Hauv kev lag luam tsim khoom uas muaj kev ntsuas siab heev, qhov xav tau cov cuab yeej siv ruaj khov, txhim khu kev qha, thiab raug heev yeej tsis tau muaj dua li no. Txawm hais tias cov tshuab ntsuas digital tau nrov heev, qhov ua tiav ntawm txhua qhov kev sib dhos siab-txij li cov khoom siv semiconductor mus rau cov tshuab CNC siab heev-tseem nyob ntawm qhov kev ua tiav ntawm nws cov ntsiab lus siv lub cev. Ntawm cov no, tus kav granite square sawv tawm ua lub cuab yeej tseem ceeb, tab sis tsuas yog thaum nws ua tiav daim ntawv pov thawj siab tshaj plaws: DIN 00.
Kev ua tiav qib DIN 00 tsis yog tsuas yog ib qho kev ua raws li txoj cai xwb; nws qhia txog qib kev ua tiav ntawm geometric uas txhais tau ncaj qha mus rau hauv kev ua haujlwm, kev txheeb xyuas qhov tseeb ntawm pem teb tsim khoom. Qib kev ua tiav no yog lub hauv paus ntawm kev sib dhos thiab kev tswj xyuas cov khoom siv niaj hnub no, ua haujlwm ua qhov tseem ceeb "master square" rau kev txheeb xyuas cov qauv tshuab, kuaj xyuas qhov perpendicularity ntawm CMM axes, thiab xyuas kom meej tias qhov sib npaug ntawm cov kab ke linear.
Qhov Tseem Ceeb ntawm DIN 00: Txhais Kev Zoo Tag Nrho Geometric
Tus qauv Deutsche Industrie Norm (DIN) 875 txhais meej txog qhov kev hloov pauv uas tso cai rau kev tiaj tus, kev ncaj, thiab kev sib npaug hauv cov cuab yeej ntsuas qhov tseeb. DIN 00 sawv cev rau qhov siab tshaj plaws ntawm kev faib tawm no, "qib calibration," tshwj tseg rau cov cuab yeej siv hauv cov chaw kuaj calibration rhiab heev tshaj plaws thiab ua cov tswv rau kev kuaj xyuas lwm yam cuab yeej.
Rau ib qho lojgranite square ntsuasYuav kom dais tau lub cim DIN 00, nws cov ntsej muag tseem ceeb yuav tsum ua kom pom tseeb tias yuav luag zoo meej perpendicularity thiab ncaj, nrog rau kev kam rau siab heev rau kev hloov pauv thoob plaws nws qhov ntev. Qib kev raug no yog qhov tseem ceeb vim tias txhua qhov yuam kev angular hauv tus pas ntsuas yog sib xyaw thaum siv los kho cov tshuab loj dua lossis cov dav hlau siv. Yog tias tus pas ntsuas tsis yog square zoo meej, lub cuab yeej tshuab uas teeb tsa tawm tsam nws yuav nqa qhov yuam kev ntawd, ua rau muaj qhov tsis raug ntawm qhov ntev hauv qhov kawg tsim.
Kev Cai Khoom Siv: Vim Li Cas Granite Zoo Tshaj Plaws Qhov Twg Hlau Ua Tsis Tau Zoo
Kev xaiv cov khoom siv yog thawj kauj ruam tseem ceeb rau kev ua tiav DIN 00 qhov tseeb. Txawm hais tias cov hlau squares yog cov khoom siv ntau, lawv tsis haum rau qhov chaw ua haujlwm dynamic, high-precision ntawm kev tsim khoom niaj hnub vim lawv qhov kev cuam tshuam rau thermal expansion thiab corrosion.
Cov granite zoo, tshwj xeeb yog cov gabbro dub tuab zoo li cov khoom siv ZHHIMG® (qhov ceev ≈3100 kg/m³), muaj peb qhov zoo tseem ceeb uas ua rau tus kav granite square zoo dua rau kev ruaj khov:
-
Kev Nthuav Dav Thermal Qis: Granite muaj cov coefficient ntawm kev nthuav dav thermal uas qis heev - qis dua li hlau. Hauv ib puag ncig uas tswj tau qhov kub thiab txias, qhov no ua kom ntseeg tau tias tus pas ntsuas geometry tseem tsis hloov pauv, tswj nws daim ntawv pov thawj DIN 00 yam tsis muaj kev pheej hmoo ntawm kev nthuav dav ua rau muaj qhov yuam kev.
-
Kev Ruaj Khoov Zoo Tshaj Plaws thiab Kev Tiv Thaiv: Lub modulus siab ntawm elasticity uas muaj nyob rau hauv cov pob zeb dub zoo tshaj plaws muab kev ruaj khov zoo heev. Qhov kev ruaj khov no txo qhov kev hloov pauv thaum tus pas ntsuas raug tswj lossis muab tso rau hauv qab kev thauj khoom. Ntxiv mus, nws cov qauv ntuj tsim tau zoo txo qhov kev co, ib qho khoom tseem ceeb thaum tus pas ntsuas siv ua ke nrog cov cuab yeej ntsuas rhiab heev ntawm lub khw hauv pem teb.
-
Tsis Muaj Hlau Npib Thiab Tiv Thaiv Kev Xeb: Granite tsis xeb lossis xav tau cov txheej tiv thaiv, ua kom nws cov ntsej muag ua haujlwm tseem huv thiab ruaj khov geometrically dhau ntau xyoo ntawm kev siv. Qhov no tshem tawm qhov tsis paub meej uas tau tshwm sim los ntawm kev cuam tshuam magnetic hauv kev kuaj xyuas kev sib phim uas muaj cov khoom siv electromagnetic.
Cov Yeeb Nkab Ua Haujlwm Precision Engineering: Los ntawm Pob Zeb mus rau Txheem
Ua tiav qib DIN 00 ntawm ib qhogranite square ntsuasyog ib qho txheej txheem tsim khoom uas nyuaj thiab muaj ntau theem uas sib xyaw cov thev naus laus zis siab heev nrog kev txawj ua tes ua taw uas tsis muaj qhov hloov pauv tau. Nws pib nrog kev xaiv cov pob zeb granite sab hauv uas tsis muaj kev ntxhov siab thiab mus txog kev sib tsoo tsis zoo, kev laus uas txo kev ntxhov siab, thiab cov txheej txheem lapping ntau theem.
Cov theem kawg, tseem ceeb ntawm kev kho qhov geometry feem ntau ua nyob rau hauv cov chaw soj nstuam uas tswj hwm huab cua, qhov twg qhov kub thiab av noo raug tswj hwm kom tshem tawm cov yam ntxwv ib puag ncig. Ntawm no, cov kws tshaj lij metrology siv cov khoom siv ntsuas zoo heev - suav nrog autocollimators, laser trackers, thiab electronic levels - los xyuas qhov perpendicularity thiab ncaj ntawm tus pas ntsuas lub ntsej muag. Cov kev hloov kho zaum kawg yog ua los ntawm kev sib tsoo tes. Cov kws txawj ua haujlwm no, qee zaum hu ua "walking electronic levels," muaj kev paub txog kev kov kom tshem tawm cov khoom ntawm qib sub-micron, coj tus pas ntsuas kom ua raws li qhov kev kam rau me me uas xav tau los ntawm DIN 00.
Qhov tseeb ntawm cov khoom kawg tsuas yog lav los ntawm kev ntsuas kom zoo thiab taug qab tau. Txhua tus pas ntsuas granite zoo yuav tsum tau txheeb xyuas siv cov cuab yeej uas taug qab mus rau lub koom haum ntsuas hauv tebchaws. Qhov no ua kom ntseeg tau tias cov cuab yeej tsis yog tsuas yog raug xwb tab sis kuj raug txheeb xyuas raws li tus qauv thoob ntiaj teb, pom zoo.
Tshaj Lij Chav Kuaj: Cov Kev Siv ntawm DIN 00 Granite Square
Qhov kev thov rau tus kav granite square nrog daim ntawv pov thawj DIN 00 qhia txog nws lub luag haujlwm tseem ceeb thoob plaws kev lag luam siab:
-
Kev Sib Tov Khoom Siv Tshuab: Siv los xyuas qhov sib npaug ntawm cov axes ntawm cov cuab yeej siv tshuab (XY, YZ, XZ) tom qab kev teeb tsa lossis kev saib xyuas, kom ntseeg tau tias lub tshuab qhov tseeb geometric tseem khaws cia rau kev tsim cov khoom ua haujlwm siab.
-
Kev Txheeb Xyuas CMM: Ua tus thawj coj siv los ntsuas thiab txheeb xyuas qhov system probe thiab kev txav mus los ntawm cov tshuab ntsuas sib koom ua ke, uas yog cov cuab yeej tswj xyuas zoo tshaj plaws.
-
Kev Sib Dhos Cov Theem Uas Muaj Kev Ntsuas Tseeb: Siv rau hauv kev sib dhos thiab kev sib dhos ntawm cov theem txav mus los thiab cov tshuab cua uas siv dav hauv cov khoom siv semiconductor thiab kev tsim cov zaub tiaj tiaj, qhov twg qhov kev sib dhos meej yog qhov tseem ceeb rau kev ua haujlwm zoo.
-
Kev Sib Tov Optical: Muab ib lub dav hlau uas muaj plaub fab tiag tiag rau kev sib txuas cov khoom siv optical breadboards thiab laser systems uas qhov kev ruaj khov ntawm lub kaum sab xis yog qhov tseem ceeb rau kev ncaj ncees ntawm txoj kab teeb.
Qhov ua tau ntev thiab ruaj khov ntawm tus pas ntsuas granite square nrog DIN 00 ua rau nws yog ib qho khoom muaj nqis tseem ceeb, mus sij hawm ntev hauv txhua lub chaw tsim khoom lossis chaw kuaj ntsuas siab heev. Nws sawv cev rau kev nqis peev tsis yog rau hauv ib lub cuab yeej xwb, tab sis rau hauv lub hauv paus tseeb, meej ntawm qhov tseeb ntawm qhov ntev uas txhua qhov kev ntsuas thiab kev sib dhos tom qab ntawd nyob ntawm. Rau cov chaw tsim khoom uas siv zog rau qhov tseeb tiag tiag, txhua yam tsawg dua DIN 00 tsuas yog ua rau muaj kev pheej hmoo tsis zoo.
