How to Titanium Alloy Cutting Machining?

Due to the small deformation coefficient of titanium alloy, high cutting temperature, large tool tip stress and serious work hardening, the tool is easy to wear and chip during cutting, and the cutting quality is difficult to guarantee. How to do cutting titanium machining?

1.When cutting titanium alloys, the cutting force is not large, the work hardening is not serious, and it is easy to obtain a better surface finish, but the thermal conductivity of titanium alloys is small, the cutting temperature is high, the tool wear is large, and the tool durability is low. Small chemical affinity, high thermal conductivity, high strength, small grain size tungsten-cobalt carbide tools, such as YG8, YG3 and other tools. In the process of turning titanium alloys, chip breaking is a difficult problem in processing, especially the processing of pure titanium. In order to achieve the purpose of chip breaking, the cutting part can be ground into a full arc chip flute, with shallow front and deep back, and narrow front. The width of the back makes the chips easy to discharge outward, so that the chips will not be wrapped around the surface of the workpiece and cause scratches on the surface of the workpiece.

2.Titanium alloy cutting deformation coefficient is small, the contact area between the tool and the chip is small, and the cutting temperature is high. In order to reduce the generation of cutting heat, the rake angle of the turning tool should not be too large. The rake angle of the carbide turning tool is generally 5-8 degrees. Due to the high hardness of titanium alloy, in order to increase the impact strength of the turning tool, the clearance angle of the turning tool should not be too large, generally 5°, in order to strengthen the strength of the tip part, improve the heat dissipation conditions, and improve the impact resistance of the tool , a negative edge inclination with a larger absolute value is used.

3. Controlling a reasonable cutting speed should not be too fast, and using special cutting fluid for titanium alloys to cool during processing can effectively improve tool durability and select a reasonable feed rate.
