In the machining and production process, titanium alloy fasteners are widely used. In the process of use, the weight of the machine itself can be reduced. This is a lightweight material, especially in the aerospace field. With the development of science and technology in recent years, the use of titanium alloy fasteners has continued to expand, which can closely connect titanium alloys with other materials, which is of great significance for machining and production.

 

Titanium alloy fasteners have problems in machining

 

1.1 Production problems of mechanical processing machines

 

In the production and processing process of titanium alloy fasteners, the processing requirements of the workshop are higher. In the processing of lathes, the density of titanium alloy fasteners is relatively higher than other materials, and the technical requirements and processing difficulties for processing will be higher. The technical requirements in these processing processes have certain processing difficulties for the production factory. During the processing, the wear degree of the cutting tool will be more serious. It is necessary to find a higher quality alloy tool to be able to carry out the processing and production process. In order to reduce costs, this is a significant problem in the machining and production of titanium alloy fasteners, and it is necessary to carry out reasonable adjustment of the plan and improvement of the processing process and processing conditions.

 

1.2 Processing and preservation corrosion problems of titanium alloy fasteners

 

In the process of machining titanium alloy fasteners, because the tightness of the mechanical parts is not so high when the fasteners are installed, it is easy to generate a certain gap, so that there will be a surface between the metal gaps. Paint flows in, making fasteners susceptible to corrosion during production. In the subsequent use process, the connection tightness will be affected. The reason why titanium alloy materials have high corrosion resistance is because of the presence of oxygen in the air. A protective film is formed on the surface of the titanium alloy material after the oxidation reaction with oxygen. This layer of film can effectively protect the titanium alloy inside the material from being oxidized, thereby improving the corrosion resistance of the titanium alloy material. However, in the actual machining process of titanium alloy fasteners, due to the constant changes in the environment, including the influence of factors such as the temperature of the surrounding environment, humidity, and the oxidation of equipment during processing, it will lead to titanium alloy fasteners. Corrosion is easy to occur, which is one of the problems that are prone to occur in the production process of titanium alloy fasteners.

 

1.3 Precision problems of machining titanium alloy fasteners

In the production and processing of titanium alloys and candied fruit, the precision requirements for machinery will be higher. In mechanical production, because the tool is in a state of wear and tear during each production process, and it is calibrated according to the program, the density of titanium alloy fasteners is higher, and the tool is easily worn during the machining process. Under the state, the tool is still processed according to the program, it is easy to cause the precision of the compact parts to be affected during the processing. If the precision of the fasteners is not strictly controlled within the error range during the entire processing process, the titanium alloy and other materials cannot be tightly connected during the use process, which will have a certain impact on the subsequent use. The precision of titanium alloy fasteners in the machining production process is a major problem that needs to be overcome in the production process. For example, the fastener process product shown in Figure 1 is a product made in a high-precision production workshop, and this product has better connection performance.
