测微丝杆位移平稳性是标准规定的测微量具工作质量的性能之一。但是,到目前为止,还是依靠检查员的手的一种主观方法来评定平稳性。这就不可能对丝杆整个运动范围的位移平稳性作出准确地评价,因为丝杆的不连续转动不超过180°的范围。采用主观检查法是由于标准中对位移平稳性没有具体规定,仅仅指出 Micrometer screw displacement stability is the standard provisions of the micrometer work quality performance. However, to date, a subjective approach that relied on the inspector’s hand was to assess the stationarity. This makes it impossible to accurately evaluate the displacement smoothness of the entire range of movement of the screw as the discontinuous rotation of the screw does not exceed the range of 180 °. The use of subjective inspection method is due to the standard does not have a specific regulation of the displacement stability, just pointed out
