■ 通端止端沒有檢查用和加工用的區(qū)別 以前的JIS測(cè)量方式在量規(guī)的止端有檢查用和加工用的區(qū)別，ISO測(cè)量方式則沒有，凡事在規(guī)格要求之內(nèi)無論是何種形式的螺紋（在允許磨損的 范圍之內(nèi))，顯示符合的話該產(chǎn)品則為合格。 Go and NOT GO of the ISO gauge system is made with same dimentions for both inspection and working. ■ 作為外螺紋的外用量規(guī)，滿足了以前的卡規(guī)和新的環(huán)規(guī)的功能。 The ISO system adds a ring gauge for male thread (out side diameter) inspection. ■ 判定螺紋環(huán)規(guī)的合格與否 以前的JIS測(cè)量方式的螺紋環(huán)規(guī)，嵌合點(diǎn)檢量規(guī)螺紋被嵌合不能輕易松動(dòng)則判定產(chǎn)品為合格。ISO測(cè)量方式的螺紋環(huán)規(guī)是根據(jù)通止兩端的點(diǎn)檢用 塞規(guī)通規(guī)來檢查的。通規(guī)的點(diǎn)檢用塞規(guī)通規(guī)（GRGF）可以輕松穿過，止規(guī)的點(diǎn)檢用塞規(guī)（GRNF)擰進(jìn)不超過一圈就被卡住的話就判定為合格 的。止規(guī)的點(diǎn)檢用塞規(guī)（GRGF,NRNF)的判斷方法同通規(guī)。 The inspection method for ring thread gauges is different from the conventional JIS system.Under the conventional system,acceptance is given when the inspection gauge fits perfectly.In the ISO-based system,acceptance is given when the GO inspection plug(GRGF) passes through the GO thread ring gauge (GR) and the stop inspection plug (GRNF) cannot be turned more than one and a half turns from either side of the screw.Inspection plugs (NRGF) (NRNF) are used similarly for NOT GO ring gauges (NR). ■ 磨損點(diǎn)檢用塞規(guī) 磨損點(diǎn)檢用塞規(guī)的止端是考慮到量規(guī)壽命的增大和螺紋產(chǎn)品合格率的減少這一情況而適當(dāng)規(guī)定，它沒有被JIS化而是新的ISO規(guī)定的產(chǎn)品被導(dǎo)入 JIS系統(tǒng)中。 The conventional JIS gauge inspection specifies the use of a worn inspection plug to check GO thread ring gauges only.The ISO-based system specifies its use for NOT GO thread ring gauges as well. |
