A, CBN grinding tool has great thermal conductivity and thermal stability, whose thermal conductivity is 45 times of corundum and thermal diffusion is 112 times of corundum. CBN grinding tool is especially suitable for grinding heat-sensitive superhard high speed steel, high hardness alloy steel, etc., and does not produce grinding burn and cracks.

B, CBN grinding tool has strong chemical inertness and good stability. Especially when grinding quality tool steel, bearing steel, titanium alloy and nickel base alloy, it only has less abrasive wear, and does not need frequently to dress grinding wheel, whose durability is 100 ~ 150 times of grinding wheels.

C, The parts have good quality surface after grinding of CBN grinding tool, and do not produce grinding burn and defects such as cracks. They can improve the fatigue strength of parts, and prolong the service life about 30% ~ 50%. If CBN grinding tool is used to grind camshaft, the comprehensive costs will be reduced by 50%, and the fatigue strength will be increased by 30% on the surface of the camshaft.

Since the 1990s, with the emergence of high speed and ultra-high speed CNC grinding machine, high speed CBN grinding tool also has new development, instead of conventional corundum grinding wheel, widely used in mechanical processing. It is a kind of high performance grinding tool with high precision, high efficiency, low energy consumption, low production cost, low pollution, high degree of automation and other excellent performances, which is the development direction of modern grinding tools.
