Product Name
PCD lettering knife, stone carving knife, diamond sharp knife.
PCD: PCD is mainly processing non-ferrous metal such as non-ferrous metal, can sharpen a sharp edge, get a better processing surface, generally can achieve a degree of 0.2 .

PCD scientific name polycrystalline diamond

Applications PCD Carving Tool
PCD Stone Engraving Cutters are mainly used for sculpture, cross inscription and character engraving on natural marble, granite, jade, milestone, ceramic tiles, glass, acrylic and metal materials.  and  PCD Flat Bottom Engraving cutter max tip width is 1.5mm, and max engraving depth is 5.5mm. Engraving knife with thinner tip is mainly used for sculpturing.
Engineering Features PCD Carving
PCD Stone Engraving Cutters were approved and honored by customers both at home and abroad  since its long service life, better abrasion resistance, edge sharpness performance, automatically surface roughness and stable quality.

1: PCD engraving tool hardness can reach 8000HV, 8~12 times that of cemented carbide;
2: PCD engraving tool has a thermal conductivity of 700W/mK, which is 1.5 to 9 times that of cemented carbide, even higher than PCBN and copper, so PCD cutter heat transfer is rapid;
3: The coefficient of friction of PCD engraving tools is generally only 0.1 to 0.3 (the friction coefficient of cemented carbide is 0.4 to 1), so PCD tools can significantly reduce the cutting force;
4: The thermal expansion coefficient of the PCD engraving tool is only 0.9×10^-6~1.18×10^-6, which is only equivalent to 1/5 of the cemented carbide. Therefore, the PCD tool has small thermal deformation and high processing precision.
5: The affinity between the PCD cutter and the non-ferrous metal and non-metal materials is very small. During the processing, the chips are not easy to adhere to the cutting edge to form a built-up edge.

SHK :means the diameter  of the tool hand
