Hauv lub ntiaj teb kev ntsuas thiab kev ua haujlwm precision, qhov tseeb ntawm koj lub hauv paus ntsuas yog qhov tseem ceeb heev. Txhua lub micrometer tseem ceeb, thiab lub cuab yeej uas muaj lub luag haujlwm los muab qhov chaw siv tau zoo tshaj plaws yog lub phaj granite. Rau cov neeg ua haujlwm ntawm qib siab tshaj plaws ntawm kev tsim khoom, kev ntsuas, thiab kev tswj xyuas zoo, qhov kev xaiv tsis yog tsuas yog xaiv granite xwb; nws yog hais txog kev ua raws li cov qauv thoob ntiaj teb uas tau teev tseg los ntawm daim ntawv qhia qib phaj granite.
Qhov kev ua yooj yim uas zoo li muab lub cuab yeej ntsuas tso rau ntawm ib qho chaw tiaj tiaj tsis yog qhov nyuaj ntawm kev tshawb fawb txog cov khoom siv thiab kev tsim kho uas siv rau hauv kev tsim lub phaj saum npoo uas ua tau zoo. Feem ntau, kev lag luam lees paub ntau qhov kev faib tawm qhov tseeb, feem ntau ua raws li cov lus qhia uas tau teeb tsa los ntawm cov qauv xws li Federal Specification GGG-P-463c (Tebchaws Meskas) lossis DIN 876 (German). Kev nkag siab txog qhov system grading no yog qhov tseem ceeb rau txhua tus thawj tswj kev yuav khoom, tus kws tshaj lij kev lees paub zoo, lossis tus kws tsim qauv.
Qhov Txawv Tseem Ceeb: Nkag Siab Txog Cov Qib Granite Surface Table
Thaum peb tham txog lub rooj granite nto qib 0 lossis qib A granite nto phaj, peb tab tom hais txog qhov kev hloov pauv uas tso cai los ntawm qhov tiaj tiaj zoo meej thoob plaws thaj chaw ua haujlwm. Qhov no hu ua kev kam rau siab rau qhov tiaj tiaj tag nrho. Cov qib tsim kom muaj qib siab ntawm qhov tseeb, ncaj qha cuam tshuam nrog cov ntawv thov uas lawv haum rau.
-
Qib Kuaj Mob (feem ntau Qib AA lossis Qib 00): Qhov no sawv cev rau qhov siab tshaj plaws ntawm kev raug. Cov phaj hauv qib no muaj qhov kev kam rau siab tshaj plaws thiab feem ntau yog tseg rau cov ntawv thov uas xav tau tshaj plaws, xws li cov chaw kuaj mob thawj zaug uas kev tswj hwm ib puag ncig yog qhov tseeb thiab kev ntsuas tau teeb tsa tus qauv rau lwm tus. Tus nqi thiab kev saib xyuas zoo uas xav tau qhia txog lawv qhov tseeb tsis muaj qhov sib piv.
-
Qib Tshuaj Xyuas (feem ntau Qib A lossis Qib 0): Qhov no yog qhov ua haujlwm ntawm feem ntau cov chaw tswj xyuas zoo thiab chav tshuaj xyuas. Lub rooj granite nto qib 0 muaj qhov tiaj tiaj zoo heev, ua rau nws zoo tagnrho rau kev tshuaj xyuas tseem ceeb ntawm cov khoom muaj qhov tseeb siab thiab rau kev ntsuas cov ntsuas, micrometers, thiab lwm yam khoom siv ntsuas. Qhov kam rau siab rau qib no feem ntau yog ob npaug ntawm Qib Kuaj Mob, muab qhov sib npaug zoo ntawm qhov tseeb thiab kev siv tau.
-
Qib Chav Cuab Yeej (feem ntau Qib B lossis Qib 1): Lub phaj granite nto qib 1 yog qhov feem ntau thiab siv tau ntau yam. Nws qhov kev kam rau siab yog qhov tsim nyog rau kev tswj xyuas zoo dav dav, kev tshuaj xyuas hauv pem teb, thiab kev siv ntau lawm qhov twg tseem xav tau qhov tseeb siab, tab sis qhov tseeb siab ntawm Qib 0 yog overkill. Nws muab lub dav hlau tiaj tiaj tseem ceeb uas xav tau rau kev teeb tsa cov cuab yeej, kev teeb tsa ua haujlwm, thiab ua cov kev kuaj xyuas qhov ntev ib txwm nyob ib sab ntawm cov chaw machining.
-
Qib Hauv Pem Teb (feem ntau yog Qib 2 lossis Qib B): Txawm hais tias tseem yog ib qho cuab yeej ntsuas qhov tseeb, qib no yog tsim los rau kev ntsuas tsis tseem ceeb, feem ntau siv rau kev ua haujlwm rougher lossis hauv cov chaw uas qhov kub hloov pauv ntau dua, thiab qhov tseeb tshaj plaws tsis raug yuam.
Tus yam ntxwv tseem ceeb uas ua rau lub phaj granite qib 1 txawv ntawm Qib 0 yog Tag Nrho Cov Ntawv Qhia Kev Nyeem (TIR) rau qhov tiaj tiaj. Piv txwv li, lub phaj 24 "x 36" Qib 0 yuav muaj qhov kam rau siab ntawm ib ncig ntawm 0.000075 ntiv tes, thaum Qib 1 ntawm tib qhov loj me yuav tso cai rau qhov kam rau siab ntawm 0.000150 ntiv tes. Qhov sib txawv no, txawm hais tias ntsuas hauv lab ntawm ib nti, yog qhov tseem ceeb hauv kev tsim khoom siab.
Vim li cas Granite? Qhov Zoo ntawm Kev Tshawb Fawb Txog Khoom Siv
Kev xaiv cov khoom siv tsis yog qhov tsis muaj laj thawj. Granite, tshwj xeeb tshaj yog cov granite dub (piv txwv li, Diabase) feem ntau siv rau cov phaj zoo tshaj plaws, raug xaiv rau ntau qhov laj thawj uas ua rau nws txoj haujlwm ruaj khov dua li lwm cov hlau:
-
Kev Ruaj Ntseg Thermal: Granite muaj qhov coefficient ntawm thermal expansion (CTE) qis heev. Tsis zoo li hlau, uas nthuav dav thiab cog lus ntau nrog kev hloov pauv kub, granite tswj nws qhov loj me nrog kev sib xws zoo kawg nkaus. Qhov no yog qhov tseem ceeb hauv qhov chaw ua haujlwm uas tsis tshua muaj kev tswj hwm kub zoo meej.
-
Kev Tiv Thaiv Kev Co: Cov pob zeb granite uas muaj cov yam ntxwv ntuj tsim muaj cov yam ntxwv zoo tshaj plaws rau kev tiv thaiv sab hauv. Nws nqus tau cov kev co ntawm lub tshuab thiab kev poob siab sab nraud zoo dua li hlau, uas pab kom lub kaw lus ntsuas ruaj khov dua thiab ua kom cov nyeem ntawv ruaj khov dua.
-
Kev Nyuaj Siab thiab Kev Hnav Tsis Taus: Granite nyuaj heev, feem ntau sau npe ntawm 6 thiab 7 ntawm Mohs nplai. Qhov no muab ib qho chaw hnav uas tsis yog tsuas yog ruaj khov heev xwb, tab sis, qhov tseem ceeb, txhua qhov hnav uas tshwm sim feem ntau yuav tshwm sim ua qhov chaw chipping es tsis yog qhov du distortion (dishing) feem ntau ntawm cov hlau, yog li khaws cia qhov tiaj tiaj tag nrho ntev dua.
-
Tsis Muaj Hlau Sib Nqus thiab Tsis Muaj Xeb: Granite tsis nkag mus rau hauv cov teb sib nqus thiab tsis xeb, tshem tawm ob qhov chaw tseem ceeb ntawm qhov yuam kev thiab kev ua qias tuaj yeem cuam tshuam rau kev teeb tsa ntsuas raws li hlau sib nqus thiab cov cuab yeej rhiab heev.
Xyuas kom muaj sia nyob ntev thiab tswj hwm qib
Qhov qib ntawm lub phaj nto tsis yog lub xeev ruaj khov; nws yuav tsum tau tswj hwm. Qhov kev ua kom raug yog nyob ntawm thawj qhov kev sib tsoo thiab kev txhuam hniav, qhov twg cov kws tshaj lij txawj ntse coj qhov chaw kom raug hauv qhov kev kam rau siab ntawm daim ntawv qhia qib phaj granite.
-
Kev Kho Kom Zoo: Kev kho kom zoo tsis tu ncua, uas tau ntawv pov thawj lawm tsis tuaj yeem sib tham tau. Qhov zaus nyob ntawm qib ntawm lub phaj, kev siv zog, thiab cov xwm txheej ib puag ncig. Lub phaj siv ntau, Qib Tshuaj Xyuas yuav xav tau kev kho kom zoo txhua rau txog kaum ob lub hlis.
-
Kev Huv Si: Cov hmoov av thiab cov khoom me me yog cov yeeb ncuab phem tshaj plaws ntawm lub phaj nto. Lawv ua haujlwm ua cov khoom me me uas ua rau hnav, thiab tsim cov qhov siab me me uas ua rau tsis du. Kev ntxuav kom huv si nrog cov tshuaj ntxuav phaj nto tshwj xeeb yog qhov tseem ceeb ua ntej thiab tom qab siv.
-
Siv Kom Zoo: Tsis txhob rub cov khoom hnyav hla qhov chaw. Siv lub phaj ua lub dav hlau siv, tsis yog lub rooj ua haujlwm. Faib cov khoom kom sib npaug, thiab xyuas kom lub phaj tau teeb tsa kom raug rau ntawm nws lub kaw lus txhawb nqa tshwj xeeb, uas tau tsim los tiv thaiv kev poob qis thiab tswj kom nws tiaj tus.
Lub Angle SEO: Kev Taw Qhia Txog Kev Paub Zoo
Rau cov lag luam uas ua haujlwm rau kev lag luam precision, kev paub txog cov lus hais txog granite nto phaj qib 1, granite nto rooj qib, thiab qib A granite nto phaj yog qhov tseem ceeb rau kev pom digital. Cov cav tshawb nrhiav muab qhov tseem ceeb rau cov ntsiab lus uas muaj cai, raug cai, thiab teb ncaj qha rau tus neeg siv lub hom phiaj. Ib tsab xov xwm tiav uas delves rau hauv 'vim li cas' tom qab qib, lub hauv paus kev tshawb fawb ntawm kev xaiv cov khoom siv, thiab cov txiaj ntsig zoo rau kev tswj hwm zoo tsis tsuas yog nyiam cov neeg siv khoom tab sis tsim kom muaj tus neeg muab kev pabcuam ua tus thawj coj kev xav hauv metrology.
Qhov chaw ua haujlwm niaj hnub thiab kev tsim khoom xav tau kev paub tseeb tiag tiag. Lub phaj granite tseem yog tus qauv kub rau kev ntsuas qhov ntev, thiab kev nkag siab txog nws txoj kev ntsuas qib yog thawj kauj ruam mus rau kev ua tiav qhov tseeb thiab kev ua tau zoo hauv ntiaj teb. Kev xaiv lub phaj zoo - txawm tias qhov tseeb ntawm lub rooj granite qib 0 lossis qhov tseeb ntawm Qib 1 - yog kev nqis peev uas them nyiaj rau kev lees paub zoo thiab txo qis kev ua haujlwm dua, xyuas kom meej tias txhua yam khoom uas tawm hauv koj lub chaw ua tau raws li cov lus qhia nruj tshaj plaws.
