The processing of titanium alloy sheet metal mainly includes material cutting, stamping, bending, stretching, welding, surface treatment, and other links. Due to the high chemical activity and low thermal conductivity of titanium alloys, processing hardening, cracking, and tool wear are prone to occur during processing, so high requirements are placed on processing technology and equipment.



Firstly, in the material cutting stage, commonly used methods include laser cutting, plasma cutting, and water jet cutting, etc. Laser cutting has high precision and a small heat-affected area, is suitable for precision cutting of complex shapes, and is currently a more ideal choice.



Secondly, during the stamping and stretching process, due to the poor plasticity of titanium alloys and the large deformation resistance, higher forming forces and reasonable mold design are required, and appropriate lubrication measures should be taken to reduce friction and mold wear. At the same time, heating forming is also a commonly used method, which helps to improve the plastic deformation ability of titanium alloys.

　　In terms of bending and forming, the bending angle and radius should be adjusted according to the mechanical properties of the titanium alloy material to avoid dimensional deviation due to springback. High-precision processing is usually carried out with CNC bending machines, and反弹补偿 software is used to improve forming accuracy.



Welding is an indispensable part of titanium alloy sheet metal processing. Due to the fact that titanium is highly reactive with oxygen, nitrogen, and hydrogen in the air at high temperatures, welding must be carried out under inert gas protection, with commonly used methods including tungsten inert gas welding (TIG) and electron beam welding (EBW) to ensure weld quality and maintain the biological safety of the material.



Finally, surface treatment is particularly important for medical titanium alloy. Common surface treatment processes include sandblasting, acid washing, anodic oxidation, and plasma spraying, which can not only improve the corrosion resistance and biocompatibility of the parts, but also enhance their bonding ability with human tissues.



In summary, the processing of medical titanium alloy sheet metal is a highly technical and strict process. It not only requires advanced equipment and professional process support, but also requires a deep understanding of material properties. With the continuous growth of demand for high-quality implants and medical devices in the medical industry, further optimization of titanium alloy sheet metal processing technology will be an important direction for promoting the development of the medical device industry.
