Hauv ntiaj teb ntawm kev ntsuas thiab kev tshuaj xyuas siab, Lub Tshuab Ntsuas Sib Koom Tes (CMM) sawv cev rau qhov kev txiav txim siab kawg ntawm qhov zoo. Txawm li cas los xij, qhov tseeb ntawm CMM tsis yog tsuas yog ib qho haujlwm ntawm nws cov software lossis nws cov sensors; nws yog qhov tseem ceeb los ntawm lub hauv paus lub cev uas cov sensors txav mus rau. Tau ntau xyoo, cov engineers thiab cov kws tshaj lij kev yuav khoom tau ntsib kev sib cav sib ceg: puas yuav tsum tsim lub hauv paus tshuab los ntawm cov granite precision lossis cov hlau cam khwb cia ib txwm muaj?
Kev xaiv cov khoom siv zoo yog qhov kev txiav txim siab zoo uas cuam tshuam rau lub tshuab lub neej ntev, nws cov kev teb rau kev hloov pauv ib puag ncig, thiab thaum kawg, qhov kev ntseeg siab ntawm cov ntaub ntawv nws tsim tawm. Ob qho khoom siv tau pab rau kev lag luam tsim khoom ntau tshaj ib puas xyoo, tab sis lawv muaj cov cwj pwm sib txawv heev. Kev nkag siab txog qhov sib txawv ntawm ob "hnyav" no yog qhov tseem ceeb rau txhua qhov chaw uas tab tom nrhiav kev txhim kho lawv lub chaw soj ntsuam rau qhov xav tau ntawm kev tsim khoom niaj hnub.
Qhov Zoo ntawm Geological ntawm Precision Granite
Granite tau dhau los ua qhov kev xaiv tseem ceeb rau cov qauv CMM niaj hnub no, thiab rau qhov laj thawj zoo. Los ntawm qhov pom ntawm lub cev, granite dub yog ib qho ntawm cov khoom siv ruaj khov tshaj plaws pom muaj nyob rau hauv xwm. Nws lub zog tseem ceeb yog nyob rau hauv nws cov coefficient ntawm thermal expansion, uas qis dua li ntawm feem ntau cov hlau. Hauv qhov chaw uas qhov kub tsis tau tswj hwm zoo rau ib feem ntawm ib qib, lub hauv paus hlau yuav nthuav dav thiab cog lus, ua rau qhov ntsuas geometry mus rau drift. Granite tseem nyob twj ywm zoo kawg nkaus, ua kom ntseeg tau tias "zero point" nyob twj ywm qhov chaw nws nyob.
Tshaj li qhov ruaj khov thermal, granite yog inherently xeb-resistant thiab acid-resistant. Hauv ntau qhov chaw ua lag luam, cov dej noo lossis cov pa tshuaj tuaj yeem ua rau oxidation ntawm cov hlau nto. Thaum cov hlau cam khwb cia xav tau cov roj tas li thiab kev saib xyuas kom tiv thaiv kev xeb, granite tsuas yog xav tau ib qho yooj yim so-down nrog cov tshuaj ntxuav tshwj xeeb. Ntxiv mus, granite tsis yog magnetic. Rau CMMs siv rau hauv cov khoom siv hluav taws xob lossis cov chaw muaj zog magnetic, qhov no yog qhov tseem ceeb ntawm kev nyab xeeb thiab qhov tseeb.
Ib qho ntawm cov yam ntxwv tshwj xeeb tshaj plaws ntawm granite yog nws qhov "tsis yog burring". Yog tias lub phaj granite lossis lub hauv paus tshuab raug ntaus lossis tawg, cov khoom siv tsis "nceb" lossis thawb lub pob zeb ncig qhov chaw cuam tshuam. Qhov no txhais tau tias qhov tiaj tiaj ntawm qhov chaw tseem zoo li qub, tiv thaiv cov kabmob cua thiab qhov tseeb ntawm tus choj txav mus los.
Lub Mechanical Legacy ntawm Cast Iron
Txawm hais tias granite tswj hwm kev lag luam CMM, cov hlau cam khwb cia tseem yog cov khoom siv tseem ceeb hauv lub ntiaj teb dav dav ntawm kev tsim kho precision thiab kev tsim khoom hnyav. Cov hlau cam khwb cia grey zoo lossis hlau ductile yog tus qauv kub rau cov txaj siv tshuab thiab cov platform kev lag luam loj. Qhov laj thawj yog nyob rau hauv nws cov qauv rigidity thiab nws lub peev xwm los pov rau hauv cov duab nyuaj.
Cov platforms hlau cam khwb cia muaj qib "kev tawv nqaij" uas granite tsis tuaj yeem sib piv. Hauv cov ntawv thov uas muaj cov khoom siv hnyav lossis cov khoom thauj hnyav, hlau cam khwb cia yuav tsis tawg thaum muaj kev ntxhov siab heev. Qhov no yog vim li cas cov platforms hlau cam khwb cia feem ntau siv ua qhov chaw sib dhos thiab kuaj thawj zaug hauv kev tsim khoom tsheb thiab aerospace. Lub platform hlau cam khwb cia zoo, ua kom zoo thiab raug khawb, muab qhov chaw siv uas tuaj yeem ua tau raws li qhov nyuaj ntawm lub neej kev lag luam hnyav thaum tswj hwm qhov tiaj tiaj zoo kawg nkaus.
Tsis tas li ntawd xwb, cov hlau cam khwb cia muaj cov modulus siab ntawm elasticity, ua rau nws zoo heev rau cov khoom uas yuav tsum tiv taus kev khoov thaum muaj qhov hnyav. Rau cov haujlwm tshuaj xyuas loj uas qhov workpiece hnyav ntau tons, lub platform hlau cam khwb cia uas muaj zog feem ntau muab cov qauv txhawb nqa tsim nyog uas lub kaw lus ua los ntawm pob zeb xwb yuav nyuaj rau haum yam tsis muaj qhov loj heev.
Kev co thiab kev co: Kev sib ntaus sib tua ntsiag to
Hauv txhua daim ntawv thov ntsuas, kev co yog tus yeeb ncuab. Nws ua rau muaj suab nrov rau hauv cov ntaub ntawv thiab tuaj yeem ua rau muaj kev ua yuam kev hauv cov khoom siv kov rhiab heev. Granite ua tau zoo heev ntawm kev txo cov kev co siab vim nws cov qauv sab hauv uas ntom, muaj qhov, thiab tsis sib xws. Nws "nqus" lub zog ntawm lub khw muag khoom, tsim kom muaj ib puag ncig ntsiag to rau tus choj ntsuas kom ua haujlwm.
Cov hlau cam khwb kuj muaj cov yam ntxwv zoo ntawm kev co zoo - zoo dua li hlau - tab sis nws feem ntau teb rau qhov sib txawv ntawm qhov resonance qis. Hauv ntau qhov chaw tsim khoom siab, qhov kev daws teeb meem zoo tshaj plaws tsis yog xaiv ib qho dhau ib qho, tab sis nkag siab qhov twg txhua qhov haum. Rau qhov kev txav mus los ntawm ultra-precision, sub-micron ntawm CMM choj, kev co ntawm granite feem ntau yog qhov nyiam dua. Rau qhov hnyav, vibrating ib puag ncig ntawm lub chaw machining lossis kab sib dhos, qhov loj thiab sab hauv damping ntawm lub platform hlau cam khwb feem ntau yog qhov kev xaiv zoo dua.
Kev Txij Nkawm, Kev Siv Tau Ntev, thiab Kev Siv Nyiaj Tau Zoo
Los ntawm kev saib xyuas, granite yog tus yeej meej rau CMM daim ntawv thov. Nws txoj kev tiv thaiv kev hnav thiab cov yam ntxwv ib puag ncig txhais tau tias lub hauv paus granite tuaj yeem tswj nws qhov tiaj tiaj rau ntau xyoo nrog kev cuam tshuam tsawg kawg nkaus. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov platforms hlau cam khwb cia muaj qhov zoo tshwj xeeb: lawv tuaj yeem "rov kho dua" los ntawm kev khawb tes lossis sib tsoo yooj yim dua hauv qee qhov kev lag luam loj.
Thaum soj ntsuam tus nqi, ib tug yuav tsum saib ntawm "Tag Nrho Tus Nqi ntawm Kev Muaj." Lub hauv paus granite tej zaum yuav muaj tus nqi khoom siv pib siab dua lossis qhov hnyav thauj khoom, tab sis qhov tsis muaj cov kev cai tiv thaiv xeb thiab nws txoj kev tiv thaiv kev puas tsuaj rau ib puag ncig feem ntau ua rau nws pheej yig dua li 20 xyoo. Ntawm qhov tod tes, rau cov cheeb tsam tshuaj xyuas hauv pem teb loj lossis cov haujlwm teeb tsa tes, cov platforms hlau cam khwb cia muab qhov ruaj khov uas muab tus nqi zoo dua hauv cov chaw muaj neeg coob coob uas pob zeb yuav raug puas tsuaj los ntawm cov hlau hnyav.
Xaus Lus: Xaiv Qhov Zoo Rau Koj Lub Chaw
Qhov kev xaiv ntawm cov granite precision thiab cov hlau cam khwb cia thaum kawg nyob ntawm koj daim ntawv thov tshwj xeeb. Yog tias koj lub hom phiaj yog kev ceev ceev, kev tshuaj xyuas tsis siv neeg nrog qhov tseeb sub-micron hauv chav kuaj mob tswj hwm, qhov ruaj khov thiab damping ntawm lub hauv paus granite dub yog qhov tsis muaj qhov sib tw. Nws yog cov khoom siv ntawm yav tom ntej rau kev ntsuas qhov tseeb.
Txawm li cas los xij, lub ntiaj teb kev lag luam tseem vam khom lub zog thiab kev hloov pauv ntawm cov hlau cam khwb cia rau kev sib dhos, kev teeb tsa hnyav, thiab cov haujlwm engineering loj. Ob qho tib si yog cov ncej tseem ceeb ntawm kev tsim khoom niaj hnub. Los ntawm kev nkag siab txog qhov zoo ntawm cov granite thiab cov qauv ntawm cov hlau cam khwb cia, cov engineers tuaj yeem tsim cov txheej txheem tshuaj xyuas thiab tsim khoom uas tsis yog tsuas yog raug niaj hnub no tab sis yuav nyob ruaj khov rau ntau tiam neeg tom ntej. Txawm hais tias koj tab tom txhim kho CMM tshiab lossis txhim kho koj lub hauv pem teb sib dhos, kev xaiv cov khoom siv hauv paus yog qhov tseem ceeb tshaj plaws hauv kev ua kom muaj kev ncaj ncees ntawm koj txoj haujlwm engineering.
