Thaum tsim cov khoom precision, XY precision worktable zoo li "super craftsman", lub luag haujlwm rau kev sib tsoo cov khoom kom zoo ib yam. Tab sis qee zaum, txawm tias kev ua haujlwm zoo, cov khoom tsim tawm tsis tau raws li tus qauv. Qhov no tej zaum yuav yog vim lub hauv paus granite ntawm lub workbench yog "nthuav tantrum"! Niaj hnub no, cia peb tham txog qhov tseem ceeb npaum li cas ntawm cov khoom siv hauv granite yog rau kev ua tiav.
Cov khoom siv yog "tsis sib xws", thiab qhov teeb meem tau tawg
Xav txog lub hauv paus granite, qee qhov nyuaj thiab qee qhov yog mos; Yuav ua li cas yog tias qee qhov chaw nthuav dav ntxiv thaum cua sov thiab qee qhov chaw nthuav tsawg dua?
Kev vibration tsis sib xws: Yog tias qhov ceev ntawm qhov sib txawv ntawm lub tshuab granite lub hauv paus tsis zoo ib yam, thaum lub rooj ua haujlwm txav nrawm, nws yuav zoo li tus neeg taug kev, ib qho siab thiab qis, ua rau tshee. Hom kev co no yog qhov hnyav heev hauv kev ua haujlwm precision. Piv txwv li, thaum polishing optical lo ntsiab muag, nws yuav ua rau lub ntsej muag ntawm lub lo ntsiab muag ua ntxhib. Cov tsom iav uas tuaj yeem ua tiav cov duab zoo li iav yuav ua rau lawv cov khoom seem nce siab los ntawm 30% ncaj qha!
Kub "ua rau muaj teeb meem": Nyob rau hauv cov txheej txheem semiconductor photolithography, yuav tsum tau tswj kom meej ntawm txoj hauj lwm. Txawm li cas los xij, yog tias cov thermal expansion coefficients ntawm thaj chaw sib txawv ntawm lub hauv paus granite sib txawv heev, thaum qhov kub thiab txias hloov, lub hauv paus yuav "deform thiab distort", uas ua rau qhov loj dua qhov yuam kev thiab tej zaum tag nrho wafer raug muab pov tseg.
Kev hnav tsis sib xws: Lub hauv paus nrog cov tawv tawv tsis sib xws yog zoo li nkawm khau nrog ntau qib hnav. Tom qab siv sijhawm ntev, qhov chaw uas muaj zog qis dua ntawm qhov chaw ua haujlwm yuav raug hnav sai dua. Txoj kev ncaj nraim ntawm qhov qub yuav dhau los ua nkhaus, thiab qhov ncaj yuav poob qis. Tus nqi saib xyuas kuj tseem yuav nce siab.
Tsuas yog thaum cov ntaub ntawv zoo ib yam tuaj yeem ua haujlwm ruaj khov li Mount Tai.
Thaum cov khoom siv ntawm lub hauv paus granite zoo ib yam thiab zoo ib yam, cov txiaj ntsig yog tam sim no:
ruaj khov, raug thiab muaj zog dynamic kev ua tau zoo: Lub hauv paus ua los ntawm cov ntaub ntawv zoo ib yam tuaj yeem nqus kev co thaum lub rooj ua haujlwm pib, nres lossis tig nrawm. Nyob rau hauv txoj kev no, qhov rov ua qhov tseeb qhov tseeb tuaj yeem ncav cuag qhov xav tsis thoob ± 0.3μm, uas yog sib npaug rau qhov tseeb ntawm kev faib tib neeg cov plaub hau rau hauv 300 ntau qhov chaw!
Cov lus teb qhov kub thiab txias: Ib qho kev sib koom ua ke ntawm thermal expansion yog zoo li txhim kho "kev tswj qhov kub thiab txias" ntawm lub hauv paus. Cov kws tshaj lij tuaj yeem kwv yees qhov tseeb ntawm qhov deformation ntawm lub hauv paus thaum qhov kub hloov pauv. Los ntawm kev them nyiaj algorithm, thermal deformation yuam kev yog tswj tsis pub dhau ± 0.5μm.
Ntxiv-ntev "kev pab cuam lub neej": Uniform hardness thiab ntom kom ntseeg tau tias txhua qhov chaw ntawm lub hauv paus yog "txoj kev nyuaj siab", tsis txhob hnav ntau dhau hauv zos. Lub hauv paus tshuab ib txwm yuav tsum tau hloov txhua tsib xyoos, thaum cov khoom zoo uas ua los ntawm cov ntaub ntawv zoo ib yam tuaj yeem siv tau rau yim mus rau kaum xyoo, txuag nyiaj ntau ntawm cov khoom siv hloov pauv.
Yuav ua li cas xaiv ib lub "txhim khuav" granite aircraft puag?
Txheeb xyuas qhov "keeb kwm" : Xaiv granite mined los ntawm tib cov ntxhia txheej thiab tib cheeb tsam, ib yam li khaws cov txiv hmab txiv ntoo los ntawm tib tsob ntoo, qhov no tuaj yeem xyuas kom meej tias cov ntxhia muaj pes tsawg leeg zoo sib xws.
Kev nruj "kev kuaj lub cev": Kev ntseeg siab ntawm granite tshuab hauv paus yuav tsum mus dhau 12 "checkpoints" xws li spectral tsom xam thiab ntsuas qhov ceev, thiab tag nrho cov khoom siv tsis zoo raug tshem tawm.
Kos "ID card": Nug tus neeg muag khoom kom muab cov ntawv pov thawj zoo thiab cov ntawv xeem. Tsuas yog lub hauv paus nrog cov ntawv pov thawj pom zoo tuaj yeem siv nrog kev thaj yeeb nyab xeeb dua.
Nyob rau hauv lub ntiaj teb no ntawm precision machining, cov ntsiab lus txiav txim siab zoo los yog tsis ua hauj lwm. Cov khoom sib xws ntawm lub hauv paus granite yog qhov txuas tseem ceeb los xyuas kom meej qhov tseeb thiab txo cov nqi. Lwm zaus thaum xaiv cov khoom siv, tsis txhob saib qhov "me ntsis nthuav dav" dua!
