Momwe Mungasungire Kulinganiza Kwanthawi Yaitali kwa Zigawo Zanu Zolondola za Granite

Mu nkhani ya uinjiniya wolondola ndi metrology, zigawo zolondola za granite—monga ma plates pamwamba, maziko a makina, ndi matebulo owunikira—zimalemekezedwa chifukwa cha kukhazikika kwawo kwapadera, kuuma, komanso kukana dzimbiri. Gawo la granite labwino kwambiri, likasamalidwa bwino, limatha kusunga kulinganiza kwake ndi kusalala kwake kwa zaka zambiri, kukhala maziko osagwedezeka a miyeso yanu yofunika kwambiri. Komabe, ngakhale granite yolimba kwambiri siili yotetezeka ku zisonkhezero zazing'ono za chilengedwe chake ndi kagwiritsidwe ntchito kake. Kusunga kulinganiza kwa nthawi yayitali sikochitika kamodzi kokha; ndi njira yopitilira yomwe imafuna kumvetsetsa kwakukulu kwa kayendetsedwe ka chilengedwe, kusamalira mosamala, komanso njira yosamalira mosamala.
Kudziwa bwino za Environmental Foundation
Mdani wamkulu wa kulinganiza kwa nthawi yayitali si kuwonongeka kwa tsiku ndi tsiku, koma malo osalamulirika. Kuti muwonetsetse kuti zigawo zanu za granite zikusunga kulondola kwawo kwa micron, choyamba muyenera kukhazikitsa maziko olimba.
Kutentha ndiye chinthu chofunikira kwambiri. Granite ili ndi kuchuluka kochepa kwambiri kwa kutentha, koma si zero. Kuti zinthu zikhale zolondola kwambiri, zigawo ziyenera kusungidwa mu labotale yoyezera kutentha, makamaka 20°C (±2°C). Kutentha kwadzidzidzi kapena kuwonetsedwa mwachindunji ndi dzuwa, ma ventilator a mpweya woziziritsa, ndi ma ducts otenthetsera kungayambitse kutentha kwa malo. Kutsika kumeneku kumabweretsa kupsinjika kwamkati mkati mwa mwalawo, zomwe zimapangitsa kuti pakhale kusintha kwakanthawi koma kofunikira komwe kumawononga kulondola kwa muyeso. Kuphatikiza apo, zida zazikulu zogwirira ntchito kapena ma gauge blocks ziyenera kuloledwa kuti zigwirizane ndi pamwamba pa granite kwa maola angapo musanayambe kuyeza kuti kutentha kusasunthike.
Chofunikanso ndi maziko oyikapo. Gawo la granite limakhala lokhazikika ngati momwe limakhalira. Liyenera kuyikidwa pa maziko olimba komanso opanda kugwedezeka. Mu malo olondola kwambiri, nthawi zambiri izi zikutanthauza kugwiritsa ntchito ma pad odzipatula othamanga kapena opumira kuti achotse granite ku kugwedezeka kwa pansi komwe kumachitika chifukwa cha makina apafupi, ma forklift, kapena ngakhale kuyenda kwa mapazi. Mukayika mbale yayikulu pamwamba, chithandizo choyenera sichingakambiranedwe. Chiyenera kukhala pa dongosolo lothandizira la mfundo zitatu kapena zisanu (nthawi zambiri mfundo zazikulu zitatu zomwe zimapanga triangle ya isosceles ndi mfundo ziwiri zothandizira). Kapangidwe kameneka kamaletsa kupsinjika kwamkati ndi "kugwedezeka," kuonetsetsa kuti mbaleyo yakhazikika bwino, yopanda kupsinjika. Pambuyo poyimilira koyamba, tikulimbikitsidwa kwambiri kuti gawolo likhale losasunthika kwa maola 12 mpaka 24 kuti kupsinjika kulikonse kotsala kuthe musanawerengere ziwerengero zomaliza za calibration.
Kusamalira Tsiku ndi Tsiku ndi Njira Zabwino Zogwirira Ntchito
Chilengedwe chikayang'aniridwa, nthawi yayitali yowunikira granite yanu imadalira kwambiri momwe imachitidwira ntchito tsiku ndi tsiku. Pamwamba pa mbale ya granite ndiye chuma chake chamtengo wapatali kwambiri, ndipo kuteteza ku kuwonongeka kwakuthupi ndikofunikira kwambiri.
Nthawi zonse onetsetsani kuti pamwamba pa granite ndi paukhondo musanagwiritse ntchito komanso mutagwiritsa ntchito. Fumbi, zitsulo, ndi tinthu tating'onoting'ono tomwe timayambitsa kukwawa pamwamba. Gwiritsani ntchito nsalu yofewa, yopanda utoto wothira pang'ono ndi chotsukira cha pH kapena mowa woyeretsedwa kwambiri kuti mupukute pamwamba. Pewani mankhwala osungunula kapena mankhwala a alkaline, chifukwa amatha kuwononga pang'onopang'ono pamwamba pa mwalawo pakapita nthawi. Mukayika zinthu zogwirira ntchito pa mbale, musamazigwedeze kapena kuzikoka. M'malo mwake, zinyamuleni ndikuziyika pansi pang'onopang'ono. Pazinthu zolemera, gwiritsani ntchito ma jacks kapena ma hoist osinthika kuti mugawire kulemera mofanana ndikupewa katundu wambiri womwe ungayambitse kupsinjika kapena kusweka kwa malo.

Ndikofunikanso kukumbukira zomwe granite surface plate si. Si malo ogwirira ntchito, anvil, kapena cholowa m'malo mwa zida zina. Musagwiritse ntchito pamwamba polemba, kuponya, kapena ngati maziko a ntchito zolemera zamakina zomwe zingayambitse kuwonongeka. Kuphatikiza apo, maginito workpieces ayenera kuchotsedwa maginito asanayikidwe pa mbaleyo. Magneticism yotsalira imatha kukoka tinthu tating'onoting'ono tachitsulo kuchokera mumlengalenga, zomwe zimatha kugwira ntchito ngati chopopera pansi pa gawo loyenda, ndikukanda pang'ono pamwamba pake molondola.
Kukonza Mogwira Mtima ndi Kukonzanso Nthawi ndi Nthawi
Ngakhale mutayang'anira bwino chilengedwe komanso kusamalira bwino, kuwunikira kwa nthawi yayitali kumafuna nthawi yokonza bwino. Granite ndi chinthu chachilengedwe, ndipo kwa zaka zambiri, imatha kusintha pang'ono chifukwa cha kugwedezeka kapena kukhazikika kwa zinthu. Chifukwa chake, kudalira kokha kuwunikira koyambirira kwa fakitale ndi chiopsezo chomwe sichiyenera kuchitika mu labotale yolondola.
Gwiritsani ntchito njira yowunikira magawo osiyanasiyana. Tsiku lililonse kapena sabata iliyonse, ogwira ntchito ayenera kuyang'ana mwachangu malo omwe awonongeka komanso kuyang'ana ngati ali osalala pogwiritsa ntchito mulingo wolondola wa mzimu kapena m'mphepete wowongoka. Izi zimathandiza kuthana ndi mavuto aliwonse omwe amabwera nthawi yomweyo kapena kusintha kwakukulu.
Kuti muyezetse bwino nthawi yayitali, konzani nthawi yokonzanso zinthu nthawi ndi nthawi, nthawi zambiri miyezi 6 mpaka 12 iliyonse, kutengera kuchuluka kwa momwe zinthu zimagwiritsidwira ntchito komanso kuchuluka kwa zinthu zomwe zimafunika kupirira. Njirayi iyenera kuchitidwa ndi akatswiri oyenerera a metrology pogwiritsa ntchito zida zotsatirika, monga zida zamagetsi zapamwamba kapena ma laser interferometers. Panthawiyi, pamwamba ponseponse pamakhala scan (nthawi zambiri mu gridi kapena "nyenyezi") kuti apange mapu okwanira a malo a mbaleyo. Ngati pali kusiyana pang'ono, akatswiri aluso nthawi zambiri amatha kuchita kukonza kapena kukanda pamalopo kuti abwezeretse pamwamba pa DIN kapena ISO tolerance grade yake yoyambirira.
Mwa kuwongolera chilengedwe mosamala, kukakamiza njira zoyendetsera zinthu motsatira malamulo, komanso kudzipereka ku ndondomeko yokonzanso zinthu mwaukadaulo, mukutsimikiza kuti zigawo zanu zolondola za granite zimakhalabe muyezo wodalirika. Kudzipereka kumeneku sikungoteteza ndalama zanu zokha komanso, chofunika kwambiri, kumatsimikizira umphumphu ndi kudalirika kwa muyeso uliwonse womwe gulu lanu limapanga.
