Makina oyezera atatu (CMMs) ndi zida zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana opanga zinthu kuti ayesere kukula kolondola, mawonekedwe, ndi malo a zomangamanga zovuta za 3D. Kulondola ndi kudalirika kwa makinawa ndikofunikira kwambiri pakutsimikizira mtundu wa chinthu chomaliza, ndipo chinthu chimodzi chofunikira chomwe chimathandizira magwiridwe antchito awo ndi gawo lofunikira lomwe limayang'anira njira yoyezera: mbale ya pamwamba ya granite.
Granite imadziwika ndi makhalidwe ake apadera, kuphatikizapo kuuma kwake kwakukulu, kufalikira kwa kutentha pang'ono, komanso mphamvu yabwino kwambiri yochepetsera chinyezi. Makhalidwe amenewa amawapangitsa kukhala chinthu choyenera kwambiri kwa ma CMM, omwe amafunikira maziko olimba komanso olimba kuti athandizire ma probe awo oyezera ndikupereka deta yolondola komanso yogwirizana. M'nkhaniyi, tifufuza zabwino za granite monga gawo lalikulu la ma CMM ndi momwe zimathandizira pakugwira ntchito kwawo.
1. Kuuma: Granite ili ndi modulus yapamwamba kwambiri ya Young, zomwe zikutanthauza kuti imapirira kwambiri kusinthika ikagwiritsidwa ntchito ndi makina. Kuuma kumeneku kumaonetsetsa kuti mbale ya granite pamwamba imakhala yosalala komanso yokhazikika pansi pa kulemera kwa chitsanzo kapena choyezera, kuteteza kupotoka kulikonse kosafunikira komwe kungasokoneze kulondola kwa miyeso. Kuuma kwakukulu kwa granite kumalolanso ma CMM kumangidwa ndi mbale zazikulu za granite pamwamba, zomwe zimapatsa malo ambiri a zigawo zazikulu komanso ma geometries ovuta kwambiri.
2. Kukhazikika kwa kutentha: Granite ili ndi kuchuluka kochepa kwambiri kwa kutentha, zomwe zikutanthauza kuti siimakula kapena kufupika kwambiri ikakumana ndi kusintha kwa kutentha. Katunduyu ndi wofunikira kwambiri kwa ma CMM chifukwa kusintha kulikonse kwa kukula kwa mbale pamwamba chifukwa cha kusintha kwa kutentha kungapangitse zolakwika muyeso. Mapepala pamwamba pa granite amatha kupereka miyeso yokhazikika komanso yodalirika ngakhale m'malo omwe kutentha kumakhala kosinthasintha kwambiri, monga mafakitale kapena ma labotale.
3. Mphamvu Yothira Madzi: Granite ili ndi mphamvu yapadera yoyamwa madzi ogwedezeka ndikuletsa kuti asakhudze miyeso. Kugwedezeka kungachokere m'malo osiyanasiyana monga kugwedezeka kwa makina, makina ogwiritsira ntchito, kapena zochita za anthu pafupi ndi CMM. Mphamvu yothira madzi ya granite imathandiza kuchepetsa kugwedezeka kwa madziwo ndikuwonetsetsa kuti sapanga phokoso kapena zolakwika zoyezera. Katunduyu ndi wofunikira kwambiri pogwira ntchito ndi zinthu zovuta komanso zofewa kapena poyezera molondola kwambiri.
4. Kulimba: Granite ndi chinthu cholimba kwambiri komanso cholimba chomwe chingathe kupirira kugwiritsidwa ntchito kwa nthawi yayitali komanso kugwiritsidwa ntchito molakwika m'mafakitale. Sichimakhudzidwa ndi kukanda, dzimbiri, komanso kuwonongeka, zomwe zimapangitsa kuti ikhale chisankho chabwino kwambiri cha chinthu chomwe chiyenera kupereka miyeso yokhazikika komanso yolondola kwa nthawi yayitali. Mapepala a granite pamwamba amafunika kusamalidwa pang'ono ndipo amatha kukhalapo kwa zaka zambiri, zomwe zimapangitsa kuti CMM ikhale yogwiritsidwa ntchito kwa nthawi yayitali.
5. Yosavuta kuyeretsa: Granite ndi yosavuta kuyeretsa ndi kusamalira, zomwe zimapangitsa kuti ikhale yogwiritsidwa ntchito m'mafakitale. Malo ake opanda mabowo amalimbana ndi chinyezi ndi kukula kwa mabakiteriya, kuchepetsa chiopsezo cha kuipitsidwa ndikuwonetsetsa kuti miyeso yake ndi yolondola. Mapepala a granite amatha kutsukidwa mwachangu ndi madzi ndi sopo ndipo safuna khama lalikulu kuti asungidwe bwino.
Pomaliza, granite monga gawo lalikulu la CMMs imapereka ubwino waukulu womwe umathandizira kuti igwire bwino ntchito komanso kudalirika. Kulimba, kukhazikika kwa kutentha, mphamvu yonyowa, kulimba, komanso kuyeretsa kosavuta zimapangitsa granite kukhala chisankho chabwino kwambiri cha gawo lomwe liyenera kupereka miyeso yolondola komanso yokhazikika pansi pa mikhalidwe yosiyanasiyana. CMMs zomangidwa ndi mbale za granite pamwamba zimakhala zolimba, zokhazikika, komanso zolondola, zomwe zimapangitsa kuti zikhale zodalirika komanso zolondola kwambiri popanga zinthu zapamwamba.
