Mu dziko la kupanga molondola komanso kuwongolera khalidwe, lingaliro la "chowonadi" limagwirizana ndi kulondola kwa zida zanu zoyezera. Pamaziko enieni a dongosololi la kulondola pali granite surface plate. Nthawi zambiri amatchedwa "master" wa shopu yamakina kapena labotale yowunikira, granite surface plate imapereka malo ofunikira owunikira omwe miyeso ina yonse imayerekezeredwa. Popanda maziko okhazikika, athyathyathya, komanso odalirika, kuwerengera zida zapamwamba kumakhala kosatheka, ndipo mtundu wa zida zopangidwa umakhala nkhani yongoganizira.
Nkhaniyi ikufotokoza za kufunika kwa ma granite pamwamba pa mbale poonetsetsa kuti ma granite ndi olondola, makhalidwe enieni omwe amawapanga kukhala muyezo wa makampani, komanso njira zabwino kwambiri zosungira chida chofunikirachi.
Maziko a Metrology: Chifukwa Chiyani Granite?
Zisanafike pakati pa zaka za m'ma 1900, chitsulo chopangidwa ndi chitsulo chinali chinthu chofala kwambiri chomwe chimagwiritsidwa ntchito popanga ma plates apamwamba. Komabe, makampaniwa asintha kwambiri kukhala granite, makamaka granite wakuda wapamwamba kwambiri, pazifukwa zingapo zomveka zomwe zimachokera ku sayansi ya sayansi ndi zinthu zakuthupi.
1. Kuchepetsa Kukhazikika ndi Kupsinjika Maganizo:
Granite ndi chinthu chachilengedwe chomwe chapangidwa kwa zaka mamiliyoni ambiri. Pofika nthawi yomwe chimakumbidwa, kupsinjika kwamkati komwe nthawi zambiri kumakhudza zitsulo zotayidwa kwatha kalekale. Kuchepetsa kupsinjika kwachilengedwe kumeneku kumatanthauza kuti mbale ya granite yopangidwa bwino sidzapindika kapena kupotoka pakapita nthawi, zomwe zimapangitsa kuti ikhale yokhazikika.

2. Kuchuluka kwa Kutentha kwa Kutentha:
Poyesa molondola, kutentha ndiye gwero lalikulu la zolakwika. Zitsulo zimakula ndikuchepa ndi kusinthasintha kwa kutentha, zomwe zimatha kusintha kusalala kwa mbale pamwamba. Granite ili ndi coefficient yotsika kwambiri ya kutentha poyerekeza ndi chitsulo kapena chitsulo. Izi zikutanthauza kuti ngakhale kutentha kwa malo mu labotale kusinthasintha, mbale ya granite imakhalabe yokhazikika, kuonetsetsa kuti miyezo imakhala yofanana tsiku lonse.

3. Kuchepetsa Kugwedezeka:
Granite ili ndi mphamvu zabwino kwambiri zochepetsera chinyezi—pafupifupi kuwirikiza ka 10 kuposa chitsulo. Imayamwa kugwedezeka kuchokera ku malo ozungulira (monga makina apafupi kapena kuyenda kwa mapazi), zomwe zimawaletsa kusokoneza njira yoyezera yomwe imachitika pamwamba.

4. Kulimba ndi Kukana Kuvala:
Ndi kuuma kwa Mohs pafupifupi 7, granite imapirira kwambiri kukanda ndi kuwonongeka. Mosiyana ndi mbale zachitsulo, zomwe zimatha kupanga ma burrs kapena m'mbali zokwezedwa zikagundidwa, granite imakonda kusweka kapena kuuma ikawonongeka. Izi ndizofunikira kwambiri kuti pakhale kulondola kwa calibration chifukwa burr yokwezedwa pa mbale yachitsulo imatha kunyamula gawo ndikuyambitsa muyeso wolakwika, pomwe chip kakang'ono mu mbale ya granite nthawi zambiri sichimakhudza kusalala kozungulira.

Kumvetsetsa Magiredi a Calibration
Kuti muwonetsetse kuti ma calcification ndi olondola, munthu ayenera kusankha mtundu woyenera wa plate pamwamba pa plate kuti agwiritsidwe ntchito mwanjira inayake. Si ma granite plate onse omwe amapangidwa mofanana; amagawidwa m'magulu malinga ndi kulekerera kwawo kusalala, nthawi zambiri amayesedwa mu ma millilion a inchi imodzi kapena ma microns.
- Giredi AA (kapena Giredi 000): Iyi ndi giredi yolondola kwambiri, yomwe nthawi zambiri imagwiritsidwa ntchito ngati chidziwitso chachikulu mu ma laboratories oyesera. Imagwiritsidwa ntchito kuwona kulondola kwa ma plate ena pamwamba kapena ma gauge olondola kwambiri.
- Giredi A (kapena Giredi 00): Giredi iyi ndi yoyenera zipinda zogwiritsira ntchito zida zolondola kwambiri komanso madipatimenti owunikira. Nthawi zambiri imagwiritsidwa ntchito poyang'ana mawonekedwe a zida zolondola komanso kukonza zida zamanja.
- Giredi B (kapena Giredi 0): Iyi ndi giredi yokhazikika ya workshop, yomwe imagwiritsidwa ntchito pa ntchito yokonza zinthu, kukonza makina, ndikuwunika magawo omwe kulondola kwambiri sikofunikira.
Kusankha giredi yoyenera ndi gawo loyamba poonetsetsa kuti unyolo wanu woyezera ndi wovomerezeka. Mwachitsanzo, kugwiritsa ntchito mbale yoyezera workshop kuti muyezere micrometer yolondola kwambiri, kungabweretse zolakwika zomwe zingasokoneze ntchito yonse yopangira.
Njira ndi Miyezo Yoyezera
Kusunga kulondola kwa kuwerengera kumafuna kutsatira miyezo yokhwima, monga ASME B89.3.7 kapena DIN 876. Miyezo iyi imafotokoza kusiyana kovomerezeka kwa kusalala kutengera kukula kwa mbale ndi mtundu wake.
Kulinganiza sikungokhudza kuyang'ana pakati pa mbaleyo; kumaphatikizapo kusanthula kwathunthu kwa pamwamba ponse. Akatswiri nthawi zambiri amagwiritsa ntchito "njira yozungulira" kapena kusanthula kwamagetsi kuti awonetse malo a mbaleyo. Njirayi imazindikira malo aliwonse "apamwamba" kapena "otsika" omwe angakhale atayamba chifukwa cha kuwonongeka kapena kukhazikika.
Pakupanga zinthu zamakono, komwe kuli kocheperako, kuchuluka kwa ma calibration ndikofunikiranso. Mbale yomwe imagwiritsidwa ntchito kwambiri popanga ingafunike kukonzedwanso miyezi 6 mpaka 12 iliyonse, pomwe mbale yayikulu yomwe ili pamalo olamulidwa ingafunike kuyang'aniridwa zaka ziwiri kapena zitatu zilizonse.
Kusamalira: Kusunga Choonadi
Ngakhale mbale yabwino kwambiri ya granite pamwamba pake idzataya kulondola kwake ngati siisamalidwa bwino. Mbali ya pamwamba pake ndi chida chogwirira ntchito, osati benchi logwirira ntchito, ndipo kuisamalira koteroko ndikofunikira kuti ikhale ndi moyo wautali.
1. Ukhondo:
Musanayesedwe, pamwamba pake payenera kutsukidwa. Fumbi, mafuta, ndi zitsulo zimatha kugwira ntchito ngati zopatulira, kukweza gawo lomwe likuyesedwa ndikuyambitsa zolakwika zazikulu. Kupukuta kosavuta ndi nsalu yoyera ndi chosungunulira chofewa nthawi zambiri kumakhala kokwanira.

2. Kuphimba:
Ngati sikugwiritsidwa ntchito, mbaleyo iyenera kuphimbidwa ndi matabwa kapena pulasitiki yoteteza. Izi zimateteza pamwamba pa nyumbayo ku kuwonongeka mwangozi, fumbi, ndi kuwala kwa dzuwa, zomwe zingayambitse kutentha kosayenera.

3. Kuzungulira:
Kuvala sikofanana kawirikawiri. Mu workshop, ogwiritsa ntchito nthawi zambiri amagwiritsa ntchito pakati pa mbale kuposa m'mbali. Kuti mbaleyo ikhale yolimba komanso kuti ikhale yolondola, ndi bwino kuzunguliza mbaleyo madigiri 180 nthawi ndi nthawi (ngati siimakhazikika nthawi zonse), kuonetsetsa kuti kuvulalako kumagawidwa mofanana pamwamba pake.

4. Pewani Kudzaza Zinthu Mopitirira Muyeso:
Ngakhale granite ndi yolimba, ndi yopyapyala. Kugwetsa chogwirira ntchito cholemera pa mbale kungayambitse chip kapena ming'alu. Kuphatikiza apo, kuchirikiza mbale pamakona ake kokha kungayambitse kugwedezeka pansi pa katundu wolemera. Kuchirikiza koyenera, nthawi zambiri pogwiritsa ntchito njira yoyikira ya mfundo zitatu, kumaonetsetsa kuti mbaleyo ikhalebe yathyathyathya pansi pa katundu.

Mapeto
Pofuna kupanga zinthu zabwino kwambiri, granite pamwamba pake imakhalabe ngwazi yosayamikirika. Ndiwo mtetezi wachete wa khalidwe, kupereka maziko olimba komanso athyathyathya omwe kulondola konse kumadalira. Mwa kumvetsetsa momwe granite imagwirira ntchito, kusankha giredi yoyenera, komanso kutsatira ndondomeko yolondola komanso yokonza, opanga amatha kuwonetsetsa kuti muyeso wawo ndi wolondola, ziwalo zawo zimasinthasintha, ndipo mbiri yawo ya khalidwe imakhalabe yolondola. M'dziko lovuta kwambiri, granite yosavuta imakhalabe muyezo womaliza wa choonadi.
