General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining boring and milling machine, etc.

CNC machining services have 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 parts, you only need to modify the part processing program, which is suitable for new product development and modification.
②The processing quality is stable, the processing accuracy is high, and the repeat accuracy is high, which is suitable for the processing requirements of aircraft.
③The production efficiency is higher in the case of multi-variety 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 amount.
④It can process complex profiles that are difficult to process by conventional methods, and even process some unobservable processing precision CNC machined components.
The disadvantage of CNC machining is that the cost of machine tools is expensive and requires a high level of maintenance personnel.
