Polycrystalline diamond tool manufacturing process

PCD tool manufacturing process consists of two phases: ① PCD producing a composite sheet: PCD composite sheet is made from natural or synthetic diamond powder and binding agent (which contains cobalt, nickel and other metals) by a certain percentage at high temperature (1000 ~ 2000 ℃), pressure (5 to 100,000 atmospheres)  synthetic diamond . In the sintering process, due to binding agent is added, between the diamond crystals to form TiC, SiC, Fe, Co, Ni, etc. as a main  cubic boron nitride  with the bridge, the diamond crystals to form a covalent bond with the bridge mounted on the skeleton. The composite sheet is usually made ​​from a fixed  Diamond blade  and the thickness of the disc, the need for sintering the composite sheet for grinding and polishing and other appropriate physical and chemical treatment. ② PCD inserts for machining: PCD inserts composite sheet processing including cutting, welding blade, blade sharpening and other steps.
