CNC Turning It is to point to a kind of craft method that carries on the spare parts processing on numerical control machine tool, numerical control machine tool machining and the craft regulation that traditional machine tool machining are said to be consistent on the whole, but also produced apparent change. A machining method that USES digital information to control the displacement of parts and tools. It is an effective way to solve the problems of various parts, small batch, complex shape and high precision, and realize high efficiency and automatic machining.cnc machining metal parts CNC machining (nc) refers to machining with nc tools. CNC index-controlled machine tools are programmed by CNC machining language, usually code G. CNC machining G code language tells CNC machine tool machining tool to use what kind of cartesian position coordinates, and control the feed speed of the tool and spindle speed, as well as tool converter, coolant and other functions. CNC machining has great advantages over manual machining, such as CNC machining parts are very accurate and repeatable; CNC machining can produce parts with complex shapes that cannot be finished by hand.CNC machining technology has been widely promoted, most machining workshops have CNC machining capacity, the typical machining workshop in the most common CNC machining methods are CNC milling, CNC car and CNC EDM line cutting (EDM line cutting). The tool for CNC milling is called CNC milling machine or CNC machining center. The lathe which carries on the numerical control turning processing is called the numerical control turning center. CNC machining G code can be manually programmed, but usually the machining workshop with CAM (computer-aided manufacturing) software automatically read CAD (computer-aided design) files and generate G code program, CNC machine control.
