Hauv plawv ntawm kev lag luam uas muaj kev ntsuas siab heev—txij li kev tsim khoom siv semiconductor mus rau kev ntsuas dav hlau—yog lub platform granite. Feem ntau tsis quav ntsej li ib lub pob zeb khov kho, qhov khoom no, qhov tseeb, yog lub hauv paus tseem ceeb thiab ruaj khov tshaj plaws rau kev ua tiav kev ntsuas thiab kev tswj kev txav mus los. Rau cov engineers, metrologists, thiab cov neeg tsim tshuab, kev nkag siab txog qhov tseeb ntawm "kev ntsuas" ntawm lub platform granite yog qhov tseem ceeb heev. Nws tsis yog hais txog qhov tiav ntawm qhov chaw xwb; nws yog hais txog cov cim geometric uas qhia txog kev ua haujlwm tiag tiag ntawm lub platform.
Cov cim qhia tseem ceeb tshaj plaws ntawm lub platform granite qhov tseeb yog Flatness, Straightness, thiab Parallelism, txhua yam uas yuav tsum tau txheeb xyuas raws li cov qauv thoob ntiaj teb.
Kev Tiaj: Lub Dav Hlau Siv Tau Zoo Tshaj Plaws
Qhov tiaj tiaj yog qhov qhia tseem ceeb tshaj plaws rau txhua lub platform granite precision, tshwj xeeb tshaj yog Granite Surface Plate. Nws txhais tau tias tag nrho qhov chaw ua haujlwm sib raug zoo li cas rau lub dav hlau zoo meej theoretical. Hauv qhov tseem ceeb, nws yog qhov siv los ntawm txhua qhov kev ntsuas lwm yam.
Cov chaw tsim khoom xws li ZHHIMG ua kom tiaj tiaj los ntawm kev ua raws li cov qauv thoob ntiaj teb xws li DIN 876 (Lub Tebchaws Yelemees), ASME B89.3.7 (Tebchaws USA), thiab JIS B 7514 (Nyiv Pooj). Cov qauv no txhais cov qib kev kam rau siab, feem ntau yog txij li Qib 00 (Qib Kuaj Mob, xav tau qhov tseeb siab tshaj plaws, feem ntau nyob rau hauv sub-micron lossis nanometer ntau yam) mus rau Qib 1 lossis 2 (Qib Tshuaj Xyuas lossis Chav Siv). Kev ua tiav qib kev tiaj tiaj hauv chav kuaj mob tsis yog tsuas yog xav tau kev ruaj khov ntawm cov granite siab ceev xwb tab sis kuj tseem muaj kev txawj ntse tshwj xeeb ntawm cov kws tshaj lij lappers - peb cov kws ua haujlwm uas tuaj yeem ua tiav cov kev kam rau siab no nrog qhov tseeb feem ntau hu ua "micrometer xav."
Kev Ncaj Ncees: Lub hauv paus ntawm Kev Tawm Tsam Linear
Txawm hais tias qhov tiaj tiaj yog hais txog thaj chaw ob-seem, Qhov Ncaj Ncees siv rau ib txoj kab tshwj xeeb, feem ntau raws ntug, cov lus qhia, lossis qhov ntawm cov khoom granite zoo li ntug ncaj, plaub fab, lossis lub hauv paus tshuab. Hauv kev tsim tshuab, qhov ncaj yog qhov tseem ceeb vim nws lav qhov tseeb, txoj kev ncaj ntawm cov kab txav mus los.
Thaum siv lub hauv paus granite los teeb tsa cov lus qhia linear lossis cov kabmob cua, qhov ncaj ntawm cov nplaim mounting ncaj qha txhais mus rau qhov yuam kev linear ntawm theem txav mus los, cuam tshuam rau qhov tseeb ntawm qhov chaw thiab rov ua dua. Cov txheej txheem ntsuas siab heev, tshwj xeeb tshaj yog cov uas siv laser interferometers (ib feem tseem ceeb ntawm ZHHIMG txoj cai tshuaj xyuas), yuav tsum tau lees paub qhov sib txawv ntawm qhov ncaj hauv thaj chaw ntawm micrometers ib 'meter', kom ntseeg tau tias lub platform ua haujlwm ua lub hauv paus zoo tshaj plaws rau cov kab ke txav mus los.
Kev Sib Npaug thiab Kev Sib Npaug: Txhais Kev Sib Haum Xeeb Geometric
Rau cov khoom granite nyuaj, xws li lub hauv paus tshuab, cov lus qhia cua, lossis ntau qhov chaw xws li granite squares, ob qho cim ntxiv tseem ceeb heev: Parallelism thiab Perpendicularity (Squareness).
- Kev sib luag qhia tias ob lossis ntau qhov chaw - xws li cov chaw teeb tsa sab saud thiab hauv qab ntawm lub nqaj granite - yog sib npaug zos ntawm ib leeg. Qhov no yog qhov tseem ceeb rau kev tswj qhov siab ua haujlwm tas li lossis xyuas kom meej tias cov khoom ntawm sab nraud ntawm lub tshuab tau sib dhos zoo.
- Perpendicularity, lossis squareness, ua kom ob qhov chaw yog 90 ° rau ib leeg. Hauv lub Tshuab Ntsuas Coordinate (CMM), tus kav granite square, lossis lub hauv paus nws tus kheej, yuav tsum tau lees tias perpendicularity kom tshem tawm Abbe yuam kev thiab lav tias X, Y, thiab Z axes yog orthogonal tiag tiag.
Qhov Sib Txawv ntawm ZHHIMG: Tshaj Qhov Tshwj Xeeb
Ntawm ZHHIMG, peb ntseeg tias qhov tseeb tsis tuaj yeem teev ntau dhau - Kev lag luam precision tsis tuaj yeem ua kom nyuaj dhau. Peb txoj kev cog lus mus dhau qhov ua tau raws li cov qauv no. Los ntawm kev siv ZHHIMG® Black Granite uas muaj qhov ceev ceev (≈ 3100 kg / m³), peb cov platforms muaj kev co zoo dua thiab qhov coefficient thermal expansion qis tshaj plaws, tiv thaiv qhov tiaj tiaj, ncaj, thiab sib luag ntawm kev cuam tshuam ib puag ncig thiab kev ua haujlwm.
Thaum soj ntsuam lub platform granite precision, tsis yog tsuas yog saib daim ntawv qhia xwb tab sis kuj saib qhov chaw tsim khoom, cov ntawv pov thawj, thiab kev tswj xyuas zoo - cov ntsiab lus uas ua rau ZHHIMG® Cheebtsam yog qhov kev xaiv ruaj khov thiab txhim khu kev qha tshaj plaws rau lub ntiaj teb cov ntawv thov ultra-precision tshaj plaws.
