Kana zvasvika pakuyera kuyerwa, mahwendefa epamusoro egranite anoonekwa seyegoridhe. Kugadzikana kwavo kwechisikigo, kupfava kwakasarudzika, uye kuramba kupfeka kunoita kuti zvive zvakakosha mumalabhu emetrology, makamuri ekuongorora emhando yepamusoro, uye nzvimbo dzepamusoro dzekugadzira. Nekudaro, nepo vashandisi vazhinji vachitarisa pakurongeka kwepamusoro uye kushivirira, pane chimwe chinhu chakakosha chinopesvedzera zvakananga kuita uye hupenyu hurefu hweplate yegranite - ukobvu hwayo. Kunzwisisa kuti ukobvu hunotemwa sei uye kuti hune hukama sei nekuremedza huwandu uye kugadzikana kwakakosha pakusarudza iyo yakakodzera chikuva chemidziyo yako uye kuve nechokwadi chenguva refu yekuyera kurongeka.
Ukobvu hwegranite pamusoro peplate yakanyanya kupfuura kungoita dimensional yakatarwa. Ndiyo hwaro hwekuumbwa kweplate. Iko kukora kwegraniti, ndiko kukura kwayo kugona kutsigira midziyo inorema pasina kukotama kana kutsauka. Izvi zvinokanganisa zvakananga kuvimbika kweyero nekuti kunyangwe kushomeka kushoma - dzimwe nguva kuyerwa mumamicrons - kunogona kutungamira kune zvisiri izvo mukuongorora kana kuenzanisa. Ukuwo, ndiro yakakora zvakanyanyisa inogona kurema zvisingaite, inodhura, uye yakaoma kuisa. Mhinduro yakanaka iri mukuyera ukobvu nezvinodiwa zvekushandisa.
Imwe yeinonyanya kutariswa pakusarudza ukobvu huremu hwemidziyo ichaiswa pandiro. Kushandisa chiedza-chekuita - semamicroscopes, geji, kana maturusi ekuyeresa - ndiro yakatetepa inogona kukwana, sezvo mutoro wakaiswa uri muduku. Asi kana huremu huchiwedzera, saka kukora kunofanirawo kudaro. Machina akaita semashini ekuyeresa (CMMs), optical yekuyeresa masisitimu, kana anorema magadzirirwo egungano ane simba rakakura pamusoro, uye ndiro ine hukobvu husina kukwana inogona kukanganisa zvishoma nezvishoma pasi pemutoro. Nekufamba kwenguva, deformation iyi inotungamira mukurasikirwa kwekudzikama, kukanganisa icho chaicho chinangwa chekushandisa chaiyo yepasi ndiro.
Ukobvu hunoitawo basa rakakosha mukukwanisa kwendiro kuramba kukanganiswa kwezvakatipoteredza. Granite inowanzowedzera uye inobvumirana zvishoma nekuchinja kwekushisa, asi mahwendefa akakora anotonyanya kupikisa kushanduka kwekushisa. Ivo vane hombe yekupisa kwehuremu, zvichireva kuti vanobata zvishoma nezvishoma kune kusiyanisa kwetembiricha, izvo zvinobatsira kuchengetedza kugadzikana kunyange kana nharaunda yakatenderedza isingaite. Ichi chimiro chinonyanya kukosha mumashopu kana zvivako zvekugadzira apo kutonga kwekushisa kwakaoma.
Chimwe chinhu chinopesvedzerwa nehukobvu hupenyu hwenguva refu hwesevhisi yendiro yegranite. Ndiro ine ukobvu chaihwo hwekushandisa kwayo inogona kuramba yakagadzikana uye yakarurama kwemakumi emakore. Kusiyana neizvi, iyo yakatetepa zvakanyanya pamutoro wainotsigira inogona kutanga yasangana nezvinodiwa zvekudzikama asi zvishoma nezvishoma inorasikirwa nemazvo sezvo makore anofamba. Rudzi urwu rwekunonoka deformation kazhinji harudzoke uye ungangoda kudhura patsva kana kutsiva zvachose.
Zviyero zveindasitiri zvakaita seDIN, JIS, uye ASME zvinopa hukobvu hwakakurudzirwa hwemasaizi eplate akasiyana uye mamakisi echokwadi, asi izvi zvinofanirwa kutariswa nhungamiro kwete mitemo yakasimba. Chese chekushandisa chakasiyana, uye zvinhu zvakaita semutoro wakazara, kugovaniswa kwemutoro, kuvapo kwemasimba ane simba, uye rudzi rwerutsigiro runoshandiswa pasi peplate zvese zvinogona kukanganisa ukobvu hwakakodzera. Zvinogara zvichikurudzirwa kubvunza mugadziri paunenge uchitsanangura ndiro yegranite, kunyanya kune isiri-yakajairwa kana inorema-basa maapplication.
Mune mazwi anoshanda, hukama pakati pehukuru, ukobvu, uye kuita kwakatwasuka. Mahwendefa mahombe anoda ukobvu hukuru kuti achengetedze kusimba pamusoro penzvimbo yavo, uye magiredhi epamusoro anowanzoda mahwendefa akakora kuti aderedze kutsauka. Semuenzaniso, 1000 mm pamusoro peplate inoshandiswa kuongororwa zvakajairika inogona kunge yakakora 150 mm, nepo 2000 mm ndiro inotsigira muchina unorema wekuyeresa ingangoda 300 mm kana kudarika. Vagadziri vakaita seZHHIMG vanopa akadzama maratidziro uye kurodha huwandu hwemachati kutungamira vatengi kune yakanyanya dhizaini yezvavanoda.
Kuchengetedza kunobatawo basa mukuchengetedza kushanda kwegranite pamusoro peplate, pasinei nekukora kwayo. Kuchengeta nzvimbo yakachena uye isina guruva, kudzivirira kukanganisa kamwe kamwe, uye kuona kuti ndiro haina kuwandisa maitiro akakosha. Yenguva dzose calibration cheki inokurudzirwawo kuona kuti flatness inoramba iri mukati memiganhu inogamuchirwa. Nekutarisirwa kwakakodzera, ndiro yakanyatsosarudzwa yegranite inogona kuendesa zviyero zvakagadzikana uye zvakavimbika kwemakumi emakore.
Mukupedzisira, ukobvu hunopfuura kungoita kuyerwa kwemuviri - ndiyo yakakosha engineering parameter inosimbisa mashandiro, kusimba, uye nemazvo egranite pamusoro peplate. Nekunyatsofunga nezvehuremu hwemidziyo yako, nharaunda ichashandiswa ndiro, uye inotarisirwa hupenyu hwebasa, unogona kusarudza chikuva chinotsigira basa rako nemazvo kwemakore mazhinji. Sezvo kushivirira kwekugadzira kuchiwedzera kusimba uye kuyerwa kwechiyero zvakanyanya kukosha kupfuura nakare kose, kutarisisa kune zvakadzama senge plate ukobvu haungori chinodikanwa chehunyanzvi - mukana wekukwikwidza.
