Has a high thermal stability and high temperature hardness. CBN heat resistance of up to 1400 ~ 1500 ℃, at 800 ℃ when the hardness of Al2O3 / TiC ceramic at room temperature hardness, so when the cutting temperature is high, will make the material softened, and the hardness difference between the tool , Is conducive to cutting processing, and little impact on the life of the tool.
