Izinto zegranite zidlala indima ebalulekileyo kwimveliso yanamhlanje yemizi-mveliso kunye ne-metrology yelebhu. Njengeendawo ezisisiseko zokubhekisa, zisetyenziselwa ukulinganisa ngokuchanekileyo, ukulungelelanisa, ukuhlanganisa oomatshini, kunye nokuhlolwa komgangatho. Uzinzo lwazo, ukumelana nokugqwala, kunye neempawu ezingezizo zemagnethi zenza igranite esemgangathweni ophezulu ibe yinto efanelekileyo yezixhobo, iziseko zoomatshini, kunye nezixhobo ezichanekileyo. Ukuqinisekisa ukuchaneka kwexesha elide, izakhiwo zegranite kufuneka zifakwe ngokuchanekileyo kwaye zibuyiselwe rhoqo xa kusenzeka ukuguguleka, ukukrweleka, okanye umonakalo ngengozi. Ukuqonda inkqubo yokulungisa kunceda ukwandisa ubomi benkonzo kunye nokugcina ukuthembeka kwezixhobo ezibalulekileyo.
Ukufakelwa ngokufanelekileyo sisiseko sokuchaneka kwenxalenye yegranite. Ngexesha lokuseta, iingcali zihlala zisebenzisa amanqanaba e-elektroniki okanye esakhelo ukulungelelanisa umphezulu wokusebenza. Iibholithi ezixhasayo kwi-granite stand zilungiswa ukuze kufezekiswe uzinzo oluthe tye, ngelixa i-stand ngokwayo idla ngokudityaniswa kwi-reinforced square tube ukunciphisa ukungcangcazela ngexesha lokusetyenziswa. Emva kokuba iqonga liphakanyisiwe ngononophelo kwaye libekwe kwi-stand, iinyawo ezilinganayo ezingaphantsi kwesakhelo ziyalungiswa kakuhle ukuqinisekisa ukuba yonke indibano ihlala izinzile kwaye ingenantshukumo. Nakuphi na ukungazinzi kweli nqanaba kuya kuchaphazela ngqo ukusebenza kokulinganisa.
Ekuhambeni kwexesha, negranite ekumgangatho ophezulu ingabonakalisa ukuguguleka okuncinci okanye ilahlekelwe bubucaba ngenxa yokusetyenziswa kakhulu, ukusasazwa komthwalo okungafanelekanga, okanye iziphumo zokusingqongileyo. Xa oku kusenzeka, ukubuyiselwa kobungcali kubalulekile ukubuyisela inxalenye kwinqanaba layo lokuchaneka lokuqala. Inkqubo yokulungisa ilandela ulandelelwano lwamanyathelo okulawula umatshini kunye nokutsalwa ngesandla. Inqanaba lokuqala kukugaywa okurhabaxa, okususa ukuguquka komphezulu kwaye kumise kwakhona ubukhulu obufanayo kunye nobucaba bokuqala. Eli nyathelo lilungiselela ilitye imisebenzi echanekileyo ngakumbi.
Nje ukuba umphezulu ulungiswe ngokusila okurhabaxa, iingcali ziqala ukusila okuncinci ukuze zisuse imikrwelo enzulu kwaye ziphucule ijiyometri. Eli nqanaba libalulekile ekufezekiseni isiseko esizinzileyo nesizinzileyo ngaphambi kokungena kwizigaba zokugqibela zokuchaneka-ezibalulekileyo. Emva kokusila okuncinci, igranite irhangqwa ngesandla kusetyenziswa izixhobo ezikhethekileyo kunye ne-abrasives ezintle kakhulu. Iingcali zezandla—ezininzi ezinamava eminyaka emininzi—zenza lo msebenzi ngesandla, zizisa umphezulu ngokuthe ngcembe ngokuchanekileyo okufunekayo. Kwizicelo zokuchaneka okuphezulu, inkqubo inokuphindwa amaxesha amaninzi ukuze kufezekiswe i-micrometer okanye i-sub-micrometer flatness.
Xa kufikelele ekuchanekeni okufunekayo kokulinganisa, umphezulu wegranite uyapholishwa. Ukupholishwa kuphucula ukuguda komphezulu, kunciphisa amaxabiso oburhabaxa, kuphucula ukumelana nokuguguleka, kwaye kuqinisekisa uzinzo lwexesha elide. Ekupheleni kwenkqubo, inxalenye iyacocwa ngononophelo, ihlolwe, kwaye ihlolwe ngokwemigangatho yamazwe ngamazwe. Umphezulu wegranite ofanelekileyo kufuneka ungabi naziphene ezifana nemingxunya, imifantu, ukugquma, imikrwelo, okanye naziphi na iziphene ezinokuchaphazela ukusebenza. Yonke inxalenye egqityiweyo ivavanywa ngokwemetrological ukuqinisekisa ukuthotyelwa komgangatho ofunekayo.
Ukongeza ekubuyiselweni, izinto zegranite ngokwazo zivavanyelwa ngokungqongqo kwilebhu ngaphambi kokuba ziqale ukuvelisa. Iinkqubo zovavanyo zihlala ziquka uvavanyo lokumelana nokuguguleka, ukujonga uzinzo lobukhulu, ukulinganiswa kobunzima kunye noxinano, kunye nohlalutyo lokufunxwa kwamanzi. Iisampulu ziyacolwa, zisikwe ngokwemilinganiselo eqhelekileyo, kwaye zivavanywe phantsi kweemeko ezilawulwayo. Zilinganiswa ngaphambi nasemva kwemijikelo yokurhawuzelela, zifakwe emanzini ukulinganisa ukugcwala, kwaye zomiswe kwiindawo ezinobushushu obungaguqukiyo okanye ezingenanto kuxhomekeke ekubeni ilitye legranite yendalo okanye ilitye elenziweyo. Ezi mvavanyo ziqinisekisa ukuba izinto ziyahlangabezana neemfuno zokuqina kunye nozinzo ezilindelekileyo kubunjineli bokuchaneka.
Izinto zegranite, nokuba zisetyenziswa kwiilebhu zemetrology okanye koomatshini abaphambili bemizi-mveliso, zihlala zibalulekile kwiindawo ezifuna indawo ezinzileyo yokubhekisa. Ngokufakelwa ngokufanelekileyo, uhlolo oluqhelekileyo, kunye nokulungiswa kobuchwephesha, amaqonga kunye nezakhiwo zegranite zinokugcina ukuchaneka kwazo iminyaka emininzi. Iingenelo zazo ezisisiseko—ukuzinza okulinganayo, ukumelana nokugqwala, kunye nokuthembeka kwexesha elide—zenza zibe zizixhobo ezibalulekileyo ekuveliseni ngokuchanekileyo, uphando lwesayensi, kunye neendawo zemveliso ezenzekelayo.
