CNC又叫做电脑锣、CNCCH或数控机床其实是香港那边的一种叫法，后来传入大陆珠三角，其实就是数控铣床，在广、江浙沪一带有人叫"CNC加工中心"

一般CNC加工通常是指精密机械加工、CNC加工车床、CNC加工铣床、CNC加工镗铣床等

CNC优点

①大量减少工装数量，加工形状复杂的零件不需要复杂的工装。如要改变零件的形状和尺寸，只需要修改零件加工程序，适用于新产品研制和改型。

②加工质量稳定，加工精度高，重复精度高，适应飞行器的加工要求。

③多品种、小批量生产情况下生产效率较高，能减少生产准备、机床调整和工序检验的时间，而且由于使用比较佳切削量而减少了切削时间。

④可加工常规方法难于加工的复杂型面，甚至能加工一些无法观测的加工部位。

CNC, also known as computer gongs, CNCCH, or CNC machine tools, is actually a kind of method in Hong Kong. Later it was introduced into the Pearl River Delta on the mainland. In fact, it is a CNC milling machine. Some people in Guangzhou, Jiangsu, Zhejiang, and Shanghai are called "CNC processing centers."
CNC machining usually refers to precision machining, CNC machining lathe, CNC processing milling machine, CNC processing boring milling machine, etc..
CNC advantages
The quantity of workmanship is greatly reduced, and the processing of complex shapes does not require complex workmanship. If you want to change the shape and size of the parts, you only need to modify the parts processing program and apply it to new product development and modification.
2 The processing quality is stable, the processing precision is high, the repetition precision is high, adapts the processing requirement of the aircraft.
3 Production efficiency is higher in multi-variety and small batch production, which can reduce production preparation, machine tool adjustment and process inspection time, and reduce cutting time due to the use of optimal cutting quantity.
4 The complex surface that can be processed by conventional methods is difficult to process, and even some unobservable processing parts can be processed.
