Machining centers are developed from CNC milling machines. One difference from CNC milling machines is that the machining center has the ability to automatically exchange machining tools. By installing tools for different purposes on the tool magazine, the machining tools on the spindle can be changed through the automatic tool changer in one clamping. processing function.

CNC machining center is a high-efficiency automatic machine tool composed of mechanical equipment and CNC system, which is suitable for processing various complex parts. The CNC machining center is one of the CNC machine tools with high output and wide application. Its comprehensive processing ability is strong, the workpiece can complete more processing content after one clamping, and the processing accuracy is high. For batch workpieces with moderate processing difficulty, its efficiency is 5 to 10 times that of ordinary equipment, especially it can complete The processing that many ordinary equipment cannot complete is more suitable for single-piece processing or medium and small batch multi-variety production with complex shapes and high precision requirements.

It concentrates the functions of milling, boring, drilling, tapping and thread cutting on one device, so that it has a variety of processing methods. The machining center is equipped with a tool magazine, which stores various tools or inspection tools in different quantities, which are automatically selected and replaced by the program during the processing. This is the main difference between it and CNC milling machine and CNC boring machine. Especially for workpieces that must use tooling and special equipment to ensure product quality and efficiency. This will save a lot of time and cost for the development and modification of new products, so that enterprises have strong competitiveness.

Machining centers are classified according to the spatial position of the spindle during machining: horizontal and vertical machining centers. According to the process and use, there are: boring and milling machining center, compound machining center. According to the special classification of functions, there are: single worktable, double worktable and multi worktable machining center. Machining centers with single, double, triple and interchangeable headstocks. According to the classification of guide rails: line rail machining center, hard rail machining center, etc.
