PCD tool processing
  PCD tool is the most commonly used cutting tool, and the remanufacturing process is quite strict. What is its processing? It`s slowly coming from Xiaobian.

PCD tool processing mainly consists of two stages: 1PCD composite sheet manufacturing: PCD composite sheet is made of natural or synthetic diamond powder and binder (including cobalt, nickel and other metals) at a high temperature (1000 ~ 2000 C ), sintered under high pressure (5 to 100,000 atmospheres).

During the sintering process, due to the addition of the binder, a bonding bridge with TiC, SiC, Fe, Co, Ni, etc. as the main component is formed between the diamond crystals, and the diamond crystals are embedded in the skeleton of the bonding bridge in the form of covalent bonds. The composite sheet is usually made into a disc of fixed diameter and thickness, and the sintered composite sheet is also subjected to grinding and polishing and other corresponding physical and chemical treatments. Processing of 2PCD inserts: The processing of PCD inserts mainly includes the steps of cutting the composite sheet, welding the blade, and sharpening the blade.




Processing range: non-ferrous metal drill reaming holes such as aluminum alloy, titanium alloy, graphite, copper alloy;Performance advantages of PCD tools


 1) The hardness of PCD can reach 8000HV, which is 80~120 times that of cemented carbide, and the wear resistance is better.
 2) PCD has a thermal conductivity of 700W/MK, which is 1.5 to 9 times that of cemented carbide. The heat transfer of the tool is rapid, and good heat transfer can greatly extend tool life.
 3) The coefficient of friction of PCD is generally only 0.1 to 0.3, and the friction coefficient of cemented carbide is 0.4 to 1, so PCD tools can significantly redu .optdiamondtools.com
