Oomatshini bokulinganisa abadibeneyo, okanye ii-CMM, zizixhobo zokulinganisa ezichanekileyo ezisetyenziselwa ukulinganisa ubukhulu bento. I-CMM inee-axes ezintathu ezizimeleyo ezinokujikeleza kwaye zihambe kwiindlela ezahlukeneyo ukuze zithathe imilinganiselo yee-coordinates zento. Ukuchaneka kwe-CMM kubaluleke kakhulu, yiyo loo nto abavelisi bedla ngokuyakha ngezinto ezifana ne-granite, i-aluminium, okanye i-cast iron ukuqinisekisa uzinzo kunye nokuqina okufunekayo ukuze kulinganiswe ngokuchanekileyo.
Kwihlabathi leeCMM, igranite yenye yezona zinto zixhaphakileyo ezisetyenziselwa isiseko somatshini. Oku kungenxa yokuba igranite izinzile kwaye iqinile, nto leyo ebalulekileyo ekulinganisweni ngokuchanekileyo. Ukusetyenziswa kwegranite ekwakhiweni kweeCMM kunokulandelwa emva phakathi kwinkulungwane yama-20 xa ubuchwepheshe baqala ukuvela.
Nangona kunjalo, ayizizo zonke iiCMM ezisebenzisa igranite njengesiseko sazo. Iimodeli ezithile kunye neebrendi zinokusebenzisa ezinye izinto ezifana nesinyithi esityhidiweyo, i-aluminium, okanye izinto ezidityanisiweyo. Nangona kunjalo, igranite iselukhetho oludumileyo phakathi kwabavelisi ngenxa yeempawu zayo eziphezulu. Enyanisweni, ixhaphake kakhulu kangangokuba uninzi lucinga ngokusetyenziswa kwegranite njengomgangatho weshishini ekuvelisweni kweeCMM.
Enye yezinto ezibalulekileyo ezenza i-granite ibe yinto efanelekileyo yokwakha isiseko se-CMM kukungachaphazeleki kwayo kutshintsho lobushushu. I-granite, ngokungafaniyo nezinye izinto, inamazinga okwanda kobushushu aphantsi kakhulu, okwenza ukuba imelane notshintsho lobushushu. Le mpawu ibalulekile kwi-CMM kuba naluphi na utshintsho kubushushu lunokuchaphazela ukuchaneka komatshini. Olu buchule lubaluleke kakhulu xa usebenza ngokulinganisa ngokuchanekileyo izinto ezincinci ezifana nezo zisetyenziswa kwimizi-mveliso yeenqwelo-moya, iimoto, kunye nezonyango.
Enye into eyenza igranite ibe yeyona ifanelekileyo ukusetyenziswa kwi-CMMs bubunzima bayo. Igranite lilitye elixineneyo elinika uzinzo oluhle kakhulu ngaphandle kokufuna inkxaso eyongezelelweyo okanye ukuxhaswa. Ngenxa yoko, i-CMM eyenziwe ngegranite inokumelana nokungcangcazela ngexesha lenkqubo yokulinganisa ngaphandle kokuchaphazela ukuchaneka kokulinganisa. Oku kubaluleke kakhulu xa kulinganiswa iindawo ezinokunyamezelana okuqinileyo.
Ngaphezu koko, i-granite ayichaphazeleki ziikhemikhali ezininzi, iioyile, kunye nezinye izinto zoshishino. Le nto ayidli mhlwa, ayidli mhlwa okanye itshintshe umbala, nto leyo eyenza kube lula ukuyigcina icocekile. Oku kubalulekile kwiindawo zoshishino ezifuna ukucocwa rhoqo okanye ukususwa kongcoliseko ngenxa yezizathu zococeko.
Ukuqukumbela, ukusetyenziswa kwegranite njengezinto ezisisiseko kwi-CMMs yinto eqhelekileyo nethandwayo kushishino. Igranite inika indibaniselwano entle yozinzo, ukuqina, kunye nokungathinteli utshintsho lobushushu olubalulekileyo ekulinganisweni ngokuchanekileyo kwezinto zoshishino. Nangona ezinye izinto ezifana nesinyithi esityhidiweyo okanye i-aluminium zinokusebenza njengesiseko se-CMM, iimpawu zegranite ezisisiseko zenza ukuba ibe lolona khetho lukhethwayo. Njengoko ubuchwepheshe buqhubeka, ukusetyenziswa kwegranite kwi-CMMs kulindeleke ukuba kuhlale kuyinto ebalaseleyo ngenxa yeempawu zayo eziphezulu.
