Maziko a Ultra-Precision: Kuyenda ndi Ma Air Bearings, Linear Motors, ndi Granite Integration

Munthawi yomwe zinthu zamakono zimapangidwira, "kulondola" ndi cholinga chachikulu. Pamene makampani opanga zinthu zamagetsi, ndege, ndi zida zamankhwala akukankhira ku mfundo zazing'ono komanso kulekerera kolimba, maziko a makina athu akuganiziridwanso. Kwa mainjiniya ndi ophatikiza makina, mkangano nthawi zambiri umayang'ana kwambiri pa kakonzedwe kabwino ka makina oyendera: Kodi tingatani kuti tikwaniritse kuyenda kopanda kukangana popanda kuwononga kulimba kwa kapangidwe kake?

Yankho lake lili mu mgwirizano pakati pa Air Bearings, Linear Motors, ndiZigawo Zolondola Kwambiri—zonsezi zikuthandizidwa ndi kukhazikika kosayerekezeka kwa granite yachilengedwe. Ku ZHHIMG, tawona kusintha kwakukulu m'misika ya ku Europe ndi America pankhani ya njira zolumikizirana za granite-air bearing. Nkhaniyi ikufotokoza zaukadaulo waukadaulo uwu ndi momwe amagwiritsidwira ntchito m'dziko lenileni.

Kunyamula Mpweya vs. Linear Motor: Ubale Wogwirizana

Pokambirana za “Air Bearing vs. Linear Motor,” ndi kulakwitsa kofala kuwaona ngati ukadaulo wopikisana. Pa gawo lolondola kwambiri, amachita ntchito ziwiri zosiyana koma zogwirizana.

Ma Air Bearings amapereka chitsogozo. Pogwiritsa ntchito mpweya wochepa wopanikizika—nthawi zambiri kuyambira ma microns 5 mpaka 10—amachotsa kukhudzana kwa thupi pakati pa ngolo yoyenda ndi pamwamba pa chitsogozo. Izi zimapangitsa kuti pasakhale kukangana kosasinthasintha (stiction) komanso "kusalala" komwe kumachotsa kusakhazikika kwa pamwamba.

Koma Linear Motors, imapereka mphamvu yoyendetsera. Mwa kusintha mphamvu zamagetsi kukhala zoyenda molunjika kudzera m'maginito, zimachotsa kufunikira kwa zinthu zotumizira zamagetsi monga zomangira za lead kapena malamba. Izi zimachotsa backlash ndi hysteresis kuchokera mu equation.

Zikaphatikizidwa ziwirizi, zotsatira zake zimakhala "Gawo Losakhudzana." Chifukwa chakuti kuyendetsa kapena chitsogozo sichimakhudza kukangana, dongosololi limatha kupeza kukana kopanda malire komanso kubwerezabwereza kwangwiro. Komabe, dongosolo lotereli limakhala lolondola ngati pamwamba pake, zomwe zimatitsogolera ku kufunika kwa granite.

Udindo Wofunika Kwambiri wa Zigawo Zolondola

Gawo lolondola si kungopanga mota ndi chogwirira; ndi gulu lovuta laZigawo Zolondola Kwambirizomwe ziyenera kugwira ntchito mogwirizana. Mu ntchito zolondola kwambiri, kusankha zinthu zomwe zili muzinthu izi ndiye chinthu chofunikira kwambiri pakugwira ntchito kwa nthawi yayitali.

Zipangizo zakale monga aluminiyamu kapena chitsulo zimatha kukulitsa kutentha komanso kuchepetsa kupsinjika kwamkati, zomwe zingayambitse kupindika pakapita nthawi. Magawo ogwira ntchito bwino tsopano amagwiritsa ntchito ulusi wa ceramic kapena carbon wapadera posuntha zinthu kuti achepetse kulemera, koma zigawo "zosasunthika" - maziko ndi zitsogozo - zimadalira kwambiri granite ya grade metrology.

Kukhazikika kwa kapangidwe ka zinthuzi kumatsimikizira kuti pamene mota yolunjika ikuthamanga kwambiri, mphamvu zoyankhira sizimayambitsa "kulira" kapena kugwedezeka komwe kungasokoneze filimu yopyapyala ya bearing ya mpweya. Kukhazikika kumeneku ndikofunikira kwambiri kuti kukhalebe kutalika kwa kuuluka kwa sub-micron komwe kumafunikira kuti kugwire ntchito bwino.

Chifukwa Chake Granite Air Bearings Ndi Muyezo Wa Makampani

Mawu akuti Granite Air Bearings amatanthauza kuphatikiza ukadaulo wa mpweya wonyamula mpweya mwachindunji pa chitsogozo cha granite cholumikizidwa bwino. Kuphatikiza kumeneku kwakhala muyezo wagolide pazifukwa zingapo zaukadaulo:

1. Kusalala Kwambiri: Ma bearing a mpweya amafuna malo osalala kwambiri kuti filimu ya mpweya isagwe. Granite ikhoza kulumikizidwa pamanja kuti ikhale yolimba kuposa pamwamba pa chitsulo chilichonse chopangidwa ndi makina, zomwe zimapangitsa kuti ikhale "njira" yabwino kwambiri.

2. Kuchepetsa Kugwedezeka: Granite ili ndi chiŵerengero chapamwamba cha kuzizira kwachilengedwe. Mu dongosolo loyendetsedwa ndi mota yamphamvu kwambiri, granite imayamwa mphamvu yamagetsi apamwamba yomwe ingayambitse "phokoso" mu deta yoyezera.

3. Kusalowererapo kwa Mankhwala ndi Maginito: Mosiyana ndi chitsulo chopangidwa ndi chitsulo, granite siidzazizira kapena kukhala ndi maginito. Pa ntchito za semiconductor komwe kusokonezedwa ndi maginito kungawononge wafer, kapena m'zipinda zoyera zonyowa komwe dzimbiri ndi chiopsezo, granite ndiye chisankho chokhacho choyenera.

Kugwiritsa Ntchito Mwanzeru: Kuchokera ku Semiconductors mpaka ku Metrology

ZothandizaKugwiritsa Ntchito Mabearings a Granite Airakukulirakulira pamene mafakitale akupita patsogolo pakuwunika zinthu zokha komanso nanometer-scale.

• Kujambula ndi Kuyang'anira kwa Semiconductor: Pakupanga ma microchip, siteji iyenera kusuntha wafer pansi pa mzere wowala bwino ndi nanometer molondola. Kugwedezeka kulikonse komwe kumachitika chifukwa cha kukangana kungasokoneze chithunzicho. Magawo okhala ndi mpweya wa granite amapereka malo "opanda phokoso" ofunikira pazinthu izi.

• Kukonza Ma Micro-Machining a Laser: Mukadula mapangidwe ovuta mu ma stenti azachipatala kapena zowonetsera, liwiro losasinthika lomwe limaperekedwa ndi ma linear motors ndi ma air bearing limatsimikizira mtundu wosalala wa m'mphepete womwe ma mechanical bearing sangafanane nawo.

• Kuyeza kwa Mawonekedwe: Ma CMM apamwamba (Makina Oyezera Magawo Ogwirizana) amagwiritsa ntchito ma granite air bearing kuti atsimikizire kuti kuyenda kwa probe kwapatukana kwathunthu ndi kugwedezeka kwa pansi, zomwe zimapangitsa kuti zitsimikizidwe kuti zigawo zili ndi kulondola kwa micron.

Ubwino wa ZHHIMG mu Uinjiniya Wolondola

Ku ZHHIMG, tikumvetsa kuti kusintha kwa kayendetsedwe ka zinthu kosakhudzana ndi kusuntha kumatanthauza ndalama zambiri pa khalidwe. Ukadaulo wathu uli mu kukonza ndi kulumikiza bwino ma granite omwe amapangitsa kuti magawo apamwamba awa akhale otheka. Mwa kupeza granite wakuda wochuluka kwambiri komanso kugwiritsa ntchito interferometry yapamwamba kuti titsimikizire pamwamba, timaonetsetsa kuti chilichonseGawo Lolondola KwambiriTimapanga zinthu zomwe zimakwaniritsa zofunikira kwambiri pamsika wapadziko lonse wa metrology.

Kusintha kwa kayendetsedwe ka kayendetsedwe ka zinthu kukuchoka pa “kuphwanyika ndi kutha” kwa zinthu zakale kupita ku “kuyandama ndi kuyendetsa” kwa mtsogolo. Pamene tikupitiriza kukonza kuphatikiza kwa Granite Air Bearings ndi Linear Motors, ZHHIMG ikudziperekabe kupereka maziko omwe ukadaulo wotsatira udzamangidwirepo.
