PCD Disc

Product Detail

PCD disc

Besharp Diamond is a professional manufacture of long life and high efficiency PCD disc




1.Product Introduction of PCD disc

PCD disc consists of PCD layer integrally sintered at ultrahigh pressure and high temperature to a cemented tungsten carbide backing. It has the high hardness and abrasion resistance of nature diamond, and combines with the toughness that of tungsten carbide. Its life is 10 to 100 times of tungsten carbide cutters.

3.Product feature and application of the PCD disc

Feature

Ø  High hardness:The PCD hardness can reach 8000HV,it is 8 to 12 times of tungsten carbide cutters

? Good thermal conductivity:the coefficient of heat conductivity of PCD is 700W/mK,it is 1.5 to 9 times of tungsten carbide,even higher than PCDBN and copper,so the heat generated during PCD cutting tools working transfer quickly.

? Small  friction coefficient:the PCD friction coefficient is 0.1-0.3,the carbide  friction coefficient is 0.4-1,so the PCD can reduce the cutting force remarkably

? Low Coefficient of thermal expansion:the PCD is 0.9×10^-6~1.18×10^-6,it is only 1/5 of tungsten carbide,so the PCD has small thermal deformation,and it higher working accuracy

? small affinity:PCD has small affinity for non-ferrous metal and nonmetal materials,so will has smaller and stabler silver white chip formation
