Koj tau nqis peev hauv qhov hwm precision granite nto phaj. Daim ntawv pov thawj ntawm kev tshuaj xyuas qhia tau hais tias zoo meej flatness, thiab cov khoom yog sab saum toj -qib dub granite. Txawm li cas los xij, rau lub hlis tom qab, koj lub chaw kuaj ntsuas ntsuas ntsuas cov ntaub ntawv tsis sib haum, lossis koj cov kab sib dhos tau tsim cov khoom uas tsis tau piav qhia.
Qhov teeb meem feem ntau tsis yog cov khoom siv - nws yog cov txheej txheem installation thiab commissioning.
Lub siab -precision granite phaj yog cov cuab yeej rhiab heev. Txawm tias lub ntiaj teb lub pob zeb zoo tshaj plaws yuav cuam tshuam yog tias muab tso rau hauv pem teb tsis ruaj khov lossis txhawb nqa tsis raug. Ntawm Unparalleled Group, peb tau pom ntau qhov xwm txheej uas "cov khoom lag luam zoo" ua tsis tiav vim kev teeb tsa tsis raug.
Hauv phau ntawv qhia no, peb rhuav tshem 4 cov kauj ruam tseem ceeb rau kev txhim kho thiab ua haujlwm ntawm koj lub granite nto phaj, xyuas kom koj ua tiav thiab tuav qhov kev ua tsis ncaj ntawm tsawg dua lossis sib npaug li 0.003mm / m (Class 00). Txawm hais tias koj tab tom teeb tsa lub chaw kuaj ntsuas tshiab lossis hloov kho lub xov tooj ntawm tes, ua raws li cov txheej txheem no yog qhov txawv ntawm qhov tseeb thiab kev ntxhov siab.
Kauj Ruam 1: Kev Npaj Foundation - Lub Hauv Paus Tsis Pom
Ua ntej lub phaj granite puas tau kov hauv pem teb, lub hauv paus yuav tsum tau npaj. Lub ntiajteb txawj nqus thiab kev co yog cov yeeb ncuab ntawm flatness.
Qhov Yuav Tsum Tau
Structureal Integrity: Hauv pem teb yuav tsum muaj cov pob zeb ua kom muaj zog txaus -cov kabmob muaj peev xwm tiv thaiv kev daws teeb meem. Lub vibrating lossis flexing pem teb hloov kev ntxhov siab ncaj qha mus rau granite.
Kev rho tawm kev vibration: Rau ultra- daim ntawv thov precision (tsawg dua lossis sib npaug li 0.003mm / m), active lossis passive anti- vibration pads yog qhov yuav tsum tau ua. Ambient vibrations los ntawm cov forklifts nyob ze, nias, lossis HVAC cov tshuab tuaj yeem ua rau micro- txav mus los uas cuam tshuam kev ntsuas rov ua dua.
Leveling Base: Nruab ib lub thav duab steel robust lossis adjustable pedestal system ua ntej muab granite. Cov thav duab no yuav tsum tau nyob rau hauv 0.1mm / m ntawm nws tus kheej.
⚠️ Feem ntau yuam kev: Tsis quav ntsej Pem Teb Gradints
Ntau qhov chaw nruab cov phaj ncaj qha rau ntawm cov txheej txheem rhiav. Sij hawm dhau mus, kev hloov hauv av raws caij nyoog lossis kev tsheb hnyav ua rau hauv pem teb tig me ntsis. Qhov no induces torsional kev nyuaj siab nyob rau hauv granite, ua rau mus tas li deformation.
Pro Tip: Siv lub ntsuas ntsuas digital los qhia cov gradient hauv pem teb dhau 24 teev ua ntej kev teeb tsa. Yog tias qhov kev hloov pauv ntau dua 0.05mm / m, ntxiv dag zog rau lub hauv paus ua ntej.
Kauj Ruam 2: Daim Duab Ntawm Peb -Point Support (Airy Points)
Yuav ua li cas koj txhawb lub phaj yog ib qho tseem ceeb raws li lub phaj nws tus kheej. Granite yog hnyav; yog tias kev txhawb nqa tsis raug, nws sags hauv nws qhov hnyav.
Physics of Support
Txhawm rau txo qis kev nqus dej, cov ntsiab lus txhawb nqa yuav tsum nyob ntawm cov haujlwm tshwj xeeb hu ua Airy Points (rau qhov nqes qis kawg ntawm qhov kawg) lossis Bessel Cov Ntsiab Lus (rau qhov hloov pauv tsawg kawg). Rau cov phaj saum npoo, tus qauv feem ntau yog ob qho kev txhawb nqa ntawm 2/9 ntawm tag nrho qhov ntev ntawm txhua qhov kawg, nrog rau peb lub hauv paus kev txhawb nqa rau kev ruaj ntseg ntawm daim hlau loj.
Tus txheej txheem
Ntxuav lub hauv qab: xyuas kom cov hauv qab ntawm granite thiab cov ntaub qhwv tsis muaj plua plav lossis khib nyiab. Txawm tias 10μm particle tuaj yeem tsim qhov pivot taw tes ua rau muaj kev cuam tshuam.
Kev Txhawb Txoj Haujlwm: Kos lub 2/9 txoj haujlwm kom meej. Siv adjustable leveling taw nrog spherical bearings tso cai rau tus kheej -alignment.
Pib Leveling: Kho ob txhais taw kom txog thaum lub phaj yog horizontally. Tsis txhob overtighten, uas tuaj yeem nqa qhov chaw thiab tsim kom muaj "dome" nyhuv.
⚠️ Feem ntau yuam kev: Plaub-Keb" ntxiab
Ib qho yuam kev tsis tu ncua hauv granite phaj installation yog txhawb lub phaj ntawm tag nrho plaub fab. Qhov no tsim ib qho "qos yaj ywm chip" qhov twg qhov chaw sags vim tsis muaj kev txhawb nqa, instantly ua txhaum tus qauv flatness.
Cov ntaub ntawv Point: A 1000x1000mm Class 00 phaj txhawb nqa ntawm plaub lub kaum ntse ntse tuaj yeem pom qhov chaw nruab nrab txog li 5-8μm, ua rau nws tsis muaj txiaj ntsig rau kev ua haujlwm siab -. Ib txwm siv cov ntsiab lus Airy/Bessel suav.
Kauj Ruam 3: Thermal Stabilization - Kev Ua Si Tos
Granite muaj cov coefficient tsawg ntawm thermal expansion, tab sis nws tsis tiv thaiv qhov kub thiab txias. Tsiv lub phaj los ntawm lub warehouse txias mus rau ib qho chaw sov so, los yog txawm lub tshav kub los ntawm kev tuav, ua rau ib ntus nthuav.
Txoj Cai
Lub Sijhawm Acclimatization: Thaum muab tso rau, lub phaj yuav tsum nyob twj ywm rau 24 mus rau 48 teev (nyob ntawm seb huab hwm coj) kom ncav cuag thermal sib npaug nrog chav.
Environmental Control: Chav tsev kub yuav tsum ruaj khov ntawm 20℃± 1℃(ISO 1 tus qauv). Tsis txhob tshav ntuj ncaj qha, AC qhov cua tshuab ncaj qha rau ntawm lub pob zeb, lossis qhov chaw sov nyob ze.
Tuav Hniav: Thaum lub sijhawm no, cov neeg ua haujlwm yuav tsum hnav hnab looj tes. Lub cev kub hloov mus rau saum npoo tuaj yeem tsim cov chaw kub hauv zos uas skew pib nyeem ntawv.
⚠️ Feem ntau yuam kev: Rushing Calibration
Cov kws kho mob feem ntau mob siab pib ua haujlwm yuav pib calibration tam sim ntawd tom qab tso. Qhov no ua rau kev nyeem tsis tseeb. Raws li lub pob zeb maj mam nthuav los yog cog lus kom haum rau chav tsev, qhov kev ua yuam kev flatness drifts, invalidating thawj calibration. Kev ua siab ntev ntawm no txuag cov hnub ntawm kev rov ua haujlwm tom qab.
Kauj Ruam 4: Laser Interferometer Calibration & Kev Tshawb Fawb Kawg
Cov kauj ruam kawg yog txheeb xyuas qhov kev teeb tsa tawm tsam granite phaj flatness tus qauv siv lub xeev - ntawm - cov khoom siv kos duab. Thaum cov tshuaj autocollimators ua tau zoo, laser interferometry muaj kev daws teeb meem zoo tshaj plaws rau kev ua tiav tsawg dua lossis sib npaug li 0.003mm / m.
Cov txheej txheem Calibration
Grid Mapping: Txhais ib daim phiaj ntsuas (piv txwv li, 5x5 lossis 10x10 ntsiab lus) hla tag nrho saum npoo.
Kev teeb tsa Laser: Mount lub taub hau laser thiab lub teeb pom kev ntawm tus choj ruaj khov lossis lub tsheb thauj khoom uas txav hla lub phaj yam tsis tas kov qhov ntsuas qhov chaw.
Kev Sau Cov Ntaub Ntawv: Ntsuas qhov siab sib txawv ntawm txhua qhov kab sib chaws. Lub kaw lus suav qhov zoo tshaj plaws - haum dav hlau thiab txiav txim siab qhov siab tshaj plaws - mus rau - hav yuam kev.
Fine Tuning: Yog tias qhov yuam kev dhau qhov txwv, ua micro- hloov kho rau cov ko taw kev txhawb nqa raws li daim ntawv qhia kev ua yuam kev (xws li, yog qhov chaw qis, me ntsis tsa lub hauv paus kev txhawb nqa).
Daim ntawv pov thawj: Tsim ib daim ntawv qhia digital contour thiab daim ntawv pov thawj calibration traceable rau lub teb chaws tus qauv.
⚠️ Feem ntau yuam kev: tsis saib xyuas rov ua dua
Ib qho dhau los tsis txaus. Ua qhov ntsuas peb zaug, tshem tawm thiab hloov qhov kev sojntsuam / nqa ntawm kev khiav. Yog tias cov txiaj ntsig sib txawv ntau dua 0.5μm, tshawb xyuas cov teeb meem kev co lossis thermal instability ua ntej kos npe tawm.
Vim li cas Precision Matters: Tus nqi ntawm kev teeb tsa tsis raug
Rau cov chaw soj ntsuam metrology thiab siab - thev naus laus zis cov tuam txhab, lub phaj saum npoo yog qhov tseeb siv rau txhua qhov dej ntws zoo.
Scenario A: Cov chaw tsim khoom siv hluav taws xob semiconductor teeb tsa lub phaj tsis raug. Qhov tshwm sim: Wafers yog machined nrog 4μm hneev. Tag nrho batch scrapped. Nqe: $50,000+.
Scenario B: Ua raws li Pawg Neeg Tsis Txaus Siab 4-kauj ruam qhia. Qhov tshwm sim: ruaj khov flatness ntawm 0.002mm / m khaws cia rau 5 xyoos. Zero scrap vim qhov yuam kev hauv paus.
Kev nqis peev lub sij hawm hauv cov txheej txheem granite phaj calibration kom zoo them cov nyiaj faib tawm hauv cov khoom lag luam zoo thiab lub koob npe nrov.
