In fact, numerical control milling machine, in Guangzhou, Jiangsu, Zhejiang and Shanghai area someone called "CNC machining center", is a kind of automatic machine tool equipped with program control system. Numerical control machine tool is the abbreviation of Computer numerical control machine tool, is a kind of automatic machine tool controlled by program. The control system can logically process the program with control code or other symbolic instructions, and decode it through the computer, so as to make the machine tool action and processing parts. The blank is processed into semi-finished parts by cutting tools.

CNC Machining refers to Machining with CNC tools. CNC exponential control machine tools are controlled by NUMERICAL control language programming, usually G code. Numerical control machining G code language tells the numerical control machine tool to use what kind of cartesian position coordinates, and control the tool feed speed and spindle speed, as well as tool converter, coolant and other functions. Numerical control processing relative to manual processing has a great advantage, such as numerical control processing produced parts are very accurate and repeatable; CNC machining can produce parts with complex shapes that cannot be completed by manual machining. Numerical control machining technology has been widely promoted, most machining workshops have numerical control machining capacity, the most common numerical control machining methods in typical machining workshops are numerical control milling, numerical control car and NUMERICAL control EDM wire cutting (electric spark wire cutting). CNC milling tools are called CNC milling machines or CNC machining centers. CNC turning machining lathes are called CNC turning centers. Numerical control machining G code can be manually programmed, but usually machining shop with CAM (computer aided manufacturing) software automatically read CAD (computer aided design) files and generate G code program, control of numerical control machine tools.

Dongguan Lifei Precision Machinery mould Co., LTDCNC processing has the following advantages:

① Greatly reduce the number of tooling, processing of complex shape parts do not need complex tooling. If you want to change the shape and size of parts, only need to modify parts processing procedures, suitable for new product development and modification.

② Stable processing quality, high processing accuracy, high repetition accuracy, to meet the requirements of aircraft processing.

③High production efficiency in a multi-variety, low-volume production reduces the time required for production preparation, machine tool adjustment and process inspection, and reduces the cutting time due to the use of optimal cutting quantities.

④It can process complex surface which is difficult to be processed by conventional methods, and even some parts which cannot be observed.

The disadvantage of CNC machining is that the cost of machine tools and equipment is expensive, and maintenance personnel are required to have a higher level.
