Pofuna kutsata mosalekeza kulondola kwa nanometer-scale, makampani opanga ndi opanga ma semiconductor asiya kugwiritsa ntchito mabearing achikhalidwe kupita ku njira yowonjezereka: njira zoyendetsera mpweya wa granite molondola. Pamene makina akukhala othamanga ndipo zofunikira zolondola zikukhwima, zolepheretsa za kayendedwe kogwirizana ndi kukhudzana—monga kukangana, kuvala, ndi kupanga kutentha—zakhala zopinga zazikulu. Mabearing a mpweya wa granite opangidwa mwapadera akuyimira kusintha kwa njira, kuphatikiza kukhazikika kwa miyala yachilengedwe ndi mphamvu yopanda kukangana ya ukadaulo wa mafilimu a mpweya wopanikizika kuti afotokozenso malire a magwiridwe antchito owongolera kuyenda.
Kugwirizana kwa Zinthu Zachilengedwe ndi Mphamvu Zamadzimadzi
Pakati pa machitidwe ogwirira ntchito bwino awa pali kuphatikiza kwa granite wakuda ndi ma bearing a aerostatic. Granite ndiye substrate yomwe imakondedwa kwambiri chifukwa cha mawonekedwe ake apadera. Mosiyana ndi zitsulo, granite imakalamba mwachilengedwe kwa zaka mamiliyoni ambiri, zomwe zimapangitsa kuti ikhale yopanda kupsinjika kwamkati. Ili ndi coefficient yochepa ya kutentha komanso mphamvu yayikulu yochepetsera kugwedezeka. Pamene maziko okhazikika awa alumikizidwa mpaka kuphwanyika kwambiri - nthawi zambiri amayesedwa m'zigawo za micrometer - imakhala njira yoyenera yoyendetsera ndege.
Njira yonyamulira mpweya imagwira ntchito pothandizira katundu pa filimu yopyapyala ya mpweya wopanikizika, nthawi zambiri imakhala yolemera kuyambira ma micrometer 5 mpaka 10. Chifukwa palibe kukhudzana kwenikweni pakati pa ngolo yoyenda ndi njanji ya granite, coefficient ya friction imakhala zero kwenikweni poyambira kuyenda. Izi zimachotsa zomwe zimachitika "monga ndodo" zomwe zimachitika m'makina, zomwe zimapangitsa kuti kusintha kosalala, nthawi yomweyo komanso malo abwino kwambiri omwe ma mechanical rollers sangathe kuchita.
Kusintha: Kusintha Fiziki kuti Igwiritsidwe Ntchito
Ngakhale kuti pali zinthu zomwe sizikugwiritsidwa ntchito kale, mphamvu yeniyeni ya ukadaulo uwu imapezeka kudzera mu uinjiniya wolondola kwambiri. Ntchito iliyonse yapamwamba, kaya ndi makina owunikira a wafer kapena malo opangira laser othamanga kwambiri, ili ndi zofunikira zapadera pakukula kwa katundu, kuuma, ndi kutalika kwa ulendo. Kusintha mawonekedwe a njira za granite kumathandiza mainjiniya kukonza "malo onyamulira" kuti agwirizane ndi kulemera kwa katundu wolipidwa.
Kusintha kumaphatikizaponso kuphatikiza vacuum-preloading. Mu makonzedwe ambiri olondola kwambiri, ma air bearing amapangidwa ndi ma vacuum ports amkati omwe amakoka galimotoyo kupita pamwamba pa granite pomwe mpweya ukuikakamiza. "Mphamvu yotsutsana" iyi imapanga filimu yolimba kwambiri ya mpweya yomwe imatha kukana mphamvu zakunja ndi kugwedezeka, kuonetsetsa kuti mayendedwewo amakhalabe olunjika komanso okhazikika ngakhale pansi pa liwiro losiyanasiyana kapena kusintha kwa mbali. Mwa kusintha vacuum ndi kuthamanga bwino, opanga amatha kusintha kuuma kwa makinawo kuti agwirizane ndi ma frequency omveka bwino a malo enieni.
Kuthana ndi Mavuto Okhudzana ndi Kukangana ndi Kutentha
Mu machitidwe oyendera achikhalidwe, kukangana ndi mdani wa kusasinthasintha. Kukangana kumabweretsa kutentha, ndipo kutentha kumapangitsa kuti zigawo zamakina zikule, zomwe zimapangitsa kuti malo azisinthasintha. Mu njira zopangira zinthu nthawi yayitali, ngakhale kukwera pang'ono kwa kutentha kumatha kuwononga gulu la zigawo zolondola kwambiri.
Njira zoyendetsera mpweya wa granite moyenera zimathetsa vutoli pochotsa komwe kumachokera kutentha. Popanda zinthu zozungulira kapena kugwedezeka kotsetsereka, palibe kusungunuka kwa kutentha mkati mwa bearing yokha. Kuphatikiza apo, kuyenda kosalekeza kwa mpweya wopanikizika kudzera mu bearing kumagwira ntchito ngati njira yozizira yapafupi, ndikulimbikitsa chilengedwe. Kusalowerera kwa kutentha kumeneku ndi chifukwa chake ma bearing a mpweya ndi muyezo wamakampani a makina oyezera ogwirizana (CMMs) ndi magawo a optical lithography, komwe kukulitsa pang'ono kungayambitse zolakwika zazikulu za data.
Kulimba ndi Ukhondo m'malo olamulidwa
Chimodzi mwa zifukwa zomveka kwambiri zogwiritsira ntchito njira zoyendetsera mpweya wa granite ndi moyo wawo wopanda malire. Mu makina oyendetsera mpweya, ziwalo pamapeto pake zimatopa, ma rollers amawonongeka, ndipo mafuta amawonongeka kapena kuipitsidwa. Izi zimafuna nthawi yogwira ntchito yokonza ndikusintha. Chifukwa ma air bearing alibe ziwalo zosuntha zomwe zimalumikizana, palibe kuwonongeka ndi kuwonongeka pamwamba pa granite. Bola ngati mpweya umakhalabe woyera komanso wouma, makina oyendetsera mpweya wa granite amatha kusunga kulondola kwa fakitale yake kwa zaka zambiri.
Kusawonongeka kumeneku kumapangitsanso kuti makinawa akhale abwino kwambiri m'malo oyeretsera. Maberiyani achikhalidwe amafuna mafuta kapena mafuta, omwe amatha kutulutsa mpweya kapena kutaya tinthu tating'onoting'ono, zomwe zimadetsa zinthu zamagetsi kapena zowunikira. Maberiyani a mpweya ndi "oyera" mwachibadwa, omwe amangotopetsa mpweya wosefedwa. Izi zimapangitsa kuti akhale ofunikira kwambiri popanga ma microchip, ma flat-panel displays, ndi zida zamankhwala komwe ngakhale kachidutswa kakang'ono ka fumbi kangakhale koopsa.
Udindo wa Kugwirana ndi Manja mu Kulondola Kwamakono
Ngakhale kuti CNC yapita patsogolo pogaya ndi kupukuta, njira yomaliza yolondola yopangira granite nthawi zambiri imafuna kukhudza kwa munthu. Akatswiri aukadaulo amagwiritsa ntchito njira yotchedwa hand-lapping kuti akwaniritse kusalala kwa sub-micron komaliza. Pogwiritsa ntchito diamond abrasives ndi zida zapadera zoyezera, amatha kuzindikira ndikuchotsa malo okwera a microscopic omwe makina angaphonye.
Luso limeneli limatsimikizira kuti filimu ya mpweya imakhalabe yofanana nthawi yonse yoyenda. Ngati njanji ya granite siili yosalala bwino, kusiyana kwa mpweya kumasiyana, zomwe zimapangitsa kuti kuuma kwake kusinthe komanso "kukhazikika" kwa bearing. Kugwirizana kwa njira zachikhalidwe zomaliza ndi manja komanso mphamvu zamakono zamadzimadzi ndizomwe zimapangitsa kuti bearing ya granite yapangidwe kuti ikwaniritse kulekerera kwakukulu komwe kumafunikira pakulamulira kayendedwe ka m'badwo wotsatira.
Kuphatikiza ndi Linear Motor Technology
Kuti agwiritse ntchito bwino ubwino wa njira ya granite yopanda kukangana, machitidwe awa nthawi zambiri amagwirizanitsidwa ndi ma motors olunjika. Mosiyana ndi zomangira za mpira, zomwe zimayambitsa kugwedezeka kwa makina ndi kugwedezeka kumbuyo, ma motors olunjika amapereka mphamvu yosakhudzana. Pamene mota yosakhudzana ikaphatikizidwa ndi mpweya wosakhudzana ndi maziko a granite okhazikika, zotsatira zake zimakhala makina oyenda opanda hysteresis ya makina.
Kuphatikiza kumeneku kumalola kuti zinthu ziziyenda mofulumira kwambiri komanso kuti nthawi yokhazikika ikhale yochepa. M'mafakitale monga kusonkhanitsa zamagetsi, komwe makina ayenera kusuntha, kuyimitsa, ndikuyambitsa chinthu nthawi zambiri pa ola limodzi, kuthekera kokhazikika pamalo omwe akufuna mkati mwa nanometers mu ma milliseconds ochepa ndi njira yosinthira mphamvu ndi phindu.
Kutsiliza: Kuyika Ndalama Patsogolo pa Kusuntha
Kusintha kwa njira zopangira mpweya wa granite wolondola sikuti ndi chizolowezi chokha; ndi kusintha kofunikira kwa mafakitale omwe amagwira ntchito mopitirira malire enieni. Ngakhale kuti ndalama zoyamba zopangira granite yapamwamba komanso ma bearings a mpweya wolondola ndi okwera kuposa a njanji zachitsulo zachikhalidwe, mtengo wonse wa umwini—poganizira kusawonongeka, kuchepa kwa kukonza, komanso kukolola kwakukulu—kumapangitsa kuti ikhale chisankho chotsika mtengo kwambiri kwa mainjiniya olemera.
Pamene tikulowa mkati mwa nthawi ya nanotechnology ndi automation yothamanga kwambiri, kukhazikika kwa granite ndi kukongola kwa ukadaulo wa air-film zidzapitirira kukhala maziko omwe makina olondola kwambiri padziko lonse lapansi amamangidwira. Kwa mainjiniya ndi opanga makina, kudziwa bwino kugwiritsa ntchito njira izi ndi chinsinsi chotsegula gawo lotsatira la magwiridwe antchito owongolera kuyenda.
