Hauv qhov chaw muaj kev pheej hmoo siab ntawm kev tsim kho niaj hnub no, qhov tseeb ntawm koj cov cuab yeej ntsuas tseem ceeb tuaj yeem ua rau cov khoom ua raws li qhov yuav tsum tau ua lossis tsis ua. Txawm hais tias qhov chaw tiaj tiaj zoo li yooj yim, kev lag luam kev lees paub zoo vam khom cov cuab yeej uas tau ntawv pov thawj, ua tib zoo, tsis muaj qhov tseem ceeb dua li lub phaj granite. Rau cov kws tshaj lij uas xav tau qhov zoo tshaj plaws, nkag siab txog qhov sib txawv ntawm qhov tseeb, lub luag haujlwm ntawm cov chaw tsim khoom tau ntawv pov thawj zoo li ZHHIMG granite phaj, thiab qhov tsim nyog ntawm kev txhawb nqa kom zoo tsis yog tsuas yog kev coj ua zoo xwb - nws yog qhov tseem ceeb ntawm kev lag luam.
Tshaj Qhov Smoothness: Kev Txhais Cov Qib Tseeb ntawm Granite Plate
Thaum nrhiav ib lub hauv paus ntsuas, cov engineers yuav tsum saib dhau cov khoom siv thiab tsom mus rau qhov kam rau siab uas tau ua tiav thaum lub sijhawm tseem ceeb. Qhov kam rau siab no txhais tau tias qib, ib daim ntawv pov thawj ntawm seb lub phaj lo rau lub dav hlau zoo meej, theoretical. Kev lag luam siv cov txheej txheem meej, qhov twg qhov kam rau siab nruj dua sib raug rau cov qib tshwj xeeb, feem ntau ua raws li cov qauv zoo li Federal Specification GGG-P-463c lossis DIN 876. Lub siab tshaj plaws ntawm kev raug yog sawv cev los ntawm qib AA granite nto phaj (qee zaum hu ua Qib 00). Cov phaj no muab qhov sib txawv qis tshaj plaws hauv kev tiaj tiaj thoob plaws tag nrho nto. Lawv yog cov qauv ntsuas, feem ntau siv hauv cov chaw soj nstuam tswj hwm ib puag ncig rau kev ntsuas thawj zaug ntawm cov cuab yeej siab tshaj plaws. Yog tias koj txoj haujlwm cuam tshuam nrog kev lees paub cov qauv siv lossis thawb cov kev txwv ntawm kev ntsuas qhov ntev, Qib AA yog tib qho kev xaiv uas tau txais.
Txo me ntsis, tab sis tseem nyob hauv qhov tseeb tshaj plaws, peb pom qib 0 granite nto phaj (lossis Qib A). Qib no yog lub hauv paus ntawm cov chav tshuaj xyuas zoo tshaj plaws thiab cov chaw tswj xyuas zoo tshaj plaws. Nws muab qhov tiaj tiaj zoo tshaj plaws uas xav tau rau kev ntsuas cov khoom siv ntsuas siab, ua cov haujlwm teeb tsa tseem ceeb, thiab tshuaj xyuas cov khoom nrog qhov kam rau siab tshaj plaws. Qhov sib txawv ntawm qhov tiaj tiaj tag nrho ntawm Qib AA thiab Qib 0 yog ntsuas tau, tab sis rau feem ntau kev ntsuas qib thib ob thiab kev tshuaj xyuas qib siab, Qib 0 muab qhov sib npaug zoo ntawm kev ua tau zoo thiab kev siv tau. Txawm hais tias cov qauv siv thoob ntiaj teb, qhov sib xws ntawm kev ua tiav cov qib no nyob ntawm tus neeg tsim khoom kev txawj ntse, cov khoom siv, thiab cov khoom siv. Cov tuam txhab zoo li ZHHIMG txawv lawv tus kheej los ntawm kev ua raws li cov qauv thoob ntiaj teb no, xyuas kom meej tias thaum koj yuav Qib AA lossis Qib 0 phaj, qhov tsis paub meej tau sau tseg yog qhov ntseeg tau thiab taug qab tau. Rau cov neeg yuav khoom uas tau siv rau cov npe paub, qhov zoo yuav tsum sib tw lossis dhau qhov kev ua tau zoo uas xav tau los ntawm cov chav tsev zoo, xws li grizzly granite nto phaj, los ntawm kev tswj hwm nruj rau tag nrho cov txheej txheem tsim khoom thiab ua tiav.
Tus phab ej uas tsis tau muaj leej twg hu: Lub Rooj Muag Phaj Granite
Ib qho yuam kev uas feem ntau tshwm sim hauv kev teeb tsa metrology yog tsom mus rau qib ntawm lub phaj xwb thaum tsis quav ntsej txog nws txoj kev txhawb nqa. Lub phaj Qib AA uas muab tso rau ntawm lub hauv paus tsis zoo lossis tsim tsis zoo, qhov ua haujlwm, tsis zoo dua li lub phaj qib qis dua. Cov qauv txhawb nqa qhov hnyav ntawm granite yuav tsum tiv thaiv kev khoov, cais kev co, thiab tso cai rau lub phaj kom xav tias nws tiaj tiaj. Qhov no yog qhov uas lub phaj granite tshwj xeeb sawv ntsug ua ib qho khoom tseem ceeb.
Cov rooj sawv ntsug no tau tsim tshwj xeeb los txhawb lub phaj ntawm nws cov Airy Points lossis Bessel Points uas tau suav lej. Cov ntsiab lus no yog qhov chaw zoo tshaj plaws los txo qhov kev hloov pauv thiab kev cuam tshuam ntawm lub phaj tag nrho vim nws qhov hnyav. Lub rooj dav dav yuav tsis faib qhov hnyav loj no kom raug, ua rau muaj qhov yuam kev ntsuas tau rau hauv lub dav hlau siv. Ntxiv mus, cov rooj sawv ntsug zoo feem ntau muaj cov khoom siv tiv thaiv kev co lossis cov taw qhia theem, uas pab cais lub phaj rhiab heev ntawm kev co hauv pem teb los ntawm cov tshuab nyob ze, kev taug kev, lossis HVAC systems. Qhov no yog qhov tseem ceeb tshwj xeeb rau Qib AA thiab Qib 0 phaj qhov twg micro-vibrations tuaj yeem ua rau kev ntsuas tseem ceeb puas tsuaj. Thaum kawg, lub rooj sawv ntsug granite zoo muaj cov jacks leveling uas tso cai rau tus neeg siv kom ncaj qha theem lub phaj. Thaum lub ntiajteb txawj nqus ua kom lub phaj saum npoo yog "tiaj tus" hauv nws lub dav hlau siv, kev sib npaug yog qhov tsim nyog rau kev siv cov qib npuas, cov qib hluav taws xob, thiab cov khoom siv ntsuas tshwj xeeb (xws li cov ntsuas kem) uas vam khom qhov siv ntsug lossis kab rov tav rau lub dav hlau siv. Kev yuav lub phaj Qib 0 los ntawm tus neeg muag khoom muaj npe zoo li ZHHIMG yam tsis muaj lub rooj sawv ntsug yog lub sijhawm tsis nco qab. Qhov kev nqis peev rau hauv lub phaj qhov kev ua kom raug yuav raug cuam tshuam yog tias cov qauv txhawb nqa ua rau muaj kev cuam tshuam uas tshaj qhov kev kam rau siab ntawm lub phaj.
Cov Ntaub Ntawv rau Cov Granite Dub Uas Muaj Ntawv Pov Thawj
Txawm hais tias siv ntau hom granite, cov phaj tseeb tshaj plaws - tshwj xeeb tshaj yog cov uas ncav cuag qib AA granite nto phaj qauv - feem ntau yog ua los ntawm granite dub (xws li dub Diabase lossis Impala Dub). Cov khoom siv no tsis yog tsuas yog xaiv rau nws qhov zoo nkauj xwb tab sis rau nws cov yam ntxwv zoo tshaj plaws. Granite dub feem ntau qhia txog qhov porosity qis dua, txhais tau tias nws nqus cov av noo tsawg dua, thiab qhov kev ruaj khov ntawm qhov ntev no yog qhov tseem ceeb hauv kev tswj hwm qhov tseeb ntawm qib hla ntau qib av noo. Nws kuj tseem denser thiab muaj Modulus ntawm Elasticity siab dua li granites sib dua, uas pab lub phaj tiv taus deflection nyob rau hauv qhov hnyav ntawm cov khoom siv ntsuas thiab qhov chaw. Qhov tseem ceeb, qhov coefficient ntawm thermal expansion (CTE) yog qis heev. Qhov no txhais tau tias yog tias qhov kub hloov pauv hauv chav tshuaj xyuas, lub phaj granite hloov qhov ntev tsawg dua li lwm yam khoom siv, khaws cia lub dav hlau siv qhov tseeb. Thaum koj xaiv cov khoom zoo li ZHHIMG granite nto phaj, koj tab tom yuav rau hauv tag nrho cov khoom siv science pob, uas suav nrog cov khoom zoo tshaj plaws ntawm granite nws tus kheej, ua ke nrog kev tshaj lij lapping.
Kev Txij Nkawm thiab Lub Neej Siv Tau: Khaws Koj Cov Nyiaj Txiag
Lub neej ntev ntawm qib 0 granite nto phaj lossis lwm yam cuab yeej siab precision nyob ntawm nws txoj kev saib xyuas. Kev tsis saib xyuas tuaj yeem ua rau nws qhov tseeb poob qis sai sai, ua rau Qib 0 hloov mus rau Qib 1 lossis phem dua, thiab yuav tsum tau rov kho dua lossis rov ua dua. Kev saib xyuas tas li qhia tias ib tus neeg yuav tsum tsis txhob siv cov tshuaj ntxuav hauv tsev lossis cov khoom siv abrasive; cov tshuaj ntxuav phaj nto tshwj xeeb tau tsim los tshem tawm cov roj, plua plav, thiab cov khoom me me yam tsis ua rau puas tsuaj rau saum npoo. Qhov tseeb, plua plav thiab xuab zeb yog cov ua rau hnav hauv zos. Ntxiv mus, cov txheej txheem thauj khoom kom zoo yuav tsum tso cov khoom ua haujlwm maj mam, tsis txhob swb lossis rub cov khoom hnyav lossis ntxhib hla granite, vim tias qhov kev ua no ua rau qhov chaw hnav dhau sijhawm. Kev ua raws li lub sijhawm calibration nruj (feem ntau 6 txog 12 lub hlis rau cov phaj qib siab hauv kev siv hnyav) tsis tuaj yeem sib tham tau. Calibration ua kom ntseeg tau tias lub phaj qhov tiaj tiaj tseem nyob hauv nws qhov kev lees paub thiab muab cov ntaub ntawv raug cai ntawm nws qhov tseeb. Thaum kawg, kev nqis peev rau hauv lub hauv paus zoo - txawm tias yog qib AA granite nto phaj rau lub chaw kuaj lossis kev teeb tsa ruaj khov uas muaj ZHHIMG granite nto phaj ntawm lub granite nto phaj tshwj xeeb - yog ib qho pov thawj rau lub tuam txhab txoj kev cog lus rau qhov zoo. Qhov sib txawv ntawm kev ntsuas qhov tseeb thiab qhov tsis ua haujlwm feem ntau los txog rau qhov kev ncaj ncees ntawm ib qho khoom siv no, ntsiag to, thiab tseem ceeb.
