CVD diamond excellent performance

CVD diamond as a cutting tool material favorable conditions for its unparalleled hardness is caused by the combination of excellent properties. With metal sintered PCD different is the unique nature of natural diamond in CVD diamond have been retained, even at high cutting temperatures also do so. Single crystal diamond hardness and  grinding cup wheel elastic modulus of a good result of CVD diamond wear resistance and dimensional stability.The silicon carbide "sand" test, the independent relative volume loss of CVD diamond PCD lower than 4 times, and 120 times lower than that of tungsten carbide. And metal bonding is not the same PCD compact, thick CVD diamond single crystal diamond material with high cutting temperatures in hardness and wear resistance comparable to or even exceed the single crystal diamond cutting at high temperature hardness and wear resistance Like the natural diamond CVD diamond has a small coefficient of friction generated during cutting and  concrete vibrator can consume a small cutting forces and less friction resistance and excellent heat resistance chip tumor.In dry cutting or high-speed machining, the high lubricating properties of CVD diamond cutting temperature resulting reduction of its superior PCD and other materials, the main favorable conditions. CVD diamond thick film applied to the mechanical aspects of the thermal conductivity of CVD diamond material is tungsten carbide efficiency five times higher thermal conductivity than the PCD 50%. CVD diamond excellent thermal  turbo diamond blade conductivity can be used as a safe route cooling the cutting area. Non-adhesive structure allows CVD diamond tool machining withstand temperatures up offensive 800 ℃, while cobalt sintered PCD when machining temperature close to 700 ℃, it will be heat damaged. Although the PCD can be filtered to prevent cobalt cobalt way resulting decline in the quality of PCD, CVD diamond but also has excellent wear resistance. With metal sintered PCD and tungsten carbide materials, non-binder structure and chemical properties of CVD diamond is more stable. CVD diamond coated cutting tools with synthetic materials such as phenolic resin polymer corrosive obviously has a longer life, CVD diamond cutting tool also against fluid corrosion.
