Vim li cas ho xaiv Granite Air Bearings rau Zero-Friction Precision Movement?

Cov kabmob cua granite xa cov kev txav mus los xoom-kev sib txhuam tseem ceeb rau kev ua haujlwm sub-micron hauv kev tshuaj xyuas semiconductor, CMM, thiab cov tshuab metrology optical. Tsis zoo li cov hlau lossis cov khoom siv ceramic, cov granite ceev ceev (≈3100kg / m³) muab kev ruaj khov thermal zoo dua (<0.001mm / ° C), kev ntub dej ntuj, thiab kev ruaj khov ntev. ZHHIMG® tsim cov kabmob cua granite txog li 20,000mm nrog kev tswj hwm kev kam rau siab ISO-qib, pabcuam cov chaw tsim khoom siv precision thoob ntiaj teb.

Cov Bearings Cua Yog Dab Tsi Thiab Lawv Ua Haujlwm Li Cas?

Cov kabmob cua—tseem hu ua aerostatic bearings—txhawb cov khoom thauj ntawm ib daim nyias nyias ntawm cov cua compressed es tsis yog cov khoom sib cuag khov kho. Cov cua uas muaj siab ntws los ntawm cov qhov nkag mus rau hauv qhov sib txawv ntawm cov kabmob, tsim cov zaj duab xis cua uas yuav luag tsis muaj zog feem ntau yog li ntawm 5 txog 20 micrometers.

Tus qauv tsim no tshem tawm kev sib txhuam ntawm cov khoom siv tag nrho, tshem tawm kev sib txhuam ntawm cov khoom siv, cov khib nyiab hnav, thiab cov chaw co uas ua rau cov kabmob dov lossis swb puas tsuaj. Qhov tshwm sim: kev txav du thiab tsis muaj kev cuam tshuam uas ua tau ntawm qhov tseeb ntawm qib nanometer.

Rau kev siv semiconductor wafer, cov tshuab ntsuas sib koom ua ke (CMM), thiab AOI (automated optical inspection), qhov kev sib txhuam xoom no tsis yog xaiv tau - nws yog qhov yuav tsum tau ua ua ntej rau kev xa tawm thiab cov lus qhia txog cov khoom tawm.

Vim li cas Granite thiaj yog cov khoom siv zoo tshaj plaws rau kev tsim kho cua?

1. Kev Ruaj Ntseg Thermal Zoo Tshaj Plaws

Granite muaj cov coefficient ntawm thermal expansion ntawm kwv yees li 8 × 10⁻⁶ / ° C, txhais tau tias qhov kev hloov pauv ntawm qhov ntev hauv qab 0.001 hli ib degree Celsius. Piv txwv li, hlau nthuav dav kwv yees li 12 × 10⁻⁶ / ° C.

Hauv cov chaw ua haujlwm semiconductor qhov twg qhov kub thiab txias ib puag ncig raug tswj hwm nruj (feem ntau ± 0.5 ° C), qhov kev ruaj khov no ua kom ntseeg tau tias cov txheej txheem ntsuas tswj hwm kev kho kom raug thoob plaws kev hloov pauv thiab kev khiav ua ke. ZHHIMG® dub granite, nrog nws cov qauv crystalline ntom ntom (qhov ceev ≈3100kg / m³), ​​muab cov cua sov uas tiv taus qhov kub hloov pauv sai.

2. Kev co zoo tshaj plaws

Cov qauv me me ntawm Granite nqus tau lub zog co zoo dua li hlau. Hlau co nrog qhov tsis tshua muaj kev co - lub zog rov qab los thoob plaws hauv cov qauv. Granite ua rau kev co qis dua sab hauv, txo qhov kev sib haum xeeb hauv kev luam theej ceev thiab cov txheej txheem kauj ruam thiab rov ua dua.

Rau cov tshuab tshuaj xyuas qhov muag uas ua haujlwm ntawm kHz-level frame rates, qhov damping no txhais ncaj qha mus rau hauv kev txo cov duab tsis meej thiab sai dua, txhim khu kev qha dua kev kuaj pom qhov tsis zoo.

3. Kev Tiv Thaiv Kev Xeb thiab Kev Ua Neej Ntev

Cov khoom siv granite uas raug ua kom raug yuav tiv taus xeb los ntawm cov dej txias, cov tshuaj ntxuav, thiab cov dej noo hauv huab cua. Cov kabmob hlau xav tau cov txheej tiv thaiv (chrome, nickel, lossis ceramic plating) uas tuaj yeem lwj mus raws sijhawm. Cov qauv pob zeb hauv granite tseem tsis muaj zog, khaws cia qhov chaw tiaj tus thiab raug rau ntau xyoo ntawm lub neej kev pabcuam.

4. Kev Ruaj Ntseg ntawm Qhov Ntev Dhau Los

Cov khoom siv hlau khaws cov kev ntxhov siab seem los ntawm kev siv tshuab thiab kev kho cua sov. Tau ntau lub hlis thiab ntau xyoo, cov kev ntxhov siab sab hauv no maj mam tso tawm, ua rau muaj kev hloov pauv ntawm qhov loj me—ua rau cov khoom siv ntsuas ntsuas tsis zoo uas yuav tsum tau nrhiav kev ntsuas.

Granite, ua ib lub pob zeb igneous ntuj, twb tau dhau los ntawm ntau lab xyoo ntawm geological "annealing." Nws cov crystalline matrix qhia txog kev nkag mus lossis kev ntxhov siab so, tswj hwm qhov flatness specifications (<1μm/1000mm) mus ib txhis nyob rau hauv kev siv kom raug.
