Hauv ntiaj teb ntawm kev ntsuas thiab kev sib dhos ua kom raug, qhov tseem ceeb tshaj plaws yog, yog lawm, ntawm qhov tiaj tiaj ntawm lub platform granite qhov chaw ua haujlwm. Txawm li cas los xij, kev tsim cov phaj nto zoo tiag tiag, ruaj khov, thiab muaj kev nyab xeeb yuav tsum tau ua tib zoo saib xyuas cov npoo - tshwj xeeb, kev xyaum ua kom chamfering lossis puag ncig lawv.
Txawm hais tias tsis cuam tshuam ncaj qha rau qhov tseeb ntawm lub dav hlau ua haujlwm hauv qab micron, ntug chamfered yog ib qho tseem ceeb uas ua rau lub phaj ntev dua, tiv thaiv cov khoom siv ntsuas muaj nqis, thiab ua kom muaj kev nyab xeeb ntawm tus kws tshaj lij. Nws yog ib qho tseem ceeb ntawm kev tsim khoom granite niaj hnub no.
Qhov Yuav Tsum Tau Ua Kom Tawg Ntug
Vim li cas cov chaw tsim khoom thiaj li txhob txwm tshem tawm lub ces kaum ntse ntse, 90∘ qhov chaw ua haujlwm ntsib sab ntawm lub pob zeb granite? Nws yog vim peb qho laj thawj tseem ceeb: kev ruaj khov, kev nyab xeeb, thiab kev siv tau zoo.
1. Tiv thaiv kev tawg thiab kev puas tsuaj
Granite yog ib yam khoom tawv heev, tiam sis qhov tawv no kuj ua rau cov ntug ntse, tsis muaj kev txhawb nqa, thiab yooj yim tawg. Hauv chav tsim khoom lossis chav ntsuas uas muaj neeg coob heev, kev txav mus los yeej tsis tu ncua. Yog tias lub ntsuas hnyav, lub teeb, lossis cov cuab yeej tsoo rau ntawm lub ces kaum ntse, tsis tau kho, qhov kev cuam tshuam tuaj yeem ua rau cov chip tawg yooj yim.
- Kev Tiv Thaiv Kev Nqis Peev: Ib lub ntug uas muaj chamfered (lossis puag ncig/radiused) tsim ib thaj chaw ruaj khov thiab nkhaus. Qhov "ntug tawg" no ua rau muaj kev cuam tshuam tsis tau xav txog ntau dua li thaj chaw loj dua, txo qhov kev ntxhov siab thiab kev pheej hmoo ntawm kev tawg. Kev tiv thaiv ntug txhais tau tias tiv thaiv kev ncaj ncees ntawm cov qauv thiab tus nqi zoo nkauj ntawm tag nrho lub phaj.
- Tiv Thaiv Kab Ntsig: Tsis zoo li hlau, granite tsis tsim kab nrib pleb, tab sis ib qho tawg lossis qhov khawb tuaj yeem ua rau muaj qhov chaw tsis sib luag uas tuaj yeem ntes cov ntaub ntxuav lossis ua rau muaj kev phom sij. Cov npoo puag ncig txo cov kab tsis zoo no.
2. Txhim Kho Kev Nyab Xeeb ntawm Tus Neeg Ua Haujlwm
Qhov hnyav thiab cov npoo ntse ntawm cov pob zeb granite loj heev ua rau muaj kev phom sij loj heev. Kev tuav, kev thauj mus los, thiab txawm tias ua haujlwm ze ntawm lub phaj tsis muaj chamfered kuj muaj kev pheej hmoo.
- Kev Tiv Thaiv Kev Raug Mob: Cov ntug granite uas ntse thiab zoo nkauj tuaj yeem txiav lossis khawb tau yooj yim rau tus kws kho. Kev tawg ntug yog qhov tseem ceeb tshaj plaws los ntsuas kev nyab xeeb, tshem tawm qhov ua rau raug mob thaum teeb tsa, kho, thiab siv txhua hnub.
3. Txhim Kho Kev Ua Haujlwm Ntev
Kev txiav cov npoo pab txhawb kev siv dav dav thiab kev saib xyuas lub phaj. Nws ua rau kev txav mus los ntawm cov npog thiab cov khoom siv yooj yim dua thiab ua kom yooj yim rau kev siv cov tshuaj tiv thaiv lossis daim kab xev ntug. Ib ntug huv si thiab tiav yog lub cim ntawm cov cuab yeej ntsuas kev ua haujlwm.
Xaiv Cov Lus Qhia Tshwj Xeeb: R-Radius vs. Chamfer
Thaum teev cov kev kho ntug, cov chaw tsim khoom feem ntau siv lub cim qhia txog lub vojvoog, xws li R2 lossis R3 (qhov twg 'R' sawv cev rau Radius, thiab tus lej yog qhov ntsuas hauv millimeters). Lub chamfer, lossis "bevel," yog kev txiav tiaj tus, lub kaum sab xis, tab sis cov lus no feem ntau siv hloov pauv los xa mus rau txhua qhov ntug tawg. Hauv cov granite precision, lub vojvoog puag ncig feem ntau yog qhov zoo dua rau kev tiv thaiv chip zoo dua.
Nkag Siab Txog R2 thiab R3
Qhov kev xaiv ntawm cov lus qhia tshwj xeeb, xws li lub vojvoog R2 lossis R3, feem ntau yog qhov teeb meem ntawm qhov ntsuas, kev zoo nkauj, thiab kev tuav.
- R2 (Radius 2 hli): Qhov no yog ib qho radius uas siv ntau, tsis pom tseeb, thiab ua haujlwm tau zoo, feem ntau siv rau ntawm cov phaj tshuaj xyuas me me, meej heev. Nws muab kev nyab xeeb txaus thiab kev tiv thaiv chip yam tsis pom kev zoo.
- R3 (Radius 3 hli): Lub vojvoog loj dua me ntsis, R3 muab kev tiv thaiv zoo dua tiv thaiv kev cuam tshuam hnyav dua. Nws feem ntau tau teev tseg rau cov rooj saum npoo loj dua, xws li cov uas siv hauv qab Coordinate Measuring Machines (CMMs) lossis lwm yam khoom siv hnyav, qhov twg muaj kev pheej hmoo ntawm kev cuam tshuam sab nraud ntau dua.
Lub vojvoog tsis ua raws li tus qauv kev lag luam nruj (zoo li ASME flatness qib) tab sis yog xaiv los ntawm tus neeg tsim khoom kom sib npaug rau lub phaj qhov loj tag nrho thiab qhov chaw ua haujlwm npaj tseg. Rau cov granite loj precision, kev ua kom muaj R3 ntug sib xws, zoo-polished yog kev nqis peev rau kev ruaj khov mus sij hawm ntev thiab kev nyab xeeb hauv pem teb.
Thaum kawg, qhov me me ntawm ntug R-radius yog qhov qhia tau zoo ntawm kev cog lus ntawm cov chaw tsim khoom rau qhov zoo uas nthuav dav dhau ntawm qhov chaw ua haujlwm tiaj tus, kom ntseeg tau tias tag nrho lub platform ruaj khov, muaj kev nyab xeeb, thiab ua kom kav ntev.
