Kev Txij Nkawm Qhov Tseeb thiab Kev Tshawb Fawb Txog Khoom Siv: Phau Ntawv Qhia Txog Kev Ncaj Ncees ntawm Cov Phaj Nto thiab Kev Xaiv Lub Hauv Paus Tshuab

Hauv kev lag luam tsim khoom uas muaj kev ntsuas siab heev, "datum" yog qhov tseem ceeb tshaj plaws ntawm txhua txoj kev tswj xyuas zoo. Txawm hais tias koj siv lub tshuab ntsuas Coordinate uas nyuaj lossis ua qhov kev tshuaj xyuas qhov siab ntawm tes, koj cov txiaj ntsig raug khi rau qhov tseeb ntawm koj lub hauv paus. Txawm li cas los xij, kev tswj qhov tseeb ntawd yuav tsum muaj kev nkag siab zoo txog kev saib xyuas cov khoom siv ntsuas thiab cov khoom siv lub cev ntawm cov ntaub ntawv koom nrog.

Ntawm ZHHIMG, peb feem ntau sab laj nrog cov neeg koom tes thoob ntiaj teb txog kev saib xyuas zoo tshaj plaws ntawm lawv cov chaw siv thiab cov kev xaiv qauv rau lawv cov tshuab tsim tom ntej. Tsab xov xwm no muab kev saib xyuas tag nrho ntawm qhov sib txawv tseem ceeb ntawm kev sim thiab kev ntsuas, lub luag haujlwm ntawm NDT, thiab kev sib cav sib ceg tas mus li ntawm granite piv rau hlau.

Kev Ntsuas vs. Kev Ntsuas: Nkag Siab Txog Lub Neej ntawm Granite Surface Plate

Hauv ntau phau ntawv qhia zoo, cov lus cog tsegkev kuaj xyuas granite nto phajthiab granite nto phaj calibration siv sib pauv tau. Rau ib tug kws tshaj lij metrology, txawm li cas los xij, lawv sawv cev rau ob theem sib txawv ntawm kev txheeb xyuas.

Kev Ntsuas Phaj Nto yog dab tsi?

Kev kuaj xyuas feem ntau yog theem pib lossis "kev kuaj xyuas qhov chaw". Nws suav nrog kev txheeb xyuas ib qho tshwj xeeb - feem ntau yog qhov tiaj tiaj hauv zos lossis qhov tseeb ntawm kev nyeem rov qab - siv lub ntsuas nyeem rov qab. Lub hom phiaj ntawm kev kuaj xyuas yog los teb cov lus nug binary:Puas yog lub phaj no tseem nyob hauv nws qhov kev kam rau siab (piv txwv li, Qib 00)?Nws yog ib qho cuab yeej kuaj mob siv ntawm lub sijhawm ua haujlwm raws cai kom ntseeg tau tias cov qauv hnav tsis tau cuam tshuam rau thaj chaw ua haujlwm tam sim ntawd.

Kev Kho Kom Zoo ntawm Cov Phaj Nto yog dab tsi?

Kev kho kom raug yog ib qho txheej txheem uas ua tiav thiab sau tseg uas ua kom lub phaj sib dhos nrog cov qauv thoob ntiaj teb (xws li ISO 8512-2 lossis ASME B89.3.7).Kev kho qhov chaw ntawm granite nto phajsiv cov txheej txheem ntsuas qhov chaw siv cov qib hluav taws xob siab lossis cov laser interferometers los kos duab tag nrho saum npoo av. Cov txheej txheem no ua rau muaj "daim ntawv qhia topographical" ntawm lub phaj, txheeb xyuas cov chaw siab thiab qis. Kev kho kom raug tsis yog tsuas yog xyuas qhov tseeb xwb; nws ntsuas qhov sib txawv thiab muab qhov kev taug qab uas xav tau rau cov chaw tau ntawv pov thawj ISO.

ZHHIMG Kev Nkag Siab: Txawm hais tias kev sim pom kev hnav txhua hnub, kev kho kom raug ua kom ntseeg tau tias muaj kev taug qab mus ntev. Yog tias koj qhov kev sim tsis ua tiav, koj kauj ruam tom ntej yog kev kho kom raug ua raws li kev rov ua dua tshiab (lapping).

Cov Txheej Txheem Kev Ntsuas Tsis Ua Rau Puas Tsuaj (NDT) rau Cov Khoom Siv Metrology

Yuav kom tswj tau cov qauv siab uas xav tau rau cov khoom siv ntsuas, cov chaw tsim khoom yuav tsum xyuas kom meej tias cov qauv sab hauv ntawm lawv lub hauv paus tsis muaj qhov tsis zoo yam tsis ua rau cov nplaim tiav lawm puas tsuaj. Qhov no yog qhov uas cov txheej txheem NDT rau kev ntsuas los ua si.

1. Kev Ntsuas Ultrasonic (UT): Feem ntau siv raugranite tshuab puagtxhawm rau nrhiav pom cov kab nrib pleb sab hauv lossis qhov tsis sib xws ntawm qhov ceev uas yuav ua rau muaj kev tsis ruaj khov ntawm qhov ntev dhau sijhawm.

2. Kev Tshuaj Xyuas Pom Kev Siv Cov Khoom Siv Kho Qhov Muag: Siv cov khoom sib piv pom kev loj lossis cov tshuab microscopes digital los tshuaj xyuas cov qauv crystalline ntawm granite rau cov cim ntawm "pitting" lossis thermal micro-cracking.

3. Kev Tshuaj Xyuas Cov Tshuaj Pleev Xim: Qee zaum siv rau ntawm cov tshuab ua los ntawm hlau cam khwb cia lossis cov qauv hlau kom pom cov kab nrib pleb uas tawg ntawm qhov chaw uas tsis pom ntawm lub qhov muag liab qab.

4. Kev Tso Tawm Suab: Ib txoj kev zoo heev los saib xyuas "kev ntxhov siab" hauv lub tshuab loj thaum lub sijhawm ua haujlwm ceev ceev, xyuas kom meej tias lub rooj cais kev co thiab lub hauv paus ua haujlwm raws li tau tsim.

Kev Ua Rog Khoom Siv: Granite vs. Steel Machine Bases

Thaum tsim lub hauv paus ntawm cov cuab yeej ua haujlwm siab, qhov kev xaiv ntawm lub hauv paus tshuab granite lossis steel feem ntau yog kev pauv pauv ntawm qhov ceev, tus nqi, thiab kev ruaj khov kiag li.

Cov Ntaub Ntawv rau Granite

Granite tseem yog tus yeej tsis muaj kev sib cav rau metrology vim nws qhov kev ruaj khov.

• Thermal Inertia: Granite qeeb qeeb teb rau qhov kub thiab txias hloov pauv. Tsis zoo li hlau, uas nthuav dav sai sai thaum tus kws kho tshuab sawv ze dhau lossis lub hnub ci ntsa iab rau lub tshuab, granite tseem khaws nws cov geometry.

• Kev Tiv Thaiv Kev Cob Qhia: Pob zeb ntuj muaj qhov piv ntawm kev tiv thaiv zoo dua. Nws nqus cov "kev sib tham" ntau zaus ntawm cov motors thiab actuators, uas yog qhov tseem ceeb rau lub tshuab ntsuas Coordinate kom ua tiav qhov tsis paub meej sub-micron.

Cov Ntaub Ntawv rau Hlau

Hlau feem ntau raug xaiv rau nws cov modulus ntawm elasticity thiab yooj yim ntawm kev tsim khoom.

• Kev Sib Koom Ua Ke: Cov hauv paus hlau tuaj yeem vuam thiab hloov kho tau yooj yim dua li pob zeb. Lawv feem ntau sib dua rau tib qhov ntim, uas yog ib qho ua rau cov tshuab uas yuav tsum tau tsiv chaw ntau zaus.

• Qhov Tsis Zoo: Hlau xav tau kev them nyiaj rau kev loj hlob ntawm thermal thiab feem ntau yuav tsum tau ntim nrog cov khoom sib xyaw ua ke lossis cov pob zeb ua kom phim cov khoom siv damping ntawm cov khoom khov.granite tshuab puag.

Kev Sib Koom Ua Ib Lub Ecosystem: Los Ntawm Cov Phaj Nto Mus Rau Cov Rooj Sib Cais

Ib lub phaj nto uas raug ntsuas tsuas yog zoo li hauv pem teb uas nws zaum rau xwb. Hauv cov chaw niaj hnub no, peb pom kev hloov mus rau cov txheej txheem sib xyaw ua ke. Ib lub phaj granite zoo feem ntau raug teeb tsa rau ntawm lub rooj cais kev co kom tiv thaiv nws ntawm kev cuam tshuam los ntawm av qeeg. Txoj hauv kev "nested" no kom ruaj khov ua kom ntseeg tau tias cov khoom siv ntsuas tuaj yeem ua haujlwm ntawm nws qhov kev txwv theoretical, tsis hais txog kev ua haujlwm hauv lwm qhov ntawm lub Hoobkas.

Ntawm ZHHIMG, peb tsis yog tsuas yog muab cov granite xwb; peb muab kev txawj ntse engineering los koom ua ke cov ntaub ntawv no rau hauv koj cov haujlwm tshwj xeeb. Txawm hais tias koj tab tom calibrate lub phaj qub lossis tsim lub kaw lus ntsuas 5-axis tshiab, kev nkag siab txog kev sib cuam tshuam ntawm cov ntaub ntawv no thiab cov txheej txheem txij nkawm yog qhov tseem ceeb.

Xaus Lus: Kev Ruaj Ntseg Rau Koj Lub Neej Yav Tom Ntej Kev Ntsuas

Qhov tseeb ntawm koj cov khoom pib nrog qhov ruaj khov ntawm koj cov ntaub ntawv. Los ntawm kev sib txawv ntawm kev sim granite nto phaj thiab kev ntsuas raws cai, thiab los ntawm kev xaiv qhov ruaj khov ntawm ibgranite tshuab puagdhau hlau rau cov ntawv thov tseem ceeb, koj tab tom nqis peev rau lub neej ntev ntawm koj qhov kev pab cuam zoo.

Kev ua kom raug yog ib txoj kev taug kev ntawm kev txheeb xyuas tas li. Thaum cov txheej txheem NDT yooj yim nkag tau yooj yim dua thiab kev tshawb fawb txog cov khoom siv tau nce qib, ZHHIMG tseem nyob rau pem hauv ntej, kom ntseeg tau tias koj qhov "xoom" tseem nyob qhov twg nws yuav tsum nyob.
