4 Cov ntsiab lus ntawm Kev Siv Txheej Txheej Thickness Gauge kom raug
1. Vim li cas cov txheej thickness gauges uas tau dhau los ntawm kev txheeb xyuas ntawm Lub Tsev Haujlwm Saib Xyuas Kev Ntsuas thiab Kev Ntsuas muaj qhov sib txawv loj ntawm cov ntaub ntawv ntsuas thaum siv tiag?
Qhov no kuj yog ib qho teeb meem uas nquag ntsib. Feem ntau, muaj ob hom ntawm cov neeg muas zaub uas yuav thickness gauges. Ib qho yog qhov nthuav dav ntawm kev tsim khoom thiab qhov yuav tsum tau ua kom muaj cov thickness gauges. Lwm qhov yog cov khoom xav tau thiab cov khoom siv tshiab txheej txheej thickness gauge. Qhov xwm txheej uas peb tau ntsib yog feem ntau yog rau thawj hom ntawm cov neeg siv khoom, vim tias cov khoom siv tshiab thickness gauge thiab cov thickness gauge yav dhau los tsis tas yuav yog tib tus qauv,
Qhov teeb meem no tshwm sim vim hais tias lub hauv paus taw tes xaiv rau calibration ntawm txheej thickness gauge ua ntej ntsuas yog txawv los ntawm cov calibration txheem daim ntawv. Txhawm rau kom tswj tau qhov sib xws, cov txheej thickness ntsuas yuav tsum siv tib lub calibrated xoom point substrate rau xoom point calibration, thiab kuj siv tib tus qauv yas zaj duab xis rau calibrate thiab calibrate rau tib calibration substrate, thiaj li hais tias cov ntaub ntawv ntsuas ntawm txheej thickness. gauge yuav koom ua ke.
2. Vim li cas cov ntaub ntawv ntsuas los ntawm cov txheej thickness gauge ntawv pov thawj los ntawm National Institute of Metrology thiab Testing tseem tsis raug siv tiag tiag?
Feem ntau hais lus, cov neeg siv khoom xav tias nws tau lees paub los ntawm lub xeev. Feem ntau, lub sijhawm siv tau yog ib xyoos. Nws yeej tsis muaj teeb meem siv nws li ntawm xyoo no. Qhov tseeb, hauv kev siv tiag tiag, calibration yuav tsum tau ua ua ntej txhua qhov kev siv. Yog tias koj tsis ua qhov no, qhov ntsuas ntsuas yuav muaj qhov yuam kev {{0}} feem pua. 0 microns, nws yog qhov pom tseeb tias qhov ntsuas yuav hnov qhov tsis raug, yog li nws yuav tsum tau ntsuas ua ntej txhua qhov kev siv. Peb pom zoo tias qhov kev ntsuam xyuas lub voj voog ntawm txheej txheej thickness ntsuas feem ntau yog ib xyoos.
3. Cov txheej thickness gauge yog calibrated ua ntej txhua yam siv, tab sis cov ntaub ntawv ntsuas tseem tsis raug?
Qhov teeb meem no tshwm sim heev. Feem ntau hais lus, cov neeg siv khoom siv random calibration substrate ntawm lub thickness gauge rau calibrate. Nyob rau hauv txoj kev no, lub substrate ntawm tus neeg siv khoom tus kheej cov khoom yuav tsum tau raws nraim tib yam li cov khoom ntawm random substrate. Qhov teeb meem no yeej tsis yooj yim sua. Nov yog qhov peb xav hais ntxiv. Cov neeg siv khoom yuav tsum xaiv tib yam tsis muaj coated (los yog plated) workpiece raws li cov khoom ntsuas rau xoom calibration, thiab ces calibrate nws nrog ib tug calibration nplhaib thiab yas zaj duab xis, thiaj li hais tias cov ntaub ntawv ntsuas yog txhim khu kev qha. Nco ntsoov siv lub calibration matrix nrog tib cov duab (curvature), tib yam khoom, thiab tib roughness rau xoom point calibration.
4. Puas yog daim ntawv pov thawj txheej thickness gauge kom tsis muaj teeb meem hauv kev siv tiag tiag?
Thaum txheeb xyuas cov txheej thickness gauge, feem ntau hais lus, tus neeg soj ntsuam muaj cov txheej txheem calibration los txheeb xyuas cov txheej thickness gauge. Cov txheej thickness ntsuas yog tsim nyog thiab tus pas ntsuas kub infrared tau ntawv pov thawj.
