CNC machining refers to the method of machining parts on CNC machine tools. Generally speaking, the technological processes of CNC machining and traditional machine tool machining are consistent, but significant changes have also occurred. Machining method that uses digital information to control part and tool displacement. CNC machining is an effective way to solve the problems of multiple parts, small batches, complex shapes, and high precision, and to achieve efficient automatic processing.

CNC machining is a process in which the control system issues instructions to make the tool make various movements that meet the requirements. The technical requirements, such as the shape and size of the workpiece and the requirements of the CNC Parts Processing process, are expressed in the form of numbers and letters. The CNC processing quality is stable, the surface texture of the finished product is clear, the metal texture is firm, smooth and flat, without scratches and edges, and the resistance of the heat dissipation coefficient of the raw material is small, and it will not change with the CNC processing. CNC machining integrates milling, boring, drilling, tapping and thread cutting into one, making it equipped with a variety of processing methods. The machining center is equipped with a tool magazine, which stores various numbers of various tools or inspection tools, and is automatically selected and replaced by the program during the processing. CNC machining can automatically select and replace tools, automatically change auxiliary functions such as spindle speed, feed speed, and tool trajectory relative to the workpiece, and complete multiple processes in sequence on several surfaces of the workpiece, with a variety of tool changes Or tool selection function.

The concentration of the CNC machining process and automatic tool change reduces the time for workpiece clamping, measurement, and machine tool adjustment. At the same time, it also reduces the time for workpiece turnover, handling and storage between processes, shortens the production cycle, and has obvious economic benefits. The machining center is suitable for small and medium batch production with complex parts, high precision requirements and frequent product replacement.

In the case of multi-variety and small-batch production, the CNC machining quality is stable and the production efficiency is high. It can reduce the time for production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of the optimal cutting amount. It is difficult to process traditional methods. Machining complex profiles, and even machining parts that cannot be observed.
