How to improve the performance of synthetic polycrystalline diamond composite blade? Artificial polycrystalline diamond diamond composite blade is short PCD composite blade. PCD composite inserts need polycrystalline PCD polycrystalline material at high temperature and high pressure with metal binder such as cobalt. Although their hardness is lower than that of single crystal diamond tool, the randomly oriented polymerized diamond grains have To the same sex, to produce the PCD tool to handicrafts arbitrary orientation cutting, and do not have the characteristics of natural diamond tools.
In cutting, PCD tool cutting edge is not sensitive to accidental damage, abrasion resistance is very strong, able to maintain its sharp cutting state for a long time, machining can choose ultra-high cutting speed for grinding, its service life Than WC-based carbide tool to be 10-500 times higher. Because the PCD tool in the metal bond with conductivity, so that is more conducive to PCD tool for grinding and cutting. PCD cutter composite sheet and a wide source of raw materials, the price is not expensive, only a few one-tenth of natural diamonds, has gradually become the traditional high-performance WC-based carbide cutting tool alternatives.
In order to improve the toughness and weldability of PCD blades, it is necessary to sinter or press a layer of PCD composite sheet with thickness of 0.8mm on the surface of cemented carbide as its base. Because of its good weldability, it can be reused and costed Lower, has been widely used. But its processing tool surface of the poor workmanship, grinding than small, it is difficult according to the geometry of the head to make artwork arbitrary shape. Therefore, each tool has its own unique performance, and only choose the right tool to process their own products is the most important, Joe Diamond tool in accordance with the requirements of customers to customize the production of non-standard cutting tools
