Isiseko segranite asiyonto nje iphambili; sisizinzisi esisisiseko se-metrology echanekileyo kakhulu, izixhobo zoomatshini, kunye neenkqubo ze-optical eziphambili. Ekhethwe ngenxa yokuzinza kwayo okungokwemvelo, ubulukhuni obuphezulu, kunye nokwandiswa kobushushu obuphantsi kakhulu, isiseko segranite esichanekileyo, ngakumbi eso senziwe nge-high-density ZHHIMG® Black Granite (≈3100 kg/m³), siqinisekisa ukuba ukuchaneka kwinqanaba le-nanometer kuyafezekiswa kwaye kuyaqhubeka. Nangona kunjalo, nesiseko esizinzileyo kakhulu sifuna unonophelo olunzulu kunye nokunamathela kwiindlela ezingqongqo zokugcina ukusebenza kwaso okuqinisekisiweyo kubomi baso obude.
Ukufezekisa ukuchaneka okuhlala ixesha elide kuqala ngokufakela kunye nolawulo lokusingqongileyo. Iqonga apho isiseko segranite simi khona kufuneka siqine ngokugqibeleleyo, sibe kumgangatho othe tyaba, kwaye singabi namanqaku oxinzelelo akwindawo ethile. Nakuphi na ukungalingani okanye ukungazinzi kwisiseko kunokubangela uxinzelelo olungafaniyo kwigranite, okonakalisa ukuthamba kwayo kunye nozinzo—into esiyinciphisa ngononophelo kwiiholo zethu zokuhlanganisa ezilawulwayo ezingama-10,000 m². Ngaphezu koko, imeko-bume ngokwayo kufuneka ilawulwe. Ukuvezwa kumswakama ogqithisileyo kunokukhokelela ekwandeni kwe-hygroscopic ngaphakathi kwesakhiwo selitye, okunokubangela ukuguquka, ngelixa ukusondela kwimithombo yobushushu okanye amasimi anamandla e-electromagnetic kunokungazinzisi izixhobo ezifakwe kwisiseko. Ukusebenza kakuhle kufuna indawo eyomileyo, enomoya ococekileyo kunye nokuguquguquka okuncinci kobushushu.
Ngexesha lokusebenza kwemihla ngemihla, ukuphathwa ngokuqaphela kubaluleke kakhulu. Iziseko zegranite zenzelwe ukuzinza okungaguqukiyo nokuguqukayo phantsi kwemithwalo yazo elinganisiweyo, kodwa azithintelwa kukusetyenziswa gwenxa. Abaqhubi kufuneka banamathele ngokungqongqo kumda womthwalo ochaziweyo wesiseko, baqinisekise ukuba ubunzima busasazwa ngokulinganayo ukuthintela ukugoba kwendawo okanye ukwaphuka koxinzelelo okunokubeka emngciphekweni izixhobo ezifakiweyo. Ukuwisa izixhobo, iimpembelelo ezibukhali, okanye ukubeka izinto ezinzima emaphethelweni kunokubangela umonakalo ongenakulungiswa kwi-geometry yomphezulu ocociweyo kakhulu. Ukuba isiseko esikhulu segranite kufuneka sifuduselwe kwenye indawo, kufuneka kusetyenziswe izixhobo ezikhethekileyo kuphela, ezilinganiswe umthwalo, zisenza intshukumo kancinci kwaye ngabom ukuze kuthintelwe ukothuka. Emva kokufuduswa, inkqubo yokuhlaziya ngokupheleleyo kunye nokulinganisa iyimfuneko ukubuyisela uzinzo lwesiseko sesiseko.
Indlela yokulungisa nokucoca kufuneka ibe chanekileyo ukuze kukhuselwe umphezulu olinganisiweyo. Ukucoca uthuli rhoqo kufuneka kuquke kuphela ilaphu elithambileyo nelomileyo. Okubalulekileyo kukuba, kuphela izinto zokucoca ezingathathi cala, ezingaboliyo—ezenzelwe ngokukodwa i-granite—ezimele zisetyenziswe ukususa iintsalela eziqinileyo. Izinto ezi-asidi okanye ze-alkaline zinokugrumba umphezulu ocoliweyo kakhulu, zitshabalalise ukugqitywa okuchanekileyo. Ngaphezu koko, ukhuseleko kumonakalo womzimba lubalulekile; izixhobo zesinyithi, ii-probes, okanye izinto zokusebenza akufuneki zirhuqwe kumphezulu. Kwiindawo ezisetyenziswa kakhulu okanye ezibekwa rhoqo kwiindawo, ukusebenzisa ii-cushioning pads ezingaboliyo yindlela elula kodwa esebenzayo yokuthintela ukukrweleka okuncinci, ukuqinisekisa ukuba isiseko sigcina ukuthembeka okufunekayo kwisiqinisekiso seBanga 00/0.
Okokugqibela, ukuthembeka kwexesha elide kwesiseko segranite kuxhomekeke kwishedyuli yokulinganisa enzima. Nangona ukuzinza kwegranite kungaphezulu kunentsimbi, ukuchaneka komphezulu kuyawohloka kancinci kancinci ngenxa yokuguga okuqhelekileyo kunye notshintsho oluncinci lokusingqongileyo. Ngokuxhomekeke kubukhali bokusetyenziswa kunye nomgangatho wokuchaneka ofunekayo, uhlolo lwamaxesha athile—ngokuvamile ukusuka kwikota ukuya kunyaka ngamnye—kufuneka lwenziwe ziingcali zemetrology eziqinisekisiweyo zisebenzisa izixhobo ezichanekileyo kakhulu, ezifana neRenishaw Laser Interferometers okanye iiWYLER Electronic Levels. Iirekhodi ezipheleleyo zale mihla yokulinganisa, idatha, kunye nezenzo zokulungisa zibalulekile ekugcineni ukulandeleka kwesiseko kunye nokuqinisekisa ukufaneleka kwaso okuqhubekayo kwimisebenzi echanekileyo kakhulu esixhasayo. Ngokulandela ezi nkqubo zokusebenza zingqongqo, abasebenzisi banokusebenzisa ngokupheleleyo uzinzo lweZHHIMG® Granite Base, beqinisekisa ukuba ukuzinikela kwabo ekuchanekeni kuhlala kuhleli.
