What are the application prospects and development trends of Dongguan turning and milling composite processing technology

In recent years, Dongguan turning and milling composite processing technology has been applied in aviation manufacturing enterprises such as aircraft, aviation engine and accessory factories in China. The equipment types are mainly concentrated in the turning and milling composite series products of WFL Company in Austria and the milling and milling composite processing center of Baume Company in Switzerland. However, due to the short practical application time, there is a general lack of mature processing techniques, programming methods, and post-processing techniques that are suitable for the characteristics of product processes and equipment processes.

Therefore, the currently introduced turning and milling processing equipment is basically at a relatively low operating level.

The main problems faced in the manufacturing process of aviation products are prominent in long process routes, complex processes, low processing efficiency, severe processing deformation, and high processing costs. There is a very broad development space.

For example, the milling process of the overall framework of an aircraft fuselage usually involves preparation of blanks/blanks, benchmark processing, rough machining of internal shapes, rough machining types, precision machining benchmarks, semi precision machining, and precision machining of internal shapes, semi precision machining. Dozens of processes, such as precision machining, precision forming, hole processing, fitter trimming, and testing, can only be completed through multiple flipping and clamping. At present, the machining of integral bladed discs in the field of aviation engines also uses integral forging blanks, which can be completed through dozens of processes such as turning and milling, milling, polishing, surface treatment and strengthening, inspection and testing.

The manufacturing cycle of these parts is often long, usually hundreds of hours, and requires the use of multiple different types of CNC machines and a large number of fixtures, tools, measuring tools, etc. during the processing process. In addition, the repeated replacement of mounting cards not only causes long waiting times for parts during the manufacturing process, affecting the production cycle, but also accumulates mounting errors, affecting the dimensional accuracy of the parts.
