Xa kufikwa ekulinganisweni ngokuchanekileyo, iipleyiti zomphezulu wegranite zithathwa njengomgangatho wegolide. Uzinzo lwazo lwendalo, ukuthamba okugqwesileyo, kunye nokumelana nokuguguleka kuzenza zibe yeyona nto ibalulekileyo kwiilebhu zemetrology, amagumbi okuhlola umgangatho, kunye neendawo zokwenza izinto eziphezulu. Nangona kunjalo, ngelixa uninzi lwabasebenzisi lugxila ekuchanekeni komphezulu kunye nokunyamezelana, kukho enye into ebalulekileyo echaphazela ngokuthe ngqo ukusebenza kunye nobude bepleyiti yegranite - ubukhulu bayo. Ukuqonda indlela ubukhulu obumiselwa ngayo kunye nendlela obuhambelana ngayo nomthamo womthwalo kunye nozinzo kubalulekile ekukhetheni iqonga elifanelekileyo lezixhobo zakho kunye nokuqinisekisa ukuchaneka kokulinganisa ixesha elide.
Ubukhulu bepleyiti yomphezulu wegranite bungaphezulu kakhulu kunendlela yokulinganisa ubukhulu. Yisiseko sobume bepleyiti. Okukhona igranite ityebile, kokukhona inamandla okuxhasa izixhobo ezinzima ngaphandle kokugoba okanye ukujika. Oku kuchaphazela ngokuthe ngqo ukuthembeka komlinganiselo kuba nokuba ukujika okuncinci - ngamanye amaxesha kulinganiswa ngee-microns - kunokukhokelela ekungachaneki ekuhlolweni okanye ekulinganisweni. Kwelinye icala, ipleyiti etyebile kakhulu inokuba nzima ngokungeyomfuneko, ibiza kakhulu, kwaye kunzima ukuyifaka. Isisombululo esifanelekileyo sikukulinganisela ubukhulu neemfuno zesicelo.
Enye yezinto eziphambili ekufuneka ziqwalaselwe xa kumiselwa ubukhulu bubunzima bezixhobo eziza kubekwa kwipleyiti. Kwizicelo ezilula — ezinje ngeemakroskopu, iigeyiji, okanye izixhobo ezincinci zokulinganisa — ipleyiti encinci inokwanela, njengoko umthwalo osetyenziswayo uncinci. Kodwa njengoko ubunzima busanda, nobukhulu bufanele bube njalo. Oomatshini abanjengoomatshini bokulinganisa abadibeneyo (ii-CMM), iinkqubo zokulinganisa ezibonakalayo, okanye izixhobo zokuhlanganisa ezinzima banamandla amakhulu kumphezulu, kwaye ipleyiti enobukhulu obunganelanga inokonakala kancinci kancinci phantsi komthwalo. Ekuhambeni kwexesha, olu tshintsho lukhokelela ekulahlekelweni kokuthe tyaba, okuphazamisa injongo yokusebenzisa ipleyiti yomphezulu ochanekileyo.
Ubukhulu bukwadlala indima ebalulekileyo ekukwazini kwepleyiti ukumelana neempembelelo zokusingqongileyo. I-granite ngokwemvelo iyakhula kwaye inciphe kancinci kakhulu xa kutshintshwe ubushushu, kodwa iipleyiti ezityebileyo ziyakwazi ukumelana nokuguquguquka kobushushu. Zinobunzima obukhulu bobushushu, oko kuthetha ukuba zisabela kancinci xa kutshintshwe ubushushu, nto leyo enceda ekugcineni uzinzo lobukhulu nokuba imeko-bume engqongileyo ayilunganga. Olu phawu lubaluleke kakhulu kwiindawo zokusebenzela okanye kwiindawo zokwenza izinto apho ulawulo lobushushu lunzima khona.
Enye into ephenjelelwa bubukhulu bubomi benkonzo yexesha elide bepleyiti yegranite. Ipleyiti enobukhulu obufanelekileyo bokusetyenziswa kwayo inokuhlala izinzile kwaye ichanekile amashumi eminyaka. Ngokwahlukileyo koko, leyo incinci kakhulu kumthwalo ewuxhasayo ekuqaleni isenokuhlangabezana neemfuno zokuba tyaba kodwa kancinci kancinci ilahlekelwe bubuchane bayo njengoko iminyaka ihamba. Olu hlobo lokuguquguquka okucothayo ludla ngokungabi nakuguqulwa kwaye lunokufuna ukulungiswa kwakhona okubiza kakhulu okanye ukutshintshwa ngokupheleleyo.
Imigangatho yoshishino efana ne-DIN, i-JIS, kunye ne-ASME inika ubungqingqwa obucetyiswayo bobukhulu beepleyiti ezahlukeneyo kunye namanqanaba okuchaneka, kodwa oku kufuneka kuthathwe njengezikhokelo kunokuba kube yimithetho engqongqo. Yonke into esetyenziswayo yahlukile, kwaye izinto ezifana nomthwalo uwonke, indlela umthwalo osasazwa ngayo, ubukho bamandla aguqukayo, kunye nohlobo lwesakhiwo senkxaso esisetyenziswa phantsi kwepleyiti zonke zinokuchaphazela ubukhulu obufanelekileyo. Kusoloko kucetyiswa ukuba udibane nomenzi xa uchaza ipleyiti yegranite, ngakumbi kwizicelo ezingezizo ezisemgangathweni okanye ezinzima.
Ngokwendlela yokusebenza, ubudlelwane phakathi kobukhulu, ubukhulu, kunye nokusebenza bulula. Iipleyiti ezinkulu zifuna ubukhulu obukhulu ukuze zigcine ukuqina phezu kwendawo yazo, kwaye amanqanaba aphezulu okuchaneka adla ngokufuna iipleyiti ezityebileyo ukuze kuncitshiswe ukuphambuka. Umzekelo, ipleyiti yomphezulu eyi-1000 mm esetyenziselwa uhlolo ngokubanzi inokuba nobukhulu obuyi-150 mm, ngelixa ipleyiti eyi-2000 mm exhasa umatshini wokulinganisa onzima ingadinga i-300 mm nangaphezulu. Abavelisi abanjengoZHHIMG banikezela ngeenkcukacha ezineenkcukacha kunye neetshathi zomthamo womthwalo ukukhokela abathengi kuyilo olufanelekileyo kwiimfuno zabo.
Ukugcinwa kwakhona kudlala indima ekugcineni ukusebenza kwepleyiti yomphezulu wegranite, nokuba ingakanani na ubukhulu bayo. Ukugcina umphezulu ucocekile kwaye ungenaluthuli, ukuphepha ukungqubana ngequbuliso, kunye nokuqinisekisa ukuba ipleyiti ayixinene kakhulu zizinto ezibalulekileyo. Ukuhlolwa rhoqo kokulinganisa kuyacetyiswa ukuqinisekisa ukuba ukuthamba kuhlala ngaphakathi kwemida eyamkelekileyo. Ngononophelo olufanelekileyo, ipleyiti yegranite ekhethwe kakuhle inokubonelela ngemilinganiselo ezinzileyo nethembekileyo kangangeminyaka emininzi.
Ekugqibeleni, ubukhulu abuyonto nje yokulinganisa ngokwasemzimbeni — yiparameter ebalulekileyo yobunjineli exhasa ukusebenza, ukuqina, kunye nokuchaneka kwepleyiti yomphezulu wegranite. Ngokuqwalasela ngononophelo ubunzima bezixhobo zakho, indawo eza kusetyenziswa kuyo ipleyiti, kunye nobomi benkonzo obulindelekileyo, ungakhetha iqonga eliza kuxhasa umsebenzi wakho wokuchaneka iminyaka emininzi. Njengoko ukunyamezelana kokuvelisa kuya kusiba nzima ngakumbi kwaye ukuchaneka kokulinganisa kubaluleke ngakumbi kunangaphambili, ukunikel’ ingqalelo kwiinkcukacha ezifana nobukhulu bepleyiti akuyomfuneko yobugcisa nje kuphela — yinzuzo yokukhuphisana.
