Ngakhale nsanja ya granite ingawoneke ngati mwala wamba, njira zosankhira zimasintha kwambiri posintha kuchoka pa ntchito wamba zamafakitale kupita ku kuyang'anira kuwala ndi metrology yofunikira kwambiri. Kwa ZHHIMG®, kupereka zigawo zolondola kwa atsogoleri apadziko lonse muukadaulo wa semiconductor ndi laser kumatanthauza kuzindikira kuti nsanja yoyezera kuwala si maziko okha - ndi gawo lofunikira, losakambirana la makina owonera okha.
Zofunikira pakuwunika kwa maso—zomwe zimaphatikizapo kujambula zithunzi zokulitsa kwambiri, kusanthula kwa laser, ndi interferometry—zimatanthauzidwa ndi kufunika kochotsa magwero onse a phokoso loyezera. Izi zimabweretsa kuyang'ana kwambiri pazinthu zitatu zapadera zomwe zimasiyanitsa nsanja yeniyeni ya maso ndi ya mafakitale wamba.
1. Kuchuluka Kwambiri kwa Kuchepetsa Kugwedezeka Kosayerekezeka
Pa maziko a CNC a mafakitale wamba, chitsulo chopangidwa ndi chitsulo kapena granite wamba angapereke kuuma kokwanira. Komabe, makonzedwe a kuwala ndi ofunikira kwambiri kusuntha kwaching'ono komwe kumachitika chifukwa cha kugwedezeka kwakunja kuchokera ku zida za fakitale, makina oyendetsera mpweya, kapena magalimoto akutali.
Apa ndi pomwe sayansi ya zinthu zakuthupi imakhala yofunika kwambiri. Pulatifomu yowunikira imafuna granite yokhala ndi kupopera kwapadera kwa zinthu. ZHHIMG® imagwiritsa ntchito ZHHIMG® Black Granite yake (≈ 3100 kg/m³). Chipangizochi chokhala ndi kuchuluka kwakukulu, mosiyana ndi granite yotsika kapena malo olowa m'malo mwa marble, chili ndi kapangidwe ka kristalo kogwira mtima kwambiri potulutsa mphamvu ya makina. Cholinga chake sikuti kungochepetsa kugwedezeka, komanso kuonetsetsa kuti maziko ake amakhala chete, kuchepetsa kuyenda pakati pa lenzi yolunjika ndi chitsanzo chowunikidwa pamlingo wa sub-micron.
2. Kukhazikika Kwambiri kwa Kutentha Polimbana ndi Kugwedezeka
Mapulatifomu wamba a mafakitale amalekerera kusintha pang'ono kwa kukula; gawo limodzi mwa magawo khumi a digiri Celsius silingakhale lofunika pakubowola. Koma m'makina owonera omwe amachita miyeso yolondola kwa nthawi yayitali, kusuntha kulikonse kwa kutentha mu geometry ya maziko kumabweretsa cholakwika chadongosolo.
Pakuwunika kwa kuwala, nsanja iyenera kugwira ntchito ngati sinki yotenthetsera yokhala ndi coefficient yotsika kwambiri ya expansion ya kutentha (CTE). Kulemera kwakukulu ndi kuchuluka kwa ZHHIMG® Black Granite kumapereka kutentha kofunikira kuti kupewe kukulitsa ndi kusinthasintha kwa mphindi zomwe zingachitike mchipinda cholamulidwa ndi nyengo. Kukhazikika kumeneku kumatsimikizira kuti mtunda wolunjika bwino komanso kulinganiza bwino kwa zigawo za kuwala kumakhalabe kokhazikika, kutsimikizira umphumphu wa miyeso yomwe imapitilira maola ambiri—chinthu chosakambidwa pakuwunika kwa wafer wapamwamba kwambiri kapena metrology yowonetsera ya flat-panel.
3. Kukwaniritsa Kusalala ndi Kulondola kwa Geometric pa Nano-Level
Kusiyana koonekera kwambiri ndi kufunika kwa kusalala. Ngakhale kuti maziko wamba a mafakitale amatha kukwaniritsa kusalala kwa Giredi 1 kapena Giredi 0 (komwe kumayesedwa mu ma microns ochepa), machitidwe a kuwala amafuna kulondola mu nanometer range. Mlingo uwu wa ungwiro wa geometric ndi wofunikira kuti pakhale malo odalirika owunikira magawo a mzere ndi machitidwe a autofocus omwe amagwira ntchito motsatira mfundo za kusokoneza kuwala.
Kukwaniritsa ndi kutsimikizira kusalala kwa nanometer kumafuna njira yosiyana kwambiri yopangira. Zimaphatikizapo njira zapadera kwambiri pogwiritsa ntchito makina apamwamba monga Taiwan Nanter grinders ndipo zimatsimikiziridwa ndi zida zapamwamba kwambiri zoyezera zinthu monga Renishaw Laser Interferometers. Njirayi iyenera kuchitika pamalo okhazikika kwambiri, monga ma workshop a ZHHIMG® omwe amaletsa kugwedezeka, komanso olamulidwa ndi nyengo, komwe ngakhale mayendedwe ampweya ocheperako amachepetsedwa.
Mwachidule, kusankha nsanja yolondola ya granite kuti muyang'anire kuwala ndi chisankho chofuna kuyika ndalama mu gawo lomwe limatsimikizira kulondola kwa muyeso wowona. Zimafunika kugwirizana ndi wopanga yemwe amawona satifiketi ya ISO 9001 ndi kutsata kwathunthu osati ngati zinthu zomwe mungasankhe, koma ngati zofunikira zoyambira kuti mulowe m'dziko la ma optics olondola kwambiri.
