CNC machining can greatly reduce the number of tooling, machining complex shape parts do not need complex tooling. If you want to change the shape and size of a part, just modify the part processing procedure, this applies to the development and modification of new products. CNC processing quality stability, high processing accuracy, high repetition accuracy, in many varieties, small batch production conditions, CNC processing has a higher production efficiency, can reduce production preparation, machine tool adjustment, and process inspection time, and because of the use of good, cutting amount and reduce cutting time. So what are the application areas involved in CNC machining?
