Kev tshuaj xyuas qhov zoo thiab qhov tsis zoo ntawm XYT precision active vibration isolation txav platform granite puag.

Ua ntej, qhov zoo ntawm granite puag
1. Kev ruaj khov thiab kev ruaj khov siab
Granite muaj qhov ceev siab (2.6-3.1g / cm³), thiab Young's modulus (elastic modulus) tuaj yeem ncav cuag 50-100 GPa, siab dua li cov hlau ib txwm (kwv yees li 200 GPa), tab sis vim nws cov qauv siv lead ua isotropic, nws yuav luag tsis muaj yas deformation hauv kev siv ntev. Piv nrog cov ntaub ntawv hlau, granite thermal expansion coefficient yog qis heev (kwv yees li 5 × 10⁻⁶ / ℃), nyob rau hauv qhov kub thiab txias hloov pauv ib puag ncig tseem tuaj yeem tswj tau qhov ruaj khov zoo heev, zam kev ntxhov siab txias vim thermal expansion cuam tshuam rau qhov tseeb ntawm cov khoom siv.

2. Kev ua haujlwm txo kev co zoo heev
Cov qauv siv lead ua sab hauv ntawm granite muaj kev cuam tshuam sab hauv siab, uas tuaj yeem nqus tau qhov kev co siab thiab txo qhov tshwm sim resonance. Piv nrog rau lub hauv paus hlau, granite muaj peev xwm ua kom lub zog co muaj zog dua hauv qhov ntau ntawm 20Hz-1kHz, muab qhov chaw "huv dua" rau qhov system cais kev co thiab txo qhov hnyav ntawm kev tswj hwm tom qab.

3. Kev tiv thaiv corrosion, tsis yog-sib nqus, dav siv tau
Granite tshuaj stability, acid thiab alkali corrosion tsis kam, yuav tsis xeb lossis oxidation, haum rau chav huv, av noo siab lossis corrosive ib puag ncig. Tsis tas li ntawd, granite yog cov khoom siv tsis muaj hlau nplaum, yuav tsis cuam tshuam nrog cov cuab yeej precision (xws li electron microscopy, magnetic ntsuas cov khoom siv, thiab lwm yam), haum rau cov xwm txheej thov electromagnetic rhiab heev.

4. Lub neej ntev kev pab cuam, tus nqi kho qis
Granite hardness siab (Mohs hardness 6-7), hnav tsis kam, siv ntev tsis yooj yim hnav lossis deformation, lub neej ua haujlwm tuaj yeem ncav cuag ntau dua 20 xyoo. Piv nrog cov ntaub ntawv hlau, nws tsis tas yuav tsum tau kho xeb lossis lubrication tas li, thiab cov nqi txij nkawm qis heev.

5. Siab tiaj tus thiab nto tiav
Los ntawm kev sib tsoo thiab polishing precision, qhov tiaj tiaj ntawm lub hauv paus granite tuaj yeem ncav cuag 0.005mm / m², thiab qhov roughness ntawm qhov chaw Ra≤0.2μm, ua kom ntseeg tau tias qhov haum zoo meej nrog cov khoom siv precision (xws li optical platform, laser interferometer) thiab txo cov kev ua yuam kev sib dhos.

Ob, qhov tsis zoo ntawm granite puag
1. Qhov hnyav loj, nyuaj rau nqa thiab teeb tsa
Granite muaj qhov ceev ceev thiab hnyav dua li txhuas lossis hlau ntawm tib qhov loj me, ua rau kev tuav thiab kev teeb tsa ntawm cov platform loj xav tau cov khoom siv tshwj xeeb (xws li forklifts lossis cov cuab yeej nqa khoom), ua rau cov nqi xa tawm nce ntxiv.

2. Kev tawg yooj yim, kev cuam tshuam tsis muaj zog
Txawm hais tias granite muaj qhov tawv heev, nws yog ib yam khoom tawg yooj yim thiab tej zaum yuav tawg lossis vau thaum raug kev cuam tshuam loj heev (xws li poob lossis sib tsoo). Yog li ntawd, yuav tsum tau ceev faj ntxiv thaum thauj mus los thiab teeb tsa kom tsis txhob muaj kev co lossis kev cuam tshuam loj heev.

3. Kev ua tiav nyuaj thiab tus nqi kho kom haum siab
Kev ua cov granite xav tau cov cuab yeej siv tshuab tshwj xeeb (xws li CNC pob zeb engraving tshuab) thiab cov cuab yeej pob zeb diamond, thiab qhov ceev ua tiav qeeb, ua rau tus nqi siab ntawm kev hloov kho cov qauv nyuaj (xws li cov qhov xov, cov grooves tshwj xeeb) thiab lub voj voog xa khoom ntev.

4. Kev hloov pauv kub tam sim ntawd yuav ua rau muaj cov kab nrib pleb me me
Txawm hais tias granite muaj kev ruaj khov zoo thermal, yog tias nws ntsib qhov kub hloov pauv ntau heev (xws li txav mus los ntawm qhov kub qis mus rau qhov kub siab), tej zaum yuav muaj qhov tawg me me hauv, thiab kev sib sau ua ke ntev yuav cuam tshuam rau lub zog ntawm cov qauv. Yog li ntawd, nws yuav tsum tau siv nrog kev ceev faj hauv cov chaw uas muaj qhov sib txawv ntawm qhov kub thiab txias loj.

5. Tsis muaj vuam lossis ua tiav theem ob
Lub hauv paus hlau tuaj yeem hloov kho los ntawm kev vuam lossis kev ua haujlwm, tab sis thaum cov granite raug tsim, nws yuav luag tsis yooj yim sua kom hloov kho cov qauv (xws li kev khawb, txiav), yog li theem tsim yuav tsum tau npaj kom meej kom tsis txhob muaj kev hloov kho tom qab.
