Diamond cutting tools have the advantages of extremely high hardness and abrasion resistance, low friction coefficient, high elastic modulus, high thermal guidance, low thermal expansion coefficient, as well as small affinity with non -iron metal. It can be used for precision processing of non-metallic hard and crisp materials such as graphite, high wear resistance, composite material, high silicon aluminum alloy and other tough color metal materials. There are many types of diamond cutting tools with significant performance differences, and there are large differences in the structure, preparation methods and application fields of different types of diamond tools. Applications
Natural diamond tools are mainly used for valuable metals such as copper and copper alloy and gold, silver, and crickets, as well as ultra -precision mirrors of special parts, such as camera disks, optical plane mirrors, multi -faceted mirrors, and secondary curved mirrors. However, its crystals are different, and the tools are expensive. The performance of PCD depends on the content of diamond grains and cobalt, and the tool life is 10 to 500 times that of a hard alloy (WC substrate) tool.
Diamond cutting tools are mainly used to run various non -metal materials such as aluminum, copper, magnesium and its alloys, hard alloy and abrasion resistance, and non -metal materials such as metal -based composite materials, and wood. The cutting speed, feed speed, and cutting depth processing conditions of cutting depends on the material and hardness of the processing speed, and cutting depth processing conditions. The performance and application of artificial polystalline diamond composite (PDC) are close to PCD tools, mainly used in non -ferrous metals, hard alloys, ceramics, non -metallic materials (plastic, hard rubber, carbon rods, wood, cement products, etc.), composite materials, etc.), composite materials, etc. Wait for cutting, gradually replace the hard alloy knife. Because there are some residual adhesive metals and graphite between diamond particles, the adhesive metal is reducing the wear resistance and life of the tool with a clustering state or a leaf vein distribution. In addition, there is a residual volume of solution metal, and the solution metal and diamond surface are directly exposed to contact. Reduce the antioxidant capacity of (PDC) and the heat -resistant temperature of the tool, so the cutting performance of the tool is not stable enough. The preparation of diamond -thick film tools is complicated, and there is a high interface energy between diamond and low -melting point metal and its alloy. Diamond is difficult to be infiltrated by general low -melting welded alloys. Weld-ability is extremely poor, and it is difficult to make complex geometric shapes. Therefore, the TDF welding tool cannot be applied to high-speed milling. Metal materials such as graphite electrodes. Contact us for more diamond cutting tools info now!
