Ultra-high speed machining of titanium alloy (3)
c. Matching of ultra-high-speed cutting titanium alloy with tool materials According to the requirements of titanium alloy itself for tool materials and special requirements for tool materials for ultra-high-speed cutting; several common tool materials and titanium alloys suitable for ultra-high-speed cutting have been found. The matching is very different.

Tool Material PCD Coated Carbide PCBN TiC(N) Based Carbide Ceramic Tool Excellent matching performance Not suitable Not suitable PCD tool performance is suitable for processing titanium alloy: 1 very good thermal conductivity, due to thermal conductivity and heat The diffusion rate is high, and the cutting heat is easily dissipated, so the cutting temperature is low, and the thermal conductivity of the diamond is 1.5 to 9 times that of the cemented carbide. 2 The lower coefficient of thermal expansion, the coefficient of thermal expansion of diamond is several times smaller than that of cemented carbide, which is about 1/10 of that of high-speed steel. 3 extremely high hardness and wear resistance, diamond tools in the processing of high hardness materials, the durability of cemented carbide tools 10 to 100 times, and even up to hundreds of times.
3 Conclusion
The use of ultra-high-speed cutting of difficult-to-machine materials titanium alloy solves the problem of conventional cutting of titanium alloy, which not only ensures the processing quality but also greatly improves the productivity, and has a good development prospect. Ultra-high-speed cutting technology is gradually maturing for the processing of difficult-to-machine materials. How to further improve the processing technology of ultra-high-speed cutting titanium alloy is a subject to be further studied.
