Nyob rau hauv loj-mus ncig gantry-type ultra-precision khoom systems, granite txuas hniav, tseem hu ua granite crossbeams, sawv cev rau qhov tseem ceeb tshaj plaws transverse load-bearing Cheebtsam nyob rau hauv lub motion ncej. Tsis zoo li zoo tib yam granite saum npoo daim hlau feem ntau yog siv rau cov ntaub ntawv metrological zoo li qub, granite txuas hniav yog cov qauv kev nyuab siab dynamically. Lawv yuav tsum ua kom tau raws li qhov yuav tsum tau ua loj thaum thauj khoom xws li cov rooj zawv zawg, cov khoom siv huab cua, lub taub hau tshuaj xyuas qhov muag thiab cov tshuab ua haujlwm, thiab tsis tu ncua tiv thaiv inertial shocks los ntawm reciprocating motion. Thaum xaiv qhov project, ntau tus neeg yuav khoom tsuas yog tsom mus rau qhov ntu ntu qhov ntev, qhov hnyav thiab qhov ntsuas qhov tsis sib xws, tsis quav ntsej qhov kev ua haujlwm ntawm qhov sib txawv ntawm daim ntawv thov scenarios. Qhov no ua rau cov khoom lag luam tsis sib haum xeeb tawm tsam cov kev xav tau, ua rau muaj teeb meem ntawm qhov chaw xws li kev ua haujlwm jitter, thermal deformation thiab kev sib dhos kev ntxhov siab. Kev nkag siab tag nrho ntawm granite-bridge daim ntawv thov cov yam ntxwv nyob rau hauv cov xwm txheej sib txawv ua rau cov khoom zoo ntawm cov khoom siv pob zeb kom tau txais txiaj ntsig zoo.
Cov khoom siv semiconductor tsim ib daim ntawv thov rau cov choj granite. Raws li cov txheej txheem tsim cov chips ua rau kev nce qib, kev tshuaj xyuas, raug thiab txheej txheej cov cuab yeej ua rau cov kev xav tau nruj ntawm cov lus tsa suab. Nyob rau hauv cov xwm txheej zoo li no, nruab nrab-rau-ntev-ntev-ntev granite txuas hniav feem ntau nqa huab cua-cov kabmob zawv zawg rooj kom paub txog kev siv ceev ceev qis-jitter scanning. Tus cwj pwm los ntawm kev txav mus los tsis tu ncua, kev tsim hluav taws xob tas mus li los ntawm cov khoom siv sab hauv tsim qhov kub thiab txias gradients. Tau txais txiaj ntsig los ntawm nws cov cuab yeej thermal-expansion tsawg, granite txo qis beam dabtsi yog khoov deformation vim qhov kub hloov pauv. Tshaj li cov khoom ua tau zoo, cov qauv siab heev yog tsim los ntawm mating-lapping zoo ntawm kev sib koom ua ke ntawm qhov chaw thiab tag nrho torsion tswj rau granite txuas hniav. Me me torsion ntawm crossbeam yuav ncaj qha distort cov duab soj ntsuam thiab ua rau cov qauv paub yuam kev. Lub caij no, kev cob qhia semiconductor xav tau kev huv huv siab, yog li kev kho tshwj xeeb saum npoo yog siv rau cov txuas hniav granite kom txo cov khoom me me thiab hloov mus rau qhov chaw ua haujlwm huv.
Laser precision-machining daim ntaub ntawv teev tshwj xeeb yuav tsum tau rau load compatibility thiab dynamic teb ntawm granite choj. Femtosecond thiab picosecond laser cov cuab yeej ua haujlwm micro-txiav, micro-qhov drilling thiab hloov khoom siv, nrog lub taub hau laser thiab kho qhov muag sib dhos mounted rau saum crossbeams. Instant thermal tawg thiab machining khib nyiab yog generated thaum lub sij hawm laser ua. Txawm hais tias lawv yuav tsis hlawv lub cev nqaj ncaj qha, cov khib nyiab khib nyiab tuaj yeem ua rau cov mating. Rau cov choj granite hauv qhov xwm txheej no, qhov sib npaug ntawm qhov sib npaug, qhov hnyav ntawm tus kheej thiab kev nruj yuav tsum ua tiav. Cov kab hluav taws xob ntau dhau ntawm tus kheej qhov hnyav nce lub nra ntawm cov kab gantry thiab tsav tsheb; over-hollowing rau qhov hnyav txo kev txi tag nrho nruj thiab ua rau cov qauv resonance nyob rau hauv high-speed motion. Yog li ntawd, cov qauv kev simulation ua ke nrog qhov siab tshaj plaws acceleration thiab load hnyav yuav tsum tau nyob rau hauv lub sij hawm kev daws teeb meem los txiav txim siab rational cross-section forms. Qhov loj dua tsis yog txhais tau tias qhov tuab dua thiab qhov dav dav dua ib txwm zoo dua.
Loj-loj metrology soj ntsuam cov cuab yeej yog lwm qhov tseem ceeb daim ntawv thov teb rau granite txuas hniav, sawv cev los ntawm loj gantry-type CMMs, profile scanners thiab cov lus qhia loj loj-ntsia hlau ntsuas ntsuas. Es tsis txhob mus nrhiav ultra-siab txav ceev, cov khoom siv no qhia txog qhov tseeb ntawm qhov tseeb-dynamic sib xyaw ua haujlwm ntev. Granite txuas hniav ua raws li cov neeg nqa khoom rau kev soj ntsuam cov tshuab; Cov txheej txheem ntsuas yuav kav ntev li ib teev, thiab qhov cuam tshuam me me ntawm qhov chaw nyob ib puag ncig yuav sib sau ua qhov ntsuas qhov yuam kev. Tus nqi tseem ceeb ntawm granite txuas hniav hauv metrology yog nyob rau hauv kev xa cov ntaub ntawv geometric ruaj khov thiab tsis sib xws. High rigidity thiab damping zog ntawm granite tsis av vibration thiab kub-humidity fluctuations nyob rau hauv kev cob qhia. Sib txawv ntawm cov khoom siv semiconductor thiab laser, granite txuas hniav rau cov khoom siv metrology feem ntau yog pre-machined nrog ntau threaded mounting qhov thiab nrhiav tus pin qhov rau kev txhim kho ntau yam sensors thiab scale assemblies. Qhov tseeb qhov tseeb ntawm qhov thiab kev tswj hwm sab hauv ntawm threaded qhov tsis ncaj qha cuam tshuam qhov sib xws ntawm cov ntaub ntawv ntsuas tom ntej.
Granite txuas hniav siv hauv PCB thiab cov khoom siv vaj huam sib luag zoo li mus rau qhov loj ntxiv. Kev tshuaj xyuas vaj huam sib luag thiab PCB drilling tshuab yuav tsum tau npog qhov ntev ntawm lub workpiece, uas thawb crossbeam ncua kev loj hlob tsis tu ncua. Qhov kev sib tw tseem ceeb rau qhov loj-span granite txuas hniav yog los ntawm tus kheej qhov hnyav deflection. Txawm hais tias zoo heev granite rigidity, loj span yuav inevitably nqa me ntsis downward dabtsi yog khoov los ntawm tus kheej-qhov hnyav. Xws li tus kheej qhov hnyav deflection yog lub hom phiaj lub cev tshwm sim uas tsis tuaj yeem tshem tawm tag nrho; nws tsuas tuaj yeem tswj hwm los ntawm kev ua kom zoo ntawm cov qauv, mounting schemes thiab pre-compensation tsim. Ib qho kev xav tsis zoo xav kom cov khoom siv pob zeb ib leeg tshem tawm deflection. Yog tias tsis muaj kev them nyiaj ua ntej, cov cuab yeej tswj xyuas qhov raug tsim nyog nyob rau hauv qhov tsis muaj kev thauj khoom tsis tau muaj kev cuam tshuam ntawm crossbeam deformation ib zaug loaded, ua rau tag nrho cov khoom raug hloov pauv. Yog li nws tus kheej qhov hnyav deflection thiab load-induced deflection yuav tsum tau soj ntsuam ua ntej rau kev siv loj.
Cov cuab yeej tsim kho kev cai rau cov tsev kawm qib siab thiab cov tsev kawm metrology nthuav qhia ntau hom kev ua haujlwm rau cov choj granite. Qee qhov kev sim teeb tsa xav tau kev sib raug zoo nrog qhov chaw kub qis, qhov chaw sov hauv zos thiab kev sib koom ua ke ntau yam. Sib nrug los ntawm cov qauv geometric raug, cov kev xav tau tshwj xeeb raug tsa rau kev hloov kho mounting interfaces, tsis tu ncua kev txiav tawm thiab cov qauv hnyav. Fast iteration cycles nyob rau hauv kev tshawb fawb tshawb fawb feem ntau xav tau cov khoom refitting thiab tivthaiv reconfiguration. Granite txuas hniav yuav tsum cia expansion interfaces nyob rau theem tsim. Meanwhile, rigidity degradation tshwm sim los ntawm ntau lub qhov thiab qhov yuav tsum tau soj ntsuam kom tsis txhob deteriorated structural kev ua tau zoo.
Granite txuas hniav tsis yog universal txheem qhov chaw, thiab tsis muaj ib txheej ntawm tsis haum rau tag nrho cov scenarios. Cov ntawv thov semiconductor tseem ceeb tshaj qhov tsis tshua muaj suab nrov thiab huv chav hloov kho; laser-processing units tsom rau rigidity-rau-hnyav tshuav nyiaj li cas; cov cuab yeej siv ntsuas ntsuas ua rau lub sijhawm ntev siv kev ruaj ntseg hauv thawj qhov chaw; PCB thiab vaj huam sib luag li hais txog deflection tswj rau loj spans; Cov cuab yeej tshawb fawb-kev tshawb fawb xav tau kev hloov kho interfaces thiab cov txheej txheem redundancy. Dhau li ntawm cov khoom siv raw zoo, kev tsim qauv tsim qauv, sib koom ua ke-nto craftsmanship, qhov machining, deflection pre-compensation thiab kev kho deg sib sau ua ke txiav txim siab txog kev ua tau zoo hauv ntiaj teb.
Thaum lub sij hawm ua qhov project, load magnitude, motion acceleration, operating-temperature range, span requirements and ambient interferences yuav tsum tau qhia meej ua ntej ua ntej txhais cov qauv thiab cov txheej txheem rau granite txuas hniav. Customized matching tiv thaiv cov kev ua haujlwm tiag tiag tso cai rau cov txuas hniav granite kom ua kom cov khoom zoo tshaj plaws, zam cov kev pheej hmoo ntawm daim ntawv thov thiab xa cov kev txhim khu kev qha transverse load-bearing foundation rau ntau yam khoom siv ultra-precision gantry.
