Mukutsvaga kusingaperi kwe nanometer-scale accuracy, maindasitiri ekugadzira uye semiconductor akawedzera kutsauka kubva kuma mechanical bearings echinyakare kuenda kune mhinduro yakanyanya kunaka: nzira dze granite air bearing. Sezvo michina ichikurumidza uye zvinodiwa zvekugadzirisa zvichiwedzera kuoma, miganhu ye contact-based motion systems—yakadai sekukweshana, kupera, uye kupisa—yave miganhu yakakosha. Granite air bearings yakagadzirwa nemaitiro anomiririra shanduko yeparadigm, ichibatanidza kugadzikana kwe geological kwematombo echisikigo nekushanda pasina kukweshana kwetekinoroji ye air film yakamanikidzwa kutsanangura patsva miganhu yekushanda kwekudzora kufamba.
Kubatana kweZvinhu zvechisikigo uye Simba remvura
Pakati pemasystem aya anoshanda zvakanyanya pane kusanganiswa kwegranite nhema nemabheringi emhepo. Granite ndiyo substrate inonyanya kufarirwa nekuda kwehunhu hwayo hunoshamisa hwepanyama. Kusiyana nesimbi, granite inokura kwemamiriyoni emakore, zvichikonzera zvinhu zvisina kumanikidzwa mukati. Ine coefficient yakaderera yekuwedzera kwekupisa uye kugona kwakanyanya kwekudzima vibration. Kana hwaro uhwu hwakagadzikana hwakabatana kusvika pakadzika zvakanyanya—kazhinji kacho hunoyerwa muzvikamu zve micrometer—inova nzira yakakwana yekufambisa mhepo.
Nzira yekufambisa mweya inoshanda nekutsigira mutoro uri pafirimu rakatetepa remhepo yakamanikidzwa, kazhinji inotangira pama micrometer mashanu kusvika gumi pakukora. Nekuti hapana kubatana kwepanyama pakati pengoro inofamba negranite rail, chiyero chekukweshana chinonyatsoita zero pakutanga kwekufamba. Izvi zvinobvisa chiitiko che "stick-slip" chinowanzoitika mumasisitimu emakanika, zvichibvumira shanduko dzakapfava, nekukurumidza uye nzvimbo yakanaka kwazvo iyo ma mechanical rollers asingagoni kuita.
Kugadzirisa: Kugadzirisa Fizikisi Kuenderana Nekushandisa
Kunyange zvazvo zvinhu zvisiri zvemazuva ano zviripo, simba rechokwadi re tekinoroji iyi rinowanikwa kuburikidza nekugadzira mainjiniya akagadzirwa neunyanzvi. Chero nzira yekushanda yepamusoro, ingave system yekuongorora wafer kana nzvimbo ye laser machining inokurumidza, ine zvinodiwa zvakasiyana zvekukwanisa kutakura, kuomarara, uye kureba kwekufamba. Kugadzirisa mageometry enzira dzegranite kunobvumira mainjiniya kugadzirisa "bearing footprint" kusvika pahuremu hwemutoro.
Kugadzirisa zvinhu kunosanganisirawo kubatanidzwa kwe vacuum-preloading. Muzvishandiso zvakawanda zvine hungwaru, mabearing emhepo akagadzirwa ane ma vacuum ports emukati anokwevera ngoro kuenda pamusoro pe granite ukuwo kumanikidzwa kwemhepo kuchiisundira kure. "Simba rinopikisa" iri rinogadzira firimu remhepo rakasimba kwazvo rinogona kudzivirira masimba ekunze uye kudedera, zvichiita kuti kufamba kurambe kwakarongeka uye kwakasimba kunyangwe kana paine kumhanya kwakasiyana kana shanduko dzedivi. Nekugadzirisa vacuum uye kuenzana kwekumanikidzwa, vagadziri vanogona kugadzirisa kuomarara kwesystem kuti kuenderane nema frequency e resonant enzvimbo chaiyo.
Kukunda Matambudziko Ekukakavadzana Nekupisa
Munzira dzechinyakare dzekufamba, kukweshana ndiko muvengi wekusagadzikana. Kukweshana kunounza kupisa, uye kupisa kunoita kuti zvikamu zvemakanika zviwedzere, zvichikonzera kutsvedza kwenzvimbo. Mumaitiro ekugadzira anotora nguva refu, kunyangwe kukwira kudiki kwekushisa kunogona kukanganisa huwandu hwezvikamu zvakanyatsonaka.
Nzira dzekugadzira mhepo yegranite dzakanyatsogadzirwa dzinogadzirisa izvi nekubvisa kwainobva kupisa. Pasina zvinhu zvinotenderera kana kukweshana kunotsvedza, hapana kuunganidza kwekupisa mukati mebearing pachayo. Uyezve, kuyerera kwemhepo yakamanikidzwa kuburikidza nebearing kunoshanda senzira yekutonhodza iri munzvimbo, zvichiwedzera kugadzikana kwenharaunda. Kusapindirana kwekupisa uku ndiko kwakakosha pakuita kuti mabearing emhepo ave chiyero cheindasitiri chemichina yekuyera coordinate (CMMs) uye optical lithography stages, uko kuwedzera kudiki kunogona kukonzera zvikanganiso zvakakura zvedata.
Kugara kwenguva refu uye kuchena munzvimbo dzakadzorwa
Chimwe chezvinhu zvinonyanya kukosha pakushandisa nzira dzekugadzira mhepo yegranite ndechekuti dzinoshanda kwenguva yakareba sei. Muhurongwa hwekugadzira mhepo yegranite, zvikamu zvinopedzisira zvaneta, maroller anokanganisika, uye mafuta anozora kana kusvibiswa. Izvi zvinoda nguva yekushanda kuti zvigadziriswe uye pakupedzisira zvigadziriswe. Nekuti mabheyaringi emhepo haana zvikamu zvinofamba zvinosangana, hapana kupera kwegranite pamusoro. Chero bedzi mhepo inoramba yakachena uye yakaoma, hurongwa hwekugadzira mhepo yegranite hunogona kuchengetedza kururama kwayo kwemakumi emakore.
Kusapfekwa uku kunoitawo kuti masisitimu aya akwane munzvimbo dzakachena. Mabheyaringi echinyakare anoda mafuta kana mafuta, izvo zvinogona kubvisa gasi kana kubvisa zvidimbu, zvichisvibisa zvikamu zvemagetsi kana zvemaziso. Mabheyaringi emhepo "akachena" zvakasikwa, anopedza mweya wakasefetwa chete. Izvi zvinoita kuti ave akakosha mukugadzirwa kwema microchips, flat-panel displays, uye zvishandiso zvekurapa uko kunyange kaguruva kadiki kanogona kukonzera njodzi.
Basa reKubata Maoko Nemaoko Mumazuva Ano Akanyatsojeka
Pasinei nekufambira mberi kweCNC grinding and polishing, nhanho yekupedzisira yekunyatsorongeka kwenzira dzegranite dzakagadzirwa inowanzoda kubata kwevanhu. Nyanzvi dzehunyanzvi dzinoshandisa nzira inonzi hand-lapping kuti dzisvike padanho rekupedzisira re sub-micron flatness. Nekushandisa madhaimani abrasives uye maturusi ekuyera akasarudzika, vanogona kuona nekubvisa nzvimbo dzakakwirira dzisingaonekwe nemicroscope dzingasaonekwa nemashini.
Unyanzvi uhwu hunovimbisa kuti firimu remhepo rinoramba rakafanana panguva yese yekufamba. Kana njanji yegranite isina kutsetseka zvakakwana, mukaha wemhepo unosiyana, zvichikonzera shanduko mukuomarara uye "kudzika" kwebheya. Kubatanidzwa kwekugadzirwa kwemaoko nemaoko uye kushanduka kwemvura kwemazuva ano ndiko kunobvumira nzira dzekugadzira bheya regranite kuti dzisvike pakukwanisa kwakanyanya kwejometri kunodiwa pakudzora kufamba kwechizvarwa chinotevera.
Kubatanidzwa neLinear Motor Technology
Kuti zvinyatsobatsira nzira yegranite isina kukweshana, masisitimu aya anowanzo batanidzwa nemamota ane mutsara. Kusiyana nemasikuruu ebhora, ayo anounza kugwinha kwemuchina uye backlash, mamota ane mutsara anopa simba risingabatanidzi. Kana mota isina kubatana ikabatanidzwa nemhepo isina kubatana pachigadziko chegranite chakagadzikana, mhedzisiro yacho isystem yekufamba isina hysteresis yemuchina.
Musanganiswa uyu unobvumira kukurumidza kwakanyanya uye nguva pfupi yekugadzikana. Mumaindasitiri akadai sekugadzira zvemagetsi, uko michina inofanira kufamba, kumisa, uye kutanga chiito kanopfuura zviuru paawa, kugona kugara panzvimbo yakatarwa mukati menanometers mumamiliseconds mashoma kunochinja mutambo we throughput uye goeth.
Mhedziso: Kuisa Mari Muramangwana Rekufamba Kwezvinhu
Kuchinja kwenzira dzekugadzira mhepo yegranite chaiyo hakusi kungoitika chete; inyaya yekushanduka-shanduka kunodiwa kumaindasitiri anoshanda ari pamucheto wemiganhu yemuviri. Kunyange hazvo mari yekutanga mukugadzira granite yepamusoro uye mabheyaringi emhepo akanyatsogadzirwa yakakwira kupfuura yesimbi dzekare, mutengo wese wekuva muridzi wayo—tichifunga nezvekusasakara, kuderedzwa kwekugadzirisa, uye goho rakanaka—zvinoita kuti ive sarudzo inodhura zvishoma kune mainjiniya ane hunyanzvi hwepamusoro.
Sezvatinopinda mukati menguva ye nanotechnology uye otomatiki inokurumidza zvikuru, kugadzikana kwegranite uye runako rwetekinoroji yemhepo zvicharamba zviri hwaro hwakavakirwa michina yakanyatsonaka pasi rose. Kune mainjiniya nevagadziri vemasystem, kugona kushandisa nzira idzi dzakasarudzika ndiyo kiyi yekuvhura nhanho inotevera yekushanda kwekudzora kufamba.
