Zigawo Zopangira Zapamwamba za Granite — Ma Castings Apadera a Granite a Zipangizo Zolondola Kwambiri

Si granite yonse yoyenera kugwiritsidwa ntchito m'mapangidwe olondola. Granite yomwe imagwiritsidwa ntchito m'zigawo zolondola kwambiri ndi granite wakuda wosankhidwa mwapadera wokhala ndi mchere wambiri - nthawi zambiri pafupifupi 3,100 kg/m³ - yomwe imapereka:

Kukhazikika kwa miyeso yonse kutentha: Kuchuluka kwa kutentha kwa granite wakuda wabwino ndi pafupifupi 5 × 10⁻⁶/°C, kutanthauza kuti gawo la mita imodzi limasintha kutalika ndi ma micrometer 5 okha pa digiri Celsius. Yerekezerani izi ndi aluminiyamu pa 23 × 10⁻⁶/°C kapena chitsulo pa 12 × 10⁻⁶/°C — granite ndi yolimba kwambiri kuposa chitsulo ndipo imakhala yolimba kwambiri kuposa aluminiyamu.

Kuchepetsa kugwedezeka kwapamwamba: Granite imachotsa mphamvu yogwedezeka bwino kwambiri kuposa chitsulo kapena aluminiyamu. Izi ndizofunikira kwambiri pazida zomwe zimachita miyeso kapena njira zomwe zimafuna nthawi yayitali yolumikizira - kuyang'anira maso, kuyeza kwa probe yosanthula, kapena makina aliwonse omwe chithunzi kapena kuwonekera bwino kwa chizindikiro ndikofunikira.

Palibe chiopsezo cha dzimbiri: Mosiyana ndi chitsulo chopangidwa ndi chitsulo, chomwe chimafuna zokutira zoteteza kuti zisachite dzimbiri, granite siigonjetsedwa ndi chinyezi cha mlengalenga ndi mankhwala ambiri a mafakitale. Palibe zokutira zoti ziwonongeke, palibe dzimbiri loti ziyeretsedwe, palibe kusintha kwa mawonekedwe komwe kumachitika chifukwa cha dzimbiri kwa zaka zambiri.

Makhalidwe a zinthu zofanana: Kapangidwe ka mchere wa granite wakuda wabwino ndi wofanana — palibe malire a tirigu, kulekanitsa, kapena kupsinjika kwamkati komwe kungayambitse kusintha kosayembekezereka kwa mawonekedwe. Gawo la granite limachita zinthu modziwikiratu chifukwa mawonekedwe ake ndi ofanana.

Kukana kuvala: Granite ndi yolimba kuposa zitsulo zambiri, zomwe zikutanthauza kuti mawonekedwe oyika, malo owonetsera, ndi njira zoyendetsera mabenchi zimasunga mawonekedwe awo kwa nthawi yayitali popanda kuvala koyezera.

Ogulitsa ena amalowetsa granite kapena marble yotsika mtengo kuti achepetse ndalama. Marble ili ndi kuchuluka kochepa kwambiri (nthawi zambiri 2,500–2,700 kg/m³), kutentha kwambiri, ndipo siisunga mawonekedwe olondola pakapita nthawi. ZHHIMG imagwiritsa ntchito granite wakuda wotsimikizika wokha - timapereka chitsimikizo chotsimikizira kuchuluka ndi kapangidwe kake ngati tipempha.

Kuponyera Mwapadera kwa Granite: Kuchokera pa Kapangidwe mpaka Gawo Lomalizidwa

Kupanga zigawo zolondola za granite ndi njira yopangira zinthu zosiyanasiyana zomwe zimaphatikiza mfundo zogwiritsira ntchito popanga zitsulo ndi kupanga miyala molondola:

Kusankha ndi kukonza zinthu: Mabuloko a granite osaphika amawunikidwa kuti awone ngati ali ndi mabala amkati, ngati ali ndi mchere wofanana, komanso ngati ali ndi kuchulukana. Zinthu zokhazo zomwe zimakwaniritsa zomwe timafunikira (>3,000 kg/m³) ndi zomwe zimapangidwa.

Kupanga mopanda dongosolo: Chipilala cha granite chimapangidwa kuti chikhale ndi mawonekedwe ofanana ndi kukula komaliza pogwiritsa ntchito kudula kokhala ndi nsonga ya diamondi komanso zida zopukutira mopanda dongosolo. Pa siteji iyi, kuchotsa zinthu kumakhala koopsa - nthawi zambiri kumachotsa 5-20 mm pa ntchito iliyonse.

Kupera kolondola: Makina opera a CNC okhala ndi mawilo a diamondi kapena CBN amapangitsa kuti gawoli likhale lokwanira. Pazigawo zazikulu, makina opera apadera okhala ndi mawonekedwe akuluakulu amasunga kupirira kosalala kuposa 1 μm/m pamalo onse ogwirira ntchito.

Kumaliza Mbali: Mapulatifomu okwezeka, m'mphepete mwa datum, mawonekedwe a mabowo, ndi malo okwerera amalandira ntchito zina zolondola - nthawi zambiri zomalizidwa ndi amisiri okhala ndi zaka zambiri - kuti akwaniritse kulekerera koyenera komwe kumafunikira pazinthu zogwirira ntchito.

Kutsimikizira Ubwino: Gawo lililonse lofunikira limayesedwa pogwiritsa ntchito makina oyezera ogwirizana, ma interferometer a laser, kapena ma level amagetsi okhala ndi resolution ya sub-micron. Zipangizo zonse zoyezera zimayesedwa motsatira miyezo ya dziko lonse ya metrology.
