diamond is difficult to geometries Tool

Diamond Tool preparation process is complex, because the diamond between the low-melting metals and their alloys have a high interfacial energy. Diamond is difficult to be generally low melting point solder alloy infiltration. Weldability poor, difficult to produce complex geometry tool, it can not be applied TDF welding tool in high-speed milling.
Natural diamond tools currently used carbide grinding wheels  mainly for copper and copper alloys and gold, silver, rhodium and other precious metals, and special parts of the ultra-precision mirror processing, such as a disk recorder, an optical mirror, a polygon mirror and the second curved mirror and so on. But its crystalline anisotropy, the tool expensive. PCD performance depends on the content of diamond grains and cobalt, cemented carbide tool life (WC substrate) of the tool 10 to 500 times. Mainly used for a variety of non-ferrous metals such as turning of aluminum, copper, magnesium and its alloys, tungsten carbide and wear strong fiber reinforced plastic materials, metal matrix composites, wood and other non-metallic materials. When cutting speed, feed rate and depth of cut depends on processing conditions and the hardness of the workpiece material. Synthetic polycrystalline diamond compact (PDC) properties and applications close PCD tool, mainly used in non-ferrous metals, tungsten carbide, ceramics, non-metallic materials (plastic, hard rubber, carbon rod, wood, cement products, etc.), composite materials such as cutting, gradual replacement carbide cutting tools. Because the diamond particles bonded to ask some residual metal and graphite, in which the bonding metal or showed coalescence vein-like distribution state will reduce tool wear and life. In addition there is a metal residue solvent, solvent metal in direct contact with the diamond surface. Lower (PDC) oxidation resistance and tool heat resistance, the cutting tool is not stable enough. Diamond-coated tools can be table saw blades  applied to high-speed machining, because in addition to diamond coated tools have excellent mechanical properties, diamond coating process can be prepared any complex shape cutters for high speed machining aerospace materials such as aluminum alloy and refractory processing of non- metallic material such as graphite electrodes. Vitrified diamond grinding wheel with diamond and vitrified common characteristics, and general corundum, silicon carbide abrasive compared to its strong grinding, grinding temperature is relatively low, abrasive wear is relatively small; can be adapted to a variety of The role of the cooling fluid; grinding abrasive good shape retention, high precision grind the workpiece; abrasive there are more pores, grinding and heat conducive chip, clogging, easy to burn the workpiece; mill with good self-sharpening, finishing a long time interval, trimming easier. Therefore, vitrified diamond grinding wheel used hole saw blades  in some foreign countries is increasing. Select reasonable parameters, vitrified diamond wheel grinding single crystal diamond, grinding efficiency than metal bonded grinding wheel high, wear ratio is very small, low cost, so the use of ceramic bonded grinding wheel grinding single crystal diamond, can greatly improve Happening grinding efficiency. PCD tools in the grinding, since the binder resin is relatively soft, easily deformed when grinding, grinding of PCD tools can not be effectively; metal bonded abrasive due to too strong binding ability of leaving the poor self-sharpening abrasive, grinding low efficiency, and metal bonded grinding wheel will cause the edges of PCD tool most serious damage; integrated grinding efficiency, durability and abrasive machining the workpiece surface quality vitrified diamond grinding wheel PCD tool is the most appropriate choice.
