PCD

Polycrystalline diamond.
Diamond tools have the characteristics of high hardness, high compressive strength, good thermal conductivity and wear resistance, and can obtain high machining accuracy and machining efficiency in high-speed cutting.
1, the hardness of PCD can reach 8000HV, 8 to 12 times that of cemented carbide;
2. The thermal conductivity of PCD is 700W/mK, which is 1.5 to 9 times that of cemented carbide, and even higher than PCBN and copper, so the heat transfer of PCD tools is rapid;
The friction coefficient of PCD is generally only 0.1~0.3 (the friction coefficient of cemented carbide is 0.4~1), so the PCD tool can significantly reduce the cutting force;
4. The thermal expansion coefficient of PCD is only 0.9 × 10 ^-6~1.18 × 10 ^-6, which is only equivalent to 1/5 of that of cemented carbide, so the Thermal Deformation of PCD tools is small and the machining accuracy is high;
5. The affinity between PCD tools and non-ferrous and non-metallic materials is very small, and the chips are not easy to bond to the tool tip to form chip accumulation during processing.
