笔者根据多年的实际工作经验和理论知识学习,结合实例,系统地分析了铝合金薄壁件盒体零件上的小直径相贯螺纹孔的传统加工方法中存在的效率低、废品率高的主要原因,总结出了在数控加工中心上高效攻丝的行之有效的方法,具有良好的推广性,为在数控加工中心上高效加工此类零件提供有价值的参考。 Based on years of practical work experience and theoretical knowledge, the author systematically analyzes the low efficiency and high rejection rate of the traditional processing methods of small diameter concentric screw holes on aluminum alloy thin-walled parts. Reason, summed up in the NC machining center efficient tapping effective method, has good promotion, in the NC machining center to provide efficient processing of such parts provide a valuable reference.
