Kev tsim cov qib siab - zoo aluminium enclosures ntawm CNC machining yog lub hauv paus ntawm kev tsim khoom niaj hnub rau electronics, aerospace, thiab cov cuab yeej siv. Cov txheej txheem no sib txuas cov khoom siv science, precision engineering, thiab kev kho saum npoo rau cov khoom uas ua tau raws li kev ua haujlwm nruj thiab zoo nkauj. Tsab ntawv xov xwm no muab cov lus qhia txog kev ua haujlwm ntawm tus qauv kev ua haujlwm rau kev tsim cov khoom siv aluminium tiav, los ntawm cov khoom siv raw mus rau kev tshuaj xyuas zaum kawg.
1. Kev xaiv cov khoom siv thiab kev teeb tsa thawj zaug
Cov txheej txheem feem ntau pib nrog 6061 lossis 7075 aluminium alloy . 6061 yog dav nyiam rau nws cov machinability zoo, lub zog zoo - rau - qhov hnyav piv, thiab corrosion kuj. Cov khoom siv raw, feem ntau nyob rau hauv daim ntawv ntawm lub phaj los yog billet, yog ruaj khov kho rau lub txaj ntawm CNC milling tshuab. Cov qauv tsim kho yog qhov tseem ceeb, vim tias nws yuav tsum nruj me ntsis tuav lub workpiece thaum tso cai rau cov cuab yeej txiav kom siab tshaj plaws, txo qis qhov xav tau rov qab - kho. Cov ncauj lus kom ntxaws CAD (Computer-Aided Design) qauv tau muab txhais ua cov lus qhia machining (G-code) siv CAM (Computer-Aided Manufacturing) software, uas txhais cov cuab yeej txoj kev, spindle speeds, pub nqi, thiab txiav qhov tob.
2. Thawj CNC Machining Operations
Cov txheej txheem machining yog ua tiav hauv cov txheej txheem ua ntu zus kom ntseeg tau qhov tseeb qhov tseeb thiab qhov tseeb ntawm qhov chaw.
- Roughing: Cov theem pib no siv cov mills uas muaj zog kawg kom tshem tawm cov khoom loj sai sai, tawm hauv cov khoom me me (feem ntau yog 0.5-1.0 mm) rau kev ua tiav. High-efficiency roughing tswv yim yog siv los txo lub sij hawm voj voog.
- Kev Ua tiav: Kev ua tiav tiav yog ua tiav nrog cov cuab yeej zoo dua ntawm qhov nrawm dua thiab qis dua tus nqi noj kom ua tiav qhov kawg qhov ntev thiab nruj kam rau ua, feem ntau teev rau cov yam ntxwv tseem ceeb xws li mating nto thiab bore diameters. Kev kam rau siab tuaj yeem tuav hauv ± 0.05 hli lossis nruj dua rau cov yam ntxwv tshwj xeeb.
- Qhov Kev Ua: Kev sib xyaw ua ke ntawm drilling, reaming, thiab tapping ua haujlwm tsim los ntawm - qhov, threaded qhov (xws li, rau M3 los yog #4-40 screws), thiab counterbores. Cov txheej txheem yog tsim los xyuas kom meej qhov chaw raug thiab xov zoo.
- Contouring: Sab nraud profile ntawm lub thawv yog raug txiav los ntawm cov khoom loj dua. Rau txoj kev 3-axis lossis 5-axis machining, qhov no yuav suav nrog kev milling tag nrho cov duab geometry nyob rau hauv ib qho kev teeb tsa kom muaj qhov tseeb ntawm daim ntawv.
Thoob plaws hauv machining, ib qho kev ua kom txias tsis tu ncua yog siv los tswj qhov kub thiab txias, tshem tawm cov chips, thiab tiv thaiv aluminium adhesion rau cov cuab yeej txiav, yog li tiv thaiv ib feem thiab txuas lub neej ntawm cov cuab yeej.
3. Deburring thiab Initial Quality Control
Thaum machining tiav, ib feem yog ua tib zoo tshem tawm ntawm lub fixture. Tag nrho cov npoo ntse thiab burrs tsim thaum txiav yog meticulously tshem tawm los ntawm phau ntawv los yog automated deburring txheej txheem. Cov kauj ruam no yog qhov tseem ceeb rau ob tus neeg teb xov tooj kev nyab xeeb thiab xyuas kom haum thiab ua haujlwm zoo. Thawj zaug hauv -txheej txheem kev tswj xyuas zoo yog ua los ntawm cov cuab yeej siv tes xws li calipers thiab pin gauges los txheeb xyuas qhov loj me ntawm kev kos duab engineering.
4. Nto Finishing: Sandblasting thiab Anodizing
Kev kho deg txhim kho cov tsos, muab kev ntxhib los mos zoo ib yam, thiab txhim kho corrosion thiab hnav tsis kam.
- Sandblasting (Abrasive Blasting): Lub tshuab ntim khoom siv cov xuab zeb blasting nrog cov xov xwm zoo, xws li iav hlaws lossis txhuas oxide. Cov txheej txheem no tsim ib qho kev ntxhib los mos, matte deg zoo nkauj los ntawm kev tshem tawm cov cim me me thiab ua kom zoo ib yam, tsis yog - cov lus qhia ua tiav. Qhov tshwm sim saum npoo profile yog qhov zoo tagnrho rau cov kauj ruam tom ntej anodizing, vim nws txhawb nqa zoo adhesion ntawm txheej anodic.
- Anodizing (Hom II, Sulfuric Acid): Ib feem yog ntxuav kom huv si thiab ces muab tso rau hauv ib da dej sulfuric acid electrolyte. Ib qho hluav taws xob tam sim no yog siv, ua rau qhov anode. Cov txheej txheem no loj hlob ib qho kev tswj hwm, ntxeem tau aluminium oxide txheej ntawm qhov chaw. Tom qab ntawd muab tso rau hauv lub tank dyeing (yog tias xav tau xim, xws li dub lossis xiav) thiab tom qab ntawd muab ntim rau hauv dej kub lossis da dej sealant. Cov txheej txheem sealing no hydrates oxide txheej, kaw nws qhov hws, uas ua rau muaj kev txhim kho corrosion thiab locks hauv cov xim. Lub resulting anodic zaj duab xis yog ib qho nyuaj, ruaj, thiab hluav taws xob insulating.
5. Kev soj ntsuam zaum kawg thiab ntim khoom
Qhov ua tiav tiav dhau los ua qhov kev tshuaj ntsuam xyuas zaum kawg. Qhov no suav nrog:
- Dimensional Verification: Siv Coordinate Measuring Machines (CMM) los yog optical comparators validate tag nrho cov tseem ceeb qhov ntev thiab geometric tolerances (flatness, perpendicularity).
- Txheej Thickness Verification: Ib qho eddy tam sim no los yog sib nqus induction gauge yog siv los ntsuas cov anodic txheej thickness, kom nws ua raws li specifications, feem ntau 5-25 µm rau hom II anodizing.
- Kev Ntsuam Xyuas Kev Pom Zoo: Tshawb xyuas cov khoom tsis xws luag xws li khawb, qhov, lossis qhov tsis sib xws ntawm cov xim lossis kev ntxhib los mos.
Thaum dhau tag nrho cov kev kuaj xyuas zoo, lubCNC machining aluminium xuab zeb blast anodized plhaubyog ntim raws li cov kev cai tshwj xeeb, feem ntau siv los tiv thaiv -tarnish thiab anti- cov ntaub ntawv abrasive, thiab npaj rau kev xa khoom.
Hauv kev xaus, kev tsim cov txheej txheem aluminium enclosure yog ntau-theem, cov txheej txheem tswj tau zoo heev. Txhua kauj ruam, los ntawm thawj CAD tsim mus rau qhov kawg anodizing, nws yog ib qho tseem ceeb rau kev ua tiav ib feem uas ua tau raws li cov qauv kev ua tau zoo, ua haujlwm ntev, thiab kev zoo nkauj xav tau hauv kev tshaj lij thiab kev lag luam.
