CNC horizontal boring and milling machine is a automatic tool change device and arbitrary indexing of digital control machine tool nc rotary table, After a clamping workpiece can automatically complete several profiles of a variety of machining process. CNC horizontal boring and milling machine tool storage manipulator lifting mechanism by the Liquid motive, The ball screw vice, Reduction ear, Friction plate electromagnetic clutch, etc. Understanding of knife library manipulator lifting mechanism performance requirements ,The understanding of the principle of operation of knife library manipulator lifting mechanism, Structure design and calculation analysis, Liquid motivation drives the ball screw rotation, lead frame hand movement, By slowing down and clutch and screw brake, make hand aircraft parked in knife position accurately, Good design can bring about quick replac
