What are PCD and diamond cutting tools?

PCD material is called Polycrystalline diamond, is a kind of new superhard material which is studied and researched in the 1970s. It can be sintered at a high temperature of 1400℃ and high pressure of 6GPa.

The diamond grit that has been fused together under high-pressure, high-temperature conditions in the presence of a catalytic metal. The extreme hardness, wear resistance, and thermal conductivity of diamond make it an ideal material for the cutting tools manufacturing.

​

Polycrystalline diamond is not only a kind of new engineering material but also a kind of new functional material. It is not only a high-tech product but also a high-benefit product. With the development of modern industry and science and technology, polycrystalline diamond has been widely used in modern industry, national defense and high-tech fields because of it”s excellent mechanical, thermal, chemical, acoustic, optical and electrical properties.
