Kwiphulo elingapheliyo lokuchaneka kwesikali se-nanometer, amashishini okuvelisa kunye nee-semiconductor aye ajika kakhulu kwiibheringi zemveli zoomatshini aya kwisisombululo esintsonkothileyo ngakumbi: iindlela zokuthwala umoya we-granite echanekileyo. Njengoko oomatshini bekhawuleza kwaye iimfuno zokuchaneka ziba nzima ngakumbi, imida yeenkqubo zokuhamba ezisekelwe kuqhagamshelwano—ezifana nokukhuhlana, ukuguguleka, kunye nokuveliswa kobushushu—iye yaba yimiqobo ebalulekileyo. Iibheringi zomoya ze-granite ezenziwe ngokwezifiso zimele utshintsho oluqhelekileyo, oludibanisa uzinzo lwejoloji yelitye lendalo kunye nokusebenza okungenakukhuhlana kwetekhnoloji yefilimu yomoya ecinezelweyo ukuchaza kwakhona imida yokusebenza kolawulo lokuhamba.
Ukusebenzisana kwezinto zendalo kunye ne-Fluid Dynamics
Eyona nto iphambili kwezi nkqubo zisebenza kakuhle kukudibanisa i-granite emnyama kunye neebheringi ze-aerostatic. I-granite yeyona substrate ikhethwayo yeendlela ezichanekileyo ngenxa yeempawu zayo zomzimba ezingaqhelekanga. Ngokungafaniyo neentsimbi, i-granite ikhula ngokwemvelo kwiminyaka engaphezu kwezigidi, nto leyo ebangela ukuba izinto zingabi naxinzelelo lwangaphakathi. Ine-coefficient ephantsi yokwanda kobushushu kunye nokukwazi ukudambisa ukungcangcazela okuphezulu. Xa esi siseko sizinzileyo sidibene ukuya kuthi ga kwi-flatness egqithisileyo—edla ngokulinganiswa ngamaqhezu e-micrometer—iba yindlela efanelekileyo yokuqhuba i-air bearing.
Indlela yokuthwala umoya isebenza ngokuxhasa umthwalo kwifilimu encinci yomoya oxinzelelweyo, oqhele ukuba phakathi kwe-5 ukuya kwi-10 micrometers ubukhulu. Ngenxa yokuba akukho nxibelelwano phakathi kwenqwelo ehambayo kunye nomzila wegranite, i-friction coefficient iyasebenza njenge-zero ekuqaleni kwentshukumo. Oku kususa into "yokunamathela-ukutyibilika" eqhelekileyo kwiinkqubo zoomatshini, okuvumela utshintsho oluthambileyo, olukhawulezileyo kunye nokubekwa kwindawo entle kakhulu okungenakufikelelwa ziirola zoomatshini.
Ukwenza ngokwezifiso: Ukulungelelanisa iFiziksi ukuya kwiSicelo
Nangona kukho izinto ezingasetyenziswanga eshelufini, amandla okwenyani obu buchwephesha abonakaliswa ngobunjineli obuchanekileyo obukhethekileyo. Zonke izicelo eziphezulu, nokuba yinkqubo yokuhlola i-wafer okanye iziko lomatshini we-laser okhawulezayo, zineemfuno ezizodwa zomthamo womthwalo, ukuqina, kunye nobude bokuhamba. Ukwenza ngokwezifiso ijometri yeendlela zegranite kuvumela iinjineli ukuba zilungelelanise "umthwalo othwalayo" kubunzima obuthile bomthwalo.
Ukwenziwa ngokwezifiso kukwabandakanya ukuhlanganiswa kokufakwa kwe-vacuum-preloading. Kwiisetingi ezininzi ezichanekileyo, iibheringi zomoya ziyilwe ngee-vacuum ports zangaphakathi ezitsala inqwelo ukuya kumphezulu wegranite ngelixa uxinzelelo lomoya luyityhala kude. Le "mandla achaseneyo" idala ifilimu yomoya eqinileyo enokumelana namandla angaphandle kunye nokungcangcazela, iqinisekisa ukuba intshukumo ihlala imile kwaye izinzile naphantsi kwesantya esahlukileyo okanye utshintsho lwendlela. Ngokulungisa i-vacuum kunye nebhalansi yoxinzelelo, abavelisi banokulungisa ukuqina kwenkqubo ukuze ihambelane namaza ajikelezayo okusingqongileyo okuthile.
Ukoyisa Imingeni Yokungqubana Nobushushu
Kwiinkqubo zemveli zokuhamba, ukungqubana lutshaba lokungaguquguquki. Ukungqubana kuvelisa ubushushu, kwaye ubushushu bubangela ukuba izinto zoomatshini zande, nto leyo ekhokelela ekutshintsheni kwendlela ezisebenza ngayo. Kwiinkqubo zokuvelisa ezithatha umjikelo omde, nokunyuka okuncinci kobushushu kunokonakalisa iqela leenxalenye ezichanekileyo.
Iindlela zokubeka umoya wegranite ngendlela echanekileyo zisombulula oku ngokususa umthombo wobushushu. Ngaphandle kwezinto eziqengqelekayo okanye ukungqubana okutyibilikayo, akukho kwakheka kobushushu ngaphakathi kwebheringi ngokwayo. Ngaphezu koko, ukuhamba rhoqo komoya ocinezelweyo kwibheringi kusebenza njengenkqubo yokupholisa yendawo, nto leyo eqinisa ngakumbi imeko-bume. Oku kungathathi cala kobushushu yintsika yesizathu sokuba iibheringi zomoya zibe ngumgangatho weshishini kwiimashini zokulinganisa (ii-CMM) kunye nezigaba ze-optical lithography, apho ukwanda okuncinci kunokubangela iimpazamo ezinkulu zedatha.
Ukuqina kunye nokucoceka kwiindawo ezilawulwayo
Enye yezona ngxoxo zinamandla zokusebenzisa iindlela zokuthwala umoya wegranite bubomi bazo obungapheliyo. Kwinkqubo yokuthwala umoya yoomatshini, iindawo ekugqibeleni ziyadinwa, iirola ziyaguquguquka, kwaye ii-lubricants ziyawohloka okanye zingcoliseke. Oku kufuna ixesha lokungasebenzi ukuze kulungiswe kwaye kutshintshwe ekugqibeleni. Ngenxa yokuba ii-air bearing azinazo iindawo ezihambayo ezinxibelelanayo, akukho kugqwala nokukrazuka kumphezulu wegranite. Lo gama nje umoya uhlala ucocekile kwaye womile, inkqubo yokuthwala umoya wegranite inokugcina ukuchaneka kwayo kwefektri kangangamashumi eminyaka.
Oku kungagugi kwenza ezi nkqubo zilungele iindawo ezicocekileyo. Iibheringi zemveli zifuna igrisi okanye ioyile, ezinokukhupha igesi okanye zichithe amasuntswana, zingcolise izinto ezibuthathaka ze-elektroniki okanye ze-optical. Iibheringi zomoya “zicocekile” ngokwemvelo, zidinisa umoya ohluziweyo kuphela. Oku kuzenza zibe yimfuneko ekuvelisweni kwee-microchips, ii-flat-panels displays, kunye nezixhobo zonyango apho nokuba lisuntswana nje lothuli linokuba yintlekele.
Indima Yokuqhwaba Ngesandla Kwindlela Yanamhlanje Yokuchaneka
Nangona i-CNC grinding and polishing iphucukile, inqanaba lokugqibela lokuchaneka kwiindlela zegranite ezenziwe ngokwezifiso lihlala lifuna ukuchukunyiswa ngumntu. Iingcali zobugcisa zisebenzisa inkqubo ebizwa ngokuba yi-hand-lapping ukuze zifezekise ukuthamba kokugqibela kwe-sub-micron. Ngokusebenzisa ii-diamond abrasives kunye nezixhobo zokulinganisa ezikhethekileyo, zinokuchonga kwaye zisuse amabala aphezulu angabonakaliyo anokuphoswa ngoomatshini.
Olu mgangatho wobuchule luqinisekisa ukuba ifilimu yomoya ihlala ihambelana kulo lonke ixesha lohambo. Ukuba ireyile yegranite ayithe tyaba ngokupheleleyo, umsantsa womoya uya kwahluka, nto leyo ebangela utshintsho ekuqineni nasekubeni "kubekwe phantsi" kwebhereyitha. Umtshato wokugqitywa kwesandla sendabuko kunye ne-fluid dynamics yanamhlanje yiyo evumela iindlela zokuthwala umoya zegranite ezenziwe ngokwezifiso ukufezekisa ukunyamezelana okugqithisileyo kwejometri efunekayo kulawulo lokuhamba kwesizukulwana esilandelayo.
Ukudibanisa neTekhnoloji yeeMoto eziLinear
Ukuze zisebenzise ngokupheleleyo iingenelo zendlela yegranite engenasiphazamiso, ezi nkqubo zihlala zidibene neemoto ezizii-linear. Ngokungafaniyo nezikrufu zebhola, ezizisa ukungcangcazela koomatshini kunye nokubuyela umva, iimoto ezizii-linear zibonelela ngokuqhutywa okungadibaniyo. Xa imoto engadibaniyo idityaniswe nomoya ongadibaniyo kwisiseko segranite esizinzileyo, isiphumo siba yinkqubo yokuhamba engena-hysteresis yoomatshini.
Olu dibaniso luvumela ukukhawuleziswa okuphezulu kakhulu kunye namaxesha amafutshane okuzinza. Kwimizi-mveliso efana nokuhlanganiswa kwe-elektroniki, apho oomatshini kufuneka bashukume, bamise, kwaye baqalise isenzo amaxesha amaninzi ngeyure, ukukwazi ukuhlala kwindawo ekujoliswe kuyo ngaphakathi kwee-nanometers kwi-milliseconds ezimbalwa kutshintsha umdlalo we-throughput kunye ne-yield.
Isiphelo: Ukutyala imali kwikamva leNtshukumo
Utshintsho oluya kwiindlela zokuthwala umoya zegranite ezichanekileyo ngokwesiko asikokuqhelana nje kuphela; lutshintsho oluyimfuneko kumashishini asebenza kumda wemida ebonakalayo. Nangona utyalo-mali lokuqala kwigranite ekumgangatho ophezulu kunye neebheringi zomoya eziqhotyoshelweyo ziphezulu kunezo zereyile zentsimbi zemveli, iindleko zizonke zobunini—xa kujongwa ukungonakali, ukugcinwa okunciphileyo, kunye nesivuno esiphezulu—lwenza kube lolona khetho lungabizi kakhulu kubunjineli obuphezulu.
Njengoko singena nzulu kwixesha le-nanotechnology kunye nokuzisebenzela ngesantya esiphezulu, ukuzinza kwe-granite kunye nobuhle betekhnoloji ye-air-film kuya kuqhubeka nokuba sisiseko apho kwakhelwe khona oomatshini abachanekileyo kwihlabathi. Kwiinjineli kunye nabayili beenkqubo, ukuqonda ukusetyenziswa kwezi ndlela zesiqhelo sisitshixo sokuvula inqanaba elilandelayo lokusebenza kolawulo lokuhamba.
