With the deepening of military-civilian integration, there are more and more private enterprises in the field of aerospace parts processing. Some produce aerospace parts processing fixtures, and some produce aerospace precision parts. So what issues should be paid attention to in the processing of aerospace precision parts?

At present, it involves engine discs, landing gear, shafts, structural links, etc. After the successful development and flight test of C919, the development of aerospace manufacturing industry has been accelerated. In today's global manufacturing integration, quality and cost competition is extremely fierce, and more and more Many enterprises are faced with problems such as improving efficiency and reducing costs of aerospace components.

In order to improve efficiency, many aerospace parts processing enterprises start with tools. The common aerospace parts processing tools on the market include titanium alloy special tools, PCD tools, special chip breaking tools and so on. Different tool materials are also different, for example , The bar alloy tool is characterized by corrosion resistance and high temperature resistance. PCD tools have the characteristics of high hardness, high compressive strength, good thermal conductivity and wear resistance. The tools selected for aviation precision parts processing must have the above characteristics, otherwise the tool life Short, the efficiency cannot be improved.

The processing structure of aerospace parts generally has the characteristics of thin wall, easy deformation, and difficult processing. Therefore, during processing, attention should be paid to the non-interference between the workpiece clamping and the optimization of the processing route. Semi-finishing is carried out in the way of finishing to ensure the size of the workpiece.

At present, a number of enterprises engaged in the processing of aerospace precision parts have developed mature processing techniques and discuss with each other regularly. This is to bring some high-end and advanced technologies to more aerospace parts processing enterprises.
