Hauv kev nrhiav kom tau qhov geometry zoo meej, kev xaiv lub dav hlau siv yog qhov kev txiav txim siab tseem ceeb tshaj plaws uas tus engineer tuaj yeem ua tau. Raws li kev tsim khoom thoob ntiaj teb thawb mus rau ciam teb ntawm "nanometer hnub nyoog," qhov kev thov rau kev ruaj khov ntawm lub cev yeej tsis tau muaj kev kub ntxhov ntau dua. Thaum cov hlau nplaum thiab cov khoom sib xyaw ua ke muaj lawv qhov chaw hauv kev tsim kho vaj tse, cov granite dub ntuj tseem yog tus huab tais tsis muaj kev sib cav ntawm lub chaw kuaj metrology. Ntawm ZHHIMG, peb txoj kev cog lus los muab lub hauv paus zoo tshaj plaws rau kev ntsuas yog pom tseeb hauv peb cov khoom tsim tshwj xeeb ntawm cov phaj granite nto meej, lubgranite square ntsuas, thiab lub hauv paus granite ruaj khov siab.
Kev hloov pauv ntawm cov hlau cam khwb cia mus rau granite thaum nruab nrab xyoo pua 20th tau hloov pauv kev tswj hwm zoo. Niaj hnub no, thaum peb txhawb nqa cov lag luam xws li aerospace mus rau semiconductor lithography, qhov kev tsom mus rau tau hloov pauv ntawm "kev tiaj tiaj" mus rau "kev ncaj ncees mus sij hawm ntev." Kev nkag siab txog qhov sib txawv ntawm cov cuab yeej no yog qhov tseem ceeb rau txhua qhov chaw uas tsom mus rau ISO / IEC 17025 kev ua raws li lossis kev ua tau zoo ntawm kev tsim khoom dav dav.
Lub Rooj Sib Tham ntawm Lub Chaw Kuaj Mob: Lub Phaj Nto Granite Uas Muaj Kev Ntsuas Zoo
Txhua qhov kev ntsuas pib nrog ib qho xoom. Qhov kev ua kom rauggranite nto phajua haujlwm ua qhov kev siv kab rov tav. Ntawm ZHHIMG, peb tau txais cov hom granite dub tshwj xeeb - feem ntau hu ua "Jinang Black" - vim nws qhov ceev ceev thiab kev nqus dej tsawg. Tsis zoo li cov granites xim sib dua, peb cov granite dub zoo tshaj plaws muaj feem pua ntawm quartz ntau dua, uas txhais tau tias ncaj qha rau kev tiv thaiv kev hnav zoo dua.
Ib qho teeb meem uas feem ntau ntsib hauv cov chaw ua haujlwm niaj hnub no yog qhov kub hloov pauv. Lub phaj hlau yuav nthuav dav thiab cog lus ntau nrog tsuas yog ob degree Celsius hloov pauv, ua rau cov kev ntsuas siab tsis muaj txiaj ntsig. Qhov sib piv, peb lub phaj granite precision muaj cov coefficient qis ntawm thermal expansion. Qhov kev ruaj khov no ua kom ntseeg tau tias "Qib 00" flatness peb lap rau hauv lub pob zeb ntawm peb lub Hoobkas tseem sib xws thaum nws mus txog koj lub chaw.
Rau cov chaw kuaj mob uas xav tau qib siab tshaj plaws ntawm qhov tseeb, peb muaj cov phaj "Kuaj Mob Qib" (Qib AA/00). Cov no tsis yog tsuas yog tshuab xwb; lawv tau ua tib zoo ntxuav tes. Cov txheej txheem tes no tshem tawm cov "peaks" me me uas tshuav los ntawm CNC sib tsoo, tsim ib qho chaw uas cov theem cua tuaj yeem ya mus yam tsis muaj kev sib txhuam thiab rov ua dua ntau tshaj plaws.
Kev Paub Txog Perpendicularity: Tus Kav Hlau Granite Square
Thaum lub phaj saum npoo kov lub dav hlau kab rov tav, lubgranite square ntsuasyog tus saib xyuas ntawm txoj kab ntsug. Hauv kev ntsuas ntawm CNC machining centers thiab Coordinate Measuring Machines (CMMs), "squareness" yog qhov kev sib tw peb-seem. Ib tug granite square ruler (feem ntau hu ua master square) muab ob lossis ntau qhov chaw uas yog 90 degrees rau ib leeg.
Qhov zoo ntawm kev siv granite rau kev kuaj xyuas qhov sib npaug yog nws qhov rigidity. Cov hlau squares tuaj yeem khoov lossis flex raws li lawv qhov hnyav, tshwj xeeb tshaj yog hauv qhov loj dua. Ib tug granite square ruler los ntawm ZHHIMG yog tsim nrog ib qho kev txiav tshwj xeeb kom ntseeg tau tias nws tseem tsis muaj deflection. Ntxiv mus, yog tias ib tug granite square raug nicked lossis khawb, nws tsis tsim ib tug "burr" zoo li hlau ua. Hloov chaw, ib daim me me ntawm pob zeb tsuas yog flakes tawm, tawm hauv ib puag ncig qhov chaw siv zoo meej tiaj tus thiab raug. Qhov "tsis ua haujlwm-nyab xeeb" no yog vim li cas cov kws tshaj lij aerospace sab saum toj tsis kam siv dab tsi tab sis granite rau lawv cov tswv yim siv.
Kev Ntsuas Qhov Tseeb Ntawm Qhov Chaw Sib Cuag: Lub Hauv Paus Granite Dial
Txawm tias lub cim qhia qhov ntsuas kim tshaj plaws tsuas yog zoo li lub rooj sawv ntsug uas tuav nws. Lub hauv paus ntawm lub cim qhia granite (lossis lub rooj sib piv) muab ib puag ncig uas tsis muaj kev co rau kev tshuaj xyuas siab. Thaum ntsuas qhov kam rau siab hauv qhov ntau ntawm 0.001 hli, cov micro-vibrations los ntawm lub forklift ze lossis lub kiv cua txias tuaj yeem ua rau "koob jitter" ntawm lub cim qhia.
Qhov hnyav ntawm lub hauv paus granite dial ntuj nqus cov kev co siab no. Ntawm ZHHIMG, peb lub hauv paus muaj cov theem granite precision-lapped ua ke nrog cov hlau stainless lossis ceramic kem. Qhov kev tsim kho hybrid no muab qhov zoo tshaj plaws ntawm ob lub ntiaj teb: qhov damping ntawm pob zeb thiab kev hloov kho ntawm cov hlau. Rau cov khoom tsim khoom ntau, lub hauv paus granite dial muab qhov ruaj khov "chaw ua haujlwm" qhov twg cov neeg teb xov tooj tuaj yeem hloov pauv cov khoom yam tsis poob lawv qhov xoom-setting, txo qis lub sijhawm tshuaj xyuas thaum ua kom ntseeg siab rau cov ntaub ntawv.
Tus Txheej Txheem Zoo ntawm ZHHIMG: Ntau Tshaj Li Pob Zeb Xwb
Kev tsim cov cuab yeej no yog ib qho kev tawm dag zog ntawm kev ua siab ntev thiab kev ua kom raug. Ntawm lub chaw ZHHIMG, txhua lub phaj granite nto thiab tus kav plaub fab raug lub sijhawm ruaj khov. Pob zeb nyoos raug tso cai "ua pa" thiab nyob tom qab txiav thawj zaug kom tso tawm cov kev ntxhov siab sab hauv uas tau raug kaw rau ntau lab xyoo.
Tsuas yog tom qab qhov kev ruaj khov no peb cov kws tshaj lij pib ua cov txheej txheem lapping. Siv cov theem hluav taws xob thiab laser interferometers, peb kos duab topology ntawm lub pob zeb, txheeb xyuas "cov chaw siab" uas nyias dua li cov plaub hau tib neeg. Los ntawm kev ntsuas rov ua dua thiab kev lapping tes, peb ua tiav qhov kev kam rau siab sub-micron uas peb cov neeg koom tes thoob ntiaj teb vam khom.
Xaus Lus: Kev Nqis Peev rau Yav Tom Ntej ntawm Kev Ntsuas
Thaum peb saib mus rau qhov yuav tsum tau ua ntawm Kev Lag Luam 4.0, sab "lub cev" ntawm kev ntsuas tseem ceeb npaum li cov sensors digital. Lub digital probe tsis muaj txiaj ntsig yog tias qhov chaw uas nws so yog warped lossis vibrating. Los ntawm kev xaiv lub ZHHIMG precision granite nto phaj, square ruler, lossis dial base, koj tsis yog tsuas yog yuav ib lub cuab yeej - koj tab tom nqis peev rau hauv tus qauv ntev ntawm kev ua tau zoo.
Peb caw cov engineers thiab cov thawj coj zoo los tshawb nrhiav peb cov kev daws teeb meem metrology tag nrho. Txawm hais tias koj xav tau lub phaj tshwj xeeb rau chav huv lossis lub master square hnyav rau kev tsim kho dua tshiab ntawm cov cuab yeej siv tshuab, ZHHIMG muaj cov khoom siv thiab kev txawj ntse los txhawb koj lub hom phiaj meej tshaj plaws.
