PCD Inserts

Type: PCD Overall Composite Inserts
Processed Material: Cemented carbide, glass fiber reinforced plastics, silicon filled materials, hard carbon fiber / epoxy resin composites, ceramics, wood, stone, hard carbon, artificial plates

In the 1970s, people synthesized polycrystalline diamond (PCD) using high-pressure synthesis technology, which solved the problem of scarcity and high price of natural diamonds, and expanded the application range of diamond tools to aviation, aerospace, automobiles, electronics, stone and many other fields.

The main material of PCD tool is diamond powder, which is produced by kneading ferrosilicon and other metals and binders at high temperature and high pressure. The hardness of the PCD tool is more than 100 times that of the ordinary cemented carbide tool.  It can reach> 8000HV. The heat conduction coefficient is 6 or 7 times higher.

PCD particle size is sub-micron, 2μm, 5μm, 10μm, 25μm and 2~30μm. CDW010 with 10μm particle size is general-purpose, with good chipping resistance and wear resistance. Generally, the larger the particle size, the more resistant the blade material The wear resistance of the CDW302 material with a mixed particle size of 2-30μm is better.

The application of PCD tools covers almost all areas of automotive aluminum alloy parts processing, including special ladder composite tools, cast aluminum and aluminum alloy processing taps


Characteristics Advantages
1.Better abrasion resistance. The hardness can reach 8000HV, which is 80 ~ 120 times that of cemented carbide.
2.Good heat transfer in large part to extend tool life. The thermal conductivity of PCD is 700W / MK, which is 1.5-9 times that of cemented carbide,

even higher than PCBN and copper.

3.More conducive to the removal of iron filings. PCD inserts friction coefficient is typically only 0.1 to 0.3, and the coefficient of friction of the

cemented carbide of 0.4 to 1.

4.Low thermal deformation of the tool, high machining accuracy.   PCD inserts has a small thermal expansion coefficient.
