Diamond tool type - Dong Guan LSD Hardware Tools Co.,Ltd

Natural diamond tools are currently used for copper and copper alloy and gold, silver, rhodium and other precious non-ferrous metals, as well as special parts of the ultra-precision mirror processing, such as video discs, optical plane mirror, polygon mirror and secondary curved mirror. But its crystalline anisotropy, the tool is expensive. PCD performance depends on the diamond grain and cobalt content, tool life for the carbide (WC matrix) tool 10 to 500 times. Mainly used for turning a variety of non-ferrous metals such as aluminum, copper, magnesium and its alloys, hard alloy and wear-resistant fiber reinforced plastic materials, metal-based composite materials, wood and other non-metallic materials. Cutting speed, feed rate and cutting depth during cutting The machining conditions depend on the workpiece material and hardness. Artificial polycrystalline diamond composite sheet (PDC) performance and application close to PCD tool, mainly used in non-ferrous metals, carbide, ceramic, non-metallic materials (plastic, hard rubber, carbon rods, wood, cement products, etc.), composite materials Such as cutting, and gradually replace the carbide cutting tools. As the diamond particles asked some residual bond metal and graphite, in which the bonding metal to coalescence or leaf vein distribution will reduce the tool wear resistance and life. In addition to the presence of solvent metal residues, the solvent metal is in direct contact with the diamond surface. Reduce the (PDC) antioxidant capacity and tool heat resistance temperature, so the cutting tool performance is not stable enough. Diamond thick film tool preparation process is complex, because the diamond and low melting point metal and its alloys have a high interface between the energy. Diamond is difficult to be infiltrated by the general low melting point solder alloy. Welding is extremely poor, it is difficult to make complex geometric tool, so TDF welding tool can not be used in high-speed milling. Diamond-coated tools can be used for high-speed machining because, in addition to diamond-coated tools with excellent mechanical properties, the diamond coating process can produce any complex shape cutter for high-speed processing such as aluminum-titanium alloy aviation materials and difficult processing Metal materials such as graphite electrodes.
