Xa kuziwa kumlinganiselo ochanekileyo, iipleyiti zomphezulu wegranite zithathwa njengomgangatho wegolide. Uzinzo lwabo lwendalo, ukuthamba okukhethekileyo, kunye nokuxhathisa ukunxiba kubenza babaluleke kakhulu kwiilebhu ze-metrology, amagumbi okuhlola umgangatho, kunye neendawo zokwenziwa eziphezulu. Nangona kunjalo, ngelixa uninzi lwabasebenzisi lujolise ekuchanekeni komphezulu kunye nokunyamezelana, kukho enye into ebalulekileyo echaphazela ngokuthe ngqo ukusebenza kunye nobomi obude bepleyiti yegranite - ubukhulu bayo. Ukuqonda ukuba ubukhulu bunqunywe njani kwaye buhambelana njani nomthamo wokulayisha kunye nokuzinza kubalulekile ekukhetheni iqonga elifanelekileyo lezixhobo zakho kunye nokuqinisekisa ukuchaneka komlinganiselo wexesha elide.
Ubukhulu bepleyiti yomphezulu wegranite ingaphezulu lee kunomlinganiselo nje wokuchazwa komda. Sisiseko semfezeko yolwakhiwo lwepleyiti. Okukhona ijiyile igranite, kokukhona amandla ayo okuxhasa izixhobo ezinzima ngaphandle kokugoba okanye ukuphambuka. Oku kuchaphazela ngokuthe ngqo ukuthembeka komlinganiselo ngenxa yokuba nokuphambuka okuncinci - ngamanye amaxesha kulinganiswe kwi-microns - kunokukhokelela ekungalungini kokuhlolwa okanye ukulinganisa. Kwelinye icala, ipleyiti engqindilili ngokugqithisileyo inokuba nzima ngokungeyomfuneko, ibize kakhulu, kwaye kube nzima ukuyifaka. Isisombululo esisiso silele ekulinganiseni ubukhulu kunye neemfuno zesicelo.
Enye yeengqwalasela eziphambili xa kumiselwa ubukhulu bubunzima bezixhobo eziza kufakwa kwi-plate. Ukusetyenziswa kokukhanya okukhanyayo - okufana ne-microscopes, i-gauges, okanye izixhobo ezincinci zokulinganisa - ipleyiti encinci inokwanela, njengoko umthwalo osetyenzisiweyo uncinci. Kodwa njengoko ubunzima bukhula, kufuneka ngokunjalo ubukhulu. Oomatshini abafana noomatshini bokulinganisa abalungelelanisiweyo (ii-CMMs), iisistim zokulinganisa okubonakalayo, okanye izixhobo ezidityanisiweyo ezinzima zisebenzisa amandla abalulekileyo kumphezulu, kwaye ipleyiti enobungqingqwa obungonelanga inokonakala kancinci kancinci phantsi komthwalo. Ngokuhamba kwexesha, olu tshintsho lukhokelela ekulahlekeni kokutyalwa, okonakalisa eyona njongo yokusebenzisa ipleyiti yomphezulu echanekileyo.
Ukutyeba kukwadlala indima ebalulekileyo ekukwazini kwepleyiti ukuxhathisa iimpembelelo zendalo. Igranite ngokwendalo iyanda kwaye yenza izivumelwano ezincinci kakhulu ngotshintsho lobushushu, kodwa iipleyiti ezityebileyo ziyakwazi ukumelana nokuguquguquka kobushushu. Banobunzima obukhulu be-thermal, okuthetha ukuba basabela ngokucothayo kutshintsho lweqondo lobushushu, olunceda ukugcina uzinzo lwe-dimensional naxa imo engqongileyo ingaphantsi kunokulunga. Olu phawu lubaluleke kakhulu kwiindibano zocweyo okanye kwiindawo zokuvelisa apho kunzima ukulawula ubushushu.
Enye inkalo echatshazelwa bubunzima bubomi benkonzo yexesha elide yepleyiti yegranite. Ipleyiti enobunzima obuchanekileyo bokusetyenziswa kwayo inokuhlala izinzile kwaye ichanekile amashumi eminyaka. Ngokwahlukileyo koko, leyo ibhitye kakhulu kumthwalo ewuxhasayo inokuqala ukuhlangabezana neemfuno zokucaba kodwa ngokuthe ngcembe iphulukane nokuchaneka kwayo njengoko iminyaka ihamba. Olu hlobo lotshintsho olucothayo luhlala lungenakurhoxiswa kwaye lunokufuna ukufakwa kwakhona komphezulu okuneendleko eziphezulu okanye ukutshintshwa okupheleleyo.
Imigangatho yeshishini efana ne-DIN, i-JIS, kunye ne-ASME ibonelela ngobunzima obucetyiswayo bobungakanani beepleyiti ezahlukeneyo kunye namabakala achanekileyo, kodwa ezi kufuneka ziqwalaselwe izikhokelo kunemithetho engqongqo. Isicelo ngasinye siyingqayizivele, kwaye izinto ezinjengomthwalo opheleleyo, indlela umthwalo osasazwa ngayo, ubukho bemikhosi eguquguqukayo, kunye nohlobo lwesakhiwo senkxaso esisetyenzisiweyo phantsi kwepleyiti sinokuphembelela ubukhulu obufanelekileyo. Kuhlala kucetyiswa ukuba udibane nomvelisi xa uchaza ipleyiti yegranite, ngakumbi kwizicelo ezingekho mgangathweni okanye ezinzima.
Ngokwezinto eziphathekayo, ubudlelwane phakathi kobukhulu, ubukhulu, kunye nokusebenza ngokuthe ngqo. Iipleyiti ezinkulu zifuna ubukhulu obukhulu ukugcina ukuqina kwindawo yazo, kwaye amanqanaba aphezulu achanekileyo afuna iipleyiti ezityebileyo ukunciphisa ukuphambuka. Umzekelo, ipleyiti yomphezulu eyi-1000 mm esetyenziselwa ukuhlolwa ngokubanzi inokuba yi-150 mm ubukhulu, ngelixa ipleyiti eyi-2000 mm exhasa umatshini wokulinganisa onzima inokufuna i-300 mm okanye ngaphezulu. Abavelisi abanje nge-ZHHIMG babonelela ngeenkcukacha ezithe kratya kunye nomthamo weetshathi ukukhokela abathengi kolona yilo lufanelekileyo kwiimfuno zabo.
Ukugcinwa kwakhona kudlala indima ekugcineni ukusebenza kwe-granite surface plate, kungakhathaliseki ukuba ubukhulu bayo. Ukugcina umphezulu ucocekile kwaye ungenathuli, ukuphepha iimpembelelo zequbuliso, kunye nokuqinisekisa ukuba ipleyiti ayigcwalanga zizenzo ezibalulekileyo. Kukwacetyiswa ukuba kujongwe uhlengahlengiso oluthe gqolo ukuze kuqinisekiswe ukuba intuba ihlala ngaphakathi kwemida eyamkelekileyo. Ngononophelo olufanelekileyo, ipleyiti yegranite ekhethiweyo kakuhle inokuhambisa imilinganiselo ezinzileyo kunye nethembekileyo amashumi eminyaka.
Ekugqibeleni, ubukhulu bungaphezulu nje komlinganiselo womzimba - yiparameter yobunjineli ebalulekileyo exhasa ukusebenza, ukuqina, kunye nokuchaneka kwepleyiti yomphezulu wegranite. Ngokuqwalasela ngokucophelela ubunzima bezixhobo zakho, indawo apho ipleyiti iya kusetyenziswa khona, kunye nobomi obulindelekileyo benkonzo, unokukhetha iqonga eliza kuxhasa umsebenzi wakho ochanekileyo iminyaka emininzi. Njengoko unyamezelo lwemveliso lusiya luqina ngakumbi kwaye ukuchaneka komlinganiselo kubaluleke ngakumbi kunangaphambili, ukunikela ingqalelo kwiinkcukacha ezinje ngobungqingqwa bepleyiti ayisiyomfuneko yobugcisa kuphela - lulutho olukhuphisanayo.
