Precision machining of aerospace industry for the high material requirements, in order to meet the particularity of aviation equipment and aerospace are affected by the environment, the special material of titanium alloy used in aerospace industry is more common.
Because of the small proportion of titanium alloy, it has a series of excellent physical and mechanical properties, such as low quality, high hardness and high thermal strength, high temperature resistance, sea water resistance and acid and alkali corrosion. In addition, the deformation coefficient of titanium alloy is very small, so it is widely used in aerospace, aviation, shipbuilding, petroleum, chemical industry and so on. Precisely because of the characteristics of titanium alloy is not the same as ordinary materials, it is difficult to determine the precision machining. Because of the small deformation coefficient, high cutting temperature, high stress and serious work hardening, the machine tool is easy to wear and collapse, which is difficult to guarantee the quality of cutting. How to cut it? Titanium alloy small thermal conductivity, high cutting temperature, non-standard tool wear large and low durability, so should be used with titanium chemical affinity, high thermal conductivity, high strength, grain tungsten cobalt carbide cutting tool is small, such as YG8, YG3 etc.. In the process of turning titanium alloy, chip breaking is a difficult problem in processing, especially the processing of pure titanium, in order to achieve the purpose of breaking chip, the chip curling groove cutting part into full arc edge, shallow deep, narrow wide, making chip more easily discharged, so as to avoid cutting wound on the surface of the workpiece, causing scratches on the surface of workpiece.
