Ngakhale nsanja ya granite ingawoneke ngati mwala wosavuta, zosankha zimasintha kwambiri pochoka ku ntchito wamba zamafakitale kupita kukuyang'ana kwapamwamba kwambiri ndi metrology. Kwa ZHHIMG®, kupereka zigawo zolondola kwa atsogoleri a dziko mu semiconductor ndi laser teknoloji kumatanthauza kuzindikira kuti nsanja yoyezera kuwala sikungokhala maziko-ndi gawo lofunikira, losasinthika la optical system palokha.
Zofunikira pakuwunika kwa kuwala - zomwe zimaphatikizapo kujambula kwapamwamba kwambiri, kusanthula kwa laser, ndi interferometry - zimatanthauzidwa ndi kufunikira kochotsa magwero onse a phokoso la muyeso. Izi zimatsogolera ku kuyang'ana pa zinthu zitatu zapadera zomwe zimasiyanitsa nsanja yeniyeni ya kuwala kuchokera ku mafakitale ovomerezeka.
1. Kachulukidwe Wapamwamba Wakugwedezeka Kwakugwedezeka Kosagwirizana
Pazitsulo zokhazikika za CNC zamakampani, chitsulo choponyedwa kapena granite wamba chingapereke kuuma kokwanira. Komabe, makina opangira kuwala amakhudzidwa kwambiri ndi kusamuka kwa mphindi zochepa komwe kumachitika chifukwa cha kugwedezeka kwakunja kuchokera ku zida za fakitale, makina oyendetsera mpweya, ngakhale magalimoto akutali.
Apa ndi pamene sayansi yakuthupi imakhala yofunika kwambiri. Pulatifomu yowoneka bwino imafuna granite yokhala ndi kunyowa kwapadera kwachilengedwe. ZHHIMG® imagwiritsa ntchito eni ake a ZHHIMG® Black Granite (≈ 3100 kg/m³). Zinthu zowoneka bwino kwambirizi, mosiyana ndi ma granite otsika kapena zolowa m'malo mwa nsangalabwi, zimakhala ndi mawonekedwe a crystalline omwe amatha kuwononga mphamvu zamakina. Cholinga sikungochepetsa kugwedezeka, koma kuwonetsetsa kuti mazikowo amakhalabe opanda phokoso, kuchepetsa kusuntha kwapakati pakati pa lens yowunikira ndi chitsanzo choyang'aniridwa pamlingo wa micron.
2. Kukhazikika Kwambiri Kutentha Kwambiri Kulimbana ndi Drift
Standard mafakitale nsanja kulekerera kusintha pang'ono dimensional; gawo lakhumi la digiri Celsius silingakhale lofunikira pakubowola. Koma m'makina owoneka bwino omwe amayesa molondola kwa nthawi yayitali, kutentha kulikonse mu geometry yoyambira kumabweretsa zolakwika mwadongosolo.
Kuti muwonetsetse kuwala, nsanja iyenera kukhala ngati sinki yotentha yokhala ndi coefficient yotsika kwambiri ya kufalikira kwamafuta (CTE). Kulemera kwapamwamba ndi kachulukidwe ka ZHHIMG® Black Granite kumapereka inertia yofunikira yotenthetsera kukana kufalikira kwa mphindi ndi kutsika komwe kungachitike mkati mwa chipinda cholamulidwa ndi nyengo. Kukhazikika kumeneku kumatsimikizira kuti mtunda wolunjika wokhazikika komanso kulinganiza kwa mapulaneti a zigawo za kuwala kumakhalabe kosasunthika, kutsimikizira kukhulupirika kwa miyeso yomwe imatenga maola ambiri-chinthu chosakambitsirana pakuwunika kwapamwamba kwambiri kapena mawonekedwe amtundu wa flat-panel.
3. Kukwaniritsa Nano-Level Flatness ndi Geometric Precision
Kusiyana kowonekera kwambiri ndikofunika kwa flatness. Ngakhale maziko a mafakitale wamba amatha kukumana ndi Grade 1 kapena Grade 0 flatness (yoyezedwa mu ma microns ochepa), makina owonera amafunikira kulondola kwamtundu wa nanometer. Mulingo uwu wa ungwiro wa geometric ndi wofunikira kuti upereke ndege yodalirika yolozera magawo amzere ndi machitidwe a autofocus omwe amagwira ntchito pa mfundo zosokoneza kuwala.
Kukwaniritsa ndikutsimikizira kutsika kwa nanometer kumafuna njira yosiyana yopangira. Zimaphatikizapo njira zapadera zogwiritsira ntchito makina apamwamba kwambiri monga Taiwan Nanter grinders ndipo zimatsimikiziridwa ndi zipangizo zamakono za metrology monga Renishaw Laser Interferometers. Izi ziyenera kuchitika pamalo okhazikika kwambiri, monga ma workshop a ZHHIMG® a vibration-damped, oyendetsedwa ndi nyengo, komwe ngakhale kuyenda kosawoneka bwino kwa mpweya kumachepetsedwa.
M'malo mwake, kusankha nsanja yolondola ya granite kuti muwunikenso ndi lingaliro loyika ndalama mu gawo lomwe limatsimikizira kulondola kwa kuyeza kwa kuwala komweko. Pamafunika kuyanjana ndi wopanga yemwe amawona satifiketi ya ISO 9001 ndi kutsata kwatsatanetsatane kwazithunzi osati ngati mawonekedwe osasankha, koma ngati zofunika zoyambira kulowa mdziko la Ultra-precision Optics.
