M'dziko la ultra-precision metrology, chida choyezera cha granite si mwala wolemera chabe; ndiye muyezo wofunikira womwe miyeso ina yonse imayesedwa. Kulondola komaliza komaliza - komwe kumapezeka mumtundu wa micron ndi sub-micron - kumayamba kalekale isanafike njira yomaliza, mosamala kwambiri. Koma kodi ndi njira zotani zoyambilira zomwe zinayambitsadi kulondola kosayerekezeka koteroko? Zimayamba ndi magawo awiri ofunikira, oyambira: kusankha mokhazikika kwa zida za granite yaiwisi ndi njira yodulira yolondola kwambiri yomwe imagwiritsidwa ntchito kuti ipange.
Luso ndi Sayansi Yosankha Zinthu
Si granite yonse yomwe imapangidwa mofanana, makamaka pamene mapeto ayenera kukhala chida chokhazikika, choyezera kalasi ngati mbale ya pamwamba, tri-square, kapena m'mphepete mwawongoka. Njira yosankha ndi yasayansi kwambiri, ikuyang'ana kwambiri zakuthupi zomwe zimatsimikizira kukhazikika kwazaka zambiri.
Timafunafuna makamaka mitundu ya granite yakuda yochuluka kwambiri. Mtunduwu umasonyeza kuchuluka kwa mchere wambiri, wakuda, monga hornblende, ndi kapangidwe kake kakang'ono. Zolemba izi sizingangolephereka chifukwa cha ntchito yolondola pazifukwa zingapo zazikulu. Choyamba, Low Porosity ndi High Density ndizofunika kwambiri: mawonekedwe olimba, owoneka bwino amachepetsa voids mkati ndikukulitsa kachulukidwe, komwe kumatanthawuza mwachindunji kuziziritsa kwamkati kwapamwamba. Kutentha kwakukulu kumeneku ndikofunikira kuti makina azigwedezeka mwachangu, kuwonetsetsa kuti malo oyezera amakhalabe okhazikika. Kachiwiri, zinthuzo ziyenera kuwonetsa Coefficient Yotsika Kwambiri Yowonjezera Kutentha (COE). Katunduyu ndi wofunikira, chifukwa amachepetsa kukulitsa kapena kutsika ndi kusinthasintha kwa kutentha komwe kumayendetsedwa bwino, kutsimikizira kuti chidacho chimasunga kukhulupirika kwake. Pomaliza, granite yosankhidwayo iyenera kukhala ndi mphamvu zopondereza kwambiri komanso Kugawa kwa Mineral Uniform. Kufanana kumeneku kumatsimikizira kuti zinthuzo zimayankhidwa motsimikizika panthawi yodula komanso, koposa zonse, gawo lovuta kwambiri lachiwongolero, zomwe zimatilola kuti tikwaniritse ndikusunga kulolerana kwathu kofunikira.
Njira Yodula Mwapamwamba
Kachida koyenera kakachotsedwa ku miyala, gawo loyambirira lopangira - kudula - ndi njira yaukadaulo yamafakitale yopangidwira kuchepetsa kupsinjika kwa zinthu ndikukhazikitsa njira yomaliza mwaluso kwambiri. Njira zodulira zomangira zachikale ndizosakwanira; kulondola kwa granite kumafuna zida zapadera.
Njira yamakono yamakono yodula chipika chachikulu cha granite ndi Diamond Wire Saw. Njirayi imalowa m'malo mwa masamba ozungulira achikhalidwe ndi chingwe chokhazikika chachitsulo champhamvu champhamvu chophatikizidwa ndi diamondi zamakampani. Kugwiritsiridwa ntchito kwa njirayi kumapereka ubwino wosiyana: kumatsimikizira Kuchepetsa Kupsinjika ndi Kutentha chifukwa mawaya a diamondi akugwira ntchito mosalekeza, maulendo angapo, omwe amagawa mphamvu zodulira mofanana pazinthu zonse. Izi zimachepetsa chiopsezo chobweretsa kupsinjika kotsalira kapena ming'alu yaying'ono mu granite-chowopsa chofala ndi njira imodzi yokha, yodula kwambiri. Chofunika kwambiri, njirayi imakhala yonyowa, pogwiritsa ntchito madzi osasunthika kuziziritsa waya ndikuchotsa fumbi la granite, motero kupewa kuwonongeka kwa kutentha komwe kungasokoneze kukhazikika kwa zinthuzo kwanthawi yayitali. Njirayi imalolanso Kugwira Ntchito ndi Kukula, kupangitsa kuti midadada ipangidwe bwino kwambiri - yofunikira pamiyala yayikulu yamtundu wa granite kapena zoyambira zamakina - yokhala ndi chiwongolero chomwe sichinachitikepo m'mbuyomu, ndikupereka geometry yolondola yoyambira yomwe imachepetsa kwambiri nthawi ndi zinyalala zakuthupi zomwe zimakhudzidwa ndi magawo omwe akupera movutikira.
Poyang'ana mosalekeza pa kusankha kwa zinthu zabwino kwambiri zowundana, zokhazikika komanso kugwiritsa ntchito njira zapamwamba zochepetsera kupsinjika, tikuwonetsetsa kuti chida chilichonse choyezera mwala wa ZHHIMG chimapangidwa ndi mtundu wachilengedwe wofunikira kuti muyezedwe bwino kwambiri padziko lonse lapansi. Kudumpha mosamalitsa komwe kumatsatira ndikungomaliza chabe munjira yopangidwa mwaluso.
