加工中心即“自动换刀数控机床”,刀具更换及工件转位都由计算机数字控制,使工件在一次装夹后,多种工序可以顺序加工直至完成。其加工精度、生产率比普通机床高得多,劳动力强度低,虽然设备费用较昂贵,但节省了许多其它方面的费用、因此仍获得良 Machining center that is "automatic tool change CNC machine tools, tool change and workpiece indexing by the computer numerical control, so that the workpiece in a fixture, a variety of processes can be processed in sequence until completed. Its machining accuracy, productivity is much higher than the average machine, labor intensity is low, although the cost of equipment is more expensive, but save many other costs, so still get good
