The process we use for measuring external thread length is as follows:
% e+ {2 P; R& R- u$ R$ [2 M$ W
, B9 q: B' |6 M; W# `; E9 D! p1. Measure the pitch diameter for the entire length of the threaded component with a ring gauge to ensure it is within spec. ...

外螺紋是很容易測(cè)準(zhǔn)確的,關(guān)鍵是在于內(nèi)螺紋,,我們也遇到這個(gè)問(wèn)題,,要求螺紋深度公差0.1,用螺紋塞規(guī)測(cè)是需要減去前面半個(gè)不完整牙,。但這也達(dá)不到測(cè)量精度,,我們也還在繼續(xù)思考中,。加退刀槽是不到腦筋的,,能加還不早加了。 |
