Kodi granite yochuluka kwambiri imakonzanso bwanji malire a magwiridwe antchito a matebulo ogwirira ntchito olondola a multi-axis? Kusanthula mozama kwa ubwino wake waukulu.

M'magawo amakono monga kupanga ma semiconductor ndi kusonkhana kwa zida zamagetsi, kufunafuna kulondola kwa malo a sub-micron kapena nanometer pogwiritsa ntchito matebulo ogwirira ntchito olondola a multi-axis sikutha. Granite yolemera kwambiri (yokhala ndi kuchuluka kwa ≥3100kg/m³) ikukhala chinthu chofunikira kwambiri pakukonza magwiridwe antchito a mabenchi ogwirira ntchito chifukwa cha mawonekedwe ake apadera. Zotsatirazi ndi kusanthula kwa ubwino wake wosasinthika kuchokera ku miyeso inayi yayikulu.
1. Kukhazikika kwapadera: "Chotchinga chachilengedwe" choletsa kusokonezeka kwa kugwedezeka
Pamene tebulo logwirira ntchito la multi-axis likuyenda mofulumira kwambiri (ndi liwiro lolunjika lopitirira 500mm/s) kapena mu kulumikizana kwa multi-axis, kugwedezeka kovuta kumachitika. Tinthu ta mchere tamkati mwa granite yapamwamba kwambiri timakhala tolumikizana kwambiri, ndi ma frequency achilengedwe otsika ngati 10-20Hz, ndipo timatha kuyamwa mphamvu yoposa 90% ya kugwedezeka kwakunja. Mu njira yopangira ma chip a semiconductor, imatha kuwongolera cholakwika cha kusamuka kwa benchi logwirira ntchito mkati mwa ± 0.5μm, kupewa kuwonongeka kwa waya kapena chip komwe kumachitika chifukwa cha kugwedezeka. Poyerekeza ndi zipangizo zachikhalidwe zachitsulo chopangidwa ndi chitsulo, kugwedezeka kwa granite kumakhala kofulumira katatu, zomwe zimapangitsa kuti ntchitoyo ikhale yogwirizana kwambiri.

2. Kukhazikika kwa kutentha: "Nangula Wokhazikika" motsutsana ndi kusinthasintha kwa kutentha
Mu malo okonzedwa bwino, kusintha kwa kutentha kwa 0.1℃ kungayambitse kusintha kwa zinthu kwa 0.1μm/m. Kuchuluka kwa kutentha kwa granite yokhala ndi kuchuluka kwakukulu ndi (4-8) × 10⁻⁶/℃ kokha, komwe kuli pafupifupi 1/6 ya aloyi ya aluminiyamu. Muzochitika zolondola kwambiri monga kupukuta kwa lenzi ya optical, ngakhale kutentha kwa workshop kusinthasintha ndi ±2℃, maziko a granite amathabe kusunga kulondola kwa malo a micron a zigawo zazikulu za workbench, kuonetsetsa kuti cholakwika cha curvature ya lenzi ndi chochepera 0.01D, choposa kwambiri muyezo wamakampani.
3. Kulimba kwambiri: "Mwala Wolimba Woyambira" wonyamulira katundu wolemera
Matebulo ogwirira ntchito okhala ndi ma axis ambiri nthawi zambiri amakhala ndi zinthu zolemera monga mitu ya laser ndi ma probe arrays (okhala ndi katundu wa single-axis woposa 200kg). Mphamvu yokakamiza ya granite yokhala ndi kuchuluka kwakukulu ndi ≥200MPa, ndipo imatha kupirira katundu wofanana woposa 1000kg/m² popanda kusintha kosatha. Kampani ina ya ndege itagwiritsa ntchito izi, pamene tebulo lake logwirira ntchito la ma axis asanu linali ndi katundu wokonza wa 500kg, cholakwika cha Z-axis verticality chinawonjezeka ndi 0.3μm, zomwe zimatsimikizira bwino kulondola kwa kukonza kwa malo ovuta opindika.
4. Kukhalitsa kwanthawi yayitali: Chepetsani mtengo wonse wa moyo
Kulimba kwa granite kwa Mohs kumafika pa 6 mpaka 7, ndipo kukana kwake kutopa kumaposa kasanu kuposa chitsulo wamba. Mu mzere wopanga zinthu wa 3C womwe umagwira ntchito kwa maola 16 patsiku, maziko a granite amatha kugwira ntchito popanda kukonza kwa zaka 8 mpaka 10, pomwe maziko achitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo amawonetsa kuwonongeka pamwamba pa njanji yotsogolera (kuya > 5μm) patatha zaka 3. Kuphatikiza apo, kusakhala ndi mphamvu kwa mankhwala kumathandizira kuti isunge kuuma kwa pamwamba kwa Ra≤0.2μm m'malo okhala ndi asidi ndi alkaline, zomwe zimapangitsa kuti pakhale kukhazikika kwa kukhazikitsa kwa zigawo zolondola monga ma grating rulers ndi ma linear motors.
Mapeto: Granite Yokhala ndi Density Yaikulu - "Wodziwika Bwino Kwambiri" wa Precision Manufacturing
Kuchokera pa malo ogwirira ntchito a nanoscale mpaka kukonza zinthu molemera, granite yolemera kwambiri ikusintha miyezo yaukadaulo ya ma multi-axis precision worktables ndi magwiridwe ake osayerekezeka. Kwa makampani omwe amatsata kulondola ndi kudalirika, kusankha maziko apamwamba a granite (monga zinthu za ZHHIMG® zotsimikiziridwa ndi machitidwe atatu a ISO) sikuti ndi chitsimikizo cha kupanga kwamakono kokha komanso ndalama zoyendetsera bwino pakukonzanso njira zamtsogolo.
