Kana zvasvika pakuyera nemazvo, mapurati epamusoro egranite anoonekwa seanonyanya kukosha. Kugadzikana kwawo kwechisikigo, kusatsetseka kwakanyanya, uye kuramba kupfeka kunoita kuti ave akakosha mumarabhoritari emetrology, makamuri ekuongorora emhando yepamusoro, uye munzvimbo dzekugadzira dzemhando yepamusoro. Zvisinei, nepo vashandisi vazhinji vachitarisa pakururama kwenzvimbo uye kushivirira, pane chimwe chinhu chakakosha chinokanganisa zvakananga mashandiro uye kugara kwenguva refu kwepuratifomu yegranite - ukobvu hwayo. Kunzwisisa kuti ukobvu hunoonekwa sei uye kuti hunoenderana sei nekukwanisa kwekutakura uye kugadzikana kwakakosha pakusarudza puratifomu yakakodzera yemidziyo yako uye kuve nechokwadi chekuti kuyera kwenguva refu kwakarurama.
Ukobvu hweplate yepamusoro pegranite hausi kungoratidza divi rayo chete. Ndiyo hwaro hwechimiro cheplate. Kana granite yakakora, kugona kwayo kutsigira michina inorema pasina kukotama kana kutsauka. Izvi zvinokanganisa zvakananga kuvimbika kwekuyera nekuti kunyangwe kutsauka kudiki - dzimwe nguva kunoyerwa muma microns - kunogona kutungamira pakusarongeka mukuongorora kana kuyera. Kune rumwe rutivi, plate yakakora zvakanyanya inogona kunge yakarema zvisina kufanira, inodhura, uye yakaoma kuisa. Mhinduro yakanaka iri mukuenzanisa ukobvu nezvinodiwa zvekushandisa.
Chimwe chezvinhu zvinokosha pakusarudza ukobvu ihuremu hwemidziyo ichaiswa pandiro. Pakushandisa zvinhu zviri nyore - zvakaita semamaikorosikopu, magauge, kana maturusi madiki ekuyera - ndiro yakatetepa inogona kukwana, sezvo mutoro unoshandiswa uri mudiki. Asi sezvo huremu huchiwedzera, ukobvu hwacho hunofanirawo kukwana. Michina yakaita semichina yekuyera coordinate (CMMs), masisitimu ekuyera optical, kana zvigadziko zvemagungano zvinorema zvinoshandisa simba guru pamusoro, uye ndiro isina ukobvu hwakakwana inogona kuchinja zvishoma nezvishoma pasi pemutoro. Nekufamba kwenguva, kuchinja uku kunotungamira mukurasikirwa kwehutete, zvichikanganisa chinangwa chekushandisa ndiro yepamusoro chaiyo.
Ukobvu hunoitawo basa guru mukukwanisa kweplate kuramba kukanganiswa nezvakatipoteredza. Granite inokura uye inodzikira zvishoma kana tembiricha ikachinja, asi plate dzakakora dzinotonyanya kuramba tembiricha ikachinja. Dzine tembiricha yakakura, zvichireva kuti dzinoita zvishoma nezvishoma kana tembiricha ikachinja, izvo zvinobatsira kuchengetedza kugadzikana kwemativi kunyangwe nharaunda yakapoteredza isina kunaka. Chinhu ichi chinonyanya kukosha mumaworkshop kana munzvimbo dzekugadzira uko kudzora tembiricha kwakaoma.
Chimwe chinhu chinokonzerwa nekukora kweplate yegranite inguva refu yekushanda kwayo. Plate ine ukobvu hwakakodzera hwekushandiswa kwayo inogona kuramba yakasimba uye yakarurama kwemakumi emakore. Kusiyana neizvi, iyo yakatetepa zvakanyanya kupfuura mutoro wainotsigira inogona kutanga yasangana nezvinodiwa zvekusatsetseka asi zvishoma nezvishoma inorasikirwa nekunyatsorongeka kwayo nekufamba kwemakore. Rudzi urwu rwekuchinja kunonoka runowanzo gadziriswa uye runogona kuda kugadziriswa kunodhura kana kutsiviwa zvachose.
Mitemo yeindasitiri yakaita seDIN, JIS, uye ASME inopa ukobvu hunokurudzirwa hwemaplate akasiyana saizi uye magiredhi ekururama, asi izvi zvinofanirwa kutariswa senhungamiro kwete mitemo yakaoma. Kushandiswa kwese kwakasiyana, uye zvinhu zvakaita semutoro wese, kuti mutoro unogoverwa sei, kuvapo kwemasimba anochinja-chinja, uye rudzi rwechitsigiro chinoshandiswa pasi peplate zvese zvinogona kukanganisa ukobvu hwakakodzera. Zvinokurudzirwa nguva dzose kubvunza mugadziri kana uchitsanangura granite plate, kunyanya kune zvisiri zvemhando yepamusoro kana zvinorema.
Mukutaura kwechokwadi, hukama huripo pakati pehukuru, ukobvu, uye mashandiro zviri nyore. Maplate makuru anoda ukobvu hwakakura kuti arambe akaomerera pamusoro penzvimbo yawo, uye magiredhi epamusoro anowanzoda maplate akakora kuti aderedze kutsauka. Semuenzaniso, plate yepamusoro ye1000 mm inoshandiswa pakuongorora kwakajairika inogona kunge yakakora ye150 mm, nepo plate ye2000 mm inotsigira muchina unorema wekuyera ingada 300 mm kana kupfuura. Vagadziri vakaita seZHHIMG vanopa tsanangudzo dzakadzama nemachati ekutakura mutoro kuti vatungamire vatengi kudhizaini yakakodzera zvavanoda.
Kugadzirisa kunoitawo basa rekuchengetedza mashandiro eplate yegranite pamusoro, pasinei nekukora kwayo. Kuchengetedza pamusoro payo kwakachena uye kusina guruva, kudzivirira kurovera kamwe kamwe, uye kuona kuti plate yacho haina kuzara zvakanyanya inzira dzakakosha. Kuongororwa nguva dzose kwekuongorora kunokurudzirwawo kuti uone kuti yakati sandara inoramba iri mukati memiganhu inogamuchirika. Nekutarisirwa kwakakodzera, plate yegranite yakasarudzwa zvakanaka inogona kupa zviyero zvakagadzikana uye zvakavimbika kwemakumi emakore.
Pakupedzisira, ukobvu hausi kungoyera chete — ipfungwa inokosha yeinjiniya inotsigira mashandiro, kugara kwenguva refu, uye kurongeka kweplate yegranite pamusoro. Nekunyatsoongorora huremu hwemidziyo yako, nharaunda iyo plate ichashandiswa, uye hupenyu hwebasa hunotarisirwa, unogona kusarudza puratifomu inotsigira basa rako rekunyatsorongeka kwemakore mazhinji. Sezvo kushivirira kwekugadzira kuri kuramba kuchiwedzera uye kurongeka kwekuyera kuchikosha kupfuura kare, kutarisisa zvinhu zvakaita seukobvu hweplate hakusi kungodiwa chete — inyaya yemakwikwi.
