The machining center was developed from a CNC milling machine. The biggest difference with the CNC milling machine is that the machining center has the ability to automatically exchange processing tools, and by installing tools for different purposes on the tool magazine, the processing tools on the spindle can be changed through the automatic tool changer in a clamping to achieve a variety of processing functions.
CNC machining center is a high-efficiency automatic machine tool composed of mechanical equipment and CNC system, which is suitable for processing complex parts. CNC machining centers are one of the world's highest-yielding and most widely used CNC machine tools. Its comprehensive processing capacity is strong, the workpiece can complete more processing content after a clamping, the processing accuracy is higher, the batch workpiece of medium processing difficulty, its efficiency is 5~10 times that of ordinary equipment, especially it can complete many ordinary equipment can not complete the processing, the shape is more complex, the precision requirements of single piece processing or small and medium-sized batch multi-variety production is more applicable. It integrates the functions of milling, boring, drilling, tapping and cutting threads on one machine, so that it has a variety of processing process means. Machining centers are classified according to the spatial position of the spindle during machining: horizontal and vertical machining centers. According to the process use, it is classified as: boring and milling machining center, composite machining center. According to the special classification of functions: single table, double table and multi-table machining center. Machining centers for single-axis, double-axis, three-axis and exchangeable headstock applications. According to the classification of guide rails: linear rail machining center, hard rail machining center machine, etc.
