摘　　要：在汽车覆盖件模具加工中,螺钉孔加工是否合格是镶块能否完成整体互换的重要因素。改善互换镶块的螺钉孔加工工艺,采用新的加工方法可以有效提高螺钉孔位置精度。本文探讨了一种提高互换镶块螺钉孔加工精度的新工艺,通过数控机床配合U钻加工来提高互换镶块螺钉孔加工精度。In the automobile covering parts mold processing,whether the screw hole processing is qualified or not is rather important for inserts overall exchange. Improving the screw hole machining process of interchangeable inserts,and adopting new machining method can effectively improve the screw hole position accuracy. This paper discusses a new technology to improve the machining accuracy of screw holes in interchangeable inserts,with which machining accuracy of screw holes in interchangeable inserts can be improved by CNC machining with U drilling.
