Ama-air bearing afinyelela lokho okungafinyelelwa yi-contact bearing: ukunyakaza ngaphandle kokuguga, ngaphandle kokunamathela futhi ngaphandle kokugcoba, emazingeni aphansi kwe-micron. Kodwa i-air bearing ilingana kuphela nendawo entanta kuyo. Lesi sihloko sichaza i-physics yamafilimu omoya, ukuthi kungani i-granite yemvelo enemibala emihle iyinto efanele yokuhlangana, ukuthi ukunemba kobuso okudingwa umzila wesitimela kukuphi, nokuthi izigaba ze-granite air bearing ziletha kuphi inani elikhulu - kusukela kumapulatifomu e-linear motor kuya ezinhlelweni zokuhlola ze-optical.
1. Indlela Ama-Air Bearings Asebenza Ngayo: Ukugibela Ifilimu Yomoya Encane Kancane
I-air bearing isekela umthwalo wayo efilimini encane ecindezelwe, ngokuvamile ubukhulu obungu-3–15 µm. Izimiso ezimbili zokuphakelwa zibusa:
- Isinxephezelo se-orifice.Umoya ugeleza ngemigodi enobukhulu obuqondile uye ephaketheni noma emseleni ongajulile; ingcindezi iyazilungisa ngokwayo njengoba igebe lishintsha. Kulula futhi kuqinile, kodwa umthamo womthwalo ulinganiselwe futhi ifilimu iyazwela emaphutheni ongaphezulu kwendawo.
- Isinxephezelo esingenazo izimbobo.Umoya uphuma igazi ngokulinganayo entweni enezimbobo (ngokuvamile ikhabhoni), okwenza ifilimu eqinile futhi ebekezelela ukuthambekela enomswakama ophezulu.
Noma ngabe yikuphi, i-physics ebusayo iyafana: ukuqina kwefilimu kuncike esikweleni sokufana kwegebe. Uma ubuso bomzila bunokuguquguquka okufana nobukhulu befilimu, isiteji sibhekana nokuguquguquka kwengcindezi — okubonakala njengephutha lokuqondisa, ukugoqa, noma okubi nakakhulu, isando somoya (ukushukuma okuzijabulisayo).Umzila, hhayi i-bearing, ubeka uphahla lwekhwalithi yesistimu.
2. Kungani iGranite Iyindlela Efanele Yokuqondisa
Onjiniyela ngezinye izikhathi babuza ukuthi kungani izigaba zokuthwala umoya zigijima kakhulu kangaka phezu kwe-granite kunezinsimbi noma izinsimbi zobumba. Izizathu ziyi-physics yezinto ezibonakalayo, hhayi isiko:
- Isakhiwo esihle, esilinganayo sokusanhlamvu.I-granite emnyama ye-Igneous iyaqina kusukela ekuncibilikeni okukodwa; akukho ukuhlukaniswa kwe-dendritic, ukufakwa noma i-matrix ethambile njengasensimbini ephonswe. Ukuxhumanisa kuveza ubuso obufanayo, ngakho-ke igebe lomoya lihlala lifana phakathi nohambo lonke - into eyodwa ebaluleke kakhulu yokuqina kwefilimu.
- Ukwanda okuphansi kokushisa (≈5–8 µm/m·°C).Izikhala zomoya zingama-micron ambalwa nje; uhhafu wezinga lokushintsha kwezinga lokushisa ungaguqula isitimela sensimbi ngaphezu kwesikhala somoya. Ukuqina kwe-granite kugcina i-geometry yefilimu ingashintshi phakathi kwemijikelezo yasemini nasebusuku.
- Akukho ukugqwala, akukho uwoyela.I-granite engenalutho ayidingi ukumbozwa futhi ayidingi ukuthambisa — ibalulekile emakamelweni ahlanzekile, lapho ukuphuma kwegesi kanye nokukhiqizwa kwezinhlayiya kungafaneleki khona emigwaqweni egcotshwe ngamafutha.
- Ukushisa okuphezulu.Ukudambisa kwangaphakathi kweGranite kuvimbela ukudluliselwa kokudlidliza kusuka phansi nasemadrayivu, kuthuthukisa ukuziphatha okuguquguqukayo kwesigaba sokuntanta.
- Ingaguquguquka ibe yi-micron-level flatness ngaphezu kwamamitha.Izinsimbi zegranite ezinde zingaxhunywa ngesandla futhi ziqinisekiswe zibe ama-micron ambalwa ngaphezu kwamamitha amaningana — into engenakufezwa ukwenziwa kwemishini kuphela.
3. Yikuphi Ukunemba Komphezulu Okudingwa Yisiqondiso Sokuthwala Umoya?
Ukucaciswa kuncike ohlotsheni lwebhere kanye nekhwalithi yokunyakaza okuqondiwe, kodwa izidingo ezijwayelekile zokunembai-granite air bearinguhlelo luyi:
| Ipharamitha | Isidingo Esijwayelekile | Kungani Kubalulekile |
|---|---|---|
| Ubuso obuphelele bokuthwala | 1–5 µm ngaphezu kobude bokuhamba | Ukufana kwesikhala sefilimu eyisisekelo |
| Ukuthamba kwendawo / ukugoba | ≤ 0.5–1 µm ngama-25 mm | Amaphutha obude obufushane alawula ingcindezi ngqo |
| Ukuqondakala kokuhamba okugcwele | 0.5–2 µm (okuqondile nokuqondile) | Iphutha lokuqondisa kwesiteji ngqo |
| Ukuqeda kobuso | I-Lapped, i-Ra ≤ 0.4 µm ngokuvamile | Ukuqeda kuthinta ukuvuza kwegebe kanye nokuqina kokugeleza |
| Ukufana kwezindlela eziphikisanayo | 1–3 µm ubude | Izilawuli ziyagingqika futhi ziyakhala inqola |
Ukuqinisekiswa akuhlukaniseki kulezi zinombolo: ukulinganisa ukunemba phezu kwesitimela esingamamitha angu-2 ngokungaqiniseki kwe-sub-micron kudinga amazinga kagesi, ama-autocollimator noma i-laser interferometry ekamelweni elilawulwa izinga lokushisa. Yingakho ikhono lokulinganisa lomhlinzeki wendlela yokuqondisa libaluleke kakhulu njengamabhentshi abo okulala - sichaza indlela yethu ku-ukuhlolwa nokulinganiswa kwe-graniteinqubo.
4. Izicelo Ezijwayelekile
- Amapulatifomu enjini aqondile.Ama-motor angenazinsimbi aqondile anikeza amandla abushelelezi ngaphandle kokubopha; kuhlanganiswe nemigwaqo yomoya ye-granite, izigaba zifinyelela ukuqondeka kwe-sub-micron ngesivinini esingu-1–2 m/s — ukwakheka okujwayelekile kokuhlolwa kwe-wafer kanye nokuskena nge-laser.
- Izigaba zokunemba ze-XY.Izigaba zokuthwala umoya ezihlanganisiwe noma ezihleliwe esisekelweni segranite zifinyelela ukuphindaphindeka kwezinga le-nanometer kwe-lithography-metrology eseduze, amakhadi e-probe kanye nokuhlolwa kwesibonisi.
- Izinhlelo zokuhlola okubonakalayo.Izinhlelo zezinzwa ze-Confocal, interferometric kanye ne-chromatic zidinga ukunyakaza kokuskena okungenazidlidliza, okungenazo izigaxa; ifilimu engathintani ayifaki izinhlayiya futhi ayinayo i-hysteresis.
- Ama-comparators amaningi kanye nama-metrology lab.Izinqola ezithwala umoya ezirelini ze-granite zisebenza lapho kokubili ukuhlanzeka kanye nokuphelela kwejometri kuyimpoqo.
Kuzo zonke lezi zimo i-granite idlala izindima ezimbili ngesikhathi esisodwa: isisekelo sesakhiwo kanye nomhlahlandlela wokunemba. Ukuhlanganisa kokubili ezintweni ezilodwa — inqubo eyodwa yokugoqa, ukuziphatha kokushisa okukodwa, isitifiketi esisodwa — kususa izixhumi ezingasetshenziswa ukufaka iphutha. Imininingwane eyengeziwe yohlelo lokusebenza iyatholakala ku-imishini ye-semiconductorizixazululo.
5. Amanothi Okuklama Ngaphambi Kokuthi Ucacise
- Chaza ukuhamba, umthwalo kanye nendawo yokudonsa amandla adonsela phansi— ukuqina kwefilimu kanye nomthwalo wangaphambi kokuthwala kulinganiselwa nxazonke.
- Cacisa ikhwalithi yomoya— ngokuvamile umoya ohlanzekile, owomile onokuhluzwa okufika ku-0.01 µm; ifilimu ihlanzekile kuphela njengomthombo.
- Nquma idethi yokulinganisa— ubani ongumnikazi wereferensi yokuqondisa: umenzi wokuthwala, umenzi wesisekelo, noma uhlelo oluhlanganisiwe?
- Hlela indawo ezungezile— 20 ± 0.5 °C kanye nesisekelo esihlukanisiwe nokudlidliza kugcina i-geometry eqinisekisiwe.
- Cela umbiko wokuhlola kanye nengxenye— amanani okuqondile/okusicaba alinganiswe ngokuhlonza ithuluzi kanye nokulandelela, hhayi nje uhlamvu lwebanga.
Isiphetho
Ama-air bearings kanye ne-granite kuyahambisana: i-bearings inikeza ukunyakaza okungenamikhuhlane, kanti i-granite inikeza ubuso obuzinzile ngokwejiyometri, obuthule ngokwezinga lokushisa, obungenazinhlayiya ezenza ifilimu isebenze. Uma zombili ziklanywe futhi ziqinisekiswa ndawonye, umphumela uba yikhwalithi yokunyakaza izinhlelo zokuxhumana ezingenakukwazi ukuyifinyelela.
