CNC is also called computer gong, CNCC or CNC machine tool is actually a name on the other side of Hong Kong, and then it was introduced into the mainland Pearl River Delta, in fact, it is a CNC milling machine, in Guangzhou, Jiangsu, Zhejiang and Shanghai, some people called "CNC machining center ".

General CNC machining usually refers to precision machining, CNC machining lathes, CNC machining milling machines, CNC machining boring and milling machines, etc

CNC machining has the following advantages:

① The number of tooling is greatly reduced, and complex tooling is not required for processing complex shaped parts. If you want to change the shape and size of the parts, you only need to modify the parts processing program, which is suitable for new product

development and modification.

②The processing quality is stable, the processing accuracy is high, the repetition accuracy is high.

③In 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 the cutting time is reduced by using the optimal cutting amount.

④It can process complex surfaces that are difficult to be processed by conventional methods, and can even process some unobservable processing parts.

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