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.

 

what's the advantage of PCD tools?

The diamond cutting tool has become an indispensable tool in the modern cutting process, which is mainly shown in the following aspects:

1. High-speed cutting, high stability processing

2. Ultra-precision mirror processing

3. Dry cutting, clean machining

Common Applications for PCD:

  • Aluminum and aluminum alloys

  • Copper, brass and bronze alloys

  • Zinc and magnesium alloys

  • Carbon Fiber

  • Epoxy resins

  • Plastics

  • Fiberglass composites

  • Graphite composites
