1. A large number of parts of workflow, complicated parts of machining do not require complex workflow. If you change the shape and size of the parts, you only need to modify the part processing program, which is suitable for the development and modification of new products.

2. The quality of processing is stable, the processing accuracy is high, and the accuracy of repeated accuracy is high.

3. Multi -varieties and small batches of production efficiency are high, which can reduce the time for production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the better cutting amount.

4. The complex surface that is difficult to process for processing is difficult to process, and can even be processed to process some irreplaceable processing parts.

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