Ponena za kuyeza molondola, ma granite pamwamba amaonedwa ngati muyezo wagolide. Kukhazikika kwawo kwachilengedwe, kusalala kwapadera, komanso kukana kuvala kumapangitsa kuti akhale ofunikira kwambiri m'ma laboratories a metrology, zipinda zowunikira zabwino, komanso m'malo opangira zinthu zapamwamba. Komabe, ngakhale ogwiritsa ntchito ambiri amayang'ana kwambiri kulondola kwa pamwamba ndi kulekerera, pali chinthu china chofunikira chomwe chimakhudza mwachindunji magwiridwe antchito ndi moyo wautali wa granite plate - makulidwe ake. Kumvetsetsa momwe makulidwe amadziwidwira komanso momwe amagwirizanirana ndi mphamvu ya katundu ndi kukhazikika ndikofunikira kwambiri posankha nsanja yoyenera ya zida zanu ndikuwonetsetsa kuti miyeso ya nthawi yayitali ndi yolondola.
Kukhuthala kwa mbale ya granite pamwamba sikutanthauza kuti ndi yofanana ndi kukula kwake. Ndi maziko a kapangidwe ka mbaleyo. Granite ikakula, mphamvu yake yothandizira zida zolemera imakula popanda kupindika kapena kupotoka. Izi zimakhudza mwachindunji kudalirika kwa muyeso chifukwa ngakhale kupotoka kochepa - nthawi zina kumayesedwa mu ma micron - kungayambitse zolakwika pakuwunika kapena kuwerengera. Kumbali ina, mbale yokhuthala kwambiri ingakhale yolemera mosafunikira, yokwera mtengo, komanso yovuta kuyiyika. Yankho labwino kwambiri lili pakulinganiza makulidwe ndi zofunikira za ntchitoyo.
Chimodzi mwa zinthu zofunika kuziganizira podziwa makulidwe ndi kulemera kwa zida zomwe zidzaikidwe pa mbale. Pazinthu zopepuka - monga ma microscope, ma gauge, kapena zida zazing'ono zoyezera - mbale yopyapyala ikhoza kukhala yokwanira, chifukwa katundu wogwiritsidwa ntchito ndi wochepa. Koma pamene kulemera kukuwonjezeka, makulidwe akenso ayenera kukhala okwanira. Makina monga makina oyezera ogwirizana (CMMs), makina oyezera owoneka bwino, kapena zida zolemetsa zolemera zimakhala ndi mphamvu yayikulu pamwamba, ndipo mbale yokhala ndi makulidwe osakwanira imatha kusokonekera pang'onopang'ono pansi pa katunduyo. Pakapita nthawi, kusinthaku kumabweretsa kutayika kwa kusalala, zomwe zimapangitsa kuti cholinga chogwiritsa ntchito mbale yolondola pamwamba pake chikhale chovuta.
Kukhuthala kumakhalanso kofunikira kwambiri pa luso la mbale yolimbana ndi zinthu zachilengedwe. Mwachibadwa, granite imakula ndi kuchepetsedwa pang'ono ndi kusintha kwa kutentha, koma mbale zokhuthala zimapirira kwambiri kusinthasintha kwa kutentha. Zili ndi kutentha kwakukulu, zomwe zikutanthauza kuti zimachita pang'onopang'ono kusintha kwa kutentha, zomwe zimathandiza kusunga kukhazikika kwa mawonekedwe ngakhale malo ozungulira sali abwino. Mbali imeneyi ndi yofunika kwambiri m'mafakitale kapena m'malo opangira zinthu komwe kuwongolera kutentha kumakhala kovuta.
Mbali ina yomwe imakhudzidwa ndi makulidwe ake ndi nthawi yayitali yogwirira ntchito ya mbale ya granite. Mbale yokhala ndi makulidwe oyenera kuti igwiritsidwe ntchito imatha kukhala yokhazikika komanso yolondola kwa zaka zambiri. Mosiyana ndi zimenezi, yomwe ndi yopyapyala kwambiri moti singakwane katundu womwe imanyamula poyamba ingakwaniritse zofunikira za kusalala koma pang'onopang'ono imataya kulondola kwake pakapita zaka. Mtundu uwu wa kusintha pang'onopang'ono nthawi zambiri sungathe kusinthidwa ndipo ungafunike kukonzanso zinthu modula kapena kusinthidwa kwathunthu.
Miyezo yamakampani monga DIN, JIS, ndi ASME imapereka makulidwe ofunikira a kukula kosiyanasiyana kwa mbale ndi magiredi olondola, koma izi ziyenera kuonedwa ngati malangizo osati malamulo okhwima. Kugwiritsa ntchito kulikonse ndi kwapadera, ndipo zinthu monga katundu wonse, momwe katunduyo amagawidwira, kukhalapo kwa mphamvu zosinthika, ndi mtundu wa kapangidwe kothandizira komwe kamagwiritsidwa ntchito pansi pa mbale zonse zimatha kukhudza makulidwe oyenera. Nthawi zonse ndibwino kufunsa wopanga mukasankha mbale ya granite, makamaka pa ntchito zosakhala zachizolowezi kapena zolemera.
Mwachidule, ubale pakati pa kukula, makulidwe, ndi magwiridwe antchito ndi wosavuta. Ma plate akuluakulu amafunika makulidwe akuluakulu kuti asunge kulimba pamwamba pawo, ndipo ma grade olondola kwambiri nthawi zambiri amafuna ma plate okhuthala kuti achepetse kupotoka. Mwachitsanzo, plate ya pamwamba ya 1000 mm yomwe imagwiritsidwa ntchito poyang'ana kwambiri ikhoza kukhala ndi makulidwe a 150 mm, pomwe plate ya 2000 mm yothandizira makina olemera ingafunike 300 mm kapena kuposerapo. Opanga monga ZHHIMG amapereka tsatanetsatane watsatanetsatane ndi ma chart a mphamvu yonyamula katundu kuti atsogolere makasitomala ku kapangidwe koyenera kwambiri pazosowa zawo.
Kusamaliranso kumathandizanso kuti mbale ya granite pamwamba igwire ntchito bwino, mosasamala kanthu za makulidwe ake. Kusunga pamwamba pa granite kukhala paukhondo komanso popanda fumbi, kupewa kugundana mwadzidzidzi, komanso kuonetsetsa kuti mbaleyo siikudzaza ndi zinthu zambiri ndi njira zofunika kwambiri. Kuyang'ana pafupipafupi pakuwunikanso kumalimbikitsidwanso kuti zitsimikizire kuti kusalala kwake kuli mkati mwa malire oyenera. Ndi chisamaliro choyenera, mbale ya granite yosankhidwa bwino imatha kupereka miyeso yokhazikika komanso yodalirika kwa zaka zambiri.
Pamapeto pake, makulidwe si kungoyerekeza chabe — ndi njira yofunika kwambiri yopangira zinthu yomwe imatsimikizira magwiridwe antchito, kulimba, komanso kulondola kwa mbale ya granite pamwamba. Poganizira mosamala kulemera kwa zida zanu, malo omwe mbaleyo idzagwiritsidwe ntchito, komanso nthawi yomwe ikuyembekezeka yogwirira ntchito, mutha kusankha nsanja yomwe ingakuthandizeni kugwira ntchito yanu molondola kwa zaka zambiri. Pamene kulekerera kwa kupanga kukukulirakulira komanso kulondola kwa muyeso kuli kofunika kwambiri kuposa kale lonse, kulabadira tsatanetsatane monga makulidwe a mbale sikuti ndi chinthu chofunikira paukadaulo kokha — ndi mwayi wopikisana.
