1.The machining center is equipped with a tool magazine and can automatically change the tool to perform multi-process processing on the workpiece. 2. After the workpiece is clamped once, the CNC system can control the machine tool to automatically select and replace the tool according to different processes, automatically change the machine tool spindle speed, feed rate, and the trajectory of the tool relative to the workpiece, as well as other auxiliary functions. 3. Modern machining centers enable the workpiece to achieve continuous, efficient, and high-precision machining of multiple surfaces, multiple features, and multiple stations after one clamping, that is, process concentration, which is the most prominent feature of the machining center.45 ° sawing, 90 sawing can be arbitrary choose
