Ma granite pamwamba ndi ofunikira kwambiri poyesa molondola, amagwira ntchito zofunika kwambiri pakuwunika uinjiniya, kuwunikira zida, ndi kutsimikizira miyeso yonse ya zinthu pakupanga ndege, magalimoto, ndi zida zamankhwala. Mosiyana ndi mipando ya granite wamba (monga matebulo, matebulo a khofi), ma granite apamwamba a mafakitale amapangidwa kuchokera ku granite yapamwamba kwambiri ya Taishan Green (yochokera ku Taishan, Shandong Province) - nthawi zambiri mu mitundu yosiyanasiyana ya granular ya Taishan Green kapena Green-White. Yopangidwa kudzera mu makina opukutira olondola amanja kapena makina opukutira apadera a CNC, ma mbale awa amapereka kusalala kwapadera, kusalala kwa pamwamba, komanso kukhazikika kwa miyeso, kutsatira miyezo yokhwima yamakampani (monga ISO 8512, ASME B89.3.1).
Ubwino waukulu wa miyala ya granite pamwamba uli mu kachitidwe kawo kapadera kowonongeka: ngakhale itakanda mwangozi ikagwiritsidwa ntchito, kuwonongeka nthawi zambiri kumawonekera ngati madontho ang'onoang'ono osatuluka m'malo mwa madontho okwera - chinthu chofunikira kwambiri chomwe chimasunga kulondola kwa muyeso. Komabe, kupewa madontho ndikofunikira kwambiri kuti musunge kulondola kwa nthawi yayitali ndikupewa kukonzanso kapena kusintha ndalama zambiri. Bukuli likufotokoza zomwe zimayambitsa madontho ndi njira zomwe zingagwiritsidwe ntchito poteteza miyala yanu ya granite pamwamba, yopangidwira opanga miyeso yolondola komanso magulu owongolera khalidwe.
1. Ubwino Waukulu wa Mapepala a Granite (Chifukwa Chake Amapambana Zipangizo Zina)
Musanakambirane za kupewa kuonongeka kwa mano, ndikofunikira kufotokoza chifukwa chake granite ikadali chisankho chabwino kwambiri pakugwiritsa ntchito molondola - kulimbitsa phindu lake kwa opanga omwe akugwiritsa ntchito ndalama pakudalirika kwa nthawi yayitali:
- Kuchulukana kwapamwamba ndi kufanana: Kuchulukana kwa mchere wa Granite (2.6-2.7 g/cm³) ndi kapangidwe kofanana kumatsimikizira kukhazikika kwapadera, kuchita bwino kwambiri kuposa zitsulo kapena mbale zophatikizika zomwe zingapindike pansi pa kupsinjika.
- Kukana kuwonongeka ndi dzimbiri: Imakana kusweka chifukwa chogwiritsidwa ntchito nthawi zonse ndipo imapirira kukhudzidwa ndi ma asidi ofatsa, zoziziritsira, ndi zosungunulira za mafakitale — yabwino kwambiri m'malo ovuta ogwirira ntchito.
- Zinthu zopanda maginito: Mosiyana ndi mbale zachitsulo, granite siisunga maginito, zomwe zimachotsa kusokoneza kwa zida zoyezera maginito (monga zizindikiro za maginito, maginito chucks).
- Kukulitsa kutentha kochepa: Ndi kuchuluka kwa kutentha kwa ~0.8×10⁻⁶/°C, granite sikhudzidwa kwambiri ndi kusinthasintha kwa kutentha, zomwe zimapangitsa kuti miyeso ikhale yofanana ngakhale m'malo osiyanasiyana ogwirira ntchito.
- Kulekerera kuwonongeka: Monga taonera, mikwingwirima yaying'ono imabweretsa mabowo osaya (osati m'mphepete mokwezeka), zomwe zimalepheretsa kuwerengedwa kolakwika panthawi yowunikira kusalala kapena kuyang'ana kwa workpiece - chinthu chofunikira chosiyanitsa ndi mbale zachitsulo, komwe mikwingwirima ingapangitse ma burrs otuluka.
2. Zomwe Zimayambitsa Madontho mu Granite Surface Plates
Kuti mupewe kusweka bwino, choyamba dziwani zomwe zimayambitsa vuto - zambiri zimachokera ku kusagwira bwino ntchito, kuchuluka kwa zinthu, kapena kukhudzana ndi zinthu zolimba/zosagwira ntchito:
- Kulemera kwambiri kwa malo: Kuyika zida zolemera (kupitirira katundu wovomerezeka wa mbale) kapena kugwiritsa ntchito mphamvu yowonjezereka (monga, kukanikiza chinthu cholemera pamalo amodzi) kungathe kukanikiza kapangidwe ka kristalo ka granite, ndikupanga mabowo okhazikika.
- Kugundana ndi zinthu zolimba: Kugundana mwangozi ndi zida zachitsulo (monga nyundo, mabuleki), zidutswa za ntchito, kapena zida zoyezera zomwe zagwa zimasamutsa mphamvu yayikulu pamwamba pa granite, zomwe zimapangitsa kuti pakhale mabala akuya kapena ming'alu.
- Kuipitsidwa ndi tinthu tating'onoting'ono: Zitsulo zodulidwa, fumbi la emery, kapena mchenga womangika pakati pa chogwirira ntchito ndi pamwamba pa mbale zimakhala ngati zomangira poyesa. Pamene kupanikizika kukugwiritsidwa ntchito (monga kutsetsereka kwa chogwirira ntchito), tinthu tating'onoting'ono timeneti timakanda granite, n’kusanduka madontho ang'onoang'ono pakapita nthawi.
- Zipangizo zoyeretsera zosayenerera: Kugwiritsa ntchito maburashi otsukira, ubweya wachitsulo, kapena zotsukira zonyamulira zimatha kupukuta pamwamba popukutidwa, ndikupanga madontho ang'onoang'ono omwe amasonkhanitsa ndikuwononga kulondola.

3.1 Kusamalira Katundu Mokhwima (Pewani Kulemera Kwambiri & Kupanikizika Kwambiri)
- Tsatirani malire a katundu wovomerezeka: Mbale iliyonse ya granite pamwamba ili ndi katundu wodziwika bwino (monga, 500 kg/m² ya mbale wamba, 1000 kg/m² ya zitsanzo zolemera). Tsimikizirani mphamvu ya katundu wa mbaleyo musanayike zida zogwirira ntchito — musapitirire, ngakhale kwakanthawi.
- Onetsetsani kuti kulemera kumagawidwa mofanana: Gwiritsani ntchito ma block othandizira kapena mbale zofalitsira zinthu poyika zinthu zolemera kapena zosaoneka bwino (monga ma castings akuluakulu). Izi zimachepetsa kuthamanga kwa mpweya komwe kumachitika pamalo amodzi, zomwe zimathandiza kupewa kusweka kwa zinthu chifukwa cha kuyika zinthu pamalo amodzi.
- Pewani kugwira ntchito mwamphamvu kwambiri: Mukagwira ntchito ndi ma clamp, gwiritsani ntchito ma torque wrench kuti muwongolere kupanikizika. Ma clamp omangika kwambiri amatha kufinya pamwamba pa granite pamalo olumikizirana ndi clamp, ndikupanga mabowo.
Chidziwitso Chofunika: Pazinthu zomwe zimagwiritsidwa ntchito mwamakonda (monga zida zazikulu kwambiri zamlengalenga), gwirizanani ndi opanga kuti apange mbale za granite zokhala ndi mphamvu yolimba yonyamula katundu - izi zimachotsa chiopsezo cha kusweka chifukwa cha kuchuluka kwa zinthu.
3.2 Chitetezo ku Zoopsa (Kuletsa Kugundana Panthawi Yogwira Ntchito ndi Kugwiritsa Ntchito)
- Gwirani mosamala mukamayenda: Gwiritsani ntchito zolimbitsira zophimba kapena zonyamula vacuum (osati zingwe zachitsulo) kuti musunthe mbale za granite. Manga m'mphepete ndi thovu loletsa kugundana kuti muchepetse kugwedezeka ngati mwangozi mwachitika matumphu.
- Ikani zotetezera malo ogwirira ntchito: Ikani ma pad a rabara kapena polyurethane buffer m'mphepete mwa mabenchi ogwirira ntchito, zida zamakina, kapena zida zapafupi - izi zimagwira ntchito ngati chotchinga ngati mbale kapena zotetezera zisuntha mosayembekezereka.
- Letsani kukhudzana ndi zida zolimba: Musayike kapena kugwetsa zida zolimba zachitsulo (monga nyundo, zobowolera, nsagwada za caliper) mwachindunji pamwamba pa granite. Gwiritsani ntchito mathireyi apadera a zida kapena mphasa zofewa za silicone kuti musunge zida pafupi ndi mbale.
3.3 Kusamalira Malo Ozungulira (Kuteteza Kuwonongeka Kosakhazikika)
- Tsukani musanagwiritse ntchito komanso mutagwiritsa ntchito: Pukutani pamwamba pa mbaleyo ndi nsalu ya microfiber yopanda ulusi wothira ndi chotsukira chosawononga pH (monga chotsukira chapadera cha granite surface). Izi zimachotsa zitsulo zodulidwa, zotsalira zoziziritsira, kapena fumbi zomwe zingayambitse madontho ang'onoang'ono panthawi yoyezera.
- Pewani kukhudzana ndi zinthu zokwawa: Musagwiritse ntchito mbaleyo kupukuta choziziritsira chouma, chothira madzi, kapena dzimbiri — izi zimakhala ndi tinthu tolimba tomwe timakanda pamwamba. M'malo mwake, gwiritsani ntchito chotsukira cha pulasitiki (osati chitsulo) kuti muchotse zinyalala pang'onopang'ono.
- Kuyang'ana pafupipafupi kwa ma micro-dents: Gwiritsani ntchito choyezera kulunjika bwino kapena laser flatness kuti muwone ngati pali ma micro-dents obisika pamwezi. Kuzindikira koyambirira kumalola akatswiri kupukuta (ndi akatswiri ovomerezedwa ndi ISO) kuti akonze zowonongeka zazing'ono zisanakhudze muyeso.
4. Cholepheretsa Chofunika Kwambiri pa Adilesi: Kufooka
Ngakhale kuti miyala ya granite pamwamba pake ndi yabwino kwambiri polimbana ndi makwinya (mosiyana ndi makwinya otuluka), kufooka kwawo kwakukulu ndi kusweka — kugwedezeka kwakukulu (monga kugwetsa chitsulo) kungayambitse ming'alu kapena zipsera, osati makwinya okha. Kuti muchepetse izi:
- Aphunzitsi othandizira pa njira zoyenera zoyendetsera zinthu (monga, osayendetsa pafupi ndi malo ogwirira ntchito okhala ndi mbale za granite).
- Gwiritsani ntchito zoteteza m'mphepete (zopangidwa ndi rabara yolimbikitsidwa) pamakona onse a mbale kuti muchepetse kugwedezeka.
- Sungani mbale zosagwiritsidwa ntchito m'malo osungiramo zinthu omwe amasungidwa bwino komanso otetezedwa ndi nyengo — pewani kuyika mbale zambiri kapena kuyika zinthu zolemera pamwamba pake.
Mapeto
Kuteteza ma granite pamwamba pa ma plates sikuti kungosunga mawonekedwe awo okha - koma kuteteza kulondola komwe kumayendetsa bwino kapangidwe kanu. Mwa kutsatira malamulo okhwima okhudza katundu, kuteteza kugwedezeka, ndi njira zosamalira pamwamba, mutha kukulitsa moyo wa plate yanu (nthawi zambiri ndi zaka 7+) ndikuchepetsa ndalama zoyezera, ndikuwonetsetsa kuti ikutsatira miyezo ya ISO 8512 ndi ASME.
Ku [Dzina Lanu la Mtundu], timapanga ma granite apamwamba opangidwa kuchokera ku granite yapamwamba ya Taishan Green — mbale iliyonse imaphwanyidwa bwino kwambiri ndi masitepe 5 komanso kufufuzidwa bwino kuti isagwedezeke ndikuwonetsetsa kuti imakhala yokhazikika kwa nthawi yayitali. Kaya mukufuna mbale yokhazikika ya 1000×800mm kuti iwunikidwe kapena yankho lapadera la zida zoyendera ndege, gulu lathu limapereka zinthu zotsimikizika ndi ISO ndi chithandizo chaukadaulo cha maola 24 pa sabata. Lumikizanani nafe lero kuti mukambirane zomwe mukufuna ndikulandira mtengo waulere, wopanda kukakamizidwa.
