Nyob rau hauv lub ntiaj teb ntawm ultra - precision raug, granite yog cov khoom siv uas nyiam rau tshuab hauv paus, platforms, thiab cov qauv txheej txheem. Nws qhov kev co kom ruaj khov thiab ntuj kev co damping zog ua rau nws lub hauv paus zoo tshaj plaws rau ntau cov ntawv thov kev lag luam, los ntawm CNC machining kom dav metrology. Txawm li cas los xij, thaum nws los txog rau kev kho qhov muag thiab laser {{{} raws cov kab ke, qhov yuav tsum tau ua rau lub platform granite ua yeeb yam. Dab tsi yuav ua rau muaj kev lag luam txaus cas tsuas yog tsis txaus rau qhov system uas ntsuas nrog lub teeb.
Xaiv cov pob zeb pob zeb rau kho qhov muag metrology tsis yog cov khoom lag luam yuav khoom; Nws yog cov kev txiav txim siab tshwj xeeb engineering uas xav tau kev nkag siab tob ntawm cov khoom siv, kev tsim qauv, thiab tsim khoom. Cov kev sib tw tshwj xeeb posed los ntawm lub teeb - raws li kev ntsuas yuav tsum tau ntsuas qhov tseeb tias ob peb tus qauv platform tau muab.
Qhov tshwj xeeb ntawm kev siv kho qhov muag
Tsis zoo li ib txwm ua cartminate ntsuas ntsuas lub tshuab ntsuas (CMM) uas siv tshuaj ntsuam xyuas lub cev, lub teeb tsom iav kho kom zoo nkauj, lossis lwm lub teeb}} Qhov kev hloov tshiab no hauv txoj kev tswj hwm tus tswv ntawm cov kev sib tw tshiab uas cuam tshuam rau lub platform yuav tsum muaj:
Kev co rhiab rhiab: lub teeb yog qhov tsis tshua muaj peev xwm rau txawm tias feem ntau minuscule vibrations. Lub tshuab tsom me me uas yuav tsis pom ntawm cov kws kho tshuab CMM tuaj yeem ua rau lub ntsej muag zoo nkauj, ib qho kev ntsuas laser kom tsis ruaj khov.
Thermal Drift: Lub teeb focal focal thiab tus sensor txoj haujlwm yog rhiab heev rau qhov kub hloov. Tus qauv kev lag luam hauv paus yuav nthuav tawm lossis ntawv cog lus me ntsis rau txoj kev kub ntxhov, tab sis qhov no ua rau focal drift thiab ntsuas tsis raug nyob rau hauv micron thiab sau} micron ntau.
Kev sib xyaw ua ke: kev ua ke kho qhov muag feem ntau ua ke siab {{}}} ceev cov tshuab ceev (ib txwm muaj cov tshuab ooi) thiab cov pob txha ceev. Cov khoom sib xyaw no qhia lawv tus kheej qis - profile deeg thiab yuav tsum muaj tus tiaj tus, meej, thiab ruaj khov rau saum toj kom raug.
Cov Khoom Siv Cov Khoom Siv: Lub Pob Txheem ntawm ib qho kho qhov muag
Rau lub tshuab kho qhov muag kho qhov muag, cov khoom nws tus kheej yog thawj qhov kev tiv thaiv thawj zaug ntawm cov kev cov nyom no. Thaum twg ib qho precision -}}}} {{{2} {{sib ceg tau rau cov ntawv thov optical.
Zoo dua li cov khoom tseem ceeb tshaj plaws yog qhov siab damping coefficient. Granite lub peev xwm ntuj los nqus tau vibrations yog txhim kho los ntawm qhov siab ntom ntom thiab nplua- nplej microstructed microstructure. Qhov no tso cai rau cov khoom siv kom dissipate lub metcopic dibrations los ntawm ib puag ncig lossis cov kev siv tshuab sab hauv ua ntej lawv tuaj yeem ua rau muaj kev ntsuas kho kom meej thiab ruaj khov.
Tshwj xeeb ntawm thermal stability: granite platform nrog ib tug heev coefficient ntawm thermal expansion (CTE) yog qhov tseem ceeb. Txog kev kho qhov muag, thermal stability yog qhov ntsuas kom tswj cov kev sib ncag ntawm txhua qhov kho kho qhov muag, ntawm lub teeb ci rau lub sensor. Siab -} Zoo dub granite, vim nws ntom nti, ua rau muaj kev hloov pauv ntau yam, uas yog qhov tseem ceeb rau kev siv dag zog nyob hauv ib puag ncig lab.
Cov khoom siv no muaj ntau dua qhov tseem ceeb rau lub zog kho qhov muag, qhov twg txhav txhav txhav lug
Tsim thiab tsim khoom: Engineering rau Lub Teeb
Dhau ntawm cov khoom siv raw, tus qauv thiab tsim cov khoom siv granite rau kev soj ntsuam kho mob yuav tsum ua raws li cov qauv siab ntawm precision.
Kev ua kom tsis muaj qab hau: Thaum qib 1 lub platform yuav muaj feem ntau ntawm cov qauv hluav taws xob rau qhov ntsuas qhov ntsuas kom muaj qhov tsawg kawg nkaus.
Kev co kev sib cais cov yam ntxwv: ib qho tshwj xeeb optical platform yog feem ntau tau tsim los ua ke nrog sab nraud kev co tshuab, xws li bearings cua. Qhov no yuav tsum muaj lub platform nws tus kheej ua tau machined nrog txawv tshaj plaw, suav nrog cov chaw tiaj tus mounting chaw thiab precisely dricked qhov rau cov cua pads.
Complex machining: platform tsim kho tshiab feem ntau muaj cov cim kev ua si thiab cov khoom sib xyaw. Qhov no suav nrog precision - kev txiav tawm rau mounting ntau yam, txhua yam yuav tsum muaj cov peev xwm cnc tshwj xeeb thiab cov kws tshaj lij craftsmanship.
Kev lag luam -} coj kho qhov muag tau lees paub qhov no xav tau kev tsim tshwj xeeb. "Peb tsis tuaj yeem tso peb lub kaw lus tua hluav taws xob slab thiab cia siab tias nws yuav tsum tau ua haujlwm zoo rau cov qauv hluav taws xob ruaj khov.
Tus khub zoo rau koj daim ntawv thov kho qhov muag
Qhov sib txawv ntawm tus qauv kev lag luam granite platform thiab ib qho tsim rau kev soj ntsuam kho qhov muag tsis yog tsuas yog muaj teeb meem ntawm tus nqi {} Nws yog qhov teeb meem ntawm kev ua tau zoo thiab kev ntseeg tau. Rau cov engineers thiab cov neeg tsim qauv ntawm kho qhov muag lub tshuab, tus neeg xa khoom cov kev txawj ntse tseem ceeb npaum li cov khoom nws tus kheej.
Tus khub zoo tshaj plaws rau cov teb tshwj xeeb no yog ib qho uas:
Nkag siab txog lub cev ntawm koj daim ntawv thov: Lawv yuav tsum muaj peev xwm los tham txog koj qhov kev sib txawv ntawm koj qhov kev kho qhov muag, los ntawm lub teeb kev ruaj ntseg mus rau kev tswj hwm kev co.
Kev Txhawb Nqa Cov Khoom Siv Tsim Lag Luam: Lawv yuav tsum muaj lub sijhawm ua kom haum, ntsuas kub tas li yog tsim tawm hauv cov xwm txheej ruaj khov, nrog metrology tracts.
Muaj cov cav tov ua tau zoo heev: lawv yuav tsum tau coj cov geometries thiab ultra {{0} kev ua kom muaj txiaj ntsig los sib xyaw nrog koj lub kaw lus siab tshaj.
Nyob rau hauv ib daim teb uas ib micron tuaj yeem yog qhov sib txawv ntawm cov khoom lag luam zoo thiab tsis ua hauj lwm, nqis peev rau cov khoom siv tshuaj ntsuab tsis yog khoom kim heev} nws yog qhov yuav tsum tau ua.
