Fabrication Process Of Polycrystalline Diamond Cutter
- Apr 27, 2017 -

The manufacturing process of PCD cutter consists of two phases: ① manufacturing of PCD composite tablets: PCD composite tablets are made from natural or synthetic diamond powders and bonding agents (including cobalt, nickel and other metals) in a certain proportion at high temperatures (1000 2000), high-pressure (5~10 10,000 atmospheric pressure) under sintering. In the sintering process, due to the addition of the binder, the formation of diamond crystals between tic, SIC, Fe, CO, ni, etc. as the main components of the combination bridge, diamond crystal in the form of covalent bonding in the skeleton of the bridge. The composite plates are usually made of a fixed diameter and thickness disc, and the sintered composite plates should be polished and other corresponding physical and chemical treatments. ② PCD blade Processing: PCD blades processing mainly include composite pieces of cutting, blade welding, blade grinding and other steps.
