Excellent performance of CVD diamond

An advantage of CVD diamond as a cutting tool material is its excellent combination of properties due to its unmatched hardness. Unlike metal sintered PCD, the unique properties of natural diamond are retained in CVD diamonds, even at high cutting temperatures. The hardness and modulus of elasticity of the single crystal diamond result in good wear resistance and dimensional stability of the CVD diamond.
In the silicon carbide "sand" test, the relative volume loss of the independent CVD diamond is four times lower than that of the PCD and 120 times lower than that of the tungsten cemented carbide. Unlike metal bonded PCD compacts, thick film CVD diamond materials are comparable to single crystal diamonds in hardness and wear resistance at high cutting temperatures, even exceeding the hardness and wear resistance of single crystal diamonds at high cutting temperatures. .
Like natural diamond, CVD diamond has a small coefficient of friction, resulting in less cutting force and functional consumption during cutting, as well as less frictional heat and superior anti-chipring properties.
In dry cutting or high speed machinery, the reduction in cutting temperature caused by the high lubricity of CVD diamond is a major advantage over PCD and other materials. The thermal conductivity of CVD diamond applied to mechanically thick film CVD diamond materials is five times higher than that of tungsten carbide and 50% higher than that of PCD. The excellent thermal conductivity of CVD diamonds can be used as a safe way to dissipate heat from the cutting zone. The non-binder structured CVD diamond allows the tool to withstand aggressive machining temperatures up to 800 ° C, while the cobalt sintered PCD is thermally damaged when the machining temperature approaches 700 ° C. Although PCD can be used to remove cobalt to prevent the degradation of PCD quality, CVD diamond also has excellent wear resistance. The chemical properties of non-binder structured CVD diamonds are more stable than metal sintered PCD and tungsten carbide materials. When a corrosive polymer such as a phenolic resin of a synthetic material is processed by a CVD diamond coating tool, it has a long life, and the CVD diamond can also resist corrosion of the cutting fluid of the tool.
