Thaum xaiv ib qho kawg zeb rau ib txoj haujlwm machining, muaj ntau yam tseem ceeb uas yuav tsum tau xav txog kom ntseeg tau tias kev ua tau zoo thiab kev ua haujlwm ntev ntawm lub cuab yeej. Txoj kev xaiv yog nyob ntawm ntau yam ntawm cov khoom siv machined, cov khoom xav tau, thiab lub peev xwm ntawm lub tshuab milling.
1.Machining cov khoom:Kev xaiv ntawm cov khoom siv kawg zeb feem ntau yog nyob ntawm cov khoom siv machined. Piv txwv li, high-speed steel (HSS) kawg mills yog feem ntau siv rau machining softer cov ntaub ntawv xws li txhuas, thaum carbide kawg mills yog zoo haum rau cov ntaub ntawv nyuaj xws li stainless hlau vim lawv hardness ntau dua thiab kub tsis kam. Cov txheej txheej zoo li Titanium Nitride (TiN) lossis Titanium Aluminium Nitride (TiAlN) tuaj yeem txhim kho lub cuab yeej lub neej los ntawm kev txo cov kev sib txhuam thiab ua rau hnav tsis kam.
2. Txoj kab uas hla thiab qhov ntev ntawm kev txiav:Txoj kab uas hla thiab qhov ntev ntawm qhov kawg zeb cuam tshuam rau ob qho tag nrho ntawm kev txiav thiab cov cuab yeej muaj peev xwm tshem tawm cov khoom. Cov diameters loj dua muab cov cuab yeej ruaj khov tab sis yuav tsis haum rau cov ntsiab lus zoo sib xws. Qhov ntev ntawm kev txiav yuav tsum ua kom haum rau qhov tob ntawm cov khoom siv machined, nrog ntev ntev siv rau kev txiav tob. Txawm li cas los xij, ntev kawg mills tuaj yeem ua rau muaj kev vibration thiab deflection, cuam tshuam qhov ua tiav zoo.
3.Number of Flutes:Lub flutes ntawm qhov kawg zeb yog cov npoo uas tshem tawm cov khoom. Tus naj npawb ntawm flutes cuam tshuam qhov ua tiav zoo, nti khiav tawm, thiab pub tus nqi. Tsawg flutes tso cai rau cov nti loj dua, uas muaj txiaj ntsig zoo rau cov ntaub ntawv zoo li txhuas. Nyob rau hauv sib piv, ntau flutes tsim ib tug finer tiav thiab feem ntau yog siv rau cov ntaub ntawv nyuaj. Txawm li cas los xij, ntau lub flutes tuaj yeem txo qhov chaw nti, ua rau muaj cua sov tsim thiab hnav cov cuab yeej ntxov ntxov.
4. Hom Txiav:End mills yog tsim los rau tej hom kev txiav. Roughing kawg mills, piv txwv li, muaj serrated npoo uas tshem tawm ntau cov khoom sai sai tab sis nrog ib tug rougher tiav. Finishing kawg mills, ntawm qhov tod tes, muaj cov npoo smoother thiab siv los ua kom tiav qhov zoo nkauj. Kev xaiv ntawm roughing thiab xov cov cuab yeej nyob ntawm lub machining theem thiab qhov xav tau qhov zoo.
5.Machine thiab Spindle Peev Xwm:Lub tshuab milling lub peev xwm, tshwj xeeb tshaj yog nws cov ntxaiv, ua lub luag haujlwm tseem ceeb hauv kev xaiv qhov kawg zeb. Cov yam ntxwv xws li spindle ceev, horsepower, thiab torque txwv qhov loj thiab hom kawg zeb uas yuav siv tau zoo. Lub spindle high-ceev muaj peev xwm ua tau me me, sib zog kawg mills, whereas qhov qis-ceev, siab-torque spindle yog zoo dua rau loj kawg mills.
6. Txiav ceev thiab pub tus nqi:Kev txiav ceev thiab pub tus nqi yog qhov tseem ceeb hauv kev xaiv qhov kawg zeb vim lawv txiav txim siab lub cuab yeej muaj peev xwm tshem tawm cov khoom siv tau zoo yam tsis muaj kev puas tsuaj. Cov nqi no txawv raws li cov khoom uas raug machined thiab hom kev txiav. Piv txwv li, cov ntaub ntawv softer tuaj yeem siv rau ntawm qhov nrawm dua nrog cov nqi pub ntau dua, thaum cov ntaub ntawv nyuaj yuav tsum tau qeeb qeeb thiab ceev faj ntxiv.
7.Coolant thiab Lubrication:Kev siv cov dej txias lossis cov roj nplua nyeem tuaj yeem cuam tshuam rau kev ua haujlwm ntawm qhov kawg zeb. Coolants pab dissipate tshav kub thiab txo cov cuab yeej hnav, tshwj xeeb tshaj yog nyob rau hauv ntev los yog tob txiav. Qee qhov kawg mills tau tsim nrog cov channel los txhim kho cov dej txias kom zoo rau qhov txiav ntug.
8.Tool Geometry:Lub geometry ntawm qhov kawg zeb, nrog rau lub kaum sab xis ntawm lub flutes thiab cov duab ntawm kev txiav ntug, kuj plays lub luag haujlwm tseem ceeb. Piv txwv li, qhov sib txawv helix kawg mills tuaj yeem txo qhov kev vibration, uas yog qhov muaj txiaj ntsig zoo thaum ua haujlwm ntev overhangs lossis nyias-walled qhov chaw.
9.Workpiece Fixturing thiab Rigidity:Yuav ua li cas lub workpiece ruaj ntseg thiab tag nrho rigidity ntawm lub teeb yuav cuam tshuam rau kev xaiv ntawm kawg zeb. Kev teeb tsa tsis tshua muaj zog yuav xav tau lub cuab yeej nrog lub taub loj dua los tiv thaiv deflection.
10. Kev txiav txim siab nyiaj txiag:Thaum kawg, cov khoom lag luam xws li tus nqi ntawm cov cuab yeej piv rau nws qhov kev cia siab lifespan, thiab tus nqi ntawm ib feem machined, kuj yuav tsum tau txiav txim siab. High-performance kawg mills tej zaum yuav muaj tus nqi pib dua tab sis tuaj yeem ua rau qis dua tag nrho cov nqi machining vim lub cuab yeej siv ntev dua thiab kev ua haujlwm nrawm dua.
Hauv kev xaus, kev xaiv ntawm qhov kawg zeb yuav tsum muaj kev nkag siab zoo ntawm cov khoom siv los ua machined, machining ib puag ncig, thiab cov txiaj ntsig xav tau. Los ntawm kev ua tib zoo xav txog cov xwm txheej no, cov kws kho tshuab tuaj yeem xaiv qhov zoo tshaj plaws kawg zeb, uas ua rau kev tshem tawm cov khoom siv tau zoo, qhov zoo tshaj plaws nto tiav, thiab lub neej ntev ntawm cov cuab yeej.
