Nyob rau hauv lub ntiaj teb no ntawm metrology thiab precision sib dhos, lub hom phiaj tseem ceeb yog, txoj cai, ntawm lub flatness ntawm granite platform ua hauj lwm nto. Txawm li cas los xij, kev tsim cov phaj siab zoo, ruaj khov, thiab muaj kev nyab xeeb yuav tsum tau saib xyuas cov npoo-tshwj xeeb, kev coj ua ntawm chamfering lossis rounding lawv.
Txawm hais tias tsis ncaj qha cuam tshuam rau sub-micron raug ntawm lub dav hlau ua haujlwm, lub chamfered ntug yog ib qho tseem ceeb uas yuav tsum tau ua kom lub phaj lub neej ntev, tiv thaiv cov khoom siv ntsuas, thiab ua kom muaj kev nyab xeeb ntawm cov kws tshaj lij. Nws yog ib qho tseem ceeb ntawm cov niaj hnub, kev lag luam granite.
Qhov Yuav Tsum Tau Ua Ntawm Ntug
Vim li cas cov tuam ntxhab txhob txwm tshaj tawm cov ntse, 90∘ kaum qhov chaw ua haujlwm raws li sab ntsej muag ntawm granite slab? Nws boils mus rau peb lub ntsiab yog vim li cas: durability, kev nyab xeeb, thiab functionality.
1. Tiv thaiv chipping thiab puas
Granite yog ib qho nyuaj heev, tab sis qhov hardness no kuj ua rau lub ntse ntse, tsis muaj kev txhawb nqa ntug brittle thiab raug rau chipping. Nyob rau hauv ib tug tibneeg hu tauj coob manufacturing los yog calibration lab, txav yog tas li. Yog tias qhov ntsuas hnyav, lub teeb tsa, lossis lub cuab yeej ua rau lub ntsej muag ntse, tsis kho lub ces kaum, qhov cuam tshuam tuaj yeem ua rau lub nti tawg tau yooj yim.
- Tiv thaiv kev nqis peev: Ib qho chamfered (los yog rounded / radiused) ntug tsim ib qho chaw ruaj khov, qhov chaw tsis zoo. Qhov "tawg ntug" no ua rau muaj txiaj ntsig zoo cuam tshuam qhov cuam tshuam ntawm thaj chaw loj dua, txo qis kev ntxhov siab thiab kev pheej hmoo ntawm kev tawg. Kev tiv thaiv ntug txhais tau tias tiv thaiv cov qauv kev ntseeg siab thiab tus nqi zoo nkauj ntawm tag nrho cov phaj.
- Tiv thaiv Burrs: Tsis zoo li cov hlau, granite tsis tsim burrs, tab sis ib nti los yog nick tuaj yeem tsim qhov tsis sib xws uas tuaj yeem rub cov ntaub tu los yog ua rau muaj kev phom sij. Cov ntug sib npaug minimizes cov kab txhaum cai no.
2. Txhim khu kev nyab xeeb ntawm tus neeg ua haujlwm
Qhov hnyav hnyav thiab ntse, ntuj ntug ntawm cov granite loj heev ua rau muaj kev phom sij loj. Kev tuav, thauj, thiab txawm tias ua haujlwm ib sab ntawm lub phaj uas tsis muaj chamfered yog qhov txaus ntshai.
- Kev Tiv Thaiv Kev Raug Mob: Lub ntsej muag ntse, ua tiav tiav granite tuaj yeem yooj yim txiav lossis khawb tus kws tshaj lij. Ntug tawg yog thawj zaug thiab qhov tseem ceeb tshaj plaws kev ntsuas kev nyab xeeb, tshem tawm qhov muaj peev xwm rau kev raug mob thaum teeb tsa, ntsuas ntsuas, thiab siv txhua hnub.
3. Txhim kho kev ua haujlwm ntev
Chamfering pab hauv kev siv dav dav thiab kev saib xyuas ntawm lub phaj. Nws ua kom yooj yim rau kev txav ntawm cov npog thiab cov khoom siv ntxiv thiab ua kom yooj yim rau daim ntawv thov kev tiv thaiv txheej los yog daim kab xev. Ib tug huv, tiav ntug yog ib lub cim ntawm ib tug kws-qib metrology ntsuas.
Xaiv txoj cai Specification: R-Radius vs. Chamfer
Thaum qhia txog kev kho ntug, cov chaw tsim khoom feem ntau siv lub vojvoog tsim, xws li R2 lossis R3 (qhov twg 'R' sawv cev rau Radius, thiab tus lej yog qhov ntsuas hauv millimeters). Lub chamfer, los yog "bevel," yog technically ib lub tiaj tus, lub kaum sab xis txiav, tab sis cov ntsiab lus feem ntau siv sib hloov mus rau kev xa mus rau txhua qhov tawg. Nyob rau hauv precision granite, ib puag ncig lub vojvoog yog feem ntau nyiam rau superior nti kuj.
Nkag siab R2 thiab R3
Qhov kev xaiv ntawm kev qhia tshwj xeeb, xws li R2 lossis R3 lub vojvoog, feem ntau yog qhov teeb meem ntawm nplai, zoo nkauj, thiab tuav.
- R2 (Radius 2 mm): Qhov no yog ib qho yooj yim, hloov maj mam, thiab ua haujlwm lub vojvoog, feem ntau siv rau cov ntawv me me, qhov tseeb heev. Nws muab kev nyab xeeb txaus thiab kev tiv thaiv chip yam tsis muaj qhov pom kev zoo.
- R3 (Radius 3 mm): Ib lub vojvoog loj me me, R3 muaj kev tiv thaiv kev tiv thaiv hnyav dua. Nws tau nquag teev tseg rau cov rooj saum npoo loj, xws li cov siv hauv qab Coordinate Measuring Machines (CMMs) lossis lwm yam khoom siv hnyav, qhov kev pheej hmoo ntawm kev raug mob tshwm sim ntau dua.
Lub vojvoog tsis ua raws li tus qauv kev lag luam nruj (xws li ASME flatness qib) tab sis raug xaiv los ntawm cov chaw tsim khoom los ua kom sib npaug rau lub phaj qhov loj thiab qhov chaw ua haujlwm. Rau qhov loj-loj precision granite, ua kom muaj kev sib raug zoo, zoo-polished R3 ntug yog ib qho kev nqis peev hauv kev ua haujlwm ntev thiab kev nyab xeeb hauv khw.
Thaum kawg, cov ntsiab lus me me ntawm R-radius ntug yog qhov taw qhia muaj zog ntawm cov chaw tsim khoom cog lus rau kev ua tau zoo uas txuas ntxiv mus rau qhov chaw ua haujlwm tiaj tus, kom ntseeg tau tias tag nrho lub platform yog ruaj khov, nyab xeeb, thiab ua kom ntev.
