Polycrystalline Diamond PCD
In our synthetic diamond product range, the polycrystalline diamond, also known as PCD, is synthesized by sintering the high quality diamond micron powder under the conditions of high pressure high temperature (HPHT).
PCD is the composite material with carbide based, has extremely higher wear resistance than traditional hard metal and ceramics, and the PCD tools can be reused by resharpening the cutting edges, in this way, the PCD tools have a much longer lifetime and a reduced machine downtime, which makes PCD become an ideal material and a cost-effective choice for tool makers to replace the hard metal and ceramics in woodworking and non-ferrous metals machining.
Production Process
The production process is strictly controlled from the very beginning of raw material preparation and mixing to the final ultrasonic scanning inspection of each PCD disc.
preparation and mixing of raw materials
assembly of composites
mixture’s purification and activation
HPHT synthesis
PCD blanks lapping and polishing
laser cutting
ultrasonic scanning inspection
