PCD Grooving Tool for Pistons

(1) The hardness of PCD can reach as high as 8000HV, which is 8 to 12 times of cemented carbide.
(2) The thermal conductivity of PCD is 700W/mk, 1.5 ~ 9 times of cemented carbide,even higher than PCBN and copper alloy;
(3) The friction coefficient and expansion coefficient of PCD are small;
(4) PCD and non-ferrous metals and non-metallic materials, the affinity between small;
(5) Sharp edge and blade surface roughness
