What does cnc mean?

Cnc refers to computer numerical control.

Computer numerical control, also known as numerical control, is a method of controlling mechanical movement and machining process with digital information. The NC machine tool automatically processes the machined parts according to the pre-programmed processing program. Its functions include coordinate axis control, tool offset compensation, programming function, parallel operation, tool management and control, electronic contact alignment and so on.

Advantages of CNC-

(1) The number of tooling is greatly reduced, and complicated tooling is not needed to process parts with complicated shapes. If you want to change the shape and size of parts, you only need to modify the processing program of parts, which is suitable for new product development and modification.

(2) The machining quality is stable, the machining accuracy is high, and the repeatability is high, which meets the machining requirements of aircraft.

(3) In the case of multi-variety and small batch production, the production efficiency is higher, which can reduce the time of production preparation, machine tool adjustment and process inspection, and reduce the cutting time because of the use of the best cutting parameters.
