Excellent Wear resistance , Higher impact resistance ,Toughness ,Thermal Stability low friction coefficient, low heat expansion coefficient, good strength and toughness. It can realize high speed cutting, hard material cutting and high precision processing. The PCD blank meets the requirement of environmental protection. Suitable for Laser cutting and EDM. Normal shape is round, can be cut into triangles ,rectangles ,square, sectors or as request PCD layer thickness is 0.5mm -0.70mm Available in overall thickness as followings: 1.2mm,1.6mm, 2.0mm, 3.2mm Available Grain size : 0.5-1μm,5μm,10μm,25μm,30μm,2-30μm 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, The cuttings will not attach to the tool during processing. Application: PCD blank for PCD turning tools, PCD boring tools, PCD reamers, PCD milling tools. The PCD blank is used in many different fields including aviation, the car industry, electronics, and the wood and stone industry. It applies to various materials such as nonferrous metal, tungsten carbide, ceramic, nonmetal and composite material. PCD blank selected according to your requirements .
