Nyob rau hauv lub plawv ntawm ultra-precision kev lag luam - los ntawm semiconductor manufacturing rau aerospace metrology - yog cov granite platform. Feem ntau overlooked tsuas yog ib qho khoom thaiv ntawm pob zeb, qhov kev tivthaiv no yog, qhov tseeb, lub hauv paus tseem ceeb tshaj plaws thiab ruaj khov rau kev ua tiav cov kev ntsuas raug thiab tswj kev txav. Rau engineers, metrologists, thiab tshuab builders, to taub dab tsi tiag tiag txhais lub "precision" ntawm granite platform yog qhov tseem ceeb. Nws tsis yog tsuas yog hais txog qhov chaw tiav; nws yog hais txog ib phau ntawm cov ntsuas geometric uas qhia lub platform qhov kev ua tau zoo hauv ntiaj teb.
Cov cim tseem ceeb tshaj plaws ntawm granite platform qhov precision yog Flatness, Ncaj, thiab Parallelism, tag nrho cov uas yuav tsum tau txheeb xyuas cov qauv thoob ntiaj teb nruj.
Flatness: Master Reference Plane
Flatness yog arguably ib qho tseem ceeb tshaj plaws qhia rau tej precision granite platform, tshwj xeeb tshaj yog ib tug Granite nto phaj. Nws txhais tau tias ze li cas tag nrho cov chaw ua haujlwm ua raws li lub dav hlau theoretical zoo meej. Hauv qhov tseeb, nws yog tus tswv siv los ntawm txhua qhov kev ntsuas tau coj los.
Cov neeg tsim khoom zoo li ZHHIMG ua kom lub tiaj tiaj los ntawm kev ua raws li cov qauv kev lees paub thoob ntiaj teb xws li DIN 876 (Lub Tebchaws Yelemees), ASME B89.3.7 (USA), thiab JIS B 7514 (Nyiv). Cov qauv no txhais cov qib kam rau ua, feem ntau muaj xws li Qib 00 (Kev Tshawb Fawb Qib, xav tau qhov siab tshaj plaws, feem ntau nyob rau hauv sub-micron lossis nanometer range) mus rau Qib 1 lossis 2 (Kev Tshawb Fawb lossis Chav Kawm Qib). Kev ua tiav qhov chaw kuaj-qib flatness yuav tsum tsis yog tsuas yog kev ruaj ntseg ntawm cov granite high-density tab sis kuj yog qhov tshwj xeeb ntawm cov tswv lappers - peb cov kws ua haujlwm uas tuaj yeem ua tiav cov kev ua siab ntev no nrog qhov tseeb feem ntau hu ua "micrometer xav."
Kev Ncaj Ncees: Lub Ncauj Ncauj Ncaj Ncees
Thaum flatness hais txog thaj tsam ob sab, Ncaj ncaj siv rau ib txoj kab tshwj xeeb, feem ntau raws cov npoo, cov lus qhia, lossis cov qhov ntawm cov khoom siv granite xws li ntug ncaj, square, lossis tshuab puag. Hauv kev tsim tshuab, kev ncaj nraim yog qhov tseem ceeb vim tias nws lav qhov tseeb, txoj hauv kev ntawm cov lus tsa suab.
Thaum lub hauv paus granite yog siv los mount linear qhia los yog huab cua bearings, qhov ncaj ntawm qhov chaw mounting ncaj qha mus rau linear yuam kev ntawm qhov txav mus, cuam tshuam qhov chaw qhov tseeb thiab rov ua dua. Cov txheej txheem ntsuas qib siab, tshwj xeeb tshaj yog cov siv laser interferometers (ib feem tseem ceeb ntawm ZHHIMG qhov kev soj ntsuam raws tu qauv), yuav tsum tau lees paub qhov ncaj sib txawv hauv thaj tsam ntawm micrometers ib 'meter', ua kom lub platform ua raws li cov pob txha tsis zoo rau cov tshuab dynamic.
Parallelism thiab Perpendicularity: Defining Geometric Harmony
Rau cov khoom siv granite nyuaj, xws li tshuab hauv paus, cov lus qhia huab cua, lossis ntau qhov chaw zoo li granite squares, ob qhov ntsuas ntxiv yog qhov tseem ceeb: Parallelism thiab Perpendicularity (Squareness).
- Parallelism dictates tias ob los yog ntau qhov chaw - xws li sab saum toj thiab hauv qab mounting nto ntawm granite beam - yog raws nraim equidistant ntawm ib leeg. Qhov no yog qhov tseem ceeb rau kev tswj xyuas qhov siab ua haujlwm tsis tu ncua lossis ua kom cov khoom sib txawv ntawm lub tshuab ua kom zoo sib xws.
- Perpendicularity, los yog squareness, xyuas kom meej tias ob qhov chaw yog precisely 90 ° rau ib leeg. Nyob rau hauv ib tug raug Coordinate Measuring Machine (CMM), lub granite square kav, los yog lub hauv paus ntawm nws tus kheej, yuav tsum tau guaranteed perpendicularity kom tshem tawm Abbe yuam kev thiab lav tias X, Y, thiab Z axes yog tiag tiag orthogonal.
ZHHIMG Qhov txawv: Tshaj li Specification
Ntawm ZHHIMG, peb ntseeg tias qhov tseeb tsis tuaj yeem tshaj qhov tshwj xeeb - Kev lag luam precision tsis tuaj yeem xav tau dhau. Peb qhov kev cog lus mus dhau qhov ua tau raws li cov qauv ntsuas no. Los ntawm kev siv lub siab ceev ZHHIMG® Dub Granite (≈ 3100 kg / m³), peb cov platforms inherently muaj superior vibration damping thiab qis tshaj thermal expansion coefficient, ntxiv tiv thaiv cov ntawv pov thawj flatness, straightness, thiab parallelism los ntawm ib puag ncig thiab kev ua haujlwm cuam tshuam.
Thaum ntsuas qhov precision granite platform, saib tsis yog ntawm daim ntawv qhia tshwj xeeb nkaus xwb tab sis ntawm qhov chaw tsim khoom, cov ntawv pov thawj, thiab kev tswj xyuas qhov zoo-cov ntsiab lus uas ua rau ZHHIMG® tivthaiv qhov kev xaiv ruaj khov thiab txhim khu kev qha rau lub ntiaj teb kev thov ultra-precision daim ntaub ntawv.
