为了使外径千分尺和内径千分尺测量尺寸方法统一,笔者制作了两种具有一定测量力的内径千分尺测量头和弓架量表0~10mm。它是除去外径千分尺弓架,保留了测微螺杆、固定套管、微分筒、测力装置(或者直接采用量具厂的微分头装置),最好是带硬质合金面的。并将测量面磨成
In order to make OD micrometer and ID micrometer size measurement method of unity, I made a certain amount of measurement of the inner diameter micrometer head and bow gage scale 0 ~ 10mm. It is to remove the outer diameter of the micrometer bow stand, retaining the micrometer screw, fixed casing, differential cylinder, force measuring device (or directly using the gage factory differential head device), preferably with carbide surface. And the measurement surface ground into
