What are the advantages and disadvantages of CNC machining?

1. Advantages: 　　①, reducing the number of tooling: 　　 greatly reducing the number of tooling, processing parts with complex shapes does not require complicated tooling. 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, stable processing quality: 　　 high processing precision, high repeatability, suitable for the processing requirements of aircraft.　　③. Multi-variety, small batch: 　　The production efficiency is higher in the case of small batch production, which can reduce the time of production preparation, machine tool adjustment and process inspection, and the cutting time is reduced due to the use of the best cutting amount.　　④, processing section: 　　 can process complex profiles that are difficult to process by conventional methods, and even process some unobservable processing parts.　　2. Disadvantages: 　　The disadvantage is that the processing equipment is relatively expensive, and the requirements for the quality of the operators are relatively high.
