cbn turning inserts

Description

The PCD blank has the advantages of high hardness, high abrasive resistance, high thermal con ductivity, 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.Our PCD blank is manufactured by world famous companies such as Element Six (DeBeers), DI (GE), ILJIN, SMITH, SUMITOMO and TOMEI. We also offer laser engraving service of PCBN blank.

Features1. 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.

ApplicationThe 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.

MaterialThe PCD blank uses diamond powder and tungsten carbide.
