Machining centers are developed from CNC milling machines. The biggest difference from the CNC milling machine is that the machining center has the ability to automatically exchange machining tools. By installing different-purpose tools on the tool magazine, the machining tool on the spindle can be changed through an automatic tool changer in one clamping to achieve a variety of machining function.

             CNC machining center is a high-efficiency automatic machine tool suitable for processing complex parts composed of mechanical equipment and numerical control system. CNC machining centers are among the most productive and widely used CNC machine tools in the world. Its comprehensive processing ability is strong, and the workpiece can complete more processing content after one clamping, and the processing accuracy is high. For batch workpieces with medium processing difficulty, its efficiency is 5 to 10 times that of ordinary equipment, especially it can complete The processing that cannot be completed by ordinary equipment is more suitable for single-piece processing with complex shapes and high precision requirements or small and medium-sized batches of multiple varieties. It concentrates the functions of milling, boring, drilling, tapping and thread cutting on one device, so that it has a variety of processing methods.

              Machining centers are classified according to the spatial position of the spindle during machining: horizontal and vertical machining centers. According to the classification of technological purposes: boring and milling machining center, compound machining center. There are special classifications by function: single worktable, double workbench and multi-workbench machining centers. Single-axis, double-axis, three-axis and machining centers with interchangeable headstocks. According to the classification of guide rails, there are: line rail machining centers, hard rail machining centers, etc.
