PCD cutting insert

glassstonewood

PCD special insert has advantages of high hardness, high compressive strength, good thermal conductivity and good wear resistance, it can get high machining precision and machining efficiency during high speed machining. This PCD tipped insert can be used for processing stone, wood, metal composite materials, glass, engineering ceramics, and so on. Features of PCD Special Inserts Main performance index of PCD non-standard insert: 1. The hardness of PCD special insert is up to 8000HV, which is 80 ~ 120 times of hard alloys. 2. The thermal conductivity of PCD is 700W/mK, which is 1.5～9 times of hard alloys, even higher than PCBN and cupper, so the heat can be transferred quickly by PCD tool. 3. The friction coefficient of PCD is only 0.1～0.3 (friction coefficient of hard alloy is 0.4～1), so the PCD tool can reduce the cutting force significantly. 4. The coefficient of thermal expansion of PCD is only 0.9×10 -6～1.18×10 -6, which is equivalent to hard alloy 1/5, so the PCD cutting tool has small thermal deformation and high machining accuracy. 5. The affinity between PCD inserts and non-ferrous metals as well as non-metallic materials is very small, cuttings are not easy to be bonded on the tool tip during the process.
