Precautions for machining titanium alloy workpieces

The machining process of titanium alloy is heavy-duty cutting, so the machine tool spindle has high driving force and strong cutting function. In the aerospace industry, the processing of titanium alloy parts is mainly in the milling of cavities.
Multiple aspects need to be considered during the machining of titanium alloy components to ensure machining quality and efficiency.
Titanium alloys have a low thermal conductivity. During machining, heat easily accumulates on the local surface of the workpiece, causing the tool temperature to become too high, which may result in "tool burning." Therefore, high-quality tools are required, and the cutting speed should be low; that is, a low-speed, low-feed machining method should be used. Use tools specifically designed for titanium alloys; if unavailable, cemented carbide tools can be used, with the higher hardness the better. At the same time, because titanium alloy machining tools have high hardness, dense texture, and good heat transfer, the use of coated tools should be avoided as much as possible to prevent a "affinity" reaction between the titanium alloy and the titanium in the coating, causing "tool sticking."
Titanium alloys have low density and hardness, and the material is soft and easily "yields to the tool." During rough machining, it may be "unable to cut sufficiently," but it will not "overcut." To avoid this situation, leave as little allowance as possible to improve machining efficiency. Cooling measures must be taken during titanium alloy machining to prevent the tool tip temperature from becoming too high, causing the coating to peel off. This is even more important during fine machining with small amounts of cutting; titanium alloy chips will "burn" at higher temperatures, affecting the quality of product formation.
In addition, titanium alloys have high chemical activity and easily combine with gaseous impurities at high temperatures, forming an embrittlement layer and increasing the difficulty of processing. Therefore, appropriate cutting parameters and cutting fluid must be selected to ensure that the machining process proceeds smoothly.
In summary, titanium alloy machining requires the correct selection of tool materials based on material properties, maintaining tool sharpness, using good cooling processes, and strictly following relevant machining standards.
