Vertical Machining Center (Machining Center) is referred to as MC, which is a high-efficiency automatic machine tool composed of mechanical equipment and numerical control system for cnc machining complex-shaped workpieces. The processing center is also called the computer gong. The machining center is equipped with a tool magazine and has an automatic tool change function. It is a CNC machine tool that performs multi-process processing after clamping the workpiece once. The vertical machining center is a highly mechatronics product. After the workpiece is clamped, the CNC system can control the machine tool to automatically select and change tools according to different procedures, automatically set the tool, automatically change the spindle speed, feed, etc., and can continuously complete drilling, Various processes such as boring, milling, reaming, and tapping. Therefore, it greatly reduces the time of workpiece clamping, measurement and machine tool adjustment and other auxiliary procedures. The processing shape is more complicated, the precision is higher, and the parts with frequent replacement of varieties have good economic effects.

The vertical machining center is developed from the CNC milling machine. The same as the CNC milling machine, the vertical machining center is also composed of computer numerical control system (CNC), servo system, mechanical body, hydraulic system and other parts. But the machining center is not equivalent to the CNC milling machine. The big difference between the vertical machining center and the CNC milling machine is that the machining center has the function of automatically changing tools. By installing tools for different purposes in the tool magazine, it can be automatically changed in one clamping. The device changes the processing tools on the spindle to realize multiple processing functions such as drilling, boring, reaming, tapping, and grooving.

The CNC milling machine is a CNC milling machine that mainly uses milling methods to process parts. It can complete various complex processing such as planes, grooves, spiral grooves, forming surfaces, plane curves, and space curves.

The vertical machining center is mainly used for the processing of box and complex surface parts. It can concentrate the functions of milling, boring, drilling, thread processing and other functions on one equipment, because it has a variety of tool change or tool selection functions and Automatic workbench exchange device (APC), so the parts can automatically complete or nearly complete all the processing procedures on all sides of the part after one clamping, which greatly improves the production efficiency.
