Chamfering yog hais txog kev txiav cov ces kaum ntawm lub workpiece rau hauv ib qho kev nqes hav. Chamfering yog tshem tawm cov burrs ntawm qhov chaw vim machining, thiab kom yooj yim rau kev sib dhos ntawm cov khoom, chamfering feem ntau yog ua thaum kawg ntawm cov khoom. Lub kaum sab xis feem ntau yog 45 degrees, 30 degrees lossis 60 degrees.
Lub hom phiaj yog kom tshem tawm cov burrs ntawm qhov chaw vim machining.
Feem ntau, txoj haujlwm ntawm chamfering yog tshem tawm burrs thiab ua kom lawv zoo nkauj. Txawm li cas los xij, cov chamfers tshwj xeeb tau taw qhia hauv cov duab kos yog feem ntau cov kev xav tau ntawm cov txheej txheem kev teeb tsa, xws li cov lus qhia kev teeb tsa ntawm cov kabmob, thiab qee qhov arc chamfers (los yog hu ua arc hloov pauv) tuaj yeem txo qhov kev ntxhov siab thiab ntxiv dag zog rau cov ncej. Cov nyhuv ntawm lub zog ntawm chav kawm ib feem. Tsis tas li ntawd, nws kuj txhawb kev sib dhos, feem ntau ua ntej machining tiav. Ntawm cov khoom siv ua liaj ua teb, tshwj xeeb tshaj yog lub ntsej muag kawg ntawm cov fittings thiab puag ncig lub qhov feem ntau ua tiav rau hauv chamfer ntawm li 45 degree. Cov chamfers no muaj ntau txoj haujlwm, thiab yuav tsum tau ua tib zoo xyuas thiab siv tag nrho thaum lub sijhawm ua haujlwm tu, txwv tsis pub nws yuav ua rau muaj ntau yam teeb meem rau kev saib xyuas ntawm cov tshuab ua liaj ua teb, thiab txawm tias yuav ua rau tsis muaj kev cia siab. Piv txwv li, chamfering kuj tau ua ua ntej kev tsim cov txheej txheem me me xws li bolts, kom cov khoom siv tau yooj yim nkag mus rau hauv txoj kev tuag.
Lub ntsiab lus muaj cov ntsiab lus hauv qab no:
1. Cov kabmob steel yuav tsum muaj cov chamfers thaum lub sijhawm ua haujlwm ntxhib ua ntej kev kho cua sov, uas ua lub luag haujlwm tseem ceeb hauv kev tso tawm kev ntxhov siab, rov ua dua tshiab ntawm cov qauv sab hauv, tsis tshua muaj cov kab nrib pleb thiab txo qhov deformation thaum kho cov khoom siv hluav taws xob. Chamfering tuaj yeem daws qhov teeb meem ntawm kev ntxhov siab concentration.
2. Chamfering thiab deburring, kom cov khoom tsis ntse thiab yuav tsis txiav cov neeg siv.
3. Nws ua lub luag haujlwm ntawm kev taw qhia thiab qhov chaw thaum lub rooj sib txoos.
