The machining centre is a development from the CNC milling machine. The main difference with the CNC milling machine is that the machining centre has the ability to automatically exchange machining tools. By installing different tools for different purposes on the tool magazine, the machining tools on the spindle can be changed in one clamping by an automatic tool changer to achieve a variety of machining functions.
CNC machining centres are highly efficient automated machine tools for processing complex parts, consisting of mechanical equipment and CNC systems. The CNC machining centre is one of the most productive and widely used CNC machine tools in the world. Its comprehensive processing capacity is strong, the workpiece can be completed after a clamping more processing content, processing accuracy is high, on the medium processing difficulty of the batch workpiece, its efficiency is 5 to 10 times the ordinary equipment, especially it can complete many ordinary equipment can not complete the processing, the shape is more complex, high precision requirements of single processing or small and medium-lot multi-species production is more suitable. It concentrates the functions of milling, boring, drilling, tapping and cutting threads on a single machine, making it have a variety of processing process means. Machining centres are classified according to the spatial location of the spindle: horizontal and vertical machining centres. According to the process use classification: boring and milling machining centres, composite machining centres. According to the function of the special classification are: single table, double table and multi-table machining centre. Single-axis, dual-axis, three-axis and interchangeable spindle box machining centres. According to the classification of guide rails there are: line rail machining centres, hard rail machining centres machines, etc.
