摘　　要：在车床上对小孔径攻螺纹时,大多数情况下使用丝锥和丝锥架进行手动攻螺纹,但是这种工艺往往收不到预期的精度和同轴度要求。在此提出一种可以提供小孔径攻螺纹工装在进行此类加工工艺时能够显著提高精度要求和同轴度要求。此工装可以实现小孔径类工件的攻内螺纹的要求,并且能很好地保证螺纹的精度要求和表面粗糙度要求。The traditional manual processing does not get the expected accuracy and alignment requirements.This experiment suggests a new processing technology of using small aperture tapping screw tooling to significantly improve the precision and alignment requirements.This equipment can realize small aperture class artifacts of tapping the requirement of internal thread, and ensure the accuracy of screw thread and surface roughness requirements.
