Problems in machining titanium alloy fasteners

December 09, 2021

1.1 Mechanical processing machine operation and production problems

In the production and processing process of titanium alloy fasteners, the processing requirements for workshop are higher. In lathe processing, the density of titanium alloy fasteners is relatively higher than other materials, and the technical requirements for processing and processing difficulty will be higher. The machining process of the technical requirements for production factory has certain processing problems, in the process of machining, for cutting knife wear degree will be more serious, need to find a higher quality alloy tool to carry on the processing production technology, can reduce the cost, it is titanium alloy fasteners in machining process of a significant problems, Need to carry on the reasonable plan adjustment and the processing technological flow, the processing condition improvement.

1.2 Corrosion of titanium alloy fasteners during processing and preservation

Titanium alloy fasteners in the process of mechanical processing and production, because the fastener installation of mechanical parts is not so high, it is easy to produce a certain gap, so that there will be surface coating flow between the metal gap, resulting in fasteners in the production process is prone to corrosion. During subsequent use, connection tightness will be affected. Titanium alloy materials are relatively high corrosion resistance, because there is oxygen in the air. The titanium alloy material oxidizes with oxygen and forms a protective film on the surface. This film can effectively protect the titanium alloy inside the material from oxidation, thus improving the corrosion resistance of titanium alloy material. But in titanium alloy fasteners is the actual machining process, because the environment is constantly changing, including the ambient temperature, humidity and machining process of the equipment in the oxidation and so on factors, will lead to the titanium alloy fasteners is easy to corrosion occurs, it is titanium alloy fasteners prone to one of the problems in the middle of the production process.

1.3 Precision of mechanical processing of titanium alloy fasteners

In the production and processing of titanium alloy and candied fruit, the precision of machinery will be higher. In mechanical production, because the tool is in the working wear state every time in the production process, and according to the program to calibrate, titanium alloy fastener density is higher, the tool is vulnerable to wear in the processing process, in the wear state, the tool is still processed in accordance with the program, It is easy to cause the precision of tight parts in the process of processing is affected. If the precision of the fasteners in the whole process of precision is not strictly controlled in the range of error, in the process of use will not be able to close connection of titanium alloy and other materials, which have certain influence to the back of the use and improve precision of machining titanium alloy fasteners in the production process is the production process of a big problem that needs to be overcome. The fastener process product is the product made in the high precision production shop, this product has the better connection performance.
