CNC machining of aerospace parts refers to the use of computer numerical control technology to carry out precision milling, turning and other machining of metal or composite material blanks specially used in the aerospace field to produce parts that meet extremely stringent standards. This type of accessories is not only "processed", but also "carved". They are widely used in key parts such as aircraft skeletons, rocket engines, and avionics systems, and involve typical products such as casings, bladders, and actuators.
