Raws li laser txiav tshuab thawb mus rau hauv lub realm ntawm femtosecond thiab picosecond lasers, qhov xav tau ntawm cov cuab yeej kho tshuab stability tau dhau los. Lub rooj ua haujlwm, lossis lub hauv paus tshuab, tsis yog kev txhawb nqa xwb; nws yog lub ntsiab txhais ntawm qhov system raug. ZHONGHUI Group (ZHHIMG®) tshuaj xyuas cov laj thawj tseem ceeb vim li cas cov granite high-density tau dhau los ua qhov kev xaiv zoo tshaj plaws, tsis muaj kev sib tham ntawm cov khoom siv hlau ib txwm siv rau kev ua haujlwm siab laser txiav worktables.
1. Thermal Stability: Defeating lub tshav kub sib tw
Laser txiav, los ntawm nws qhov xwm txheej, ua kom sov. Hlau worktables - feem ntau yog hlau los yog cam khwb cia hlau - raug kev txom nyem los ntawm ib tug siab coefficient ntawm thermal expansion (CTE). Raws li qhov kub thiab txias hloov pauv, cov hlau nthuav dav thiab sib cog lus ntau, ua rau micron-theem seem hloov pauv thoob plaws lub rooj saum npoo. Qhov no thermal drift ncaj qha txhais mus rau txoj kev txiav tsis raug, tshwj xeeb tshaj yog nyob rau lub sijhawm ntev lossis hauv cov tshuab loj.
Hauv qhov sib piv, ZHHIMG®'s Black Granite khav theeb CTE qis heev. Cov khoom yog inherently resistant rau kub hloov, kom ntseeg tau hais tias qhov tseem ceeb geometric qhov ntev ntawm lub worktable nyob ruaj khov txawm tias thaum lub sij hawm khaus, ntev ua hauj lwm. Qhov thermal inertia no tseem ceeb heev rau kev tswj cov nanometer-theem precision xav tau los ntawm niaj hnub laser optics.
2. Vibration Damping: Ua tiav Beam Control
Laser txiav, tshwj xeeb tshaj yog high-speed los yog mem tes laser tshuab, generates dynamic rog thiab vibrations. Hlau resonates, amplifying cov kev vibrations thiab ua rau me jitters nyob rau hauv lub system, uas yuav plam lub laser qhov chaw thiab degrade txiav zoo.
Cov qauv ntawm ZHHIMG®'s high-density granite (txog ≈3100 kg / m3) yog qhov tsim nyog rau kev co zoo dua. Granite ib txwm absorbs mechanical zog thiab dissipates nws sai. Lub hauv paus nyob ntsiag to, ruaj khov no ua kom ntseeg tau tias lub ntsej muag zoo nkauj laser tsom optics thiab high-speed linear motors ua haujlwm nyob rau hauv ib puag ncig tsis muaj kev vibration, tswj xyuas qhov tseeb ntawm qhov chaw ntawm beam thiab kev ncaj ncees ntawm kev txiav ntug.
3. Cov khoom siv ruaj khov: Tsis-Corrosive thiab Tsis-Magnetic
Tsis zoo li cov hlau, granite yog non-corrosive. Nws muaj kev tiv thaiv rau cov coolants, txiav kua, thiab atmospheric humidity ib puag ncig nyob rau hauv manufacturing ib puag ncig, kom lub worktable lub neej ntev thiab geometric kev ncaj ncees nyob twj ywm tsis muaj kev pheej hmoo ntawm xeb los yog cov khoom degradation.
Tsis tas li ntawd, rau cov khoom siv sib xyaw ua ke zoo sib nqus rhiab heev los yog linear motor technology, granite yog non-magnetic. Qhov no tshem tawm qhov kev pheej hmoo ntawm kev cuam tshuam ntawm electromagnetic cuam tshuam (EMI) uas cov hlau hauv paus tuaj yeem qhia tau, tso cai rau cov txheej txheem kev ua haujlwm zoo ua haujlwm tsis zoo.
4. Muaj peev xwm ua tau: Tsim kom muaj qhov loj thiab meej
ZHHIMG® lub peev xwm tsim khoom tsis sib xws tshem tawm cov kev txwv loj uas feem ntau plague hlau-raws li rooj. Peb tshwj xeeb hauv kev tsim ib qho monolithic granite rooj txog li 20 meters ntev thiab 100 tons hauv qhov hnyav, polished rau nanometer flatness los ntawm peb cov kws ua haujlwm master. Qhov no tso cai rau cov neeg tsim lub tshuab laser los tsim super-loj hom cutters uas tswj ib qho kev ncaj ncees thiab ultra-precision thoob plaws lawv lub hnab ntawv ua hauj lwm tag nrho - ib qho kev ua tsis tau zoo nrog cov welded lossis bolted hlau sib dhos.
Rau cov tuam txhab lag luam ntawm lub ntiaj teb-chav laser txiav tshuab, kev xaiv yog qhov tseeb: qhov tsis sib xws ntawm thermal stability, kev co damping, thiab monolithic precision ntawm ZHHIMG® Granite Worktable muab lub hauv paus kawg rau kev ceev thiab raug, tig micron-theem kev cov nyom rau hauv cov txiaj ntsig niaj hnub.
