Esimweni esingavamile semishini enembile kakhulu, lapho ukubekezelelana kulinganiswa kuma-micron angaphansi futhi ukukhukhuleka kokushisa kuyisitha sekhwalithi, ukukhetha izinto zokwakha akuyona nje into ecatshangelwayo yokuklama—kuyisici esichaza ukusebenza. Njengoba ukukhiqiza kuqhubekela phambili emikhawulweni yefiziksi, ikakhulukazi emikhakheni efana ne-semiconductor lithography, ukugaya ilensi ye-optical, kanye nemishini yokulinganisa ehambisanayo (CMM), indinganiso yemboni igxile kakhulu ku-granite. Kodwa-ke, "i-granite" akuyona i-monolith. Ukukhetha izingxenye ze-granite ezifanele kudinga ukuqonda okuningiliziwe kwe-geology, i-physics, kanye namakhono okukhiqiza athuthukile. Lesi sihloko siqondisa onjiniyela kanye nochwepheshe bokuthenga ngezici ezibalulekile zokukhetha izingxenye ze-granite ezifanele kakhulu zezinhlelo zokusebenza ezinembile kakhulu.
Isisekelo Se-Geological: Akuzona Zonke Itshe Eladalwa Lilingana
Uhambo lokukhetha ingxenye efanele luqala ngaphansi komhlaba. Emishinini enembile kakhulu, indinganiso yemboni cishe i-granite emnyama kuphela, evame ukutholakala ezinhlotsheni ezithile ze-geological ezaziwa ngokusanhlamvu kwayo okuhle kanye nokufana kwayo. Eyaziwa kakhulu kulezi yi-granite ethi “Jinan Green” noma “Jinan Black” etholakala esifundazweni saseShandong eShayina, isifunda esibe yindawo yomhlaba wonke yokukhipha amatshe ekhwalithi ephezulu.
Uma kuhlolwa abaphakeli abangaba khona, umbandela wokuqala kumele kube ukuhlanzeka kwezinto ezibonakalayo. I-granite enembile kakhulu kumele ingabi nemithambo ye-quartz, imifantu, kanye nokungcola okungaholela ekuhlulekeni kwesakhiwo noma ekugugeni okungalingani ngokuhamba kwesikhathi. Izinto ezifanelekile zinesakhiwo esiqinile, esinezinhlayiya ezincane esinobunzima be-Mohs obungaba ngu-6.5 kuya ku-7. Lobu bunzima bubalulekile; buqinisekisa ukuthi ingxenye imelana nokuklwebheka nokuklwebheka ngesikhathi sokusebenza, igcina ubuqotho bayo bejometri amashumi eminyaka. Ngaphezu kwalokho, izinto kumele "zincishiswe ukucindezeleka" ngokwemvelo. Ngokungafani nezinsimbi ezibunjiwe, ezidinga ukuguga kokwenziwa ukuze kususwe ukucindezeleka kwangaphakathi, i-granite yemvelo ibilokhu iguga izigidi zeminyaka, inikeza izinga lokuzinza okulinganayo izinto zokwenziwa ezilwela ukulilingana.
Ukuzinza Kokushisa: I-Anchor Ezweni Elishintshashintshayo
Ezindaweni ezinembe kakhulu, ukushisa kuwumthombo oyinhloko wamaphutha. Njengoba amathuluzi omshini nezinjini kukhiqiza ukushisa, noma njengoba amazinga okushisa efektri eshintsha, izinto ziyanda futhi zincipha. Insimbi, isibonelo, ine-coefficient of thermal expansion (CTE) engaletha amaphutha amakhulu emabangeni amade.
Ingxenye ye-granite efanele isebenza njenge-thermal anchor. I-granite emnyama esezingeni eliphezulu ivame ukubonisa i-CTE ecishe ibe yi-1.5m
4.6×10−6/∘C, okuphansi kakhulu kunensimbi ephonswe noma insimbi. Lokhu kusho ukuthi kuzo zonke izinga lokushintsha kwezinga lokushisa, isakhiwo se-granite sishintsha ubukhulu obuncane kakhulu kunobalingani baso bensimbi. Lapho ukhetha umhlinzeki, kubalulekile ukucela umbiko wempahla ebonakalayo, ikakhulukazi ukufuna i-hygroscopicity ephansi (ukumuncwa kwamanzi) kanye ne-coefficient yokwanda kokushisa eqhubekayo. Lokhu kuqinisekisa ukuthi umshini ugcina ukulinganiswa kwawo ngisho nasezindaweni lapho kunzima khona ukusekela ukulawulwa kwesimo sezulu okuphelele.
Amabanga Okucophelela kanye Nokuqedwa Komphezulu
Uma izinto zokusetshenziswa sezikhethiwe, ingxoxo ishintshela emandleni okucubungula. Izingxenye ze-granite ngokuvamile zihlukaniswa ngamamaki okunemba, ngokuvamile zinamathela ezindinganisweni ezifana ne-DIN 876 noma i-ASME B89.3.7. Emishinini enembile kakhulu—njengesisekelo se-CMM ephezulu noma isigaba sohlelo lokucubungula nge-laser—amamaki aphezulu kakhulu kuphela (amamaki angu-00 noma angu-0) ayamukelekayo.
Ukufinyelela la mabanga kudinga inhlanganisela yobuchwepheshe besimanje kanye nekhono lobuciko. Inqubo yokukhiqiza ivame ukuqala ngokusika idayimane elikhulu kanye nokugaya i-CNC ukuze kufezwe i-geometry eqinile. Kodwa-ke, ukuqeda kokugcina kobuso kanye nokuba bushelelezi kuvame ukufezwa ngokufaka isandla. Yilapho ubuchwepheshe bomenzi buba khona obubalulekile. Izingcweti ezingochwepheshe zisebenzisa imiphetho eqondile kanye namathuluzi asezingeni likagesi ukuze ziklwebhe futhi zipholishe itshe, zisuse izindawo eziphakeme ezincane ukuze kufezwe ukubekezelelana kokuba bushelelezi okungaphansi kwe-micron eyodwa ngemitha.
Uma ukhetha umlingani, funa abakhiqizi abanamakhono e-CNC anzima okulungisa i-roughing kanye nendawo "ehlanzekile" ezinikele ezigabeni zokugcina zokuqeda. Ukushintshashintsha kothuli kanye nokushisa ngesikhathi senqubo yokugcina yokubopha kungonakalisa ukunemba kwengxenye, ngakho-ke indawo elawulwayo ayinakuxoxiswana ngayo.
Ukwenza Ngokwezifiso Nokuhlanganiswa: Ngale Kwepuleti Eliyisicaba
Sezadlula izinsuku lapho i-granite yayisetshenziswa kuphela njengetafula lokuhlola eliyisicaba. Imishini yesimanje enembile kakhulu idinga izakhiwo eziyinkimbinkimbi ze-3D—amabhuloho ashukumisayo, ama-gantries, namatafula ajikelezayo. Lokhu kudinga umenzi okwaziyo ukucubungula ngokujulile.
Ingxenye efanele ye-granite izoba nezingcezu zensimbi ezifakiwe zokufaka iziqondiso eziqondile, izimbobo ezinezintambo zokuhlanganisa, kanye nezingcezu ze-T zokuhlanganisa. Inqubo yokufaka lezi zinto zensimbi etsheni iyindlela yobuciko ngokwayo. Ihilela ukubhoboza izimbobo eziqondile, ukubopha izingcezu ezinezintambo zensimbi engagqwali noma zethusi nge-epoxy enamandla aphezulu, nokuqinisekisa ukuthi isibopho asidali ukucindezeleka kwangaphakathi okungase kugobe itshe.
Ngaphezu kwalokho, abakhiqizi abathuthukile manje basebenzisa amasu okubumba amaminerali (i-granite yokwenziwa) kanye netshe lemvelo. Lokhu kuhilela ukuxuba i-granite echotshoziwe nama-resin epoxy ukuze kubumbanwe izimo eziyinkimbinkimbi okungenzeka kube nzima ukuzisebenzisa kusukela kubhlokhi eliqinile. Lapho uhlola abahlinzeki, cabanga ngekhono labo lokunikeza izixazululo "ezihlanganisiwe" - besebenzisa i-granite yemvelo ezindaweni ezibalulekile zokubhekisela kanye nokubumba amaminerali ngobukhulu besakhiwo, okwenza kube ngcono kokubili izindleko kanye nokusebenza.
Ukubaluleka kwe-Metrology kanye ne-Certification
Ezweni lokunemba okukhulu, ukwethenjwa kumele kuqinisekiswe. Umhlinzeki we-granite othembekile ngeke athumele ingxenye nje; uzohlinzeka "ngesitifiketi sokuzalwa" esiphelele sengxenye. Le mibhalo kufanele ifake umbiko wokuhlola onemininingwane owenziwe yi-laser interferometers noma ama-autocollimator kagesi.
Le mibiko idweba ubuso be-granite, inikeza imephu ye-contour yeziqongo nezigodi kuyo yonke indawo yokusebenza. Ukuze uthole izinhlelo zokusebenza ezinembe kakhulu, kufanele ufune umbiko oqinisekisa ukuthi indawo yonke iphansi, hhayi nje ezindaweni ezimbalwa zesampula. Ngaphezu kwalokho, umhlinzeki kufanele aqinisekiswe yi-ISO 9001, aqinisekise ukuthi uhlelo lwakhe lokuphatha ikhwalithi luqinile ngokwanele ukubhekana nezidingo ezinzima zezimboni zezindiza, zezokwelapha, noma ze-semiconductor.
Isiphetho: Ubambiswano Ekuqondeni Okunembile
Ukukhetha izingxenye ze-granite ezifanele akuyona into yokuthengiselana; kuwukubambisana. Kudinga ukuthola umhlinzeki oqondayo ukuthi abagcini nje ngokusika amatshe, kodwa bakha isisekelo sokunemba komshini wakho. Kusukela ezinkwalini zaseJinan kuya ezindaweni zokusebenzela zobuchwepheshe obuphezulu, isinyathelo ngasinye senqubo sinikeza isandla ekusebenzeni kokugcina kwemishini.
Ngokubeka phambili ubumsulwa bezinto ezibonakalayo, ukuzinza kokushisa, ukukala ngokunembile, kanye nezinqubo zokukhiqiza eziqinisekisiwe, onjiniyela bangaqinisekisa ukuthi imishini yabo enembile kakhulu imi esisekelweni esizinzile kakhulu. Embonini echazwa ngokunembile, i-granite enembile kakhulu ihlala iyisisekelo sekhwalithi.
