Due to its excellent performance, the proportion of titanium alloys used in the aerospace industry is increasing year by year, but due to the high cost of cutting and low processing efficiency, the current application is still limited. The physical and chemical properties of titanium alloy have brought difficulties to the cutting process. The specific characteristics of titanium total machining are as follows: First, the thermal conductivity of titanium alloy is low, only 1/4 of steel, 1/13 of aluminum, and 1/25 of copper. Due to the slow heat dissipation in the cutting area, it is not conducive to thermal balance. In the cutting process of titanium alloy parts, the heat dissipation and cooling effect is very poor, which is easy to form high temperature in the cutting area. After processing, the deformation and springback of the parts are large, resulting in increased torque of the cutting tool, fast edge wear and reduced durability. CNC Lathe processing.

Secondly, the thermal conductivity of titanium alloy is low, so that the cutting heat is not easy to distribute in a small area near the cutting knife, the friction of the rake face is increased, it is not easy to remove chips, the cutting heat is not easy to distribute, and the tool wear is accelerated.

Finally, titanium alloy has high chemical activity, and it is easy to react with tool material at high temperature, forming dissolution and diffusion, resulting in knife sticking, knife burning, knife breaking and so on. With the development of cutting tool materials and the continuous improvement of processing technology, the processing efficiency of titanium alloy parts will be greatly improved, and the processing cost will be significantly reduced, so that it has broad application prospects in shipbuilding, automobile manufacturing, chemical industry, electronics, marine development and other fields.
