Amalungu egranite adlala indima ebalulekileyo kwimveliso yanamhlanje yemizi-mveliso kunye ne-metrology yelabhoratri. Njengesiseko somphezulu wesalathiso, zisetyenziselwa ukulinganisa ngokuchanekileyo, ukulungelelaniswa, ukudibanisa koomatshini, kunye nokuhlolwa komgangatho. Ukuzinza kwabo, ukuxhathisa ukubola, kunye neepropathi ezingeyomagnetic zenza umgangatho ophezulu wegranite ube yinto efanelekileyo yezixhobo, iziseko zoomatshini kunye nezixhobo ezichanekileyo. Ukuqinisekisa ukuchaneka kwexesha elide, izakhiwo ze-granite kufuneka zifakwe ngokuchanekileyo kwaye zibuyiselwe ngamaxesha xa ukugqoka, ukukrazula, okanye ukulimala ngengozi kwenzeka. Ukuqonda inkqubo yokulungisa kunceda ukwandisa ubomi benkonzo kunye nokugcina ukuthembeka kwezixhobo ezibalulekileyo.
Ukufakwa ngokufanelekileyo kusisiseko sokuchaneka kwecandelo legranite. Ngexesha lokuseta, amagcisa asebenzisa amanqanaba ombane okanye isakhelo ukulungelelanisa indawo yokusebenza. Iibholiti ezixhasayo kwi-stand yegranite zihlengahlengiswa ukuze zifikelele uzinzo oluthe tyaba, ngelixa isitendi ngokwaso siqhele ukudityaniswa ukusuka kwityhubhu yesikwere esomeleziweyo ukuze kuncitshiswe ukungcangcazela ngexesha lokusetyenziswa. Emva kokuba iqonga liphakanyiswe ngokucophelela kwaye libekwe kwindawo yokumisa, iinyawo zokulinganisa ngaphantsi kwesakhelo zilungiswe kakuhle ukuqinisekisa ukuba yonke indibano ihlala izinzile kwaye ikhululekile ekuhambeni. Nakuphi na ukungazinzi kwesi sigaba kuya kuchaphazela ngokuthe ngqo ukusebenza komlinganiselo.
Ngokuhamba kwexesha, nokuba i-granite ephezulu ingabonisa ukunxiba okuncinci okanye ukulahlekelwa yi-flatness ngenxa yokusetyenziswa kakhulu, ukuhanjiswa komthwalo okungafanelekanga, okanye imiphumo yokusingqongileyo. Xa oku kusenzeka, ukubuyisela kubuchwephesha kubalulekile ukubuyisela icandelo kwinqanaba lalo lokuchaneka kwasekuqaleni. Inkqubo yokulungisa ilandela ukulandelelana komatshini olawulwayo kunye namanyathelo okubopha ngesandla. Inqanaba lokuqala lisila elirhabaxa, elisusa ukuguqulwa komphezulu kwaye liphinde limisele ubukhulu obufanayo kunye ne-flatness yokuqala. Eli nyathelo lilungiselela ilitye kwimisebenzi echanekileyo.
Emva kokuba umphezulu ulungisiwe ngokusila okurhabaxa, amagcisa aqala ukucola ukuphelisa imikrwelo enzulu kunye nokucokisa ijometri. Eli nqanaba libalulekile ekufezekiseni isiseko esingaguqukiyo nesizinzileyo ngaphambi kokungena kwinqanaba lokugqibela lokuchaneka-ezibalulekileyo. Emva kokusila kancinci, igranite ifakwa ngesandla kusetyenziswa izixhobo ezikhethekileyo kunye neziqhushumbisi ezintle kakhulu. Amachule amachule—abaninzi abanamava angamashumi eminyaka—awenza ngesandla lo msebenzi, ngokuthe ngcembe ewuphucula umgangatho wawo. Kwizicelo zokuchaneka okuphezulu, inkqubo inokuphinda iphindwe kaninzi ukufezekisa i-micrometer okanye i-sub-micrometer flatness.
Xa ukuchaneka komlinganiselo ofunekayo kuye kwafikelelwa, indawo yegranite ipholishiwe. Ukupholisha kuphucula ukugudiswa komphezulu, kunciphisa amaxabiso arhabaxa, kuphucula ukuxhathisa kokunxiba, kunye nokuqinisekisa ukuzinza kwexesha elide. Ekupheleni kwenkqubo, icandelo licocwa ngononophelo, lihlolwe, lize lihlolwe ngokwemigangatho yamazwe ngamazwe. Umphezulu wegranite ofanelekileyo kufuneka ungabinaziphene ezinje ngemingxuma, iintanda, irust inclusions, imikrwelo, okanye naziphi na iziphene ezinokuchaphazela ukusebenza. Icandelwana ngalinye eligqityiweyo livavanywa ngemitha ukuqinisekisa ukuthotyelwa kwebakala elifunekayo.
Ukongeza kubuyiselo, izixhobo zegranite ngokwazo zivavanywa ngokungqongqo kwilebhu ngaphambi kokungena kwimveliso. Iinkqubo zovavanyo ngokuqhelekileyo ziquka uvandlakanyo lokunganyangeki, ukuhlolwa kozinzo lwe-dimensional, ubunzima kunye nomlinganiselo woxinaniso, kunye nohlalutyo lokufunxa kwamanzi. Iisampulu zikhazimlisiwe, zisikwe kwimilinganiselo eqhelekileyo, kwaye zivavanywe phantsi kweemeko ezilawulwayo. Ziye zilinganiswe phambi nasemva kwemijikelo yokurhawuka, zintywiliselwe emanzini ukulinganisa ukugcwala, kwaye zomiswe nokuba kubushushu obungaguqukiyo okanye kwindawo yokufunxa ngokuxhomekeke ekubeni ilitye yigranite yendalo okanye ilitye elenziweyo. Ezi mvavanyo ziqinisekisa ukuba imathiriyeli iyahlangabezana nokuqina kunye neemfuno zozinzo ezilindelwe kubunjineli obuchanekileyo.
Amalungu egranite, nokuba asetyenziswa kwiilebhu ze-metrology okanye koomatshini bemizi-mveliso abaphambili, ahlala ebaluleke kakhulu kwiinkalo ezifuna imiphezulu yesalathiso ezinzileyo. Ngokufakela okufanelekileyo, ukuhlolwa rhoqo, kunye nokubuyiselwa kobugcisa, amaqonga egranite kunye nezakhiwo zinokugcina ukuchaneka kwazo iminyaka emininzi. Izibonelelo zabo zendalo-ukuzinza komda, ukuxhathisa ukubola, kunye nokuthembeka kwexesha elide-kubenza izixhobo ezibalulekileyo kwimveliso echanekileyo, uphando lwezenzululwazi, kunye neendawo ezizenzekelayo zemveliso.
