Mu dziko la kayendetsedwe ka kayendedwe kolondola kwambiri, pali chinthu chomwe chimachita chinthu chomwe chimamveka ngati chosatheka: gawo lolondola lomwe likuyandama pa filimu ya mpweya wokhuthala pang'ono, likuyenda popanda kukangana konse. Izi si nkhani za sayansi. Ndi granite air bearing—ndipo ndi ukadaulo wothandiza kumbuyo kwa semiconductor lithography, wafer inspection, EV battery inspection, ndi pafupifupi ntchito zina zonse zomwe zimafuna nanometer-level positioning.
Kodi Mpweya Wonyamula Zinthu Ndi Chiyani?
Mpweya wonyamula mpweya umagwira ntchito pokakamiza mpweya wopanikizika kudutsa pamalo oboola kapena odzaza ndi mpweya, ndikupanga mpweya wochepa, wopitilira pakati pa malo awiri omwe akanakhala ogwirizana. Katunduyo—siteji, spindle, tebulo loyenda—amayandama pa filimuyi ya mpweya, nthawi zambiri pakati pa maikuloni 5 ndi 20, kutengera kapangidwe ndi zofunikira pa katunduyo.
Popeza palibe kukhudzana kwenikweni pakati pa malo osuntha ndi osasuntha, palibe kukangana kwa makina, palibe kutsetsereka kwa ndodo, ndipo kwenikweni palibe kuwonongeka. Izi ndi zosiyana kwambiri ndi zomwe zikuchitikachogwirira chamakina chachizolowezi, yomwe—kaya ipangidwa bwino bwanji—nthawi zonse imakhala ndi kukangana pang'ono, kusakhazikika kwa pamwamba pa chinthucho, komanso kuwonongeka pang'onopang'ono pa nthawi yonse yogwira ntchito.
Chifukwa Chake Granite Ndi Chosankha Chokhacho cha Ma Air Bearings
Ma bearing a mpweya amatha kumangidwa pa zipangizo zosiyanasiyana zolimba komanso zosalala, koma granite yakhala chisankho chodziwika bwino cha malo osungira zinthu osasuntha pogwiritsa ntchito njira yolondola kwambiri.
Kukhazikika Kosalala Pakapita Nthawi. Popeza granite ili ndi mphamvu yochepa kwambiri mkati poyerekeza ndi chitsulo chopangidwa ndi makina—chitsulocho chimasunga mphamvu yotsala kuchokera ku njira yopangira ndi kupangira, zomwe zingayambitse kusintha pang'onopang'ono, pang'onopang'ono, kwa miyezi kapena zaka—malo oikira granite nthawi zambiri amakhala ndi mawonekedwe ake osalala kwa nthawi yayitali kuposa chitsulo chofanana nacho. Pa chitsulo choyikira mpweya, komwe mphamvu yonse yogwirira ntchito imadalira kusunga mpata wokhazikika, wolamulidwa, kukhazikika kumeneku ndikofunikira kwambiri.
Kukhazikika kwa Kutentha. Mpata woperekera mpweya ndi wochepa kwambiri—nthawi zambiri umakhala ma microns 5–20. Kukula kwa kutentha kwa njanji yowongolera kumasintha mpata uwu, kusintha magwiridwe antchito a bearing ndikuyambitsa zolakwika pakuyika. CTE ya Granite ndi pafupifupi theka la chitsulo ndi gawo limodzi mwa magawo atatu la aluminiyamu. Izi zimatsimikizira kuti kulondola kwa malo operekera mpweya ndi nanometer kumakhala koona pakatha maola 24.
Kuchotsa Madzi ndi Kugwedezeka. Granite ili ndi mphamvu yachilengedwe yochotsa madzi kupitirira nthawi 10 kuposa chitsulo. Ikaphatikizidwa ndi kusungunuka kwa filimu ya mpweya, dongosololi limapanga mphamvu ya "kuchotsa madzi kuwirikiza kawiri" yomwe imalekanitsa katundu wovuta kuchokera ku kugwedezeka kwa pansi ndi phokoso la injini. Izi ndizofunikira kwambiri pa ntchito monga mizati ya ma electron beam ndi interferometers, komwe kugwedezeka kumawononga mawonekedwe a chithunzi.
Simaginito, Simagwiritsidwe Ntchito Pamagetsi. M'malo opangira zinthu zamagetsi ndi zamagetsi, kupewa mphamvu zamaginito ndi kuyendetsa magetsi pafupi ndi njira zovutirapo nthawi zambiri kumakhala kovuta. Granite imakwaniritsa izi popanda chithandizo china chilichonse.
Zotsatira za "Kuchepetsa Kawiri"
Izi ndi zomwe zimapangitsa kuti kuphatikiza kwa granite ndi mpweya kukhale kogwira mtima kwambiri. Granite yokha imapereka chinyezi chapadera—kuchepetsa phokoso la makina ndi nthawi 10 poyerekeza ndi chitsulo chopangidwa ndi chitsulo. Filimu ya mpweya imapereka chinyezi chowonjezera champhamvu, kuyeretsa kugwedezeka kwamphamvu. Pamodzi, amapanga zomwe mainjiniya amatcha "kusungunuka kawiri".
Izi zikutanthauza kuti gawo lokhala ndi mpweya wa granite silili lolondola kokha; ndi chete. Gawolo limayenda bwino, popanda kugwedezeka kwa microscopic komwe kumavutitsa ma bearing a makina. Limakhazikika mwachangu, popanda kulira komwe kungachedwetse kuyeza. Ndipo limasunga kulondola kwake kwa zaka zambiri likugwira ntchito, popanda kuwonongeka pang'onopang'ono komwe kumawononga magwiridwe antchito a ma bearing a makina.
Kumene Ma Granite Air Bearings Amagwiritsidwa Ntchito Kwenikweni
Mndandanda wa ntchito umaoneka ngati ulendo wowona mbali zolondola kwambiri zopangira ndi kuwunika zamakono:
Kuyang'anira Ma Semiconductor Lithography ndi Wafer. Kubwerezabwereza kwa malo a sub-nanometer ndikofunikira kuti zinthu zigwirizane bwino ndi wafer. Ma granite air bearing amapereka kayendedwe kopanda kukangana, kosakhudzana komwe kumalola kulondola kofunikira popanga ma chip a m'badwo wotsatira.
Makina Oyezera Ogwirizana (CMMs). Kuphatikiza kwa malangizo a granite olondola ndi ma bearing a mpweya ndiye muyezo wabwino kwambiri wa ma CMM, pomwe kugwedezeka kwa siteji kumawononga kutsimikiza kwa muyeso. Kusakhalapo kwa bearing ya mpweya ndi kutsetsereka kwa ndodo kumathandiza kuyika malo mu nanometer increments.
Machitidwe Oyezera Ogwiritsa Ntchito Laser ndi Optical. Dongosolo lililonse loyezera lomwe limagwiritsa ntchito interferometry kapena optical imaging limafuna gawo loyenda lomwe silimayambitsa vuto la kugwedezeka kapena malo. Ma granite air bearing amapereka kukhazikika kofunikira pa ntchito zovuta izi.
Kuyang'anira Mabatire a EV. Pamene kupanga mabatire a magalimoto amagetsi kukukulirakulira, kufunikira kwa makina owunikira othamanga kwambiri komanso olondola kwambiri kwakula kwambiri. Gawo lonyamula mpweya wa granite limapereka liwiro ndi kulondola kofunikira poyang'ana kukula kwa selo ya batri, kulumikizana kwa ma electrode, ndi zina zofunika kwambiri.
Kuboola ndi Kuyendetsa Ma PCB. Kuboola PCB mwachangu kwambiri kumafuna malo ofulumira komanso olondola komanso nthawi yochepa yokhazikika. Ma bearing a mpweya amalola kuyenda mwachangu komanso kokhazikika komwe kumafunikira kuti pakhale mphamvu zambiri.
Zomwe Zimapangitsa ZHHIMG® Kukhala Yosiyana
Sizigawo zonse zonyamulira mpweya wa granite zomwe zimapangidwa mofanana. Ubwino wa granite, kulondola kwa kulumikiza, ndi luso la amisiri zonse zimatsimikizira ngati chonyamulira mpweya chikugwira ntchito molingana ndi zomwe zafotokozedwa.
Ku ZHHIMG®, granite yathu yakuda ya ZHHIMG® imapeza kuchuluka kwa ≈3100 kg/m³—kokwera kuposa granite zambiri zakuda zaku Europe ndi America—kutsimikizira kukhazikika kwapamwamba komanso kukana kuwonongeka. Makina athu opukusira, omwe akhala ndi zaka zoposa 30 akugwira ntchito yopukusira ndi manja, amakwaniritsa kusalala kwa nanometer komwe kumafunikira kuti agwiritsidwe ntchito ponyamula mpweya. Malo athu ogwirira ntchito otentha okwana masikweya mita 10,000, omangidwa pa maziko a konkriti wolimba kwambiri wa 1000mm wokhala ndi ngalande zoteteza kugwedezeka za 2000mm, amapereka malo okhazikika ofunikira popanga zinthu zolondola izi.
Ndipo kudzipereka kwathu ku khalidwe labwino—komwe kwafotokozedwa mu ndondomeko yathu ya khalidwe labwino, “Bizinesi yolondola singakhale yovuta kwambiri”—kumatsimikizira kuti gawo lililonse la granite air bearing lomwe likutuluka m'malo mwathu likukwaniritsa miyezo yofunika kwambiri padziko lonse lapansi.
Kaya mukupanga mbadwo wotsatira wa zida za semiconductor lithography, CMM yolondola kwambiri, kapena makina owunikira mabatire a EV, kuphatikiza kwa granite yolondola ndi ukadaulo wonyamula mpweya kumapereka maziko owongolera kayendedwe ka nanometer. Ndipo ku ZHHIMG®, takhala tikudziwa bwino kuphatikiza kumeneku kwa zaka zambiri.
