Hauv kev tsim khoom siv high-precision, qhov sib txawv ntawm kev ua tiav thiab kev tsis lees txais kim feem ntau yog ob peb microns. Raws li kev lag luam xws li semiconductor lithography, aerospace engineering, thiab electric vehicle powertrain ntau dhau qhov kev kam rau siab, qhov ruaj khov ntawm qhov chaw ntsuas tau dhau los ua qhov tseem ceeb ib yam li cov sensors lawv tus kheej.
Ntawm ZHHIMG, peb nkag siab tias aTshuab Ntsuas Kev Sib Koom Tes (CMM)los yog lub Optical Comparator tsuas yog ntseeg tau raws li lub hauv paus uas nws sawv ntawm. Tsab xov xwm no tshawb nrhiav qhov kev hloov pauv ntawm cov khoom siv metrology thiab vim li cas kev xaiv ntawm lub hauv paus tshuab granite, hlau cam khwb cia, lossis cov txheej txheem kev co siab heev yuav txiav txim siab yav tom ntej ntawm kev tswj hwm zoo.
Kev Hloov Pauv ntawm Kev Ruaj Ntseg ntawm Cov Qauv hauv Metrology
Keeb kwm,cov hlau cam khwb cia tshuab puagyog tus qauv kev lag luam. Lawv lub peev xwm ua kom noo noo siab thiab yooj yim ntawm kev siv tshuab ua rau lawv zoo tagnrho rau lub sijhawm kev lag luam hnyav. Txawm li cas los xij, thaum lub sijhawm ntsuas tau tsiv los ntawm pem teb chaw ua haujlwm mus rau chav kuaj mob uas tswj tau qhov kub, qhov kev txwv ntawm cov hlau - tshwj xeeb tshaj yog nws cov coefficient nthuav dav thermal thiab kev cuam tshuam rau kev ntxhov siab sab hauv - tau pom tseeb.
Kev Sawv ntawm Cov Pob Zeb Ntuj
Niaj hnub no, cov granite dub ntuj tau dhau los ntawm cov hlau cam khwb cia ua tus qauv kub raucov phaj nto precisionthiab cov qauv CMM. Cov laj thawj yog cov hauv paus hauv physics:
-
Kev Ruaj Ntseg Thermal: Granite muaj cov coefficient qis dua ntawm kev nthuav dav thermal piv rau hlau lossis hlau. Hauv ib puag ncig uas 1 ° C hloov pauv tuaj yeem ua rau kev ntsuas puas tsuaj, granite "thermal inertia" muab qhov tseem ceeb buffer.
-
Kev Tiv Thaiv Kev Xeb: Tsis zoo li hlau, granite tsis xeb lossis xeb, ua kom ntseeg tau tias lub dav hlau siv tseem zoo nkauj tshaj li ntau xyoo ntawm kev siv yam tsis tas yuav siv roj lossis tshuaj tiv thaiv.
-
Kev Txo Kev Nyuaj Siab Sab Hauv: Cov pob zeb granite ntuj tau laus rau ntau lab xyoo hauv qab lub ntiaj teb lub plhaub, txhais tau tias nws tsis muaj kev nyuaj siab sab hauv uas pom muaj nyob rau hauv cov qauv cam khwb cia lossis vuam.
Kev Tsim Kho Lub Tshuab Ntsuas Sib Koom Tes Zoo Tshaj Plaws (CMM) Lub Hauv Paus
Lub Tshuab Ntsuas Kev Sib Koom Tes niaj hnub xav tau ntau dua li qhov chaw tiaj tus xwb; nws xav tau kev ruaj khov dynamic. Thaum lub choj CMM txav mus los ntawm kev kub ceev, nws tsim cov zog inertial. Yog tiasgranite tshuab puagtsis tau tsim nrog qhov sib piv ntawm qhov hnyav thiab qhov nruj kom raug, cov zog no txhais ua cov kev co me me uas ua rau qhov ntsuas "tsis paub meej" ntawm lub tshuab poob qis.
Ntawm ZHHIMG, peb pab neeg engineering tsom mus rau kev koom ua ke ntawm lub hauv paus nrog cov kev taw qhia tshuab. Los ntawm kev siv cov khoom granite precision-lapped, peb xyuas kom meej tias cov huab cua bearings ntawm CMM glide hla ib qho chaw nrog ib qho flatness ntsuas hauv lub teeb bands.
Tshaj Granite: Cov Ntaub Ntawv Rau Cov Rooj Sib Cais Kev co
Txawm tias lub hauv paus granite ruaj khov tshaj plaws los tsis tuaj yeem tiv thaiv tau cov yam ntxwv ib puag ncig sab nraud. Rau cov chaw nyob ze ntawm txoj kev tsheb ciav hlau hnyav, txoj kev loj, lossis cov tshuab luam ntawv hnyav, kev co hauv av yog qhov tua tsis muaj suab nrov ntawm qhov tseeb.
Ib lub rooj cais kev co ua haujlwm ua lub lim dej qis rau cov khoom siv. Los ntawm kev siv lub tshuab cua lossis lub tshuab hluav taws xob ua haujlwm, cov rooj no cais cov khoom siv ntsuas ntawm lub tsev hauv pem teb. Rau nanotechnology thiab kev tshuaj xyuas qhov muag, qhov twg kev ntsuas tshwm sim ntawm qhov ntsuas nanometer, qhov kev cais no tsis yog "kev hloov kho xaiv tau" - nws yog qhov yuav tsum tau ua.
Kev Sib Piv Cov Khoom Siv: Granite, Cast Iron, thiab Mineral Casting
Rau cov neeg ua haujlwm yuav khoom thiab cov thawj coj engineers, kev xaiv cov khoom siv zoo suav nrog kev sib npaug ntawm kev ua tau zoo nrog tus nqi thiab qhov hnyav.
| Vaj tse | Pob zeb granite ntuj | Hlau cam khwb cia (GC25/30) | Kev Ua Hlau Casting |
| Qhov Ceev | ~3000 kg/m³ | ~7200 kg/m³ | ~2400 kg/m³ |
| Kev nthuav dav thermal | 5.5 × 10^{-6}/K | 10-12 × 10^{-6}/K | 12 × 10^{-6}/K |
| Kev co damping | Siab | Nruab Nrab | Zoo heev |
| Kev Pheej Hmoo ntawm Kev Xeb | Tsis muaj dab tsi | Siab | Tsis muaj dab tsi |
| Muaj Peev Xwm Tseeb | Qib 000 | Qib 0 | Qib 1 |
Txawm hais tias granite yeej qhov tseeb ntawm kev ua kom raug, kev ua kom cov pob zeb hauv av tau txais kev nyiam rau cov chaw tsim khoom ntau vim nws muaj peev xwm raug pov rau hauv cov duab nyuaj nrog cov kav dej txias thiab cov ntxig rau kev teeb tsa. Txawm li cas los xij, rau qhov siv tseem ceeb - lub phaj nto precision - granite ntuj tseem tsis tau muaj leej twg sib tw.
Qhov Zoo ntawm ZHHIMG: Tsim Lub Neej Yav Tom Ntej ntawm Metrology
Vim li cas cov thawj coj thoob ntiaj teb hauv cov khoom siv semiconductor thiab automotive thiaj xaiv ZHHIMG? Nws yog nyob ntawm peb txoj kev siv tag nrho rau cov khoom siv metrology. Peb tsis yog "txiav pob zeb" xwb; peb tsim cov kev daws teeb meem.

-
Kev daws teeb meem sib xyaw ua ke: Los ntawm lub hauv paus tshuab hlau cam khwb cia siv rau hauv kev ua haujlwm hnyav mus raulub rooj cais kev cosiv rau hauv kev sib cuam tshuam dawb-lub teeb, ZHHIMG muab tag nrho cov kev txhawb nqa ntawm cov qauv.
Xaus Lus: Kev Nqis Peev rau Kev Ua Kom Tseeb Mus Ntev
Thaum lub ntiaj teb kev tsim khoom txav mus rau Kev Lag Luam 4.0 thiab dhau mus, qhov kev thov rau "Kev Pov Hwm Zoo Tam Sim No" tab tom nce siab heev. Txawm tias koj tab tom kho qhov sib piv optical lossis teeb tsa lub CMM ntau-axis tshiab, lub hauv paus uas koj xaiv hnub no yuav txiav txim siab koj cov nqi tsis lees paub rau nees nkaum xyoo tom ntej.
Kev ua kom raug tsis yog ib qho xwm txheej; nws yog ib qho kev xaiv ua haujlwm engineering uas txhob txwm ua. Los ntawm kev xaiv cov khoom granite uas ruaj khov thiab cov thev naus laus zis siab heev, koj tsis yog yuav lub hauv paus tshuab xwb - koj tab tom ua kom koj lub npe nrov rau qhov zoo.
