Ekufuneni okungapheli kokunemba kwesikali se-nanometer, izimboni zokukhiqiza kanye neze-semiconductor ziye zaphenduka kakhulu kuma-bearings endabuko asebenzisa imishini zaya esixazululweni esiyinkimbinkimbi kakhulu: izindlela zokuthwala umoya we-granite ngokunemba. Njengoba imishini iba ngokushesha futhi izidingo zokunemba ziba nzima kakhulu, ukulinganiselwa kwezinhlelo zokunyakaza ezisekelwe ekuthinteni—njengokungqubuzana, ukuguguleka, kanye nokukhiqizwa kokushisa—kuye kwaba yizithiyo ezibalulekile. Ama-bearings omoya we-granite aklanywe ngokwezifiso amelela ushintsho olufana nolwemvelo, oluhlanganisa ukuzinza kwe-geological kwetshe lemvelo kanye nokusebenza kahle okungenazingxabano kobuchwepheshe befilimu yomoya ecindezelwe ukuze kuchazwe kabusha imingcele yokusebenza kokulawula ukunyakaza.
Ukusebenzisana Kwezinto Zemvelo kanye Nezimo Zoketshezi
Enhliziyweni yalezi zinhlelo zokusebenza okuphezulu kukhona ukuhlanganiswa kwe-granite emnyama nama-bearings aerostatic. I-granite iyindawo ekhethwayo yezindlela zokunemba ngenxa yezakhiwo zayo ezingavamile zomzimba. Ngokungafani nezinsimbi, i-granite iguga ngokwemvelo eminyakeni eyizigidi, okuholela ezintweni ezingenazo izingcindezi zangaphakathi. Ine-coefficient ephansi yokwanda kokushisa kanye namakhono aphezulu okunciphisa ukudlidliza. Uma lesi sisekelo esizinzile sixhunyaniswe sibe yi-flatness enkulu—ngokuvamile silinganiswa ngama-micrometer—siba yindawo efanele yokugijima ye-air bearing.
Indlela yokuthwala umoya isebenza ngokusekela umthwalo efilimini elincane lomoya ocindezelwe, ngokuvamile kusuka kuma-micrometer angu-5 kuya kwangu-10 ubukhulu. Ngenxa yokuthi akukho ukuthintana ngokomzimba phakathi kwenqola ehambayo kanye nesitimela se-granite, i-coefficient yokungqubuzana i-zero ekuqaleni kokunyakaza. Lokhu kuqeda isenzakalo "sokunamathela" esivame kakhulu ezinhlelweni zemishini, okuvumela ukuguquka okubushelelezi, okusheshayo kanye nokubekwa okuhle kakhulu okungenakufezwa ama-roller emishini.
Ukwenza Ngokwezifiso: Ukulungisa iFiziksi kuya Ekusetshenzisweni
Nakuba kunezingxenye ezitholakala eshalofini, amandla angempela alobu buchwepheshe abonakala ngobunjiniyela bokucacisa ngokwezifiso. Zonke izinhlelo zokusebenza eziphezulu, kungakhathaliseki ukuthi uhlelo lokuhlola i-wafer noma isikhungo somshini we-laser esisheshayo, zinezidingo ezihlukile zomthamo womthwalo, ukuqina, kanye nobude bokuhamba. Ukwenza ngokwezifiso i-geometry yezindlela ze-granite kuvumela onjiniyela ukuthi bathuthukise "unyawo lokuthwala" kusisindo esithile somthwalo okhokhelwayo.
Ukwenza ngokwezifiso kuhilela nokuhlanganiswa kokulayisha kuqala kwe-vacuum. Ezinhlelweni eziningi ezinembe kakhulu, ama-air bearings aklanywa ngama-vacuum port angaphakathi adonsela inqola endaweni ye-granite ngenkathi ingcindezi yomoya iyisunduza. Leli "mandla aphikisanayo" lidala ifilimu yomoya eqinile kakhulu engamelana namandla angaphandle nokudlidliza, okuqinisekisa ukuthi ukunyakaza kuhlala kuqondile futhi kuzinzile ngisho nangaphansi kwesivinini esishintshashintshayo noma izinguquko eziqondisayo. Ngokulungisa ibhalansi ye-vacuum kanye nengcindezi, abakhiqizi bangalungisa ukuqina kwesistimu ukuze kufane namaza okuzwakalayo endawo ethile.
Ukunqoba Izinselele Zokungqubuzana Nokushisa
Ezinhlelweni zokunyakaza zendabuko, ukungqubuzana kuyisitha sokungaguquguquki. Ukungqubuzana kudala ukushisa, futhi ukushisa kubangela ukuthi izingxenye zemishini zande, okuholela ekushintsheni kokubeka izinto endaweni yazo. Ezinqubweni zokukhiqiza zomjikelezo omude, ngisho nokwenyuka okuncane kwezinga lokushisa kungonakalisa iqoqo lezingxenye ezinembe kakhulu.
Izindlela zokuthwala umoya ze-granite eziqondile zixazulula lokhu ngokususa umthombo wokushisa. Ngaphandle kwezinto ezigoqekayo noma ukungqubuzana okushelelayo, akukho ukwakheka kokushisa ngaphakathi kwe-bearing uqobo. Ngaphezu kwalokho, ukugeleza okuqhubekayo komoya ocindezelwe nge-bearing kusebenza njengohlelo lokupholisa olusendaweni, okuqinisa imvelo. Lokhu kungathathi hlangothi kokushisa kuyitshe lesisekelo sokuthi kungani ama-air bearing eyindinganiso yemboni yemishini yokulinganisa edidiyelwe (ama-CMM) kanye nezigaba ze-optical lithography, lapho ukwanda okuncane kungabangela amaphutha amakhulu edatha.
Ukuqina Nokuhlanzeka Ezindaweni Ezilawulwayo
Esinye sezimpikiswano ezibaluleke kakhulu zokusebenzisa izindlela zokuthwala umoya we-granite impilo yazo yokusebenza engapheli. Ohlelweni lokuthwala umoya olusebenzisa imishini, izingxenye ekugcineni ziyakhathala, ama-roller ayawohloka, futhi amafutha okugcoba ayawohloka noma angcole. Lokhu kudinga isikhathi sokungasebenzi ukuze kulungiswe futhi kufakwe ezinye esikhundleni sawo. Ngenxa yokuthi ama-air bearings awanayo izingxenye ezihambayo ezithintanayo, akukho ukuguguleka ezindaweni ze-granite. Uma nje umoya uhlala uhlanzekile futhi womile, uhlelo lokuthwala umoya we-granite lungagcina ukunemba kwalo kwefektri amashumi eminyaka.
Lokhu kuntuleka kokuguguleka kwenza lezi zinhlelo zilungele izindawo ezihlanzekile. Ama-bearings endabuko adinga amafutha noma uwoyela, angakhipha igesi noma alahle izinhlayiya, angcolise izingxenye ezibucayi ze-elekthronikhi noma ze-optical. Ama-bearings omoya “ahlanzekile” ngokwemvelo, aqeda umoya ohlungiwe kuphela. Lokhu kuwenza abaluleke kakhulu ekukhiqizweni kwama-microchip, izibonisi zamaphaneli ayisicaba, kanye namadivayisi ezokwelapha lapho ngisho nechashaza elilodwa lothuli lingaba yinhlekelele khona.
Indima Yokugoqa Ngesandla Ekuqondeni Kwanamuhla
Naphezu kokuthuthuka kokugaya nokupholisha kwe-CNC, izinga lokugcina lokunemba kwezindlela ze-granite ezenziwe ngokwezifiso livame ukudinga ukuthintwa ngumuntu. Ochwepheshe abangochwepheshe basebenzisa inqubo ebizwa ngokuthi i-hand-lapping ukuze bafinyelele ukuqina kokugcina kwe-sub-micron. Ngokusebenzisa ama-diamond abrasives namathuluzi okulinganisa akhethekile, bangabona futhi basuse izindawo eziphakeme ezincane ezingase zingatholakali yimishini.
Leli zinga lobuciko liqinisekisa ukuthi ifilimu yomoya ihlala ifana kulo lonke ubude bohambo. Uma isitimela se-granite singalingani ngokuphelele, igebe lomoya lizohluka, okubangela izinguquko ekuqineni kanye "nokuma" okungenzeka kwebhereyi. Umshado wokuqeda ngesandla kwendabuko kanye nokuguquguquka koketshezi kwesimanje yilokho okuvumela izindlela zokuthwala umoya we-granite ngokwezifiso ukufeza ukubekezelelana okukhulu kwejometri okudingekayo ekulawuleni ukunyakaza kwesizukulwane esilandelayo.
Ukuhlanganiswa nobuchwepheshe bezimoto eziqondile
Ukuze kusetshenziswe ngokugcwele izinzuzo zendlela ye-granite engenasiphazamiso, lezi zinhlelo cishe zihlala zihambisana nezinjini eziqondile. Ngokungafani nezikulufo zebhola, ezethula ukudlidliza komshini kanye nokubuyela emuva, izinjini eziqondile zihlinzeka ngokuqhutshwa okungenakuthintana. Uma injini engeyona ethintana ihlanganiswa nomoya ongenayo ethintana esisekelweni se-granite esizinzile, umphumela uba uhlelo lokunyakaza olungenayo i-hysteresis yomshini.
Le nhlanganisela ivumela ukusheshisa okuphezulu kakhulu kanye nezikhathi ezimfushane zokuxazulula. Ezimbonini ezifana nokuhlanganiswa kwe-elekthronikhi, lapho imishini kufanele inyakaze, ime, futhi iqalise isenzo izikhathi eziyizinkulungwane ngehora, ikhono lokuhlala endaweni eqondiwe ngaphakathi kwama-nanometer ngama-millisecond ambalwa lishintsha umdlalo we-throughput kanye ne-yield.
Isiphetho: Ukutshala imali esikhathini esizayo sesinyathelo
Ukushintshela ezindleleni zokuthwala umoya we-granite ngokunemba okwenziwe ngokwezifiso akuyona nje into eyenzeka; kuyinguquko edingekayo yezimboni ezisebenza ngaphansi kwemingcele engokwenyama. Ngenkathi ukutshalwa kwezimali kokuqala kuma-granite asezingeni eliphezulu kanye nama-air bearings ahambisana nokunemba kuphakeme kunezindlela zensimbi zendabuko, izindleko eziphelele zobunikazi—uma kucatshangelwa ukuntuleka kokuguguleka, ukugcinwa okuncishisiwe, kanye nesivuno esihle—kwenza kube ukukhetha okungabizi kakhulu kobunjiniyela obunezinzuzo eziphezulu.
Njengoba singena shí enkathini ye-nanotechnology kanye nokuzisebenzela ngesivinini esikhulu, ukuzinza kwe-granite kanye nobuhle bobuchwepheshe befilimu yomoya kuzoqhubeka nokuba yisisekelo lapho kwakhiwe khona imishini enembile kakhulu emhlabeni. Konjiniyela nabaklami bezinhlelo, ukwazi kahle ukusetshenziswa kwalezi zindlela ezenziwe ngokwezifiso kuyisihluthulelo sokuvula izinga elilandelayo lokusebenza kokulawula ukunyakaza.
