CBN END MILLS
1. CBN is the only materials human knows now that its hardness is second only to diamond,its htermal stability & chemical interness is much better than diamond, can withstand 1300-1500°C ,even at °C,it does not happen phase change
2. CBN has low affinity with iron-based metal,so it can be used for the high speed cutting of iron-based metal,high precision & surface finished,cutting speed is 10 times than carbide,hardness& wear resistance is 50 times than carbide cutting tool ,25 times than ceramic tool.
