Munyika yekudzora kufamba kwakanyatsojeka, kune chimwe chinhu chinoita chimwe chinhu chinoita sechisingagoneki: danho rekunyatsojeka riri pamusoro pefirimu remhepo ine ukobvu hwema microns mashoma, richifamba pasina kukweshana zvachose. Iyi haisi nyaya yesainzi. Imhepo ine granite—uye ndiyo tekinoroji inogonesa seri kwe semiconductor lithography, wafer inspection, EV battery inspection, uye zvimwe zvese zvinoda nanometer-level positioning.
Chii Chinonzi Mhepo Inotakura Zvinhu?
Mhepo inoshanda nekumanikidza mweya wakamanikidzwa kuti upfuure nepanzvimbo ine maburi kana kuti ine gomba, zvichiita kuti mhepo igare yakatetepa pakati penzvimbo mbiri dzaizosangana. Mutoro—danho, simende, tafura inofamba—inoyangarara pafirimu iyi yemhepo, kazhinji iri pakati pema microns mashanu nemakumi maviri pakukora, zvichienderana nekugadzirwa uye zvinodiwa nemutoro.
Nekuti hapana kubatana kwemuviri pakati penzvimbo dzinofamba nedzisingamire, hapana kukweshana kwemuchina, hapana maitiro ekutsvedza, uye hapana kusakara. Iyi mamiriro akasiyana zvachose neayabheyaringi yemakanika yakajairika, iyo—zvisinei nekuti yakagadzirwa zvakanaka sei—inogara iine kukweshana, kusarongeka kwepamusoro nepadiki, uye kupera zvishoma nezvishoma panguva yekushanda kwayo.
Nei Granite Ndiyo Chete Sarudzo Yemabheya Emhepo
Mabheyaringi emhepo anogona kuvakwa pazvinhu zvakasiyana-siyana zvakati sandara, zvakaoma, asi granite ndiyo yave sarudzo yakajairika yenzvimbo yebheyaringi isingachinji mumashandisirwo akanyatsojeka.
Kugadzikana Kwekutsetseka Nekufamba Kwenguva. Nekuti granite ine kushushikana kwemukati kwakaderera zvakanyanya kana tichienzanisa nesimbi yakagadzirwa nemuchina—simbi inoramba iine kushushikana kwakasara kubva mukuita kwekukanda nekugadzira, izvo zvinogona kukonzera kuchinja kudiki-diki, zvishoma nezvishoma kwemwedzi kana makore—pamusoro pegranite bearing surface inowanzo chengeta chimiro chayo chekutsetseka kwenguva yakareba kupfuura simbi yakaenzana nayo. Kune bereing yemhepo, uko performance envelopu yese inoenderana nekuchengetedza mukaha wakafanana, unodzorwa, kugadzikana uku kwakakosha.
Kugadzikana kweThermal. Mukana wemhepo inotakura mhepo unowanikwa nepadiki diki—kazhinji 5–20 microns. Kuwedzera kwekupisa kwegwara rekutungamira kunochinja mukana uyu, zvichichinja mashandiro ebheyaringi uye zvichikonzera zvikanganiso zvekuisa miganhu. CTE yeGranite inenge hafu yesimbi uye chikamu chimwe muzvitatu chearuminiyamu. Izvi zvinoita kuti kururama kwekuisa miganhu ye nanometer kurambe kuri kwechokwadi mukati memaawa makumi maviri nemana ekushanda.
Kunyungudutsa uye Kudengenyeka. Granite ine simba rekudzivirira simbi zvakapetwa kagumi kupfuura simbi. Kana ikasanganiswa nekunyungudutsa kwefirimu remhepo, sisitimu iyi inogadzira "kunyungudutsa kaviri" iyo inoparadzanisa mitoro inonzwisisika kubva mukuzungunuka kwepasi uye ruzha rwemota. Izvi zvakakosha kune mashandisirwo akaita semakoramu emwenje yemagetsi nemainterferometer, uko kudengenyeka kunokanganisa kugadziriswa kwemufananidzo.
Hazvina Magneti, Hazvina Magneti. Munzvimbo dzekugadzira ma semiconductor uye zvemagetsi, kudzivirira masimba emagineti uye kufambisa magetsi pedyo nemaitiro anonzwa kazhinji chinhu chakaoma. Granite inozadzisa izvi pasina kumwe kurapwa.
Mhedzisiro ye "Kuderedza Mvura Kaviri"
Hechino chinoita kuti musanganiswa wegranite-air bearing ushande zvakanaka. Granite pachayo inopa damping inoshamisa—inoderedza kutaurirana kwemuchina nekusvika kagumi kana tichienzanisa nesimbi yakakandwa. Firimu remhepo rinopa damping yakawedzerwa ine viscous, ichigadzirisa kudedera kwemhepo. Pamwe chete, vanogadzira chinonzi mainjiniya "double-damping".
Izvi zvinoreva kuti danho rekuisa mhepo yegranite harisi rekungori rakarurama chete; rakanyarara. Danho racho rinofamba zvakanaka, pasina kuzununguka kudiki kunotambudza mabheyaringi emuchina. Rinogadzikana nekukurumidza, pasina kurira kunogona kunonotsa kuyerwa. Uye rinochengetedza kururama kwaro kwemakore ekushanda, pasina kupera zvishoma nezvishoma kunoderedza kushanda kwebheyaringi yemuchina.
Mabheyaringi emhepo eGranite anoshandiswa chaizvo
Rondedzero yekushandiswa inoita serwendo rwekuona makona akanyatsojeka ekugadzira nekuongorora kwemazuva ano:
Semiconductor Lithography uye Wafer Inspection. Kudzokororwa kwenzvimbo ye sub-nanometer kunodiwa kuti zvinhu zvienderane nemazvo pa wafer. Granite air bearingers inopa kufamba kusingakweshane, kusingabatanidzi kunoita kuti pave nekunyatsojeka kunodiwa pakugadzira chips dzechizvarwa chinotevera.
Michina yekuyera zvinhu (CMMs). Kusanganiswa kwemagiya egranite akakodzera uye mabheringi emhepo ndiyo nzira yakanakisisa yeCMMs, uko kutenderera kwechikamu kunoparadza kuyera. Kusavapo kwekukweshana uye kutsvedza kwebearing yemhepo kunogonesa kuisa nzvimbo mukuwedzera kwenanometer.
Masisitimu ekuyera anoshandiswa neOptical uye Laser. Chero sisitimu yekuyera inoshandisa interferometry kana optical imaging inoda danho rekufamba risingakonzere vibration kana positioning error. Mabearings emhepo egranite anopa kugadzikana kunodiwa kune aya maapplication anorema.
Kuongororwa kweMabhatiri eEV. Sezvo kugadzirwa kwemabhatiri emotokari yemagetsi kuri kuwedzera, kudiwa kwemasisitimu ekuongorora anomhanya zvakanyanya uye akanyatsojeka kwawedzera zvakanyanya. Matanho ekubata mhepo yegranite anopa kumhanya uye kururama kunodiwa pakuongorora saizi dzemaseru ebhatiri, kurongeka kwemaelectrode, nezvimwe zvinhu zvakakosha.
Kuboorera nekushandisa PCB. Kuboorera nePCB nekukurumidza kunoda nzvimbo nekukurumidza uye chaiyo uye nguva shoma yekugadzika. Mabheyaringi emhepo anogonesa kufamba nekukurumidza uye kugadzikana kunodiwa kuti kugadzirwa kwemagetsi kubudirire.
Chii Chinosiyanisa ZHHIMG®
Hazvisi zvese zvikamu zvegranite air bearing zvakagadzirwa zvakaenzana. Hunhu hwegranite, kunyatsorongeka kwepakurovera, uye hunyanzvi hwevashandi vehunyanzvi zvese zvinosarudza kana air bearing ichishanda nemazvo.
PaZHHIMG®, granite yedu nhema yeZHHIMG® ine huwandu hwe ≈3100 kg/m³—yakakwirira kupfuura granite nhema zhinji dzekuEurope neAmerica—zvichivimbisa kugadzikana kwepamusoro uye kusakara. Magrinder edu makuru, ane ruzivo rwemakore anopfuura makumi matatu ekushandisa maoko, anowana hurefu hwe nanometer hunodiwa pakushandisa air bearing. ...
Uye kuzvipira kwedu kune mhando—zvakapfupikiswa mumutemo wedu wemhando yepamusoro, "Bhizinesi rekugadzirisa zvinhu nemazvo harifanirwe kunge rakaoma zvakanyanya”—kunovimbisa kuti chikamu chega chega chegranite chinobuda panzvimbo yedu chinosangana nezvinodiwa zvakanyanya pasi rose.
Ungave uri kuvaka chizvarwa chinotevera chemidziyo ye semiconductor lithography, CMM ine magadzirirwo akanyanya, kana sisitimu yekuongorora mabhatiri eEV, musanganiswa we granite chaiyo uye tekinoroji yemhepo inopa hwaro hwekudzora kufamba kwe nanometer. Uye kuZHHIMG®, tave tichinyatsogona musanganiswa iwoyo kwemakumi emakore.
