Polycrystalline diamond (PCD) is an artificially created material made in the super high pressure/super high temperature environment. It has Vickers hardness (Hv) of 9,000 or more, and it is indispensable for cutting high wear resistant difficult-to-cut materials. The most likely workpiece for which PCD tools are used can be aluminum and aluminum alloy. Due to its blade nature and non-weldability to aluminum, PCD is used to process parts of many automobiles and consumer electronics products where aluminum products are heavily used. The PCD types that Chukyo usually has in stock are as follows.
