1. The hardness of PCBN blank is 3,000HV to 5,000HV. The abrasive resistance of PCBN cutting tool is 50 times that of hard alloy cutting tool, 30 times that of coating hard alloy cutting tool and 25 times that of ceramic cutting tool.
2. The heat resistance of PCBN cutting tool can reach 1400 to 1500℃.
3. With high oxidation resistance, PCBN blank will not be oxidized under the temperature of 1000℃. Even under 1200 to 1300℃, PCBN cutting tool will not react to iron series material.
4. Its thermal conductivity is lower than diamond but it is higher than tungsten carbide.
5. The friction coefficient of PCBN blank is 0.1 to 0.3, while that of tungsten carbide is 0.4 to 0.6.

Features of PCBN Blank
