What is CNC Machining?

 CNC machining refers to the machining with special tools of CNC machine tools. CNC machine tools are programmed and manipulated by CNC machining language, generally G code. The NC G code language tells the NC machine tool which Cartesian coordinates to use for machining the NC blade and controls the feed rate of the NC blade and the rotating speed ratio of the spindle bearing, and its special tool converter, coolant and other functions. Relativity of NC machining Manual machining has great advantages, for example, the parts manufactured by NC machining are very accurate and accurate; Numerical control machining can produce and manufacture parts with a complicated design that cannot be processed manually. The technology of NC machining has been widely popularized, and most machining workshops have the ability of NC machining. The most common NC machining methods in typical machining workshops are NC machining center, NC machining center and EDM wire cutting (spark discharge wire cutting) of NC machine tools. The special tool for developing a CNC machining center is called a CNC milling machine or CNC machining center. The CNC lathe that carries out milling with CNC machine tools is called the CNC lathe center. NC machining G code can be programmed by manual service, but in general machining workshops, CAM (Aided Design and Manufacturing) mobile phone software is used to automatically load CAD (Aided Design and Design Scheme) documents and convert them into G code program flow to operate NC machine tools.

CNC machining has the following advantages:

(1) The number of tooling is greatly reduced, and complicated tooling is not needed to process parts with complicated shapes. If you want to change the shape and size of parts, you only need to modify the parts processing program, which is suitable for new product development and modification.

② The machining quality is stable, the machining accuracy is high, and the repetition accuracy is high, which meets the machining requirements of aircraft.

③ In the case of multi-variety and small batch production, the production efficiency is higher, which can reduce the time of production preparation, machine tool adjustment and process inspection, and the cutting time is reduced due to the use of the best cutting quantity.

(4) It can be used to machine complex profiles that are difficult to be machined by conventional methods, and even to machine some parts that cannot be observed.

The disadvantage of NC machining is the high cost of machine tools and equipment, which requires maintenance personnel to have a high level.
