCD compact blank is made of Polycrystalline Diamond and Carbide layer. They always have round shape and several grades. PCD compact blank are always cut into kinds of shape and dimension to make PCD cutting tools, such as PCD indexable inserts, PCD turning tools, PCD milling tools, PCD reamer, PCD woodworking tools, PCD saw blade and so on. 

Features

1. The hardness of PCD reaches 8000HV, which is 80 to 120 times that of tungsten carbide.
2. The thermal conductivity of PCD is 1.5 to 9 times that of tungsten carbide, and it is even higher than that of PCBN and copper. Its thermal conductivity is 700W/mK. The PCD blank can transfer heat fast.
3. The friction coefficient of PCD is only 0.1 to 0.3, while that of tungsten carbide is 0.4 to 1. The PCD cutting tool features small cutting force.
4. The heat expansion coefficient of PCD is 0.9*10-6 to 1.18 *10-6, which is only one fifth that of tungsten carbide. The PCD cutting tool features small thermal deformation and high processing precision.
5. The affinity between the PCD cutting tool and the materials, including nonferrous metal and nonmetal materials, is small. The cuttings will not attach to the tool during processing.
