CNC is also called computer gong, CNCCH or CNC machine tool. It is actually a name from Hong Kong. Later it was introduced to the Pearl River Delta in mainland China. It is actually a CNC milling machine. In Guangdong, Jiangsu, Zhejiang and Shanghai, people call it "CNC machining center".
General CNC processing usually refers to precision machining, CNC processing lathes, CNC processing milling machines, CNC processing boring and milling machines, etc.
.
CNC Machining refers to processing using CNC machining tools. CNC index controlled machine tools are programmed and controlled by a CNC machining language, usually G code. The CNC machining G code language tells the CNC machine tool what Cartesian position coordinates are used for the processing tool, and controls the tool's feed speed and spindle speed, as well as tool changer, coolant and other functions.
CNC machining has great advantages over manual machining. For example, the parts produced by CNC machining are very accurate and repeatable; CNC machining can produce parts with complex shapes that cannot be completed by manual machining.
