Nyob rau hauv pem hauv ntej ntawm nanotechnology, semiconductor lithography, thiab tom ntej no -tiam wafer tshuaj xyuas, cov npoo ntawm qhov yuam kev tau ploj mus. Peb tsis tham txog microns lawm; peb tab tom ua haujlwm hauv thaj tsam ntawm nanometers thiab sub-nanometers. Nyob rau hauv lub npe no, ib txwm siv tshuab kev taw qhia tshuab- pob screws, linear guides, thiab dov lub ntsiab bearings- tsoo lub cev phab ntsa. Kev sib txhuam, lo- qhov tshwm sim plam, thiab cov khoom tsim tshwj xeeb dhau los ua qhov cuam tshuam tsis tau rau qhov tseeb tseeb.
Cov kev daws teeb meem yog nyob rau hauv symbiotic engineering masterpiece: fusion ntawm Precision Granite Guides nrog Cua Bearing (Aerostatic) Technology.
Ntawm Unparalleled Group, peb tau paub txog kev kos duab ntawm kev sib koom ua ke ntawm ob lub thev naus laus zis no los tsim cov tshuab ua haujlwm uas muaj kev sib txhuam xoom, kev daws teeb meem tsis kawg, thiab tsis muaj qhov sib piv ntev - lub sij hawm ruaj khov. Kab lus no tshawb txog lub physics tom qab qhov fusion no thiab vim li cas nws thiaj li yog qhov tseem ceeb rau lub ntiaj teb cov cuab yeej tsim khoom siab tshaj plaws.
Lub Physics ntawm "Zero": Vim Li Cas Cua Bearings?
Txhawm rau ua kom tiav nanometer- theem qhov chaw, lub kaw lus yuav tsum tshem tawm lub tswv yim ntawm kev sib txhuam zoo li qub.
Rolling ntsiab tsis nyob ntawm no. Txawm tias qib siab tshaj plaws steel npas tau ntsib "stick-slip"- lub suab nrov uas tshwm sim los ntawm kev hloov pauv ntawm qhov zoo li qub mus rau kinetic kev sib txhuam. Qhov no tsim kev co thiab txwv kev daws teeb meem rau micro- nplai. Tsis tas li ntawd, dov kev sib cuag tsim microscopic hnav cov khoom, muaj kev pheej hmoo txaus ntshai hauv chav huv huv xws li semiconductor fabs.
Cua bearings daws qhov no los ntawm levitation.
Los ntawm kev siv cov cua compressed los ntawm cov xov xwm ntxeem tau lossis cov khoom sib cais rau hauv qhov sib txawv ntawm cov kabmob thiab cov lus qhia saum npoo, ib zaj duab xis nyias ntawm huab cua (feem ntau 5-20 microns tuab) yog tsim.
Zero Physical Contact: Cov theem txav ntab, tshem tawm txhua yam kev sib txhuam thiab hnav.
Infinite Resolution: Yog tsis muaj stick- plam, theem tuaj yeem txav mus ntxiv me me raws li tus encoder tuaj yeem ntes tau (feem ntau<1 nm).
Natural Damping: Lub viscous shear ntawm huab cua zaj duab xis muab damping zoo heev, smoothing tawm siab - zaus vibrations.
Kev huv huv: Tsis muaj kev sib cuag, tsis muaj cov khoom tsim tawm, ua rau nws zoo tagnrho rau ISO Class 1 cleanrooms.
Lub Foundation: Yog vim li cas Granite tsuas yog xaiv rau Cua Bearings
Thaum huab cua bearings muab cov txheej txheem rau kev sib txhuam tsis muaj zog, lawv xav tau cov lus qhia ntawm qhov zoo tshaj plaws los ua haujlwm kom raug. Qhov no yog qhov Precision Granite ua irreplaceable.
1. Qhov yuav tsum tau rau qhov kawg flatness thiab ncaj
Ib qho cua bearing qhov nruj thiab ruaj khov yog ncaj qha nyob ntawm qhov sib xws ntawm qhov sib txawv ntawm huab cua. Yog hais tias daim ntawv qhia saum npoo deviates los ntawm ob peb microns tshaj li ib 'meter' ntawm kev mus ncig, huab cua hloov pauv, ua rau theem "thaws" lossis qaij.
Granite qhov zoo: Cov pab pawg tsis sib xws ua cov txheej txheem granite rau Qib 000 (AAA) flatness thiab straightness tolerances (± 0.0005 mm / m lossis zoo dua). Qhov no geometric zoo meej ua kom muaj qhov sib txawv ntawm huab cua sib txawv, uas ua rau muaj kev nruj nruj thiab ua haujlwm zoo.
2. Thermal Stability yog Tsis yog -Ngotiable
Air bearing gaps yog microscopic. Thermal expansion ntawm cov kev taw qhia rail hloov qhov sib txawv, hloov cov kabmob qhov kev ua tau zoo thiab qhia txog qhov yuam kev.
Granite's Low CTE: Nrog rau Coefficient ntawm Thermal Expansion (CTE) kwv yees li ib nrab ntawm cov hlau thiab ib qho - thib peb ntawm txhuas, granite tseem nyob ruaj khov txawm tias qhov kub thiab txias hloov pauv hauv chav kuaj lossis fab. Qhov no ua kom paub tseeb tias tus nanometer- theem qhov tseeb qhov tseeb muaj tseeb dhau 24-teev kev ua haujlwm.
3. Damping thiab Vibration Isolation
Granite muaj lub peev xwm damping 10x ntau dua li cov hlau. Thaum ua ke nrog cov viscous damping ntawm huab cua zaj duab xis, lub kaw lus tsim ib qho "ob-damping" nyhuv. Qhov no cais cov rhiab heev payload (piv txwv li, ib kab hluav taws xob kab hluav taws xob lossis interferometer) los ntawm kev co hauv pem teb thiab lub suab nrov ntawm lub cev muaj zog, kom ntseeg tau tias nkig, plooj -dawb duab thiab ntsuas.
4. Corrosion Resistance thiab lub neej ntev
Tsis zoo li cov hlua hlau uas xav tau cov roj los yog cov txheej txheem tshwj xeeb los tiv thaiv xeb (uas tuaj yeem ua paug rau huab cua sib txawv), granite yog ib txwm tsis muaj zog. Nws tsis corrode, tsis outgas, thiab tswj nws qhov chaw ncaj ncees rau xyoo lawm, kom ntseeg tau tias huab cua bearing system ua tau zoo tib yam hauv Xyoo 10 raws li nws tau ua rau Hnub 1.
Txoj kev sib koom ua ke tsis sib xws: Engineering the Fusion
Tsim Granite Air Float Guide Rail system tsis yog hais txog kev txhim kho cov kabmob ntawm lub pob zeb. Nws xav tau ib txoj hauv kev tsim holistic uas Unparalleled Group tau refined ntau xyoo ntawm R & D.
Kauj Ruam 1: Precision Machining & Lapping
Peb siv lub xeev - ntawm - - kos duab CNC sib tsoo thiab phau ntawv lapping cov txheej txheem kom ua tiav nto tiav hauv qab Ra 0.1 µm. Qhov no ultra- du tiav yog qhov tseem ceeb rau kev tswj cov laminar ntws ntawm huab cua hauv qhov sib txawv ntawm cov kabmob. Txhua qhov chaw roughness tuaj yeem ua rau muaj kev kub ntxhov, ua rau muaj suab nrov thiab tsis ruaj khov.
Kauj ruam 2: Kinematic Mounting & Stress Relief
Granite yog nkig. Kev txhim kho tsis raug tuaj yeem ua rau muaj kev ntxhov siab sab hauv uas cuam tshuam cov lus qhia dhau sijhawm. Peb ntiav kinematic mounting cov hauv paus ntsiab lus thiab finite element tsom xam (FEA) los tsim cov qauv kev txhawb nqa uas tuav cov granite rigidly tsis inducing distortion. Peb Airy Point kev txhawb nqa suav kom paub tseeb tias cov lus qhia tseem nyob ncaj nraim hauv nws tus kheej qhov hnyav thiab kev thauj khoom ntawm lub sijhawm txav.
Kauj ruam 3: Custom Porous Media Integration
Rau qhov ruaj khov siab tshaj plaws, peb feem ntau sib xyaw cov porous graphite lossis tshwj xeeb ceramic txwv ncaj qha rau hauv lub tsheb sib tw, tsim tshwj xeeb kom phim cov kev cai permeability ntawm peb cov granite nto. Qhov no ua kom muaj kev sib faib ntawm huab cua siab thoob plaws tag nrho cov kabmob nto, ua kom muaj peev xwm ua haujlwm siab tshaj plaws thiab nruj.
Kauj ruam 4: System Calibration
Txhua lub axis sib sau ua ke tau txais laser interferometer calibration rau daim ntawv qhia suab, yaw, thiab yob yuam kev. Peb muab cov phiaj xwm them nyiaj uas tuaj yeem pub ncaj qha rau hauv cov tswj kev txav, thawb lub kaw lus kom raug rau hauv sub-100nm ntau yam dhau mus ntev.
Daim Ntawv Thov: Qhov twg Qhov Fusion no txhais lub Xeev - ntawm -the -Art
Kev sib xyaw ua ke ntawm Precision Air Bearings thiab Granite Guides yog tus qauv kub rau kev lag luam uas tsis ua haujlwm tsis yog qhov kev xaiv:
Semiconductor Wafer Inspection & Metrology: Qhov tseem ceeb rau kev tshuaj ntsuam xyuas electron microscopes (SEM) thiab cov cuab yeej kho qhov muag overlay qhov twg theem kev co ua rau cov duab daws teeb meem.
Photolithography Mask Stages: Yuav tsum muaj kev nrawm nrawm nrog nanometer daws qhov tseeb; tsuas yog cua / granite tshuab tuaj yeem tswj cov kev hloov pauv yam tsis muaj hnav.
Ultra-Precision pob zeb diamond tig: Ua kom lub machining ntawm freeform optics nrog nto roughness nyob rau hauv lub angstrom ntau yam.
Coordinate Measuring Machines (CMM): Siab -CMMs kawg siv cov thev naus laus zis no kom ua tiav qhov tseeb volumetric yav dhau los xav tias ua tsis tau.
Xaus: Tsim Txoj Kev mus rau Nanoscale
Raws li qhov xav tau ntawm Moore Txoj Cai thiab cov ntaub ntawv qib siab kev tshawb fawb thawb peb tob rau hauv nanoscale, cov khoom peb xaiv yuav tsum hloov zuj zus. Kev sib yuav ntawm granite lub hauv paus ruaj khov thiab huab cua kev sib txhuam tsis muaj kev ywj pheej tsis yog kev hloov kho xwb; nws yog ib qho tsim nyog rau tiam tom ntej ntawm precision machinery.
Ntawm Unparalleled Group, peb tsis yog muab pob zeb xwb; peb engineer motion ecosystems. Los ntawm cov chaw txua txiag zeb mus rau qhov kawg calibrated axis, peb xyuas kom meej tias txhua micron ntawm kev mus los yog tswj, ruaj khov, thiab meej.
