I-Granite lukhetho oludumileyo lwezinto ezisetyenziswa kwi-bridge CMM (Coordinate Measuring Machine) ngenxa yokuzinza kwayo okuhle, ukuqina kwayo, kunye nokumelana nokuguguleka kwayo. Nangona kunjalo, ayizizo zonke izinto ze-granite ezifanayo, kwaye ukukhetha efanelekileyo ngokweemfuno zokwenyani ze-bridge CMM kubalulekile ekufezekiseni imilinganiselo echanekileyo nethembekileyo. Nazi ezinye izinto ekufuneka uziqwalasele xa ukhetha izinto ze-granite ezifanelekileyo kwi-bridge CMM yakho.
1. Ubungakanani kunye nokuma
Ubungakanani kunye nemilo yezinto zegranite kufuneka zihambelane neempawu zebhulorho iCMM. Oku kuquka ubungakanani obupheleleyo, ubukhulu, ukuthamba, kunye nokuhambelana kweslab yegranite, kunye nokuma kunye nendawo yemingxunya okanye iindawo zokufaka. Igranite kufuneka ibe nobunzima obaneleyo kunye nokuqina ukuze kuncitshiswe ukungcangcazela kunye nokuguquguquka ngexesha lemisebenzi yokulinganisa, okunokuchaphazela ukuchaneka kunye nokuphindaphinda kweziphumo.
2. Umgangatho kunye neBanga
Umgangatho kunye nomgangatho wezinto zegranite nazo zinokuchaphazela ukusebenza kunye nobude bexesha lebhulorho yeCMM. Amanqanaba aphezulu egranite adla ngokuba noburhabaxa obuphantsi bomphezulu, iziphene ezimbalwa kunye nokufakwa, kunye nokuzinza okungcono kobushushu, konke oku kunokuphucula ukuchaneka kokulinganisa kunye nokuthembeka. Nangona kunjalo, iigranite ezikumgangatho ophezulu nazo zidla ngokuba zibiza kakhulu kwaye zisenokungabi yimfuneko kuzo zonke izicelo. Iigranite ezikumgangatho ophantsi zisenokufaneleka kwezinye izicelo zeCMM, ingakumbi ukuba ubungakanani kunye neemfuno zesimo azikho nzima kakhulu.
3. Iipropati zobushushu
Iimpawu zobushushu zezinto zegranite zinokuba nefuthe elikhulu ekuchanekeni kokulinganisa, ingakumbi kwiindawo ezinotshintsho olukhulu lobushushu. Igranite ine-coefficient ephantsi yokwandiswa kobushushu (CTE), nto leyo ethetha ukuba izinzile kuluhlu olubanzi lobushushu. Nangona kunjalo, iintlobo ezahlukeneyo zegranite zinokuba namaxabiso ahlukeneyo e-CTE, kwaye i-CTE inokwahluka ngokwendlela isakhiwo sekristale esihamba ngayo. Ke ngoko, kubalulekile ukukhetha izinto zegranite ezine-CTE ezihambelana noluhlu lobushushu olujikeleze indawo yokulinganisa, okanye ukusebenzisa iindlela zokuhlawula ubushushu ukuze kujongwe nayiphi na impazamo ebangelwe bubushushu.
4. Ixabiso kunye nokuFumaneka
Ixabiso kunye nokufumaneka kwezinto zegranite nako kuyinkxalabo esebenzayo kubasebenzisi abaninzi. Izinto zegranite ezisemgangathweni ophezulu zihlala zibiza kakhulu, ingakumbi ukuba zikhulu, zityebile, okanye zenziwe ngokwezifiso. Ezinye iintlobo zegranite nazo zisenokungafumaneki rhoqo okanye kube nzima ukuzifumana, ingakumbi ukuba zithengwa kwamanye amazwe. Ke ngoko, kubalulekile ukulinganisela iimfuno zokusebenza kwebhulorho yeCMM kunye nohlahlo-lwabiwo mali olukhoyo kunye nezixhobo, kunye nokubonisana nabathengisi okanye abavelisi abathembekileyo ukuze bafumane iingcebiso malunga neendlela ezifanelekileyo zokusebenzisa imali.
Ngamafutshane, ukukhetha izinto ezifanelekileyo zegranite ze-CMM yebhulorho kufuna ukuqwalaselwa ngononophelo ngobukhulu, imo, umgangatho, iimpawu zobushushu, ixabiso, kunye nokufumaneka kwezinto. Ngokugcina ezi zinto engqondweni nangokusebenzisana nababoneleli okanye abavelisi abanolwazi nabanamava, abasebenzisi banokuqinisekisa ukuba banenkqubo yokulinganisa ezinzileyo, ethembekileyo, nechanekileyo ehlangabezana neemfuno zabo ezithile kunye neemfuno.
