Hauv lub ntiaj teb kev tsim khoom siv niaj hnub no, qhov twg qhov tseeb raug ntsuas hauv microns thiab txawm tias nanometers, qhov kev co me tshaj plaws lossis kev hloov pauv thermal tuaj yeem txiav txim siab qhov ua tiav lossis tsis ua tiav. Raws li kev lag luam txuas ntxiv thawb cov ciam teb ntawm kev ntsuas thiab kev siv tshuab, qhov kev thov rau qhov chaw ruaj khov, txhim khu kev qha, thiab ruaj khov tsis tau muaj ntau dua. Qhov no yog qhov twg cov platform granite precision sawv sib nrug - yug los ntawm ntau lab xyoo ntawm kev tsim geological ntuj thiab tsim los ntawm cov txheej txheem niaj hnub precision, lawv tau dhau los ua tus qauv tsis muaj kev sib cav ntawm qhov tseeb ntawm kev ntsuas.
Qhov zoo ntawm granite pib tob hauv lub pob zeb nws tus kheej. Cov ntaub ntawv zoo xws li ZHHIMG® Black Granite lossis Jinan Green Granite raug xaiv rau lawv cov qauv ntom ntom, cov noob sib xws, thiab kev sib xws zoo heev. Cov pob zeb no dhau los ua kev laus ntuj kom tso tawm cov kev ntxhov siab sab hauv uas tau sau los ntawm lub sijhawm geological. Yog li ntawd, granite muaj kev nthuav dav thermal qis heev - 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 tias granite yuav luag tsis cuam tshuam los ntawm kev hloov pauv kub, tswj kev ruaj khov ntev thiab ua kom ntseeg tau tias qhov ntsuas tau zoo txawm tias nyob rau hauv cov xwm txheej kev ua haujlwm hloov pauv.
Lwm yam ntxwv ntawm cov platform granite precision yog lawv qhov kev co damping tshwj xeeb. Lub microstructure crystalline ntawm granite nqus thiab dissipates kev co zoo dua li cov khoom siv hlau - txog li kaum npaug zoo dua li cov hlau cam khwb cia. Cov khoom no yog qhov tseem ceeb hauv cov chaw uas vam khom cov cuab yeej daws teeb meem siab xws li interferometers, cov tshuab ntsuas sib koom ua ke (CMMs), thiab cov tshuab ntsuas optical. Los ntawm kev txo qis kev co thiab resonance, granite tsim ib puag ncig ntsuas "ntsiag to" qhov twg cov ntaub ntawv tseem huv thiab rov ua dua.
Granite kuj muaj qhov nyuaj, tsis yooj yim hnav, thiab tsis yooj yim xeb. Nws tiv taus khawb thiab tshuaj lom neeg, khaws nws qhov tiaj tiaj rau ntau xyoo hauv kev siv ib txwm, thiab yuav luag tsis tas yuav saib xyuas - tsis zoo li cov hlau cam khwb cia, uas yuav tsum tau khawb thiab kho tsis tu ncua tiv thaiv xeb. Ntxiv mus, granite yog ntuj tsis muaj hlau nplaum, ua rau nws zoo tagnrho rau cov chaw kuaj mob thiab cov chaw ib puag ncig uas rhiab rau kev cuam tshuam hlau nplaum, xws li MRI chaw lossis cov khoom siv kuaj mob.
Cov yam ntxwv no ua rau cov platform granite precision tsis tseem ceeb thoob plaws cov lag luam uas vam khom qhov tseeb thiab kev ruaj khov. Lawv ua haujlwm ua lub hauv paus rau cov tshuab ntsuas kev sib koom tes, laser interferometers, optical comparators, thiab cov roundness testers siv los ntawm lub teb chaws metrology institutes thiab cov chaw soj ntsuam siab heev. Hauv kev lag luam semiconductor, lawv txhawb nqa wafer inspection systems thiab lithography machines qhov twg kev ruaj khov cuam tshuam ncaj qha rau chip yield. Hauv precision machining thiab optics, granite bases muab kev txhawb nqa tas li rau ultra-precision grinding thiab milling machines, kom ntseeg tau tias qhov chaw tiav zoo dua thiab qhov ntev. Txawm tias nyob rau hauv kev tshawb fawb, los ntawm gravitational wave detection mus rau biomedical instrumentation, granite ua haujlwm ua lub hauv paus ntseeg siab uas ua rau kev sim ruaj khov thiab raug.
Kev xaiv lub platform granite precision uas tsim nyog muaj ntau dua li kev xaiv qhov loj me lossis tus nqi tsim nyog. Cov yam xws li cov khoom siv zoo, kev tsim qauv, thiab kev ua haujlwm tsim khoom txiav txim siab qhov kev ua tau zoo mus sij hawm ntev. Cov platforms yuav tsum ua tau raws li qib raug lees paub (00, 0, lossis 1) raws li ISO lossis cov qauv ntsuas hauv tebchaws, thiab cov chaw tsim khoom yuav tsum muaj peev xwm muab daim ntawv pov thawj tshuaj xyuas sab nraud. Cov txheej txheem siab heev xws li kev lapping precision, kev laus ntuj, thiab kev tsim qauv txhawb nqa ribbed ceev faj pab ua kom lub platform tswj hwm qhov deformation tsawg kawg nkaus hauv qab load.
Thaum piv rau cov hlau cam khwb cia ib txwm muaj, granite zoo dua. Nws muaj kev ruaj khov dua, zoo dua damping, zoo dua hnav tsis kam, thiab tus nqi txij nkawm qis dua, thaum nws tsis xeb thiab tsis muaj hlau nplaum. Txawm hais tias tus nqi pib ntawm granite yuav siab dua, nws lub neej ntev thiab kev ua haujlwm raug ua rau nws yog qhov kev nqis peev pheej yig dua thiab txhim khu kev qha rau lub sijhawm ntev.
Hauv paus ntsiab lus, lub platform granite precision tsis yog ib daim 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 txoj kev cog lus rau qhov tseeb, kev sib xws, thiab kev ua tau zoo tshaj plaws. Thaum cov lag luam txav mus rau cov qauv siab dua ntawm kev ua tau zoo, kev xaiv lub platform granite yog kev nqis peev tsis yog rau cov khoom siv xwb tab sis kuj rau yav tom ntej ntawm kev ntseeg siab ntawm kev ntsuas nws tus kheej.
