Nyob rau hauv niaj hnub no lub ntiaj teb no ultra-precision manufacturing, qhov tseeb yog ntsuas nyob rau hauv microns thiab txawm nanometers, qhov me tshaj vibration los yog thermal hloov yuav txiav txim tau zoo los yog tsis ua hauj lwm. Raws li kev lag luam txuas ntxiv thawb cov ciam teb ntawm kev ntsuas thiab machining, qhov kev thov rau qhov ruaj khov, txhim khu kev qha, thiab ruaj khov siv tsis tau ntau dua. Qhov no yog qhov uas precision granite platforms sawv sib nrug - yug los ntawm ntau lab xyoo ntawm ntuj tsim geological thiab engineered los ntawm niaj hnub precision txheej txheem, lawv tau dhau los ua qhov tsis sib haum xeeb ntawm kev ntsuas qhov tseeb.
Qhov zoo ntawm granite pib tob hauv pob zeb nws tus kheej. Cov ntaub ntawv zoo xws li Zhhimg® dub granite lossis jinan ntsuab granite yog xaiv rau lawv cov qauv tuab, hnav zoo nkauj homogrity. Cov pob zeb no tau dhau los ua kev laus laus los tso cov kev ntxhov siab sab hauv los ntawm lub sijhawm geological. Raws li qhov tshwm sim, granite muaj qhov tsis tshua muaj thermal expansion - feem ntau tsuas yog 0.5 txog 1.2 × 10⁻⁶ / ° C - uas yog ib feem peb lossis tsawg dua ntawm cov hlau cam khwb cia. Qhov kev nthuav dav qis no txhais tau hais tias granite yog ze li tsis cuam tshuam los ntawm kev hloov pauv kub, tswj kev ruaj khov nyob rau lub sijhawm ntev thiab ua kom ntseeg tau qhov ntsuas qhov tseeb txawm tias nyob hauv qhov hloov pauv ntawm lub rooj cob qhia.
Lwm tus yam ntxwv ntawm precision granite platforms yog lawv qhov tshwj xeeb kev co damping. Cov crystalline microstructure ntawm granite absorbs thiab dissipates vibrations deb zoo dua li cov ntaub ntawv hlau - mus txog kaum npaug zoo dua cam khwb cia hlau. Cov cuab yeej no tseem ceeb heev nyob rau hauv ib puag ncig uas tso siab rau cov cuab yeej siv siab xws li interferometers, kev sib koom tes ntsuas tshuab (CMMs), thiab ntsuas qhov muag. Los ntawm kev txo qis kev vibration thiab resonance, granite tsim "tsim" qhov chaw ntsuas qhov chaw uas cov ntaub ntawv tseem huv thiab rov ua dua.
Granite tseem muab cov tawv tawv tsis sib xws, hnav tsis kam, thiab corrosion kuj. Nws tiv taus khawb thiab tshuaj corrosion, khaws nws cov tiaj tus rau ntau xyoo nyob rau hauv kev siv ib txwm, thiab yuav tsum tsis muaj kev saib xyuas - tsis zoo li cov hlau cam khwb cia, uas yuav tsum tsis tu ncua khawb thiab kho cov xeb. Ntxiv mus, granite yog ib txwm tsis muaj hlau nplaum, ua rau nws zoo tagnrho rau chav kuaj thiab ib puag ncig rhiab rau kev cuam tshuam sib nqus, xws li MRI cov chaw lossis cov cuab yeej ntsuas qhov tseeb.
Cov yam ntxwv no ua rau precision granite platforms indispensable nyob rau hauv kev lag luam uas cia siab rau qhov raug thiab stability. Lawv ua lub hauv paus rau kev sib koom tes ntsuas tshuab, laser interferometers, optical comparators, thiab roundness testers siv los ntawm lub teb chaws metrology institutes thiab advanced kev tshawb fawb soj ntsuam. Nyob rau hauv kev lag luam semiconductor, lawv txhawb wafer tshuaj xyuas tshuab thiab lithography tshuab qhov twg stability ncaj qha cuam tshuam rau nti tawm. Nyob rau hauv precision machining thiab optics, granite hauv paus muab kev txhawb nqa zoo ib yam rau kev sib tsoo ultra-precision thiab milling tshuab, kom ntseeg tau qhov zoo tshaj plaws ntawm qhov tiav thiab qhov kev ntseeg siab. Txawm tias nyob rau hauv kev tshawb fawb, los ntawm gravitational yoj nrhiav kom tau mus rau biomedical instrumentation, granite ua hauj lwm raws li lub hauv paus ntseeg siab uas ua rau thwmsim ruaj khov thiab raug.
Xaiv qhov tsim nyog precision granite platform cuam tshuam ntau dua li xaiv qhov loj lossis tus nqi. Cov yam ntxwv xws li cov khoom zoo, kev tsim qauv, thiab kev tsim khoom siv tes ua txiav txim siab ua haujlwm ntev. Cov platforms yuav tsum ua kom tau raws li cov qhab nia raug lees paub (00, 0, lossis 1) raws li ISO lossis cov qauv ntsuas ntsuas hauv tebchaws, thiab cov tuam txhab tsim khoom yuav tsum muaj peev xwm muab daim ntawv pov thawj kev soj ntsuam thib peb. Cov txheej txheem Advanced xws li precision lapping, natural aging, thiab ceev faj ribbed structural kev txhawb nqa tsim pab kom lub platform tswj tsawg deformation nyob rau hauv load.
Thaum piv rau cov tsoos cam khwb cia hlau hauv paus, granite kom meej meej zoo. Nws nthuav tawm kev ruaj ntseg dua, zoo dua damping, superior hnav tsis kam, thiab txo tus nqi txij nkawm, thaum muaj kev tiv thaiv corrosion thiab cov hlau nplaum nruab nrab. Txawm hais tias tus nqi pib ntawm granite yuav siab dua, nws lub neej ntev thiab kev ua kom zoo ib yam ua rau nws muaj kev lag luam ntau dua thiab txhim khu kev lag luam nyob rau lub sijhawm ntev.
Nyob rau hauv qhov tseeb, lub precision granite platform tsis yog ib pob zeb xwb - nws yog lub hauv paus ntsiag to ntawm kev ntsuas niaj hnub thiab kev tsim khoom. Nws qhia txog lub tuam txhab kev cog lus rau qhov raug, sib xws, thiab kev ua tau zoo. Raws li kev lag luam txav mus rau cov qauv siab dua ntawm qhov tseeb, xaiv lub platform granite yog kev nqis peev tsis yog hauv cov cuab yeej siv tab sis yav tom ntej ntawm kev ntsuas kev ntseeg tau nws tus kheej.
