What is the CNC

CNC is the abbreviation of English "Computer Numerical Control", translated into Chinese is: Computer Numerical Control, commonly known as "Numerical Control", in the Pearl River Delta area, people called "Computer gong". By the computer digital control of automatic machine tools, that is to say, as long as the computer digital control of automatic machine tools can be called CNC, including CNC lathes, machining centers, CNC laser cutting machine, CNC linear cutting, CNC punch and so on. A lot of people think CNC is CNC machining center, in fact, this kind of statement is not quite accurate.

CNC machining is an advanced machining technology in today's machinery manufacturing. It is an automatic machining method with high efficiency, high precision and high flexibility. It is to process the workpiece nc program input to the machine tool, the machine tool in the control of these data automatically processed in line with people's will of the workpiece.

Numerical control processing relative to manual processing has a great advantage, such as numerical control processing produced parts are very accurate and repeatable; Numerical control processing can produce manual processing can not be completed with complex shape parts, with numerical control processing can easily achieve multi-axis processing, such as surface processing, if you leave the NUMERICAL control processing, with ordinary machine tool to process, is almost impossible to complete. In addition, NC machining can easily implement flexible manufacturing systems.

Through the cutting tool will be blank processing into semi-finished product parts of the three axis CNC machine tools, called CNC milling or CNC machining center. The difference between the two is that there is no automatic tool change device.
