在生产中常遇到带有台阶内孔的加工零件,其大孔径的尺寸精度要求较高,如图(a)的(?)51.1_0~(0.016)和图(b)的(?)73.5_0~(0.018)内径尺寸。本文介绍一种检测方法,简述如下。
In the production often encountered with the step hole with the processing of parts, the larger the size of the large aperture precision requirements, such as (a) (51.1_0 ~ (0.016) and Figure (b) (73.5_0 ~ (0.018) diameter size. This article describes a detection method, summarized as follows.
