Mu dziko losamala kwambiri la metrology ndi mainjiniya olondola, kulondola kwa maziko anu oyezera ndikofunikira kwambiri. Micrometer iliyonse ndi yofunika, ndipo chida chomwe chimayang'anira kupereka malo ofunikira osasinthika ndi granite surface plate. Kwa iwo omwe amagwira ntchito pamlingo wapamwamba kwambiri popanga, kuwerengera, ndi kuwongolera khalidwe, chisankho sichikungokhudza kusankha granite; ndi chokhudza kutsatira miyezo yapadziko lonse lapansi yofotokozedwa ndi tchati cha granite surface plate grade.
Kuyika chida choyezera pamalo osalala kumatsutsana ndi sayansi yovuta ya zinthu ndi uinjiniya zomwe zimagwiritsidwa ntchito popanga mbale yogwira ntchito bwino kwambiri. Makampani nthawi zambiri amazindikira magulu angapo olondola, nthawi zambiri amatsatira zofunikira zomwe zimakhazikitsidwa ndi miyezo monga Federal Specification GGG-P-463c (US) kapena DIN 876 (German). Kumvetsetsa dongosololi la magiredi ndikofunikira kwa woyang'anira aliyense wogula, katswiri wotsimikizira khalidwe, kapena injiniya wopanga mapulani.
Kusiyana Kofunika Kwambiri: Kumvetsetsa Granite Surface Table Grades
Tikamalankhula za tebulo la granite pamwamba pa kalasi 0 kapena mbale ya granite pamwamba pa kalasi A, tikutanthauza kusiyana kovomerezeka kuchokera ku kusalala kwangwiro m'dera lonse logwirira ntchito. Izi zimadziwika kuti kulekerera kusalala konse. Magirediwo amakhazikitsa dongosolo lolondola, logwirizana mwachindunji ndi ntchito zomwe zikuyenera bwino.

Giredi ya Laboratory (nthawi zambiri Giredi AA kapena Giredi 00): Izi zikuyimira kulondola kwakukulu. Ma plates mu giredi iyi ali ndi kulekerera kwakukulu ndipo nthawi zambiri amasungidwa kuti agwiritsidwe ntchito kwambiri, monga ma laboratories oyambira calibration komwe kuwongolera zachilengedwe kumakhala kokwanira ndipo miyeso yomwe yatengedwa imakhazikitsa muyezo kwa ena. Mtengo ndi kukonza mosamala komwe kumafunika kukuwonetsa kulondola kwawo kosayerekezeka.
-
Giredi Yoyendera (nthawi zambiri Giredi A kapena Giredi 0): Iyi ndi njira yogwirira ntchito m'madipatimenti ambiri owongolera khalidwe lapamwamba komanso zipinda zowunikira. Gome la granite pamwamba pa kalasi 0 limapereka kusalala kwapadera, zomwe zimapangitsa kuti likhale loyenera kuwunika kwambiri zigawo zolondola kwambiri komanso ma gauge oyezera, ma micrometer, ndi zida zina zoyezera. Kulekerera kwa giredi iyi nthawi zambiri kumakhala kawiri kuposa Giredi ya Laboratory, zomwe zimapangitsa kuti pakhale kulondola komanso kugwira ntchito bwino.
-
Giredi ya Chipinda cha Zida (nthawi zambiri Giredi B kapena Giredi 1): Giredi 1 ya granite pamwamba pa mbale mwina ndiyo giredi yodziwika bwino komanso yosinthasintha. Kulekerera kwake ndikoyenera kuwongolera khalidwe lonse, kuyang'ana pansi pa shopu, ndikugwiritsa ntchito popanga komwe kumafunikabe kulondola kwambiri, koma kulondola kwambiri kwa Giredi 0 ndi kopitirira muyeso. Imapereka malo ofunikira okhazikika ofunikira pakukhazikitsa zida, kukonza mapulani, ndikuchita macheke anthawi zonse pafupi ndi malo opangira makina.
-
Gulu la Sitolo Pansi (nthawi zambiri Giredi 2 kapena Giredi B): Ngakhale kuti ndi chida cholondola, giredi iyi idapangidwira kuyeza kosafunikira kwenikweni, nthawi zambiri imagwiritsidwa ntchito pa ntchito yokonza zinthu mozama kapena m'malo omwe kutentha kumakhala kosinthasintha kwambiri, ndipo kulondola kwapamwamba kwambiri sikuyenera kulamulidwa.
Chizindikiro chomwe chimasiyanitsa mbale ya granite ya giredi 1 ndi Giredi 0 ndi Kuwerenga Konse kwa Chizindikiro (TIR) kwa kusalala. Mwachitsanzo, mbale ya giredi 0 ya mainchesi 24 x 36 ingakhale ndi kusalala kwa mainchesi pafupifupi 0.000075, pomwe Giredi 1 yofanana kukula ingalole kulekerera mainchesi 0.000150. Kusiyana kumeneku, ngakhale kumayesedwa mu inchi imodzi, ndikofunikira kwambiri popanga zinthu zambiri.
Chifukwa Chiyani Granite? Ubwino wa Sayansi ya Zinthu
Kusankha zinthu sikosankha mwadala. Granite, makamaka granite wakuda (monga Diabase) yomwe nthawi zambiri imagwiritsidwa ntchito popanga mbale zabwino kwambiri, imasankhidwa pazifukwa zingapo zomveka zomwe zimapangitsa kuti ikhale yolimba kuposa njira zina zachitsulo:
-
Kukhazikika kwa Kutentha: Granite ili ndi coefficient yotsika kwambiri ya expansion ya kutentha (CTE). Mosiyana ndi chitsulo, chomwe chimakula ndikuchepa kwambiri ndi kusintha kwa kutentha, granite imasunga miyeso yake mosasinthasintha. Izi ndizofunikira kwambiri pamalo ogwirira ntchito pomwe kutentha sikumayendetsedwa bwino nthawi zambiri.
-
Kuchepetsa Kugwedezeka: Kapangidwe ka mchere wachilengedwe ka granite kamapereka mawonekedwe abwino kwambiri ochepetsera kugwedezeka kwamkati. Imatenga kugwedezeka kwa makina ndi kugwedezeka kwakunja bwino kuposa chitsulo, zomwe zimathandiza kuti makina oyezera azikhala okhazikika mwachangu ndikuwonetsetsa kuti kuwerenga kwake kuli kokhazikika.
-
Kulimba ndi Kukana Kuwonongeka: Granite ndi yolimba kwambiri, nthawi zambiri imakhala pakati pa 6 ndi 7 pa sikelo ya Mohs. Izi zimapangitsa kuti malo owonongeka azikhala olimba kwambiri komanso, chofunika kwambiri, kuwonongeka kulikonse komwe kumachitika kumawonekera ngati kusweka kwa malo m'malo mopotoka bwino (kupotoza) komwe kumachitika ngati chitsulo, motero kusunga kusalala konsekonse kwa nthawi yayitali.

Simaginito Komanso Simachita Dzimbiri: Granite simakhudzidwa ndi mphamvu zamaginito ndipo sichita dzimbiri, zomwe zimachotsa magwero awiri akuluakulu a zolakwika ndi kuipitsidwa komwe kungakhudze makina oyezera pogwiritsa ntchito maginito ndi zida zomvera.
Kuonetsetsa Kuti Moyo Wanu Uli Ndi Moyo Wautali Ndi Kusunga Magiredi Abwino
Kuchuluka kwa mbale pamwamba si chinthu chokhazikika; chiyenera kusungidwa. Kulondola kumadalira njira yoyamba yolumikizira ndi kupukuta, pomwe akatswiri aluso kwambiri amaika pamwamba mosamala mkati mwa tchati cha granite pamwamba pa mbale.
-
Kuzungulira kwa Calibration: Kuwongolera nthawi zonse komanso kovomerezeka sikungakambirane. Kuchuluka kwa kusinthasintha kumadalira mtundu wa mbale, mphamvu yogwiritsira ntchito, komanso momwe chilengedwe chilili. Mbale yowunikira yogwiritsidwa ntchito kwambiri ingafunike kuwunikira miyezi isanu ndi umodzi mpaka khumi ndi iwiri iliyonse.

Ukhondo: Fumbi ndi tinthu tating'onoting'ono ndi adani oopsa a pamwamba pa mbale. Zimagwira ntchito ngati tinthu tomwe timawononga, zomwe zimapangitsa kuti tilekere, ndipo zimapangitsa kuti ikhale yosalala. Kuyeretsa bwino ndi chotsukira chapadera cha pamwamba pa mbale ndikofunikira musanagwiritse ntchito komanso mutagwiritsa ntchito.

Kwa mabizinesi omwe amatumikira makampani olondola, kudziwa bwino mawu okhudzana ndi granite surface plate grade 1, granite surface table grade, ndi granite surface plate grade A ndikofunikira kwambiri kuti pakhale kuwonekera kwa digito. Ma injini osakira amaika patsogolo zomwe zili zodalirika, zolondola mwaukadaulo, komanso mwachindunji zomwe ogwiritsa ntchito akufuna. Nkhani yonse yomwe imafotokoza 'chifukwa chake' kumbuyo kwa ma grade, maziko asayansi a zinthu zomwe zasankhidwa, komanso tanthauzo lenileni la kuwongolera khalidwe sikuti zimangokopa makasitomala omwe angakhalepo komanso zimakhazikitsa woperekayo ngati mtsogoleri wamalingaliro pa metrology.
Malo amakono opangira zinthu ndi mainjiniya amafuna kutsimikizika kwathunthu. Granite pamwamba pake ikadali muyezo wagolide wa metrology yoyezera zinthu, ndipo kumvetsetsa njira yake yowunikira ndi gawo loyamba kuti mupeze kulondola kwapamwamba komanso kotsimikizika padziko lonse lapansi. Kusankha mbale yoyenera—kaya kulondola kwa tebulo la granite pamwamba pa kalasi 0 kapena kulondola kodalirika kwa Giredi 1—ndi ndalama zomwe zimalipira phindu pakutsimikizira khalidwe ndi kukonzanso pang'ono, kuonetsetsa kuti gawo lililonse lomwe limachoka pamalo anu likukwaniritsa zofunikira kwambiri.
