In the one-piece CNC machining, auxiliary time (non-chip time) account for a large proportion. To further enhance the productivity of the machine, it must be taken to promote maximum compression auxiliary time. There are already a lot of use of multi-spindle CNC machine, multi-turret, as well as automatic tool changer with magazine so as to reduce tool change time. For the chip to increase the amount of CNC machine tools, bed institutions must facilitate chip evacuation.
CNC machine tool main drive motion refers to the production of chips drive movement, for example, CNC lathe workpiece spindle drive rotary motion, vertical machining center spindle driven milling, boring and grinding wheel rotation. CNC machine tool main drive movement is through the main drive motor drag.
