Hauv lub ntiaj teb kev ua haujlwm siab ntawm kev tsim kho qhov tseeb, kev nrhiav kev raug ntawm sub-micron feem ntau ua rau cov engineers rov qab mus rau cov khoom siv los ntawm xwm nws tus kheej. Thaum peb taug kev cov kev xav tau nyuaj ntawm kev tsim khoom lag luam hauv xyoo 2026, kev cia siab rau cov ntaub ntawv ua tau zoo tsis tau tseem ceeb dua. Ntawm ntau yam kev daws teeb meem muaj, lub hauv paus precision granite dub sawv tawm ua tus qauv kub rau kev ruaj khov. Ntawm ZHHIMG, peb tau pom qhov kev hloov pauv tseem ceeb hauv kev lag luam thoob ntiaj teb - xws li aerospace mus rau semiconductor metrology - mus rau qhov kev ncaj ncees ntawm lawv cov txheej txheem ntsuas.
Qhov zoo tshaj plaws ntawm lub hauv paus granite dub precision yog nyob rau hauv nws cov khoom zoo kawg nkaus. Tsis zoo li cov hlau cam khwb cia lossis hlau, uas yooj yim rau kev ntxhov siab sab hauv thiab thermal distortion, granite muaj qib ntawm kev co damping thiab thermal inertia uas yog qhov tseem ceeb rau kev ntsuas zaus siab. Qhov kev ruaj khov no yog qhov tseem ceeb tshwj xeeb thaum tsim aprecision granite pedestal puagrau cov khoom siv kho qhov muag lossis cov khoom siv kho tshuab uas rhiab heev. Thaum ib lub cuab yeej raug teeb tsa rau ntawm lub pedestal zoo li no, nws raug cais tawm ntawm cov micro-vibrations ntawm lub Hoobkas pem teb, uas tso cai rau qib rov ua dua uas cov qauv hlau tsis tuaj yeem ua tau ntev.
Ib qho piv txwv tseem ceeb ntawm daim ntawv thov tshwj xeeb no yog kev tsim cov granite puag rau Universal length measuring instrument (ULM). ULM feem ntau yog tus thawj coj kawg hauv chav kuaj calibration, uas muaj lub luag haujlwm los xyuas qhov ntev ntawm cov gauge blocks thiab master plugs qhov twg qhov kev kam rau siab ntsuas hauv nanometers. Rau cov cuab yeej zoo li no, lub phaj nto txheem tsis txaus. Lub granite puag rau Universal length measuring instrument yuav tsum tau tsim nrog cov yam ntxwv geometric tshwj xeeb, xws li precision-lapped T-slots, integrated guideways, thiab strategically placed threaded inserts. Cov yam ntxwv no tso cai rau lub cuab yeej lub tailstock thiab lub taub hau ntsuas kom glide nrog linearity zoo meej thiab xoom stick-slip effect, kom ntseeg tau tias qhov kev siv tshuab tseem nyob thoob plaws hauv tag nrho qhov ntsuas.
Cov kev xav tau ntawm kev lag luam niaj hnub no feem ntau nthuav dav tshaj qhov chaw nws tus kheej. Hauv cov chaw ntsuas loj thiab cov tshuab ntsuas sib koom tes, kev siv cov ntoo txhawb nqa granite tau dhau los ua qhov kev xaiv tsim tseem ceeb. Cov ntoo no yuav tsum tswj tau qhov ncaj heev hla ntau meters thaum txhawb nqa qhov hnyav ntawm cov tsheb thauj khoom thiab cov khoom soj ntsuam. Ib qho ntawm cov txiaj ntsig tseem ceeb tshaj plaws ntawmgranite txhawb nqa beamsyog lawv txoj kev tiv thaiv rau "creep" lossis deformation ntev. Txawm hais tias cov hlau txhuas yuav sag lossis warp nyob rau hauv qhov hnyav tas li lossis qhov kub thiab txias hloov pauv, granite tswj nws cov lapped raug thawj rau ntau xyoo caum. Qhov kev ua neej ntev no txo cov nqi tag nrho ntawm kev muaj rau OEMs thiab cov neeg siv kawg, vim tias qhov xav tau kev them nyiaj software ntau zaus thiab kev rov ua dua lub cev tau txo qis.
Thaum tsim ib lub chaw ua haujlwm rau lub chaw kuaj mob siab, kev koom ua ke ntawm ib qhoprecision granite pedestal puagfeem ntau ua haujlwm ua lub hauv paus tseem ceeb ntawm cov txheej txheem tshuaj xyuas. Cov pedestals no tsis yog tsuas yog cov pob zeb xwb; lawv yog cov khoom tsim kho siab heev uas dhau los ntawm cov txheej txheem ntawm kev ruaj khov thermal thiab tes-lapping. Ntawm ZHHIMG, peb cov kws tshaj lij siv sijhawm ntau pua teev los kho cov chaw no kom ua tiav qhov tiaj tiaj uas tshaj cov qauv thoob ntiaj teb xws li DIN 876 Qib 000. Qib kev ua haujlwm no ua kom ntseeg tau tias lub pedestal muab qhov kev siv orthogonal zoo meej rau kev ntsuas ntsug, uas yog qhov tseem ceeb rau cov neeg sim siab micro-hardness thiab laser interferometry systems.
Tsis tas li ntawd xwb, qhov zoo nkauj thiab kev ua haujlwm zoo ntawm lub hauv paus granite dub muab ib puag ncig uas tsis muaj kev cuam tshuam, tsis muaj hlau nplaum, thiab tsis muaj xeb. Hauv chav huv lossis ib puag ncig uas kev cuam tshuam hlau nplaum tuaj yeem ua rau cov ntaub ntawv sensor hluav taws xob tsis sib xws, granite tseem nyob twj ywm kiag li. Qhov no ua rau nws yog cov khoom siv zoo tshaj plaws rau cov kab ke sib xyaw uas sib xyaw ua ke kev luam theej duab nrog kev soj ntsuam kho tshuab. Los ntawm kev sivgranite txhawb nqa beamsthiab cov hauv paus tsim tshwj xeeb, cov chaw tsim khoom tuaj yeem tsim ib lub hnab ntawv sib koom ua ke uas tsis muaj teeb meem ntawm cov chaw ua haujlwm hauv kev lag luam.
Thaum peb saib mus rau yav tom ntej ntawm kev tswj xyuas zoo tsis siv neeg, lub luag haujlwm ntawm cov khoom siv precision no tsuas yog yuav loj hlob xwb. Kev sib koom ua ke ntawm cov khoom siv ntuj thiab cov txheej txheem machining siab heev tso cai rau ZHHIMG thawb cov ciam teb ntawm qhov ua tau hauv qhov ntsuas qhov ntev. Txawm hais tias nws yog lub hauv paus granite kev cai rau Universal ntev ntsuas ntsuas tsim rau lub teb chaws tus qauv lab lossis ib qho ntawm cov granite txhawb nqa beams rau cov kab tshuaj xyuas semiconductor ceev ceev, lub hom phiaj tseem zoo li qub: muab lub hauv paus uas tsis muaj kev cuam tshuam zoo li cov cai ntawm physics. Kev nqis peev rau hauv cov kev daws teeb meem granite precision no yog kev nqis peev rau kev ntseeg siab thiab qhov tseeb ntawm lub ntiaj teb cov thev naus laus zis ntsuas uas xav tau tshaj plaws.
