Ultra-precision motion module: Kusanthula mozama kwa maziko olondola a granite ndi maziko opangira mchere.

Kusankhidwa kwa zinthu zoyambira kumakhala ndi gawo lofunika kwambiri popanga ma ultra-precision motion modules. Maziko olondola a granite ndi maziko opangira mchere, monga zosankha ziwiri zazikulu, chilichonse chili ndi mikhalidwe yosiyana yomwe imasiyana kwambiri ndi kukhazikika, kusungidwa kolondola, kulimba, ndi mtengo.

Kukhazikika: Kuchulukana kwachilengedwe motsutsana ndi zopangapanga
Pambuyo pa zaka mamiliyoni ambiri za kusintha kwa geological, granite imapanga mawonekedwe owundana kwambiri komanso ofanana kudzera mu mgwirizano wachilengedwe wa quartz, feldspar, ndi mchere wina. M'madera akumafakitale komwe zida zazikulu zimapanga kugwedezeka kwamphamvu, kapangidwe ka makristalo a granite amachepetsera kusokonezeka kumeneku, kumachepetsa matalikidwe a kugwedezeka komwe kumatumizidwa ku ma module oyenda bwino kwambiri ndi 80%. Izi zimawonetsetsa kuti zimagwira ntchito bwino panthawi yokonza kapena kuyang'anira ntchito zolondola kwambiri, monga kuyika bwino kwa tchipisi tamagetsi mumayendedwe a photolithography.

Maziko opangira mchere amapangidwa kuchokera ku tinthu tating'ono ta mchere tosakanikirana ndi zomangira zapadera, zomwe zimapangitsa kuti pakhale mawonekedwe amkati omwe ali ndi zinthu zabwino zogwedera. Ngakhale kuti amapereka chitetezo chothandizira kugwedezeka kwachinthu chilichonse ndikupanga malo okhazikika ogwirira ntchito a ma modules oyandama kwambiri oyendetsa mpweya, machitidwe awo pansi pa mphamvu yamphamvu, kugwedezeka kosalekeza kumakhala kotsika pang'ono poyerekeza ndi maziko a granite. Izi zitha kuyambitsa zolakwika zazing'ono pamapulogalamu olondola kwambiri.

Kusunga Molondola: Kukula kochepa kwachilengedwe motsutsana ndi kutsika kolamulidwa
Granite imadziwika chifukwa chochepa kwambiri pakukulitsa kutentha (nthawi zambiri 5–7 × 10⁻⁶/°C). Ngakhale m'malo okhala ndi kusinthasintha kwakukulu kwa kutentha, maziko olondola a granite amawonetsa kusintha kochepa kwambiri. Mwachitsanzo, pakugwiritsa ntchito zakuthambo, ma module a granite-air-floating ultra-precision motion modules amawonetsetsa kuti magalasi a submicron-level awonetsetse kuti ma telescopes ali olondola, zomwe zimathandiza akatswiri a zakuthambo kuti azijambula tsatanetsatane wa zakuthambo zakutali.

Zida zopangira mchere zimatha kupangidwa kuti ziwongolere ndikuwongolera mawonekedwe akukula kwamafuta, kukwaniritsa ma coefficients ofanana kapena otsika kuposa a granite. Izi zimawapangitsa kukhala oyenera pazida zoyezera kwambiri zoyezera kutentha kwambiri. Komabe, kukhazikika kwanthawi yayitali kwa kulondola kwawo kumakhalabe kotsimikizika chifukwa cha zinthu monga kukalamba kwa binder, zomwe zingayambitse kuchepa kwa magwiridwe antchito pakanthawi yayitali.

Kukhalitsa: Kulimba kwambiri kwa mwala wachilengedwe motsutsana ndi ma composites osatopa
Kulimba kwa granite (mulingo wa Mohs: 6-7) kumapereka kukana kovala bwino. M'ma laboratories a sayansi ya zida, zoyambira za granite zamamodule zoyandama zomwe zimagwiritsidwa ntchito pafupipafupi ndi mpweya zimakana kukangana kwanthawi yayitali kuchokera ku zotsetsereka, kukulitsa kukonzanso kopitilira 50% poyerekeza ndi zoyambira wamba. Ngakhale mwayi uwu, brittleness ya granite imabweretsa chiopsezo chothyoka mwangozi.

Maziko oponyera mchere amawonetsa zinthu zabwino kwambiri zothana ndi kutopa, kusunga umphumphu pakapita nthawi yayitali yobwerezabwereza ya ma module apamwamba kwambiri oyandama mpweya. Kuphatikiza apo, amawonetsa kukana kwa dzimbiri kwa mankhwala, kumapangitsa kulimba m'malo owononga pang'ono. Komabe, m'malo ovuta kwambiri monga chinyezi chambiri, chomangira mkati mwa zoyikapo mchere zitha kutsika, ndikusokoneza kulimba kwake konse.

Mtengo Wopanga ndi Kuvuta Kwambiri**: Zovuta zakuchotsa miyala yachilengedwe motsutsana ndi njira zoponya mwachinyengo
Migodi ya granite ndi mayendedwe amaphatikiza zinthu zovuta, pomwe kukonza kwake kumafuna zida ndi njira zapamwamba. Chifukwa cha kuuma kwake kwakukulu ndi kuphulika kwake, ntchito monga kudula, kugaya, ndi kupukuta nthawi zambiri kumabweretsa mitengo yamtengo wapatali, yomwe imayendetsa ndalama zopangira.

Mosiyana ndi izi, kupanga maziko opangira mchere kumafuna nkhungu ndi njira zinazake. Ngakhale kukula kwa nkhungu koyambirira kumawononga ndalama zambiri, kupangidwa kochuluka kotsatira kumakhala kopindulitsa pachuma chikangokhazikitsidwa.
