Mu dziko lolondola kwambiri la metrology ndi kupanga, granite pamwamba pa mbale kapena gawo loyezera nthawi zambiri limaonedwa ngati chinthu chosasunthika—umboni wosakhazikika, wosasunthika wosonyeza kudutsa kwa zigawo ndi zigawo zambiri. Chifukwa cha kulemera kwake kwakukulu ndi chiyambi chake chachilengedwe, pali lingaliro lolakwika lofala lakuti granite ndi yosawonongeka. Komabe, aliyense amene wagwira ntchito m'malo a Giredi 00 amadziwa zoona zake: granite yolondola ndi chida chasayansi chapamwamba. Kuti isunge kulondola kwake kwa sub-micron, imafuna chisamaliro ndi chisamaliro chofanana ndi kulondola komwe imapereka.
Kunyalanyaza zida zanu za granite sikuti kumangoyambitsa kuwonongeka kwa thupi; kumabweretsa "kusinthasintha kwa muyeso," chinthu chobisika koma choopsa chomwe maziko anu a "zero" amasintha pang'onopang'ono pakapita nthawi. Bukuli likufotokoza njira zofunika kwambiri zosungira umphumphu wa zinthu zanu za granite, ndikuwonetsetsa kuti zikukhalabe maziko odalirika a kuwongolera khalidwe lanu kwa zaka zambiri zikubwerazi.
Ndondomeko ya Ukhondo: Kupitirira Fumbi la Pamwamba
Choopsa chachikulu pa granite pamwamba pa mbale si chinthu cholemera chogwirira ntchito, koma tinthu tating'onoting'ono tomwe timakhala pamwamba pake. Udzu wouluka, zitsulo zodulidwa kuchokera ku makina oyandikana nawo, komanso mafuta achilengedwe ochokera pakhungu la katswiri amagwira ntchito ngati zotsukira zamafakitale. Chidutswa chikasunthidwa pa mbale yodetsedwa, tinthuti timaphwanyidwa mumwala, kuchita ngati sandpaper yomwe imadutsa pang'onopang'ono pamwamba pake pomalizidwa bwino.
Kuyeretsa bwino n'kofunika tsiku ndi tsiku. Komabe, kusankha chotsukira n'kofunika kwambiri. Muyenera kupewa zotsukira zapakhomo zomwe zili ndi sera, ma polish, kapena mankhwala amphamvu a asidi. Izi zimatha kusiya filimu pamwala yomwe imasintha kutalika kwa muyeso wanu kapena, choipa kwambiri, kuukira ndi mankhwala zomangira zomwe zimagwirira kapangidwe ka kristalo ka granite pamodzi.
Muyezo wa makampani ndi woyeretsera granite wopangidwa ndi madzi. Izi zimapangidwa kuti zinyamule dothi ndi mafuta pamwamba pomwe zitha kuchotsedwa popanda kusiya zotsalira. Njirayi ndi yosavuta koma iyenera kutsatiridwa:
-
Ikani chotsukiracho momasuka pamwamba pake.
-
Lolani kuti likhalepo kwa kanthawi kuti lipangitse mafuta aliwonse omwe ali m'mabokosiwo kusungunuka.
-
Pukutani pamwamba pake pogwiritsa ntchito nsalu yoyera, yopanda ulusi.
-
"Mayeso a Dzanja": Mukauma, tsitsani dzanja lanu pamwamba. Liyenera kumveka losalala komanso losalimba. Ngati likuwoneka "losagwira" kapena "losagwira," filimuyo ikadalipo, ndipo njira yoyeretsera iyenera kubwerezedwa.
Kusamalira Malo Otentha
Ngakhale granite ndi yotchuka chifukwa cha kuchuluka kwake kochepa kwa kutentha poyerekeza ndi zitsulo monga chitsulo kapena aluminiyamu, siili yotetezeka ku malamulo a sayansi ya zakuthambo. Chimodzi mwa zinthu zomwe zimanyalanyazidwa kwambiri pakusamalira ndi kukhazikika kwa kutentha.
Granite ndi chowongolera kutentha chofooka. Izi zikutanthauza kuti ngati mbali imodzi yambale ya pamwambaKufunda kuposa kwina—mwina chifukwa cha mpweya wozizira womwe uli pafupi, kuwala kwa dzuwa kuchokera pawindo, kapena ngakhale gawo lotentha lomwe lachotsedwa posachedwa pa makina a CNC—mwalawo udzakhala ndi “kutentha.” Mbali yofundayo idzakula pamene mbali yozizirayo idzakhalabe yokhazikika, zomwe zimapangitsa kuti mwalawo ugwedezeke kapena kupindika pang'ono.
Kuti zikhale zolondola kwambiri, zida zanu za granite ziyenera kusungidwa pamalo otetezedwa ndi kutentha, makamaka pa 20℃ (68℉). Ngati mbale yasamutsidwa kuchokera ku doko lotumizira katundu kupita ku labu, imafunika "nthawi yonyowa" - nthawi zambiri maola 24 mpaka 48 - kuti ifike pamlingo wofanana ndi kutentha musanayambe kuyeza molondola kwambiri. Kusamalira motere kumatanthauza kuteteza chidacho ku kusintha kwadzidzidzi kwa nyengo ya chipindacho.
Kupewa Kuwonongeka Kwathupi: Kukweza ndi Kuzungulira
Ngakhale granite wakuda wolimba kwambiri amatha kudulidwa kapena kukanda ngati atagwiritsidwa ntchito molakwika. Cholakwika chofala kwambiri ndi "kukoka" ziwalo pa mbale kuchokera m'mphepete. Izi zingayambitse kudulidwa pamphepete, zomwe pamapeto pake zimatha kusunthira pakati. Zigawo ziyenera kutsitsidwa pang'onopang'ono pamwamba. Pazinthu zolemera makamaka, ganizirani kugwiritsa ntchito filimu yopyapyala ya "air bearing" yapadera kapena chokweza chodziyimira pawokha kuti mupewe kugunda.
Chinthu china chothandiza kuti mbale yanu ikhale ndi moyo wautali ndikugwiritsa ntchito pamwamba pake ponse. Akatswiri ambiri ali ndi ngodya yomwe amakonda kwambiri pa mbale pomwe amagwira ntchito 90% ya ntchito zawo. Kwa zaka zingapo, "malo abwino" awa amawonongeka mofulumira kuposa mwala wonse, zomwe zimapangitsa kuti mbaleyo isagwe. Mwa kusinthasintha dala makonzedwe anu ndikugwiritsa ntchito madera osiyanasiyana a mbaleyo, mukuwonetsetsa kuti kusweka kwagawidwa mofanana, zomwe zimachedwetsa kwambiri tsiku lomwe ntchito yanu yotsatira yolumikizirana ichitike.
Kukonzanso ndi Kulumikiza Ma Lapping Mwaukadaulo
Kukonza sikungokhudza zomwe mumachita tsiku ndi tsiku; koma ndi nkhani yolemba thanzi la chidacho. Ma granite pamwamba pake ayenera kuyesedwa mwaukadaulo kamodzi pachaka, kapena mobwerezabwereza ngati agwiritsidwa ntchito popanga zinthu zambiri.
Kulinganiza kumaphatikizapo kugwiritsa ntchito laser interferometer kapena electronic level kuti iwonetse mawonekedwe a pamwamba. Ngati kulinganiza kukuwonetsa kuti mbaleyo ili ndi "zitunda" kapena "zigwa" kunja kwa kulekerera kwake koyenera (monga, Giredi AA, A, kapena B), idzafunika kulumikizidwa ndi manja. Iyi ndi njira yapadera yosamalira komwe katswiri amagwiritsa ntchito mankhwala oletsa diamondi kuti aphwanye malo okwera pamanja mpaka mbaleyo ibwerere ku mawonekedwe ake oyambirira.
Kusunga ndi Kuteteza
Ngati mbaleyo sikugwiritsidwa ntchito, iyenera kuphimbidwa nthawi zonse. Chophimba chosavuta cha vinyl kapena chopangidwa mwapadera chimateteza fumbi louluka kuti lisagwere ndipo chimateteza pamwamba kuti lisagwere mwangozi (monga wrench yomwe yagwa). Kuphatikiza apo, onetsetsani kuti mbaleyo yayikidwa pamakina othandizira a mfundo zitatu. Granite ndi yolemera mokwanira kotero kuti imatha kugwa pansi pa kulemera kwake ngati itathandizidwa molakwika. Kugwiritsa ntchito malo othandizira osankhidwa ndi wopanga kumaonetsetsa kuti mbaleyo ikhale yosalala monga tsiku lomwe idapangidwa.
Mapeto
Zipangizo za granite zolondola kwambiri zimafuna ndalama zambiri kuti zigwiritsidwe ntchito molondola. Mwa kutsatira ndondomeko yokhwima yoyeretsa tsiku ndi tsiku, kuyang'anira kutentha, komanso kugwiritsa ntchito mwanzeru, mutha kupewa kuwonongeka msanga. Kumbukirani: simukungotsuka mwala; mukuteteza "zero point" ya njira yanu yonse yopangira. Kusamalira bwino kumatsimikizira kuti mukanena kuti gawo "liri mkati mwa kulolerana," muli ndi maziko olimba otsimikizira izi.
