CNC machining has the following advantages

① The number of tooling is greatly reduced, and complex tooling is not required for processing parts with complex shapes. If you want to change the shape and size of the part, you only need to modify the part processing procedure, which is applicable to the development and modification of new products.

② The processing quality is stable, the processing accuracy is high, and the repetition accuracy is high, which is suitable for the processing requirements of aircraft.

③ The production efficiency is high in the case of multiple varieties and small batch production, which can reduce the time of production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of the best cutting quantity.

④ It can process complex surfaces that are difficult to be processed by conventional methods, and even some processing parts that cannot be observed.

The disadvantage of CNC machining is that the machine tool equipment is expensive, and the maintenance personnel are required to have a high level.
