Rau cov yeeb yaj kiab nkhaus (tsis yog tiaj tus), yuav ua li cas xaiv cov txheej txheej thickness gauge
Thaum cov neeg siv xaiv cov txheej thickness gauge, ntxiv rau kev xaiv cov kev ntsuas sib txawv, ntsuas qhov ntau thiab qhov tseeb raws li cov substrates sib txawv, lawv kuj yuav tsum xav txog qhov chaw ntawm cov khoom ntsuas raws li qhov tseeb. Tshwj xeeb tshaj yog rau cov khoom uas tsis yog-planar, feem ntau thickness gauges nyob rau hauv tsev thiab txawv teb chaws muaj cov kev cai meej ntawm lub vojvoog ntawm curvature. Txij li thaum qee cov neeg siv tsis meej pem txog qhov no, peb tau tsim daim duab kos duab los piav qhia yuav ua li cas xaiv cov txheej tuab tuab rau ntsuas qhov tsis sib xws xws li cov kav hlau.
Qhov tseem ceeb yog saib lub vojvoog ntawm curvature ntawm cov khoom raug ntsuas (nws pom zoo kom koj tshawb fawb ntawm Baidu txog dab tsi lub vojvoog ntawm curvature yog, yog li kuv yuav tsis mus rau hauv cov ntsiab lus ntawm no)
Rau kev nkag siab yooj yim, Northern thiab yav qab teb tides tau piav qhia siv lub voj voog. Rau cov khoom xws li ovals, lub vojvoog ntawm lub voj voog inscribed nws tus kheej yog txaus.
Noj cov duab ntawm sab laug ua piv txwv, qhov tsawg kawg nkaus ntawm qhov nkhaus ntawm lub vojvoog yog: convex 1.5mm, concave 25mm
Uas yog hais tias, yog hais tias nws yog los ntsuas lub sab nrauv phab ntsa, qhov tsawg tshaj plaws yeeb nkab haum uas lub ntsuas yuav ntsuas yog ib tug yeeb nkab nrog ib tug vojvoog ntawm tsis tsawg tshaj li 1.5 hli; Yog hais tias nws yog los ntsuas cov phab ntsa sab hauv, lub vojvoog ntawm cov khoom ntsuas yuav tsum tsis pub tsawg tshaj 25 hli.
Feem ntau hais lus, cov txheej txheej nkhaus uas tuaj yeem ntsuas tau los ntawm R1 kuj tseem siv tau rau cov txheej txheej nkhaus ntawm R2. Ntawm qhov tsis sib xws, cov txheej txheej nkhaus uas tuaj yeem ntsuas tau los ntawm R2 yuav tsis siv rau cov txheej txheem ntawm cov khoom me me R1 los ntsuas.
Lub vojvoog saum npoo ntawm cov txheej txheej thickness ntsuas feem ntau muaj feem xyuam rau cov qauv sojntsuam thiab cov txheej thickness ntsuas nws tus kheej. Rau kev ntsuas ntawm sab hauv phab ntsa pleev xim zaj duab xis, "kab-hom" txheej thickness gauge feem ntau yog siv, thaum rau sab nrauv phab ntsa xim zaj duab xis, ob qho tib si siv tau.
Tus kws sau ntawv qhia tias txawm hais tias tus nqi ntawm ib lub thickness gauge yuav kim dua, nws tsim nyog rau ntau qhov chaw. Yog tias cov peev nyiaj txaus, nws tseem pom zoo kom yuav ib lub xov tooj ntawm lub thickness gauge.
