CNC machining refers to the processing method of processing parts on CNC machine tools. In general, CNC machining and traditional machine tool processing processes are consistent, but there have been significant changes. A processing method for manipulating parts and tool displacements with digital information. CNC machining is an effective way to deal with many kinds of parts, small batch, cluttered shape, high precision and so on.
    CNC machining is the process by which the control system issues instructions that enable the tool to make various movements that meet the requirements, the shape and scale of the work pieces, and the technical requirements of the machining process are indicated in numbers and letters. CNC processing quality is stable, the finished product surface pattern is clear, the metal pattern is strong, smooth and flat, no scratches and angles, raw material heat dissipation coefficient resistance is small, will not be changed with CNC processing. Manufacturers are able to adjust specific processes to improve their cooling function. For example, oxidation, stretching, cooking, sand blasting and other processes can be carried out under CNC operation.
    CNC processing set milling, boring, drilling, tapping, cutting thread in one, so that it has a variety of processing techniques. The machining center has a knife library that stores different quantities of various tools or viewing tools and actively selects and replaces them by programs during machining. CNC machining can actively select and replace tools, actively change spindle speed, forward speed, tool relative to the moving track of the work piece and other auxiliary functions, and on several surfaces of the work piece to complete the processing of multiple operations, with a variety of tool replacement or tool selection functions.

The concentration of CNC machining process and active tool change reduces the time of workman parts loading, measuring and machine tool adjustment, so that the cutting time of the machine machine reaches about 80% of the machine tool start-up time (the general machine tool only 15 to 20%), together, it also reduces the turnover, transfer and storage time of the work pieces between processes, shortens the production cycle, and has obvious economic benefits. The machining center is suitable for small and medium-sized batch production with cluttered parts, high precision requirements and frequent product replacement.

In a variety of types, small batch production, CNC processing quality is stable, high yield efficiency, can reduce the production preparation, machine adjustment and process viewing moments, and because of the use of the best cutting volume and reduce cutting time, can be processed traditional methods difficult to process the messy profile, and even process some undying processing sites.
