Kodi granite yolimba kwambiri imasinthira bwanji malire a magwiridwe antchito amitundu ingapo yolondola kwambiri? Kusanthula mozama za ubwino wake waukulu.

M'magawo ang'onoang'ono monga kupanga semiconductor ndi kusonkhana kwa zida za kuwala, kufunafuna malo olondola a sub-micron kapena ngakhale nanometer-level-level ndi ma multi-axis precision worktables sikutha. Granite yolimba kwambiri (yokhala ndi kachulukidwe ≥3100kg/m³) ikukhala chinthu chofunikira kwambiri pakuwongolera magwiridwe antchito a mabenchi ogwirira ntchito chifukwa cha mawonekedwe ake apadera. Zotsatirazi ndikuwunika za ubwino wake wosasinthika kuchokera ku miyeso inayi yoyambira.
1. Kukhazikika kwapadera: "Chotchinga chachilengedwe" chopondereza kusokoneza kwa kugwedezeka
Pamene multi-axis worktable imayenda mothamanga kwambiri (ndi liwiro la mzere wopitilira 500mm / s) kapena kulumikizana ndi ma axis angapo, kugwedezeka kovutirako kumachitika. Tinthu tating'ono tating'ono tating'ono ta granite tokhala ndi kachulukidwe kakang'ono timalumikizana kwambiri, ndi ma frequency achilengedwe otsika ngati 10-20Hz, ndipo imatha kuyamwa kuposa 90% ya mphamvu yakunjenjemera yakunja. Mu semiconductor chip ma CD ma CD, imatha kuwongolera cholakwika chosuntha cha workbench mkati mwa ± 0.5μm, kupewa waya kapena kuwonongeka kwa chip chifukwa cha kugwedezeka. Poyerekeza ndi zida zachitsulo zotayidwa, kugwedezeka kwamphamvu kwa granite kumathamanga katatu, kumapangitsanso kusasinthika kwa kukonza.

2. Kukhazikika kwa kutentha: "Nangula wokhazikika" motsutsana ndi kusinthasintha kwa kutentha
M'malo okonzekera bwino, kusintha kwa kutentha kwa 0.1 ℃ kungayambitse kusintha kwa zinthu za 0.1μm/m. Coefficient of thermal expansion of high-density granite ndi (4-8) × 10⁻⁶/℃, yomwe ili pafupifupi 1/6 ya alloy aluminium. M'mikhalidwe yolondola kwambiri monga kugaya magalasi owoneka bwino, ngakhale kutentha kwa msonkhanowo kusinthasintha ndi ± 2 ℃, maziko a granite amathabe kusungitsa kulondola kwapang'onopang'ono kwa zigawo zazikulu za benchi, kuwonetsetsa kuti cholakwika cha lens curvature ndi chochepera 0.01D, kupitilira muyeso wamakampani.
3. Ultra-high rigidity: The "Solid Foundation Stone" yonyamula katundu wolemera
Ma multi-axis worktables nthawi zambiri amakhala ndi zida zolemetsa monga mitu ya laser ndi ma probe arrays (ndi katundu wa axis imodzi wopitilira 200kg). Mphamvu yoponderezedwa ya granite yolimba kwambiri ndi ≥200MPa, ndipo imatha kupirira katundu wofanana wopitilira 1000kg/m² popanda kupunduka kosatha. Bizinesi ina yazamlengalenga itatengera izi, pomwe tebulo lake lokhala ndi olamulira asanu litanyamula katundu wa 500kg, cholakwika cha Z-axis verticality chinangowonjezeka ndi 0.3μm, kuwonetsetsa kulondola kwa malo opindika ovuta.
4. Kukhalitsa kwa nthawi yaitali: Chepetsani ndalama zonse za moyo
Kuuma kwa Mohs kwa granite kumafika pa 6 mpaka 7, ndipo kukana kwake kuvala kumaposa kasanu kuposa chitsulo wamba. Mu mzere wopanga zinthu wa 3C womwe umagwira ntchito kwa maola pafupifupi 16 patsiku, maziko a granite amatha kukwaniritsa ntchito yopanda ntchito kwa zaka 8 mpaka 10, pomwe chitsulo chosungunula chikuwonetsa kuvala pamtunda wolumikizana ndi kalozera (kuya> 5μm) pambuyo pa zaka 3. Kuphatikiza apo, kusakhazikika kwake kwamankhwala kumathandizira kuti ikhalebe yolimba ya Ra≤0.2μm m'malo a acidic ndi alkaline, mosalekeza kupereka chiwongolero chokhazikika chazigawo zolondola monga olamulira a grating ndi ma mota amzere.
Kutsiliza: Granite wa High-density - "Wampikisano Wobisika" wa Precision Manufacturing
Kuchokera pa malo a nanoscale kupita ku ntchito yolemetsa kwambiri, granite yochuluka kwambiri ikukonzanso miyezo yaukadaulo ya ma multi-axis precision worktables ndi magwiridwe ake osayerekezeka. Kwa mabizinesi omwe amatsata kulondola komanso kudalirika kopitilira muyeso, kusankha maziko a granite apamwamba kwambiri (monga zinthu za ZHHIMG® zotsimikiziridwa ndi machitidwe atatu a ISO) sikungotsimikizira kupanga kwamakono komanso kuyika ndalama mwanzeru pakukweza njira zamtsogolo.
