Kev tsim cov qauv ua haujlwm ua haujlwm yog ib theem tseem ceeb hauv kev tsim cov khoom lag luam. Rau cov khoom siv uas xav tau lub zog siab - rau - qhov hnyav piv, thermal conductivity zoo, thiab kev ua haujlwm zoo, aluminium yog qhov kev xaiv zoo tshaj plaws. Cov lus qhia no muab cov ntsiab lus dav dav ntawm cov ntsiab lus tseem ceeb rau kev ua tiav cov qauv txhuas ntawm CNC machining, cov txheej txheem tsim tawm.
Kev xaiv cov khoom siv rau Aluminium Prototypes
Xaiv qhov tsim nyog aluminium alloy yog thawj zaug thiab tseem ceeb tshaj plaws. Ntau qib feem ntau ua haujlwm hauv CNC machining, txhua tus muaj cov khoom sib txawv.
- 6061:Qhov no yog qhov siv ntau tshaj plaws aluminium alloy rau prototyping thiab dav -cov ntaub ntawv siv. Nws muaj kev sib xyaw ua ke zoo ntawm lub zog, weldability, thiab corrosion kuj. Nws cov machinability zoo heev ua rau nws muaj ntau yam thiab raug nqi - kev xaiv zoo rau ntau yam qauv qauv.
- 7075:Paub txog nws lub zog siab heev, piv rau ntau cov hlau, 7075 yog qhov zoo tagnrho rau siab - cov khoom siv kev ntxhov siab, xws li cov hauv aerospace lossis siab - kev ua haujlwm hauv tsheb. Txawm li cas los xij, nws muaj kev tiv thaiv corrosion tsawg dua 6061 thiab tsis tshua muaj vuam.
- 2024:Cov hlau no muab lub zog siab thiab ua kom qaug zog zoo tab sis nthuav tawm tsis zoo corrosion kuj tshwj tsis yog nws yog clad lossis anodized. Nws yog feem ntau siv hauv cov qauv hauv aerospace.
- 5052:Distinguished los ntawm nws superior corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv marine ib puag ncig, 5052 muaj zog qaug zog ntau dua 6061 tab sis tsis yog cua sov- kho. Nws yog feem ntau siv rau cov ntawv hlau qhov chaw.
Qhov kev xaiv yuav tsum yog ua raws li kev soj ntsuam kom zoo ntawm cov qauv kev ua haujlwm, suav nrog cov khoom siv tshuab, kev cuam tshuam ib puag ncig, thiab tom qab- cov kev xav tau ua tiav.
CNC Machining txheej txheem
CNC machining encompasses ob peb leej, computer - tswj kev rho tawm txoj kev. Ob txheej txheem tseem ceeb rau txhuas yog milling thiab tig, feem ntau siv ua ke ntawm ntau -axis tshuab.
- CNC Milling:Cov txheej txheem no suav nrog rotating ntau- taw tes txiav cov cuab yeej kom tshem tawm cov khoom ntawm ib qho chaw ua haujlwm. Nws yog qhov zoo tagnrho rau kev tsim cov geometries nyuaj, hnab tshos, qhov, thiab qhov chaw contoured . 3-axis milling yog tus qauv, thaum 4 thiab 5-axis machining tso cai rau kev tsim cov khoom nyuaj hauv ib qho kev teeb tsa, txo lub sijhawm thiab muaj peev xwm ua yuam kev.
- CNC tig:Cov txheej txheem no tig lub workpiece thaum ib zaug -taw tes txiav cov cuab yeej tshem tawm cov khoom. Nws yog feem ntau siv rau kev tsim khoom cylindrical lossis conical qhov chaw. Kev ua haujlwm zoo li tig ntsej muag, tho txawv, thiab threading yog ua tau zoo ntawm lub tshuab dhos.
Cov khw muag khoom niaj hnub no feem ntau ntiav CNC tig cov chaw nrog kev sib xyaw ua ke (mills-tig chaw) los tsim cov khoom sib txawv ua tiav hauv ib qho kev ua haujlwm.
Tsim rau Manufacturability (DFM) Cov Cai
Ua raws li DFM cov hauv paus ntsiab lus yog qhov tseem ceeb rau kev txhim kho kev tsim khoom, nqi, thiab lub sijhawm ua haujlwm ntawm koj cov qauv txhuas.
- Internal Radii:Txhua lub kaum sab hauv ntsug yuav tsum muaj lub vojvoog. Lub vojvoog pom zoo yuav tsum yog me ntsis loj dua li lub vojvoog lub cuab yeej npaj kom tso cai rau txoj hauv kev huv si thiab zam cov cuab yeej tawg.
- Phab ntsa Thickness:Tsis txhob muaj cov phab ntsa nyias nyias los tiv thaiv qhov tsis sib xws, sib tham thaum lub tshuab ua haujlwm, thiab qhov ua tsis tiav. Qhov tsawg kawg nkaus phab ntsa thickness ntawm 0.8 hli feem ntau pom zoo, tab sis 1.0 hli los yog ntau tshaj muab cov npoo zoo dua ntawm kev nyab xeeb.
- Qhov Loj:Tus qauv laum me me yuav tsum tau siv txhua qhov chaw kom txo tau tus nqi thiab lub sijhawm ua haujlwm. Rau threaded qhov, xyuas kom txaus cov khoom nyob ib ncig ntawm lub qhov kom muaj kev ncaj ncees xov.
- Deep Cavities thiab Pockets:Machining cov yam ntxwv sib sib zog nqus heev yuav tsum tau siv cov cuab yeej ntev, uas tuaj yeem cuam tshuam, ua rau qhov tsis raug thiab tsis zoo ntawm qhov kawg. Kev txwv qhov tob ntawm kab noj hniav mus rau plaub npaug ntawm lawv txoj kab uas hla yog ib qho kev xyaum zoo.
- Tolerances:Qhia qhov kam rau ua raws li kev xav tau ntawm kev ua haujlwm. Tsis tsim nyog nruj tolerances ho nce machining lub sij hawm thiab nqi. Standard machining tolerances ntawm ± 0.1 hli feem ntau yog txaus rau ntau yam uas tsis yog - tseem ceeb nta.
Ntsiab lus tshaj tawm -Kev xaiv ua tiav
Tom qab machining, ntau yam kev tshaj tawm - cov haujlwm ua haujlwm tuaj yeem siv los txhim kho tus qauv ntawm cov khoom thiab cov tsos.
- Deburring:Cov kauj ruam tseem ceeb no tshem tawm cov npoo ntse thiab burrs sab laug los ntawm cov txheej txheem machining, txhim kho kev nyab xeeb thiab kev tuav ib feem.
- Bead Blasting:Cov txheej txheem no tsim ib qho matte los yog satin nto tiav, uas kuj yog ib qho zoo heev rau kev npaj qhov chaw rau anodizing.
- Anodizing:Electrochemical txheej txheem uas ua rau kom corrosion kuj thiab nto hardness. Anodizing kuj tuaj yeem siv los ntxiv xim (Hom II) lossis tsim ib qho nyuaj heev, hnav- tiv taus nto (Hom III, hardcoat).
- Chemical Film (Chromate Conversion Txheej):Siv raws li cov txheej txheej nyias nyias, nws muab kev tiv thaiv corrosion zoo thiab ua haujlwm zoo tshaj plaws rau cov xim.
Hauv kev xaus, lub tswv yim ua tiav rau aCNC aluminium qauvhinges ntawm txoj kev sib koom ua ke: xaiv cov hlau zoo, tsim rau cov txheej txheem machining, thiab siv cov txheej txheem tiav. Los ntawm kev nkag siab thiab siv cov hauv paus ntsiab lus no, engineers thiab procurement specialists tuaj yeem ua haujlwm zoo ntawm CNC machining los tsim cov khoom siv siab tshaj -zoo, ua haujlwm zoo aluminium prototypes uas raug tsim kom muaj lub siab xav thiab nrawm lub sijhawm- mus rau - lag luam.
