[0002] A vertical machining center is a highly automated, multifunctional CNC machine tool equipped with a tool magazine and automatic tool changer. After the workpiece is clamped once on the machining center, the digital control system can control the machine tool according to different processes, automatically selecting and changing tools, automatically changing the machine tool's spindle speed, feed rate, and the tool's relative motion trajectory relative to the workpiece, and other auxiliary functions, to complete multiple processes on several surfaces of the workpiece in sequence. It also has a variety of tool changing or tool selection functions, greatly improving production efficiency. During mechanical processing of the workpiece, it is necessary to use a fixture to fix the workpiece.
