① A large number of tooling is reduced, and complex tooling is not needed to process 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 the development and modification of new products.
② The machining quality is stable, the machining precision is high, and the repetition precision is high, which can meet the processing requirements of aircraft.
③ In the case of multi variety and small batch production, the production efficiency is higher, the time of production preparation, machine tool adjustment and process inspection can be reduced, and the cutting time is reduced due to the use of the best cutting amount.
④ It can machine complex surface which is difficult to process by conventional method, and even can process some parts which cannot be observed.
The advantages of CNC machine tools are as follows:
- Processing efficiency, saving processing time.
- Work intensity. After the workers have finished programming, they can go to drink tea after the first piece is qualified.
- Reduce the number of waste products. As long as the first piece is qualified, the processed parts will generally be qualified.
- High safety. The farther the worker is from the processing equipment, the more likely the accident will occur
