Machining Center), referred to as MC, is a high-efficiency automated machine tool composed of mechanical equipment and CNC systems used to process complex-shaped workpieces. The machining center is also called a computer gong. The machining center is equipped with a tool magazine and has an automatic tool changing function. It is a CNC machine tool that can perform multi-process processing after clamping the workpiece once. The machining center is a highly mechatronic product. After the workpiece is clamped, the CNC system can control the machine tool to automatically select and replace tools according to different processes, automatically set the tool, automatically change the spindle speed, feed amount, etc., and can continuously complete drilling, boring, Milling, reaming, tapping and other processes. Therefore, the workpiece clamping time, measurement and machine tool adjustment and other auxiliary process times are greatly reduced, and it has good economic effects for processing parts with complex shapes, high precision requirements, and frequent variety changes.
