Hauv kev nrhiav kev raug ntawm sub-micron, lub ntiaj teb kev lag luam tau tsiv tawm ntawm qhov xwm txheej volatile ntawm cov hlau cam khwb cia thiab mus rau qhov ruaj khov ntawm granite. Txawm li cas los xij, raws li qhov yuav tsum tau ua kom raug dua hauv cov khoom siv semiconductor, laser, thiab aerospace, kev nkag siab txog kev siv granite yog qhov tseem ceeb dua puas tau. Ntawm ZHHIMG, peb pom tias ntau tus engineers sib ntaus nrog ob qhov kev txiav txim siab tseem ceeb: sib txawv ntawm lub phaj nto thiab lub hauv paus granite, thiab xaiv cov khoom siv mineral kom raug - tshwj xeeb tshaj yog kev sib cav ntawm Black thiab Pink granite.
Kev Ncaj Ncees ntawm Cov Qauv: Sib piv Granite Base thiab Surface Plate
Ib qho kev pom tseeb, ib lub phaj granite nto thiab ibgranite tshuab puagtej zaum yuav zoo ib yam. Ob leeg puav leej hnyav, tsaus ntuj nti, thiab tiaj tus heev. Txawm li cas los xij, lawv lub hom phiaj kev tsim kho thiab cov qauv thauj khoom sib txawv heev.
Ib lub phaj granite nto yog tsim los ua lub dav hlau passive reference. Nws lub luag haujlwm tseem ceeb yog los muab ib qho "tiag tiag tiaj tus" nto rau cov cuab yeej tshuaj xyuas thiab kev ntsuas tes. Qhov kev kam rau siab yog tswj hwm los ntawm qhov saum npoo ib leeg. Hauv kev sib piv, lub hauv paus tshuab granite yog ib qho khoom siv ua haujlwm. Nws ua haujlwm ua lub chassis rau high-speed CNCs, Coordinate Measuring Machines (CMMs), lossis cov khoom siv lithography.
Kev tsim kho ntawm lub hauv paus granite muaj kev xav txog sab hauv uas nyuaj heev uas lub phaj saum npoo tsis tshua muaj. Cov hauv paus no feem ntau muaj cov kav dej tob rau kev txuas hluav taws xob, cov lus qhia meej rau cov kabmob cua, thiab cov ntxig hlau tsis xeb uas yuav tsum tiv taus cov khoom thauj hnyav. Thaum lub phaj saum npoo ntsuas los ntawm nws qhov tiaj tiaj hla lub dav hlau, lub hauv paus granite yuav tsum tau soj ntsuam rau nws qhov sib piv ntawm qhov tawv thiab qhov hnyav thiab nws lub peev xwm los tswj kev sib dhos geometric hauv qab qhov hnyav ntawm cov gantries thiab spindles txav mus los.
Kev Tshawb Fawb Txog Xim: Granite Dub vs. Granite Liab
Ib qho ntawm cov lus nug txog kev siv tshuab uas peb tau txais ntau tshaj plaws yog qhov sib txawv ntawm cov mineralogical ntawm cov granite dub thiab liab. Txawm hais tias muaj kev nyiam zoo nkauj, qhov kev xaiv raucov khoom siv tshuab precisionyog tsav los ntawm physics nruj me ntsis.
Cov granite dub, xws li Jinan Black uas ZHHIMG siv, yog technically ib tug gabbro lossis diabase. Nws yog tus cwj pwm los ntawm nws qhov ceev ceev thiab cov qauv crystalline zoo heev. Los ntawm qhov kev xav ntawm metrology, cov granite dub zoo dua vim nws qhov kev nqus dej qis dua thiab cov modulus ntawm elasticity siab dua. Qhov ceev no txhais tau ncaj qha mus rau hauv qhov ruaj khov ntau dua; nws tsis tshua muaj peev xwm "ua pa" lossis warp thaum cov av noo hloov pauv hauv ib qho chaw.
Qhov sib txawv, granite liab feem ntau muaj feem pua ntawm quartz thiab cov noob loj potash feldspar. Thaum granite liab yog qhov nyuaj heev - qee zaum nyuaj dua li granite dub - nws kuj tseem yooj yim dua thiab yooj yim "flaking" ntawm cov ciam teb crystalline. Qhov loj me ntawm cov noob loj dua tuaj yeem ua rau nws nyuaj dua los ua tiav qhov tiav zoo li daim iav uas xav tau rau cov chaw uas muaj huab cua.
Tsis tas li ntawd xwb, feem ntau cov granite dub muaj cov coefficient siab dua ntawm kev co damping. Hauv kev siv tshuab ceev ceev, lub peev xwm ntawm lub hauv paus los nqus cov zaus harmonic yog qhov sib txawv ntawm qhov tsis lees paub thiab qhov tiav zoo meej. Rau feem ntau cov khoom siv tshuab siab, cov granite dub tseem yog qhov ntsuas kev lag luam rau kev ruaj khov thiab lub neej ntev.
Cov Ncauj Lus Qib Siab hauv Cov Cheebtsam Tshuab Ua Ntej
Thaum peb txav mus dhau cov khoom siv nws tus kheej, qhov kev tsom mus rau kev sib koom ua ke ntawm granite rau hauv lub tshuab tsim kinematic. Cov khoom siv precision niaj hnub no tsis yog cov thaiv static lawm; lawv yog cov khoom sib xyaw ua ke.
Ib qho ntawm cov qauv kev lag luam uas tab tom loj hlob sai hauv kev lag luam yog kev koom ua ke ntawm granite nrog lub tshuab nqus tsev. Los ntawmkev ua haujlwm raugCov kav dej nqus tsev ncaj qha mus rau hauv lub hauv paus granite, cov chaw tsim khoom tuaj yeem tsim cov nplaim "vacuum chuck" rau kev tuav wafer hauv kev lag luam semiconductor. Qhov no tsis yog tsuas yog xav tau qhov tiaj tiaj xwb tab sis kuj yog cov khoom siv uas tsis muaj porosity, qhov twg granite dub zoo tshaj plaws.
Lwm yam tseem ceeb yog kev them nyiaj thermal. Txawm hais tias granite muaj cov coefficient qis ntawm thermal expansion, nws tsis yog xoom. Cov khoom siv tshuab niaj hnub no feem ntau suav nrog cov sensors thermal uas muab tso rau hauv pob zeb. Vim tias granite muaj cov thermal mass siab, nws qeeb qeeb teb rau qhov kub thiab txias hloov pauv, muab cov nyhuv "thermal flywheel" uas tiv thaiv lub tshuab los ntawm kev kub ntxhov ib puag ncig sai.
Txoj Kev ZHHIMG rau Kev Tsim Kho Vaj Tse
Ntawm ZHHIMG, peb lees paub tias txhua qhov khoom siv precision qhia ib zaj dab neeg ntawm ib qho kev sib tw engineering tshwj xeeb. Peb cov txheej txheem tsim khoom pib nrog kev xaiv cov pob zeb raw, kom ntseeg tau tias qhov kev faib tawm quartz yog sib xws los tiv thaiv kev ntxhov siab sab hauv.
Peb cov khoom siv tshuab ua kom raug raws li qhov yuav tsum tau ua kom raug yuav dhau los ntawm kev ua kom lub pob zeb ruaj khov tom qab pib ua haujlwm tsis zoo, peb xyuas kom meej tias qhov kev sib tsoo zaum kawg—ua los ntawm peb cov kws tshaj lij—ua rau qhov chaw uas yuav tsis "nkag mus" dhau kaum xyoo tom ntej ntawm kev siv. Txawm hais tias nws yog lub gantry ntau tuj rau lub tshuab txiav laser lossis lub hauv paus me me rau lub tshuab kuaj mob hauv chaw kuaj mob, cov ntsiab cai ntawm kev ruaj khov geological tseem zoo ib yam.
Xaus Lus: Yav Tom Ntej ntawm Cov Hauv Paus Mineral
Raws li lub sijhawm "Kev Lag Luam 4.0" xav tau kev nrawm dua thiab kev kam rau siab dua, lub luag haujlwm ntawm granite txuas ntxiv hloov pauv. Peb pom kev txav mus rau granite-epoxy composites rau qee qhov kev siv ntau, tab sis rau qhov siab tshaj plaws ntawm kev ruaj khov, granite dub ntuj tseem tsis tau muaj leej twg sib tw.
Kev xaiv lub hauv paus zoo yog thawj kauj ruam hauv txhua qhov project precision. Los ntawm kev nkag siab txog qhov sib txawv ntawm lub phaj yooj yim thiab lub hauv paus qauv, thiab los ntawm kev xaiv qhov ceev ntawm cov granite dub, cov engineers xyuas kom meej tias lawv cov kev tsim kho tshiab tau tsim rau ntawm lub hauv paus uas yuav sawv qhov kev xeem ntawm lub sijhawm thiab qhov kub.
