1. Characteristics of titanium alloy

Titanium alloys have excellent strength, corrosion resistance, and biocompatibility, making them widely used in aerospace, medical devices, and other fields. However, its high hardness, low thermal conductivity, and chemical inertness also make titanium alloy processing somewhat difficult.

2. Processing methods for precision titanium alloy parts

(1) Traditional machining methods, including turning, milling, drilling, etc., are suitable for machining general shaped parts, but have lower efficiency for precision parts with complex structures.

(2) Non traditional machining methods, such as electrical discharge machining, laser machining, etc., can achieve precision machining of complex structures, but the equipment cost is high and the machining cycle is long.

3. Process technology for precision machining of titanium alloy parts

(1) Tool selection: High hardness and wear-resistant tools should be selected, such as PCD tools, end mills, etc., to improve machining efficiency and surface quality of the workpiece.

(2) Cooling and lubrication: Titanium alloy processing is prone to high temperatures, and appropriate cooling and lubrication methods such as cutting fluid cooling and dry cutting are needed to prevent workpiece deformation and tool damage.

(3) Processing parameters: including cutting speed, feed rate, cutting depth, etc., should be reasonably selected based on the specific material properties and processing requirements of titanium alloy to ensure processing quality and efficiency.

4. Common problems and solutions in precision machining of titanium alloy parts

(1) Cutting difficulty is high: methods such as increasing cutting speed and reducing cutting depth can be used to reduce cutting difficulty.

(2) Severe tool wear: Regular replacement of tools, selection of appropriate tool coatings, and other methods can be used to extend the service life of tools.

5. Conclusion

Precision machining of titanium alloy parts poses certain challenges, but by understanding the characteristics of titanium alloy, selecting appropriate machining methods and process technologies, processing efficiency and quality can be effectively improved, meeting the needs of different fields for precision parts.
