DIAMOND Pcbn Cutting Tool Blanks, Brand Name : More super

Description
The PCBN blank has the advantages of high hardness, high thermo stability, high chemical stability, good strength and good weld ability. The PCBN cutting tool can realize high speed cutting, hard material cutting and dry cutting. It can precisely process the products and replace grinding with turning. The PCBN cutting tool meets the requirements of environmental protection.
We also offer laser engraving service of PCBN blank.
Features
1. The PCBN blank features high hardness and high abrasive resistance. The hardness of PCBN blank is 3,000HV to 5,000HV. The abrasive resistance of PCBN cutting tool is 50 times that of tungsten carbide cutting tool, 30 times that of coating tungsten carbide cutting tool and 25 times that of ceramic cutting tool.
2. The PCBN blank has high thermo stability and heat resistance. The heat resistance of PCBN cutting tool can reach 1400 to 1500℃.
3. The PCBN blank has high chemical stability. With high oxidation resistance, PCBN cutting tool 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. The PCBN blank features good thermal conductivity. Its thermal conductivity is lower than diamond but it is higher than tungsten carbide.
5. The PCBN has low friction coefficient. The friction coefficient of PCBN is 0.1 to 0.3, while that of tungsten carbide is 0.4 to 0.6.
