[0002] A vertical machining center is a highly automated multi-functional numerical control machine tool with a tool magazine and an automatic tool changer. After a workpiece is clamped on the machining center once, the digital control system can control the machine tool to automatically select and change tools according to different processes, automatically change the spindle speed, feed rate of the machine tool, the movement track of the tool relative to the workpiece and other auxiliary functions, and sequentially complete the machining of multiple processes on several surfaces of the workpiece. And it has a variety of tool changing or tool selection functions, thus greatly improving the production efficiency. When the workpiece is being machined, it needs to be fixed on the machine tool workbench by a fixture, and most of them are T-slot flat plates.
