Ma granite pamwamba amapereka kukhazikika kwa kutentha komanso kulimba kwambiri poyerekeza ndi njira zina zachitsulo, zomwe zimapangitsa kuti akhale malo ofunikira kwambiri poyezera molondola m'ma lab ndi ma workshop padziko lonse lapansi.
Kwa zaka zambiri, mainjiniya owongolera khalidwe akhala akugwiritsa ntchitombale za granite pamwambamonga maziko oyambira a metrology yofanana. Ngakhale kupita patsogolo kwa sayansi ya zinthu, miyala yayikulu iyi, yopangidwa bwino kwambiri, ikupitilizabe kulamulira zipinda zowunikira, maziko a CMM, ndi ma laboratories owunikira m'mafakitale osiyanasiyana kuyambira kupanga ndege mpaka kupanga ma semiconductor. Funso silili ngati granite ndi yodalirika - yadzitsimikizira yokha kwa mibadwomibadwo - koma mtundu uti, katundu wazinthu ziti, ndi wogulitsa uti amene angakwaniritse kulekerera kokhwima kwa zinthu zamakono.
Chifukwa Chake Granite Imachita Bwino Kuposa Chitsulo Poyesa Molondola
Kapangidwe ka granite kamaipangitsa kukhala yoyenera kugwiritsidwa ntchito ngati malo oyezera. Mosiyana ndi chitsulo kapena chitsulo chopangidwa ndi chitsulo, granite imakhala ndi kukhazikika kwa kutentha kwambiri - kuchuluka kwake kwa kutentha kumakhala kochepa kwambiri, zomwe zikutanthauza kuti kukula kwa mbaleyo kumasintha pang'ono kutentha kwa malo ozungulira kukasintha. Mwachidule, izi zikutanthauza kuti pamwamba pake pamakhala posalala tsiku lonse la ntchito, ngakhale m'malo opanda kuwongolera bwino nyengo.
Granite imalimbananso ndi kupindika ndi kusinthika ikadzazidwa. Granite yomwe imathandizidwa bwino pamwamba pake idzakhalabe ndi mawonekedwe ake osalala kwa zaka zambiri popanda kukonza kwambiri. Ma laboratories ambiri abwino amagwiritsabe ntchito ma plates apamwamba omwe ali ndi zaka 20 kapena 30, ndipo kukonza kokha komwe kumafunika ndi kuyeretsa nthawi ndi nthawi ndikusintha mtundu wa flatness.
Mosiyana ndi zimenezi, ma plate achitsulo pamwamba pake amakhala ndi dzimbiri ndipo amafunika zokutira zoteteza zomwe zingayambitse zolakwika muyeso. Ma plate achitsulo opangidwa ndi chitsulo amatha kutengeka mosavuta ndi kutentha. Pa ntchito iliyonse yomwe miyeso ya sub-micron ndi yofunika, granite ndiye chisankho chodziwikiratu.
Kumvetsetsa Magiredi Okhala ndi Mbale Yokwera
Ma plates pamwamba amagawidwa m'magulu malinga ndi kulekerera kwa flatness, nthawi zambiri amatsatira miyezo monga ASTM GGG-P-463C, DIN 876, kapena ISO 8512. Ma grade odziwika kwambiri ndi awa:
- · Giredi 00: Kupatuka kwa kusalala ≤0.5 μm/m — yogwiritsidwa ntchito pa ma laboratories ovuta kwambiri owerengera ndi ntchito zowunikira
- · Giredi 0: Kupatuka kwa kusalala ≤1 μm/m — koyenera kuyang'aniridwa ndi magulu onse a CMM
- · Giredi 1: Kupatuka kwa kusalala ≤2 μm/m — koyenera kuyang'anira ndi kupanga zida pamlingo wa msonkhano
Pa ntchito zambiri zowongolera khalidwe la mafakitale, Giredi 0 imapereka mgwirizano wabwino kwambiri pakati pa mtengo ndi magwiridwe antchito. Ma plate a Giredi 00 nthawi zambiri amasungidwa ku mabungwe adziko lonse oyesa zinthu ndi ma laboratories oyesa zinthu kumene kumafunika kutsatira miyezo ya dziko.
Mukasankhambale ya pamwamba, ogula ayenera kutsimikizira muyezo woyenera wa makampani awo. Mapangano a ndege ndi chitetezo nthawi zambiri amafuna miyezo ya ASTM, pomwe opanga aku Europe amatha kutchula DIN 876. Wopereka woyenerera ayenera kukhala wokhoza kupanga ndikutsimikizira miyezo iliyonse mwa iyi.
Zinthu Zakuthupi: Chifukwa Chake Black Granite Imakonda
Si granite yonse yomwe imapangidwa mofanana. Granite wakuda — makamaka mitundu ina yokhala ndi mchere wambiri — imapereka mawonekedwe abwino kwambiri pakugwiritsa ntchito molondola miyeso. Zofunikira kwambiri ndi kuchulukana ndi kapangidwe ka mchere.
Granite wakuda wokhuthala kwambiri (nthawi zambiri pafupifupi 3,100 kg/m³) umapereka kukhazikika bwino komanso kukana kuwonongeka poyerekeza ndi mitundu yopepuka ya granite. Zipangizo zotsika mtengo, kuphatikizapo zinthu zina zolowa m'malo mwa marble zomwe nthawi zina zimaperekedwa ndi ogulitsa ochepetsa ndalama, sizingasunge kuthyathyathya pakapita nthawi ndipo zimatha kuyambitsa zolakwika zoyezera.
Ogula omwe akufuna kugula ayenera kupempha ogulitsa kuti apereke satifiketi yotsimikizira momwe granite ilili. Wopanga wodalirika adzapereka zikalatazi mosavuta. Wogulitsa aliyense amene sangathe kapena sadzatsimikizira kapangidwe kake ayenera kuonedwa mokayikira.
Kusankha Kukula: Kupeza Malo Ogwirira Ntchito Oyenera
Mapepala opangidwa pamwamba amabwera m'mitundu yosiyanasiyana, kuyambira ma mbale ang'onoang'ono a labu a 300mm × 200mm mpaka ma mbale akuluakulu opitirira 3,000mm m'litali. Malo ogwirira ntchito ayenera kukhala ndi kukula kokwanira kuti agwirizane ndi chogwirira ntchito chachikulu kwambiri kapena chogwirira ntchito chomwe chidzayikidwapo, ndikusiya malire okwanira othandizira ndi kupeza.
Magulu ofanana kukula ndi awa:
- · Yaing'ono (mpaka 600mm): Zigawo zamagetsi, zida zolondola, zigawo zazing'ono zamakanika
- · Wapakati (600mm mpaka 1,500mm): Kuyang'anira zida, zida zogwiritsidwa ntchito ndi makina apakatikati, maziko a CMM
- · Lalikulu (1,500mm mpaka 3,000mm+): Zigawo zazikulu zopangidwa, makina osonkhanitsira zida, zida zoyendera ndege
Opanga ena amatha kupanga kukula koyenera. Pa ntchito zomwe zimafuna mbale zopitirira 3,000mm, ndikofunikira kutsimikizira kuti wogulitsa ali ndi luso lopanga komanso zida zapadera zopera kuti akwaniritse kusalala komwe kwatchulidwa pamalo onse ogwirira ntchito.
Zofunika Kuganizira: Maimidwe, Mizere, ndi Mapedestal
Chidebe chapamwamba chimakhala chokhazikika ngati makina ake othandizira. Ma stendi olimba kapena opindika okhala ndi mapazi osinthika amalola kuti chidebecho chikhale chofanana bwino ndipo chingakhale ndi zinthu zochepetsera kugwedezeka kuti chigwiritsidwe ntchito m'malo opangira mafakitale. Ma stendi ayenera kuyikidwa pamalo omwe amalangizidwa ndi wopanga chidebecho kuti apewe kusokonekera kwa malo ogwirira ntchito.
Mizere ya granite ndi mbale zopingasa kumanja ndi zinthu zogwiritsidwa ntchito kwambiri pamodzi ndi mbale zapamwamba poika mizere yolozera pazidutswa zogwirira ntchito zamitundu itatu. Ma seti a granite ofanana amagwiritsidwa ntchito poyang'ana kuzungulira, kukhazikika, ndi kufanana kwa zigawo zozungulira.
Kusankha kwa Ogulitsa: Kodi Mainjiniya Abwino Amaonadi Chiyani?
Pofufuza omwe amapereka mapepala apamwamba, mainjiniya odziwa bwino ntchito nthawi zambiri amafufuza zinthu zingapo:
1. Miyezo ya satifiketi — Tsimikizirani kuti wogulitsa akhoza kupereka mbale zotsimikizika ku muyezo womwe ukufunika (ASTM, DIN, ISO, JIS, ndi zina zotero)
2. Kulondola — Muyeso wa kusalala uyenera kutsatira miyezo ya dziko kapena yapadziko lonse lapansi ya metrology
3. Zolemba za zinthu — Umboni wa kuchuluka kwa granite ndi kapangidwe ka mchere
4. Luso lopanga — Onetsetsani kuti wogulitsa ali ndi zida ndi ukadaulo wa kukula ndi mtundu wofunikira
5. Ntchito zokonzanso certification — Kutsimikizira kosalekeza kwa flatness, kaya mkati mwa kampani kapena kudzera mu labotale yovomerezeka yowunikira
Malo omwe akhala akugwira ntchito ndi ogulitsa mapepala apamwamba kwa zaka zambiri amanena kuti njira yoyezera ya ogulitsayo ndi yofunika kwambiri monga momwe mbaleyo imagwirira ntchito. Wopanga yemwe amagwiritsa ntchito njira zoyezera za interferometry ndi laser adzapeza zotsatira zofanana kuposa amene amadalira njira zosavuta.
Kukonza ndi Kukonzanso Chikalata
Ngakhale mbale yapamwamba kwambiri imafunika kubwezeretsanso nthawi ndi nthawi kuti itsimikizire kuti kusalala kwake sikunasunthe. Kuchuluka kwa kusweka kumadalira mphamvu yogwiritsidwa ntchito komanso kuchuluka kwa kusalala komwe kumafunikira. M'mafakitale ambiri, kubwezeretsanso chaka ndi chaka ndi njira yodziwika bwino ya mbale za Giredi 0 ndi Giredi 1, ndipo nthawi zambiri amafufuza mbale za Giredi 00 zomwe zimagwiritsidwa ntchito m'ma laboratories oyesera.
Kukonzanso kumaphatikizapo kuyeza pamwamba pa malo osiyanasiyana pogwiritsa ntchito ma autocollimators, ma level amagetsi, kapena ma laser interferometers, kenako kuwerengera kupotoka kwa flatness poyerekeza ndi muyezo woyenera. Mbale iliyonse yomwe imapitirira grade yake yolekerera iyenera kuchotsedwa pa ntchito kapena kukonzedwanso ndi katswiri wodziwa bwino ntchito yopera.
Mafunso Ofunsidwa Kawirikawiri
Kodi pali kusiyana kotani pakati pa mapepala apamwamba a Giredi 00, Giredi 0, ndi Giredi 1?
Giredi 00 ili ndi kupirira kolimba kwambiri kwa kusalala (≤0.5 μm/m), Giredi 0 imalola ≤1 μm/m, ndipo Giredi 1 imalola ≤2 μm/m. Sankhani Giredi 00 kuti mugwiritse ntchito poyesa, Giredi 0 kuti muyang'anire zonse, ndi Giredi 1 kuti mugwiritse ntchito pa msonkhano.
Kodi mbale ya pamwamba pa granite imatenga nthawi yayitali bwanji?
Ndi chithandizo choyenera komanso kubwezeretsanso nthawi ndi nthawi, granite pamwamba pake imatha kugwira ntchito kwa zaka 30 kapena kuposerapo. Cholepheretsa nthawi zambiri si kuwonongeka koma kusintha kwa kusalala komwe sikungatheke kwa nthawi yayitali.
Kodi ma granite pamwamba pake angakonzedwenso ngati atasiya kusalala?
Inde. Kukonzanso (kupukutanso) kumatha kubwezeretsa mbale pamwamba pa pulasitiki kuti ikhale yolimba, bola mbaleyo ili ndi zinthu zokwanira zotsala. Opanga ambiri angapereke chithandizochi.
N’chifukwa chiyani ogulitsa ena amapereka mapepala apamwamba pamitengo yotsika kwambiri?
Mitengo yotsika nthawi zambiri imasonyeza kugwiritsa ntchito zipangizo zosalimba za granite (monga marble kapena granite yotsika), njira zopangira zosalondola kwenikweni, kapena kutsimikizira kuti ndi yosalala kwambiri. Ndalama zoyambira zomwe zasungidwa zitha kuchepetsedwa ndi zosowa zokonzanso msanga kapena kusinthidwa kwathunthu.
Ndi zinthu ziti zofunika pa mbale yopangira pamwamba?
Choyimira choyenera chokhala ndi mapazi olinganiza n'chofunikira. Zowonjezera zomwe mungasankhe zikuphatikizapo miyala ya granite, mbale zolunjika kumanja, ma seti ofanana, ndi kuchuluka kwa mzimu. Kuwunika kutentha ndi chinyezi kumalimbikitsidwa kuti mugwiritse ntchito molondola kwambiri.
