Vim li cas ho tsis kawm txog calibration thiab calibration ntawm txheej thickness gauges!
1. Zero calibration
Lub xoom calibration yog ua rau ntawm cov hlau substrate (uncoated substrate) ntawm cov khoom no.
1. Xaiv lub xoom-hloov lub rooj tsavxwm, uas yog cov hlau tsis muaj hlau substrate (vim qhov sib txawv ntawm qhov sib txawv ntawm qhov chaw ua haujlwm, tom qab xoom-hloov kho, rov ntsuas dua yuav tsis yog qhov xoom kiag li, uas yog qhov tshwm sim ib txwm muaj);
2. Nyob rau sab ntawv qhia zaub mov interface, xaiv Calibration, ces Zero Calibration, ces nias lub sojntsuam vertically thiab nrees rau lub substrate, thiab lub xoom calibration yuav ua tau txiav;
3. Rov ua cov kauj ruam 1 thiab 2 saum toj no kom tau txais qhov tseeb dua xoom taw tes thiab txhim kho kev ntsuas qhov tseeb.
2. Multi-point calibration
Calibration yog ua los ntawm cov ntawv txheeb. Qhov no calibration txoj kev yog haum rau high-precision ntsuas thiab me me workpieces, hardened steel, thiab alloy steel.
1. Calibrate lub zero point ua ntej;
2. Tom qab ntawd ua ib qho kev ntsuas ntawm ib daim ntawv txheem uas nws thickness yog kwv yees li ntawm qhov kwv yees thickness ntawm cov txheej yuav tsum tau kuaj, thiab ces kho cov kev nyeem ntawv kom nws ncav cuag tus qauv tus nqi;
3. Npog nrog ntau daim ntawv txheej txheem, ntsuas, thiab tom qab ntawd kho cov kev nyeem ntawv ua kom nws ncav cuag tus nqi tus qauv.
Cov ntawv tuab tuab yog cov txheej txheem tuab siv los txheeb xyuas qhov ua yuam kev thiab qhov hloov pauv ntawm EPK txheej thickness gauge lossis los ntsuas cov txheej thickness gauge. Lub calibration tej yam kev mob ntawm lub txheej thickness gauge yog raws li nram no: qhov kub thiab txias nyob rau hauv lub chav kuaj pom yog 20 ± 2 degree; lub sij hawm ntsuas kub ntawm cov ntawv tuab thiab ntsuas ntsuas yog 2 teev; Cov av noo hauv chav kuaj pom tsawg dua lossis sib npaug li 65 feem pua; lub sij hawm preheating rau ntsug optical meter tsis tsawg tshaj li 15 feeb; Lub zog hluav taws xob rau qhov ntsuas yog 220 (1 ± 10%) V, 50Hz.
Cov kev cai tshwj xeeb yog raws li hauv qab no:
1. Kev tshwm sim
Yuav tsum tsis muaj qhov tsis xws luag xws li khawb thiab pob ntawm ob qho tib si ntawm daim ntawv tuab. Txoj kev calibration yog kev soj ntsuam pom.
2. thaj chaw muaj txiaj ntsig
Qhov cheeb tsam ntawm lub voj voog nrog lub vojvoog ntau dua 5 hli yuav tsum tau cim rau qhov chaw tsis sib xws, thiab thaj tsam ntawm qhov sib txawv ntawm qhov tuab tuab yuav tsum tsis pub tsawg dua 20mm × 20mm. Txoj kev calibration yog ntsuas nrog tus pas ntsuas steel.
3. Qhov nruab nrab ntawm tus lej
Siv peb qhov sib npaug gauge blocks thiab ntsug optical gauge los ntsuas qhov tuab ntawm cov qauv thickness ntawv los ntawm txoj kev ncaj nraim los yog txoj kev sib piv. Ua ntej kev ntsuas, siv cov roj av aviation los ntxuav lub ntsuas ntsuas, daim ntawv tuab, ntsuas qhov muag, ntsuas qhov ntsuas, thiab lub thickness ntawm lub ntsuas lub hau siv rau calibration. Lub vojvoog ntawm curvature tsis tsawg dua 20mm. Thaum ntsuas tus pas ntsuas qis, lub ntsuas lub hau yuav tsum maj mam hu nrog cov ntawv tuab tuab los ntawm kev tig ceg kom tiv thaiv kev cuam tshuam ntawm daim ntawv thickness. Cov ntsiab lus calibration yog 5 cov ntsiab lus sib npaug sib npaug hauv thaj chaw zoo (nrog rau qhov chaw nruab nrab), rau cov ntawv tuab tuab uas tsis muaj cov cim hauv cheeb tsam zoo, thaj chaw zoo yuav tsum nyob rau hauv ib lub voj voog nrog qhov nruab nrab ntawm qhov nruab nrab thiab ib lub vojvoog tsis pub tsawg tshaj 10 hli. .
4. Uniformity yuam kev
Standard thickness daim ntawv uniformity yuam kev. Txoj kev calibration yuav siv sij hawm qhov sib txawv siab tshaj plaws ntawm cov thickness nyeem ntawm txhua qhov taw tes thiab qhov nruab nrab thickness raws li qhov tsis sib xws ntawm cov qauv thickness ntawv, thiab nws cov nqi yuav tsum tsis pub tshaj qhov yuav tsum tau muaj.
