Kwimeko enzima yokwenziwa ngokuchanekileyo kunye nolawulo lomgangatho, ukukhetha ipleyiti yomphezulu sisigqibo esisisiseko esichaphazela kakhulu ukuchaneka, ukuthembeka, kunye nokusebenza kakuhle kwemisebenzi ye-metrology. Ezi ndawo zithe tyaba ngononophelo zisebenza njengedatha ephambili yokuhlolwa, uyilo, kunye nemisebenzi yokulinganisa, okwenza ukwakheka kwezinto zazo kube yinto ebalulekileyo. Kangangamashumi eminyaka, ingxoxo phakathi kwegranite kunye neepleyiti zomphezulu wesinyithi esityhidiweyo ibisoloko iphambili kwiingcali ze-metrology, nganye inika iingenelo kunye neengqwalasela ezahlukeneyo. Ukuqonda iimpawu ezicacileyo zazo zombini kubalulekile ekukhetheni iqonga elifanelekileyo elihambelana neemfuno ezithile zokusebenza kunye nembuyekezo yexesha elide kutyalo-mali.
Ilifa Elihlala Lihleli LeePlati Zomphezulu Wesinyithi Esixonxiweyo
Iipleyiti zomphezulu wesinyithi ezibunjiweyo zinembali ende neyahlukileyo kwi-metrology, zikho ngaphambi kokuba i-granite isetyenziswe ngokubanzi. Ukuqina kwazo kunye neempawu zazo ezizodwa zenze ukuba zibe yinto eqhelekileyo kwiindawo ezininzi zoshishino, ingakumbi apho ukusetyenziswa okunzima kunye nokulungiswa kubaluleke kakhulu.
Amandla oomatshini kunye nokumelana nempembelelo
Enye yezona zinto ziphambili ezisebenza ngentsimbi ephosiweyo ikukuba inamandla aphezulu oomatshini kunye nokumelana nempembelelo. Ngokungafaniyo negranite, enokuqhekeka okanye iqhekeke xa itshatyalaliswe kakhulu, intsimbi ephosiweyo ihlala ixesha elide kwaye inokumelana noxinzelelo olukhulu loomatshini. Oku kwenza iipleyiti zentsimbi ephosiweyo zilungele kakhulu iindawo apho izinto ezinzima zihlala ziphathwa khona, okanye apho kukho umngcipheko ophezulu wokuwa okanye ukungqubana ngengozi. Ukuqina kwayo okuqhelekileyo kuqinisekisa ukuba ipleyiti inokunyamezela ubunzima bomgangatho wemveliso oguqukayo ngaphandle kokubeka emngciphekweni ulwakhiwo lwayo.
Ubuchule bokusebenza kunye nokuguquguquka
Isinyithi esitshisiweyo kulula kakhulu ukusisebenzisa kunegranite, nto leyo evumela ukuhlanganiswa okulula kweempawu ezahlukeneyo ngqo kwipleyiti. Oku kuquka ii-T-slots, imingxunya enemisonto, kunye neendlela zokubambelela, ezibalulekileyo ekuqiniseni izinto zokusebenza kunye nezixhobo ngexesha lokuhlolwa okanye ukuhlanganiswa. Oku kuguquguquka kwenza iipleyiti zomphezulu wesinyithi esitshisiweyo zibe luncedo kakhulu kwizicelo ezifuna ukulungiswa rhoqo okanye ukusetyenziswa kwezixhobo ezikhethekileyo. Ngaphezu koko, ukukwazi ukusifaka ngomatshini isinyithi kuvumela ukwenziwa ngokwezifiso ngokuchanekileyo ukuhlangabezana neemfuno zokusebenza ezizodwa, okubonelela ngenqanaba lokuguquguquka elingenakukwazi ukulilingana ngokulula negranite.
Ukulungiswa kunye nobude bexesha elide
Inzuzo ecacileyo yeepleyiti zomphezulu wesinyithi esityhidiweyo kukulungiswa kwazo. Ekuhambeni kwexesha, kwanezona ndawo ziqinileyo zinokuguguleka okanye zonakale. Xa ipleyiti yesinyithi esityhidiweyo iguguleka okanye ukuba buthathaka kwayo konakala, idla ngokukhuhla okanye iphindwe idityaniswe ziingcali ukuze kubuyiselwe ukuchaneka kwayo kwasekuqaleni. Olu buchule bokuhlaziywa bukwandisa ubomi bepleyiti yesinyithi esityhidiweyo, nto leyo eyenza ukuba ibe lukhetho oluzinzileyo nolungabizi kakhulu ekuhambeni kwexesha, ngakumbi kwiiyunithi ezinkulu nezibiza kakhulu. Olu lungiso luyahluka kwigranite, ethi, xa yonakele kakhulu okanye iguguleke ngaphaya kwendawo ethile, idla ngokufuna ukutshintshwa.
Ukuqhuba kweThermal
Isinyithi esitshisiweyo sinomoya ophezulu wokuqhuba ubushushu xa kuthelekiswa negranite. Nangona oku kunokuba yingxaki ngokubhekiselele kuzinzo lobushushu (njengoko kuxoxwe ngako kamva), kunokuba luncedo nakwiimeko ezithile apho kufuneka ukulingana kobushushu ngokukhawuleza kwipleyiti, okanye apho ipleyiti kufuneka ikhuphe ubushushu obuveliswa yi-workpiece okanye indawo engqongileyo ngokukhawuleza.
Ulawulo Lwanamhlanje lweePlati zeGranite Surface
Iipleyiti zomphezulu wegranite zafumana udumo ngexesha leMfazwe Yehlabathi yesiBini, ekuqaleni zathatha indawo yesinyithi, kodwa zakhawuleza zabonisa ukuba zikumgangatho ophezulu. Namhlanje, zingumgangatho weshishini wokusetyenziswa ngokuchanekileyo, zithandwa ngenxa yeempawu zazo zangaphakathi ezinciphisa ukungaqiniseki komlinganiselo.
Uzinzo oluKhethekileyo noLwandiso oluphantsi lobushushu
Eyona nto idumileyo ngegranite kwi-metrology kukuzinza kwayo okubalaseleyo, ngokuyintloko ngenxa ye-coefficient yayo ephantsi kakhulu yokwandiswa kobushushu (CTE). I-CTE yeGranite imalunga nesinye kwisithathu kuneyentsimbi ephosiweyo (umz., 4.6 x 10⁻⁶/°C kwigranite xa kuthelekiswa ne-11 x 10⁻⁶/°C kwintsimbi ephosiweyo). Oku kuthetha ukuba iipleyiti zegranite azichaphazeleki kakhulu kukwanda kobushushu kunye nokuncitshiswa okubangelwa kukutshintshatshintsha kobushushu. Kwiilebhu ze-metrology ezilawulwa bubushushu, olu phawu luqinisekisa ukuba umphezulu wesalathiso uhlala uthe tyaba kwaye uchanekile rhoqo, kunciphisa iimpazamo zobushushu ezinokuchaphazela kakhulu ukuchaneka kokulinganisa. Olu zinzo lobushushu oluyimvelaphi lusisiseko se-metrology echanekileyo kakhulu, ebonelela ngedatha ethembekileyo nangona kukho utshintsho oluncinci lokusingqongileyo.
Iimpawu zokudambisa ukungcangcazela eziphezulu
Ukulinganisa ngokuchanekileyo kusengozini enkulu yokungcangcazela, okunokungenisa ingxolo kunye nokungazinzi kwinkqubo yokulinganisa. I-Granite ineempawu ezintle kakhulu zokungcangcazela kwendalo ngenxa yesakhiwo sayo esixineneyo nesikristale. Ifunxa kwaye ichithe ngempumelelo ukungcangcazela koomatshini, idala
indawo ezolileyo yezixhobo ezibuthathaka. Ngokwahlukileyo koko, isinyithi esityhidiweyo sidla 'ngokurhangqa' okanye ngokungcangcazela ngakumbi, sidla ngokufuna ezinye izixhobo zokudambisa ezikhethekileyo kwizicelo zemetrology eziphezulu. Olu buchule bokudambisa obuphezulu begranite bubalulekile ekufezekiseni imilinganiselo ephindaphindwayo nechanekileyo, ingakumbi xa kusetyenzwa ngezixhobo ezibuthathaka okanye ukwenza imilinganiselo kumanqanaba angaphantsi kwe-micron.
Ukuqina Kwemvelo, Ukumelana Nokuguguleka, kunye Nokungalungeki Kweekhemikhali
I-granite inzima kakhulu kune-cast iron, idla ngokuba nobunzima obuyi-Mohs obuyi-6 ukuya kwi-7. Obu bunzima bubalaseleyo buguqulela ekubeni bube nokumelana nokuguguleka okungaqhelekanga, okwenza iipleyiti ze-granite zimelane kakhulu nokukrweleka nokukrala kwiindawo ezityibilikayo kumphezulu wazo. Ngononophelo olufanelekileyo, ipleyiti yomphezulu we-granite inokugcina ukuchaneka kwayo amashumi eminyaka, inika ubomi obude kakhulu. Ngaphezu koko, i-granite ayinazimbobo, ayinamagnethi, kwaye ayinayo ikhemikhali. Oku kuthetha ukuba ayichaphazeleki ngokupheleleyo kukugqwala nokugqwala okuvela kwiioyile, izinto ezipholileyo, okanye ukufuma, okususa isidingo sokugcinwa rhoqo njengokugalela ioyile okufunekayo kwi-cast iron. Ipropati yayo engeyiyo imagnethi ikwaluncedo ekuhloleni izinto kwicandelo le-elektroniki okanye leenqwelo moya, apho ukuphazamiseka kwemagnethi kunokuba yingxaki.
Ukulungiswa okulula
Iimfuneko zokugcinwa kweepleyiti zomphezulu wegranite ziphantsi kakhulu. Ukusula nje ngesicoci esikhethekileyo kudla ngokuba yinto efunekayo ukugcina umphezulu ucocekile. Ukungabikho komhlwa kunye nokuzinza kwezinto kuthetha ukuba iipleyiti zegranite azigobeki ngokuhamba kwexesha ngenxa yokukhululeka koxinzelelo lwangaphakathi, ngokungafaniyo nentsimbi ephosiweyo enokufuna ukukrwelwa kwakhona okanye ukuphindaphindwa rhoqo ukulungisa ukugqwetheka. Olu phawu luphantsi lokugcinwa lunegalelo elikhulu ekusebenzeni kakuhle kweendleko zepleyiti zegranite ixesha elide.
