CNC machining has the following advantages:

(1) greatly reduce the number of tooling, processing complex shape parts do not need complex tooling. If you want to change the shape and size of the parts, you only need to modify the parts processing procedure, which is suitable for the development and modification of new products.

(2) stable processing quality, high processing accuracy, high repetition accuracy, to meet the requirements of aircraft processing.

(3) multiple varieties, small batch production of higher production efficiency, can reduce the production preparation, machine tool adjustment and process inspection time, but also because of the use of optimal cutting and cutting time.

(4) can process conventional methods difficult to process complex surface, even some processing parts can not be observed.

The disadvantage of CNC machining is the high cost of machine tools, requiring maintenance personnel with a higher level.
