Hauv kev tsim khoom siv high-precision, tshwj xeeb tshaj yog hauv kev ua semiconductor, micro-lithography, thiab Automated Optical Inspection (AOI), qhov ruaj khov ntawm cov qauv thiab qhov ruaj khov ntev yog qhov tseem ceeb heev. Kev xaiv cov khoom siv hauv paus txiav txim siab qhov kev tiv thaiv ntawm tag nrho lub cev rau kev hloov pauv thermal, kev co tshuab, thiab kev hloov pauv ntawm cov qauv dhau sijhawm. Txawm hais tias qhov kev ntsuas qis-micron tam sim no yog qhov pib hauv kev lag luam, qhov teeb meem tseem muaj nyob ntawm cov neeg muag khoom qis-tier: hloov cov granite precision zoo nrog cov marble qib lag luam kom txo cov nqi tsim khoom.
Los ntawm kev tshawb fawb txog engineering thiab metrological, kev ntsuam xyuas ob lub qauv geological no qhia tau tias vim li cas marble lag luam tsis ua raws li cov kev cai nruj uas yuav tsum tau ua rau cov tshuab kev lag luam siab heev, thiab vim li cas cov marble dub thiaj li tau ntawv pov thawj.cov seem granitetus qauv thoob ntiaj teb.
1. Cov Khoom Siv Ceev thiab Cov Qauv Sab Hauv
Qhov sib txawv tseem ceeb ntawm cov pob zeb granite zoo tshaj plaws thiab marble yog nyob rau hauv lawv cov qauv geological thiab cov khoom siv mineral matrix. Cov pob zeb marble lag luam yog pob zeb metamorphic feem ntau yog tsim los ntawm cov minerals recrystallized carbonate, xws li calcite lossis dolomite. Cov khoom no ua rau cov qauv minerals mos mos nrog porosity siab dua.
Ntawm qhov tod tes, cov pob zeb dub granite uas yog qib precision—tshwj xeeb yog cov khoom siv uas tau tsim los ntawm kev saib xyuas nruj zoo li ZHHIMG® Black Granite—yog pob zeb igneous uas nkag mus rau hauv. Nws muaj cov qauv crystalline ntom ntom, sib txuas ua ke nplua nuj hauv gabbro thiab diabase.

Kev Nthuav Dav Dynamics: Cov pob zeb marble lag luam feem ntau muaj qhov ntom ntawm 2,500 txog 2,700 kg / m³. Qhov sib piv, ZHHIMG® Black Granite ua tiav cov matrix ntom txog li 3,100 kg / m³.
-
Kev Cuam Tshuam Txog Kev Tsim Kho: Cov pob zeb loj muaj feem cuam tshuam ncaj qha rau kev ruaj khov ntawm cov qauv thiab qhov porosity qis dua. Kev ceev ceev txo qis kev nqus dej noo, tiv thaiv kev hloov pauv ntawm lub zog hydrostatic sab hauv uas ua rau muaj kev sib txhuam me me dhau sijhawm. Rau cov khoom siv ua haujlwm ntawm qhov kev daws teeb meem nanometer, txawm tias qhov kev hloov pauv ntawm cov qauv 0.5-micron tuaj yeem cuam tshuam kev sib dhos ntawm lub teeb lossis kev taug qab ntawm lub cev muaj zog.
2. Kev Ruaj Ntseg Thermal thiab Co-efficient ntawm Thermal Expansion (CTE)
Cov chaw tsim khoom semiconductor thiab chav huv si ua haujlwm nyob rau hauv qhov chaw tswj hwm zoo, txawm li cas los xij, qhov kub hnyiab hauv zos los ntawm cov motors linear, XY theem, thiab cov khoom siv hluav taws xob yog qhov tsis zam. Lub hauv paus qauv yuav tsum muaj Coefficient of Thermal Expansion (CTE) qis heev thiab thermal inertia siab kom tiv taus qhov deformation hauv zos.
| Khoom siv | Marble lag luam | ZHHIMG® Dub Granite | Kev Pab Cuam Engineering |
| Qhov Nruab Nrab Ceev | ~2,600 kg/m³ | ~3,100 kg/m³ | Kev nruj dua, qhov hnyav ntawm cov qauv |
| Porosity & Dej Nqus | Siab (0.5% – 2.0%) | Qis Kawg Nkaus (<0.1%) | Tiv thaiv kom tsis txhob muaj cov kab mob me me uas ua rau muaj dej noo |
| Kev Nthuav Dav Kub (CTE) | Siab & Hloov Pauv | Tsawg kawg thiab sib xws | Tiv thaiv kev kub hnyiab ntawm lub cev muaj zog |
| Kev co damping peev xwm | Tsis Zoo (Kev Sib Txhuam Sab Hauv Qis) | Zoo heev (Cib Cib Crystal Ntws) | Kev txo qis sai ntawm lub zog zaus siab |
Marble muaj cov yam ntxwv thermal isotropic heev tab sis muaj qhov thermal expansion rate siab dua li granite. Ntxiv mus, vim nws cov calcite base softer, marble qhia txog cov thermal gradients hauv zos, ua rau muaj kev nthuav dav tsis sib xws thoob plaws 5000mm base. Precision black granite tswj hwm qhov ze-xoom structural deformation nyob rau hauv qhov kub thiab txias hloov pauv, xyuas kom meej tias cov geometric alignments tseem ceeb - xws li straightness, flatness, thiab perpendicularity - tseem ruaj khov thaum lub sijhawm ua haujlwm tshuab tas mus li.
3. Kev Rigidity, Hardness, thiab Hand-Lapping Potential
Kev ntsuas kev lag luam thiabcov hauv paus tshuabraug rau cov khoom thauj dynamic tas mus li los ntawm kev hloov pauv ntawm lub cev muaj zog linear ceev. Lub txaj qauv yuav tsum tiv taus cov zog no yam tsis muaj kev hloov pauv elastic.
Ntawm Mohs hardness scale, marble feem ntau qhab nia ntawm 3 thiab 4, ua rau nws yooj yim rau khawb, indentation, thiab cov khoom puas tsuaj. Precision black granite qib ntawm 6 thiab 7, muab kev tiv thaiv zoo dua rau kev hnav lub cev thiab deformation.
Qhov hardness factor no yog ncaj qha khi rau qhov tseeb geometric kawg uas tau ua tiav thaum lub sijhawm tsim khoom:
-
Cov Kev Txwv ntawm Kev Siv Tshuab: Thaum cov chaw sib tsoo CNC siab heev (xws li cov chaw sib tsoo Nante siab heev) tuaj yeem ua tiav cov qauv me me, qhov kawg nanometer-level flatness uas xav tau rau AOI thiab semiconductor theem yuav tsum tau ua tiav los ntawm kev siv tes lapping.
-
Theem Kev Sib Txhuam Tes: Cov kws tshaj lij uas muaj kev paub dhau los—feem ntau siv ntau tshaj 30 xyoo ntawm kev siv tes los kov cov khoom raws li cov qauv thoob ntiaj teb xws li DIN 876 lossis ASME B89—siv cov khoom siv tawv, sib xws los tshem tawm cov khoom kom meej txog li micron fractions.
-
Qhov Tsis Zoo ntawm Pob Zeb: Vim tias pob zeb mos thiab tsis ruaj khov (feem ntau yuav ua rau muaj cov kua qaub lossis cov dej noo hauv ib puag ncig), kev sib tsoo tes ua rau muaj qhov tawg me me es tsis yog kev sib txhuam huv. Nws tsis tuaj yeem tuav tau qhov kev kam rau siab mus rau qib nanometer hla ntau qhov loj.
4. Kev Tiv Thaiv Kev co thiab Kev cuam tshuam ntawm cov qauv
Cov platforms XY linear motors uas muaj kev kub ceev tsim cov zog dynamic loj thaum lub sijhawm acceleration thiab deceleration. Yog tias lub hauv paus tshuab tsis muaj peev xwm damping sab hauv txaus, cov zog no ua rau muaj kev cuam tshuam ntawm cov qauv, ua rau lub sijhawm settling ntev dua thiab txo cov khoom siv hauv kev tshuaj xyuas semiconductor.
Cov pob zeb granite dub uas muaj cov pob zeb ntom ntom thiab sib txuas ua ke ua cov khoom siv suab thiab cov khoom siv kho tshuab. Kev sib txhuam sab hauv hla cov ciam teb siv lead ua rau lub zog kinetic siab dua li cov pob zeb carbonate uas mos dua thiab sib xws. Kev xaiv cov pob zeb marble qis dua yuav ua rau muaj kev co me me uas cuam tshuam cov kev ntsuas pom kev theem ob, cov koob yees duab soj ntsuam, thiab kev nyeem laser interferometry.
Kev Ncaj Ncees ntawm Cov Qauv Ua Tus Qauv Kev Lag Luam
Rau cov chaw tsim khoom thoob ntiaj teb uas muab kev pabcuam rau cov khoom siv hluav taws xob, tsheb, thiab aerospace, kev ntseeg tau ntawm cov khoom siv tsis tuaj yeem raug txo qis. Kev siv cov hauv paus marble qis dua raws li "lub hauv paus pob zeb lag luam" yog qhov tseem ceeb ntawm kev ua tsis tiav hauv kev tsim cov tshuab siab heev.
Kev tswj hwm qhov pom tseeb tag nrho los ntawm cov qauv zoo nruj - xws li tuav cov ntawv pov thawj ISO 9001, ISO 14001, thiab ISO 45001 tib lub sijhawm - ua kom ntseeg tau tias cov khoom siv tseem raug txheeb xyuas. Cov khoom siv precision siv cov ZHHIMG® Black Granite tiag tiag lav tias los ntawm kev rho tawm cov khoom nyoos mus rau qhov kawg ntawm lub koom haum hauv tebchaws-lub koom haum-taug qab metrology calibration, cov khoom siv lub cev ua raws li qhov xav tau ntawm kev tsim kho ultra-precision. Hauv qab sub-micron tolerances, tsis muaj kev hloov pauv rau qhov ceev ntawm cov qauv thiab kev ruaj khov geological.
