CNC machining usually refers to computer digital control precision machining, which is a new type of machining technology. The main work is to compile machining programs, that is, to convert the original manual work to computer programming. Of course, you need to have experience in manual processing.

General CNC machining usually refers to precision machining, CNC machining lathes, CNC machining milling machines, CNC machining boring and milling machines, etc. 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 program, which is suitable for new product development and modification.

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

3. The 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.

Fourth, it can process complex surfaces that are difficult to process by conventional methods, and even process some unobservable processing parts. The disadvantage of CNC machining is that the cost of machine tool equipment is expensive and requires a high level of maintenance personnel.
