Hauv kev ua haujlwm siab - huab cua ceev - bearing linear motion platforms, optical scanning platforms and wafer inspection air - bearing worktables, the comprehensive performance of the substrate directly txiav txim siab khiav smoothness ntawm huab cua bearings, motion repeatability thiab ntev -lub sij hawm kev pab cuam stability. Ntau cov khoom lag luam sib piv aluminium alloy, cam khwb cia hlau, ceramics thiab ntau yam ntaub ntawv pob zeb dua, thiab feem ntau ntawm lawv thaum kawg xaiv siab - ntom dub granite ua lub ntsiab substrate rau huab cua bearing platforms. Nws yog dav paub tias granite muab kev co zoo heev damping kev ua tau zoo. Txawm li cas los xij, ob peb tus neeg paub tias dub granite muaj ntau lub zog tseem ceeb uas tsis tuaj yeem rov ua dua los ntawm lwm cov ntaub ntawv raws li kev ua haujlwm tshwj xeeb ntawm huab cua bearing systems. UNPARALLELED tau ntev tshwj xeeb hauv customized ultra-precision granite Cheebtsam, muab lub hauv paus ncej, kab teeb thiab worktables rau huab cua bearing khoom manufacturers thoob ntiaj teb. Kev kos duab ntawm kev paub txog kev ua haujlwm ntau, peb txheeb xyuas tus nqi tshwj xeeb ntawm dub granite rau huab cua bearing platforms.
Cov kab hluav taws xob hauv huab cua paub tias tsis yog -kev sib cuag txav los ntawm ib txheej nyias ntawm siab - cov pa roj. Me me substrate deformation, nto micro-undulations thiab thermal deformation yuav ncaj qha ua rau slider jitter thiab huab cua hloov pauv. Aluminium alloy yog lub teeb yuag tsis tau muaj qhov sib txawv ntawm thermal expansion coefficient, ua rau lub platform nquag deformation nyob rau hauv ambient kub hloov. Cam khwb cia hlau boasts zoo rigidity, tab sis raug kev txom nyem los ntawm corrosion thaum lub sij hawm ntev - kev pab cuam, ntau tus kheej - nyhav thiab txwv damping peev. Ceramics pom zoo thermal stability, tsis tau loj -size monolithic forming yog nyuaj nrog siab machining nqi. Lub teeb zoo tib yam- xim granite muaj qhov sib npaug ntawm cov ntxhia hauv cov ntxhia thiab cov porosity ntau dua, ua rau muaj kev sib khi tsis txaus tom qab ua tiav, uas ua rau nws tsis tsim nyog rau cov pa roj txuas ntxiv ntawm cov qauv huab cua. Nyob rau hauv sib piv, UNPARALLELED® dub granite nta densely thiab uniformly teem crystals nrog tsis tshua muaj porosity. Tom qab ultra-precision lapping, lub platform nto ua tau zoo dua nruj, tswj cov huab cua zoo ib yam tsis tu ncua, tiv thaiv cov dej hauv zos ntawm siab - siab roj thiab ua kom ruaj khov ua haujlwm ntawm huab cua bearings.
Vibration suppression yog ib qho tseem ceeb qhia tau rau huab cua bearing platforms. Siab -Kev nrawm nrawm thiab kev cuam tshuam ntawm kev cob qhia sab nraud ua rau muaj kev vibration. Thaum kev co xa mus rau saum huab cua- bearing worktable, nws yuav destabilize lub ultra-thin air film, degrade positioning raug thiab qhov muag plooj pom. Kev vibration decays maj mam thiab kav ntev dua nyob rau hauv cov khoom siv hlau. Los ntawm kev sib piv, dub granite muaj qhov muaj zog damping zog; Lub zog vibration tuaj yeem nqus tau sai los ntawm cov khoom siv lead ua sab hauv ntawm lub pob zeb, ua rau txo qis kev pheej hmoo ntawm resonance. Tshwj xeeb tshaj yog rau ntev - mus txawv tebchaws siab - ceev huab cua bearing platforms, cuam tshuam kev co generated thaum lub sij hawm pib thiab nres yuav sai sai attenuated los ntawm granite substrate kom cov lus tsa suab kawg ruaj khov txhua lub sij hawm. Qhov no yog qhov laj thawj tseem ceeb vim li cas cov granite dub yog qhov tseem ceeb rau cov huab cua bearing platforms xa mus rau hauv siab -precision optical soj ntsuam thiab semiconductor metrology khoom.
Dimensional thermal stability txiav txim siab lub peev xwm ntawm cov khoom siv huab cua rau puag ncig - lub - moos ua haujlwm tas mus li. Cov kev cob qhia muaj kev hloov pauv me ntsis ntawm qhov kub thiab txias, thiab cov khoom siv txuas ntxiv ua haujlwm kuj ua rau muaj cua sov me ntsis. Dub granite muaj ib qho ultra- qis thermal expansion coefficient, thiab nws thermal expansion thiab contraction nyob rau hauv qhov kub thiab txias variation yog deb me ntsis dua li cov ntaub ntawv hlau. Cua bearing platforms muaj precision micropores, cua muab grooves thiab positioning reference nto. Txhua qhov hloov maj mam deformation yuav hloov pauv huab cua sib txawv. Kev siv cov xim dub granite substrates txo qis cua cov yeeb yaj kiab thickness variation tshwm sim los ntawm thermal drift, txo qhov tseeb offset tom qab siv cov cuab yeej siv ntev thiab txiav ntau zaus calibration, yoog mus rau 24- teev tsis nres loj soj ntsuam hauv factories.
Cua bearing platforms feem ntau cia cov cua grooves, threaded mounting qhov thiab lub tshuab nqus tsev adsorption zones, imposing nruj kev cai ntawm machinability thiab structural stability ntawm substrates. Premium dub granite nta nruab nrab hardness thiab homogeneous zoo nkauj. Nws txhawb txoj kev machining xws li grooving, drilling thiab hollowing, thiab tiv thaiv kev ntxhov siab hauv zos thiab tawg tom qab ua tiav. Tsis tas li ntawd, cov khoom siv yog oxidation- tiv taus thiab tsis hnov tsw rau cov av noo, tshem tawm qhov xav tau rau cov txheej txheem tiv thaiv ntxiv thiab tshem tawm qhov kev pheej hmoo ntawm cov kab mob hauv huab cua uas tshwm sim los ntawm txheej txheej txheej. Ntau cov cuab yeej siv huab cua tau muab tso rau hauv chav huv. Dub granite tuav ruaj khov physicochemical zog thiab yuav tsis tso cov pa paug, ua raws cov plua plav-dawb cov qauv tsim nyob rau hauv semiconductor thiab optoelectronic industries.
Monolithic txoj kev ntxiv txhim kho daim ntawv thov nqi ntawm dub granite. Loj ntev -mus ncig huab cua bearing beams thiab ntxiv- loj square air bearing worktables tuaj yeem ua tiav los ntawm ib lub pob zeb dawb paug kom ua tiav seamless monolithic qauv. Spliced structures inevitably muaj qhov sib txawv ntawm qhov sib txawv uas yooj yim ua rau cov pa tawm. Tsis tas li ntawd, qhov tsis sib xws ntawm cov pob qij txha ua rau qhov tsis sib xws ntawm kev deformation nyob rau hauv lub sijhawm ntev - loads. Monolithic dub granite Cheebtsam zam cov teeb meem saum toj no nrog kev sib npaug tag nrho rigidity thiab kev sib koom ua ke siv precision. Kev txhawb nqa los ntawm Chav Kawm 10,000 qhov tsis tu ncua- qhov kub ntawm cov av noo huv rhiav, peb ua ultra-precision lapping thiab ntau-dimensional raug kuaj xyuas kom ntseeg tau tias qhov flatness thiab waviness ntawm worktables ua tau raws li cov lus qhia tshwj xeeb uas xav tau rau kev ua haujlwm huab cua.
Tsis muaj ib qho khoom siv tuaj yeem haum rau txhua yam kev ua haujlwm. Txawm li cas los xij, rau cov huab cua bearing motion platforms yuav tsum tau sub-micron thiab nanometer precision, dub granite integrates ntau yam yam ntxwv xws li tsis tshua muaj expansion, siab damping, tsis muaj porosity, ruaj khov physicochemical kev ua tau zoo thiab muaj peev xwm rau loj -scale monolithic machining, xa irreplaceable comprehensive zoo. UNPARALLELED tsis tu ncua optimizes machining technology rau dub granite. Peb tsim tshwj xeeb ua cov kev daws teeb meem tsom rau huab cua grooves, sealing nto thiab mounting references ntawm huab cua bearing platforms, thiab muab ntev -lub sij hawm ruaj khov granite siv tivthaiv kev daws teeb meem rau siab - kawg huab cua bearing motion platforms.
