Cautions for aerospace parts processing

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 parts processing. So what issues should be paid attention to if you want to do aerospace parts processing ?

Aerospace parts processing currently involves such as engine discs, landing gears, shafts, structural connectors, etc. After the development and successful test flight of C919, it has accelerated the development of aerospace manufacturing industry. In today's global manufacturing integration, quality and cost competition are increased crazily, and more and more companies are facing issues such as improving efficiency and reducing costs in aerospace parts processing .

In order to improve efficiency, many aerospace parts processing companies start with tools. At present, the tools that we can commonly find in the market for aerospace parts processing include titanium alloy special tools, PCD tools, special chipbreaking tools, etc. Different tools  materials are also different. For example, titanium alloy tools are characterized by corrosion resistance and high temperature resistance; PCD tools are characterized by high hardness, high compressive strength, good thermal conductivity and wear resistance. The tool selected for aerospace parts processing must have the above-mentioned characteristics, otherwise the tool life will be short and efficiency will not be improved.

The processing structure of aerospace parts generally has the following characteristics, such as thin wall, easy deformation, difficult to process, etc., so in the processing, attention should be paid to the mutual interference of tools and fixtures, and the processing route is optimized. The processing technology should be carried out in a combination of rough and fine, first roughing and then semi-finishing, and fina finishing to ensure the size of the workpiece.

At present, many companies engaged in aerospace parts processing and tool companies have jointly formulated mature processing techniques, and also regularly discusses with each other to bring some high-end and advanced technologies to more aerospace parts processing companies.
