Turning, grinding and milling combined machining numerical control machine tool

The invention provides a turning, grinding and milling combined machining numerical control machine tool in the technical field of machine tool machining. The cutter part is arranged above the working bed; the moving part is used for driving the working bed to move back and forth along the lower part of the cutter part in a reciprocating manner; the device is characterized by further comprising radial locking parts, and a plurality of radial locking parts which are pressed and locked on the surface of a workpiece in the circumferential direction are symmetrically arranged on the two sides of the working bed. The device has the advantages of being particularly suitable for accurate searching, positioning and drilling of the center of the end, locking of the center hole and the like when the long-rod-shaped workpiece is turned, ground and milled. 本发明提供了机床加工技术领域中的一种车磨铣复合加工数控机床，包括：工作床；设于所述工作床上方的刀具部；以及用于驱动所述工作床沿所述刀具部下方来回往复移动的移动部；其特征在于，还包括：径向锁定部，沿周向压持、锁定在工件表面的若干组所述径向锁定部对称设于所述工作床的两侧。本发明特别适用于长杆状工件车磨铣加工时端部中心的精准查找、定位钻孔
