Kev tsim khoom ntxiv muaj kev ywj pheej los tsim cov duab nyuaj, tab sis hauv kev xyaum, kev ua tiav saum npoo feem ntau yuav tsum muaj kev txwv tsim. Txawm hais tias kev txhim kho cov hmoov hlau zoo, kev ua kom zoo ntawm kev tsim cov kev taw qhia thiab cov txheej txheem tsis tuaj yeem txhim kho qhov zoo ntawm cov khoom siv ntxiv rau qee qhov, qhov teeb meem ntawm qhov chaw roughness tsis tuaj yeem daws tau tag nrho. Yog li ntawd, tom qab ua tiav ntawm 3D luam tawm qhov chaw yog qhov tsim nyog. Cov txheej txheem tseem ceeb tom qab ua tiav tam sim no suav nrog kev ua tiav thiab machining. Cia peb ua tib zoo saib cov txheej txheem no.
Ftxheej txheem inishing
Txoj kev ua tiav feem ntau suav nrog kev tuav polishing, sandblasting, lossis CNC sib tsoo. Qhov zoo ntawm phau ntawv polishing feem ntau nyob ntawm tus neeg teb xov tooj qhov kev paub dhau los, nrog kev rov ua haujlwm tsis zoo thiab sib xws, cov nqi zog siab thiab lub sijhawm, thiab cov plua plav tawm thaum polishing yog qhov tsis zoo rau tib neeg kev noj qab haus huv. Tsis tas li ntawd, sandblasting thiab CNC sib tsoo muaj cov khoom siv tsis zoo rau cov khoom siv nrog cov txheej sab hauv thiab cov txheej txheem ntxeem tau, yog li lawv feem ntau siv los ntxuav thiab polishing txheej txheej ntawm qhov chaw thiab tshem tawm cov txheej oxide.
Rau cov txheej txheem nyuaj uas yuav tsum muaj qhov zoo ntawm qhov chaw: Ra yog 0.8μm ~ 1.6μm, cov txheej txheem tiav ntsib cov teeb meem loj. Ntxiv nrog rau cov txheej txheem saum toj no, muaj cov duab-adaptive sib tsoo, laser polishing, tshuaj polishing, thiab abrasive flow machining.
Puab Adaptive Sib Tsoo
Shape Adaptive Sib Tsoo (SAG) yog cov txheej txheem tshiab rau kev ua haujlwm dawb ntawm cov khoom siv nyuaj xws li ceramics thiab cov hlau tawv. Lub semi-elasticity ntawm lub cuab yeej enables ductile hom sib tsoo nrog ib tug siab nto tag txawm tias cov khoom qis zog ntawm cov khoom siv machining. Nws tau tshaj tawm tias qee cov kws tshawb fawb siv cov duab hloov kho txoj kev sib tsoo ntawm kheej kheej hloov pauv lub taub hau kom polish qhov dawb ntawm titanium alloy 3D luam tawm qhov chaw. Cov txheej txheem tsis zoo ntawm qhov chaw tsim khoom ntxiv raug tshem tawm los ntawm kev ntxhib polishing thiab polishing zoo, thiab qhov kawg ntawm qhov roughness Ra yog tsawg dua 10 nm.
Laser polishing
Laser polishing siv lub zog loj laser beam kom rov yaj cov khoom nto ntawm qhov chaw kom txo tau qhov roughness. Tam sim no, qhov nto roughness Ra ntawm laser polished qhov chaw yog li 2 ~ 3μm. Vim tias tus nqi siab ntawm cov khoom siv laser polishing, nws tsis tau siv dav hauv qhov tseeb 3D luam ntawv tom qab ua tiav.
Chemical polishing
Ib qho txiaj ntsig ncaj qha ntawm cov tshuaj polishing yog micro-roughness smoothing thiab polishing tsim, nrog rau kev sib xyaw ua ke ntawm txheej txheej sab saud. Hauv kev tsim khoom me me, kev tshem tawm cov qauv hollow lossis xoob kheej kheej txheej ntawm qhov chaw nrog cov qauv hollow muaj qhov cuam tshuam loj. Los ntawm kev siv tshuaj polishing thiab electrochemical polishing, qhov roughness ntawm cov khoom cog tau raug txo los ntawm 6 ~ 12 μm rau 0.2 ~ 1 μm.
Abrasive Flow Machining
Abrasive Flow Machining (AFM) yog cov txheej txheem sab hauv txheej txheej txheej txheem los ntawm kev ntws cov kua dej abrasive los ntawm kev ua haujlwm. Cov kua dej no feem ntau yog khov heev thiab muaj qhov sib xws ntawm putty lossis mov paj. AFM tuaj yeem ua kom du thiab txhuam qhov chaw ntxhib thiab yog tsim los rau deburring, polishing nto, sib sau radii, thiab txawm tshem tawm cov khoom. Cov khoom ntawm AFM ua rau nws zoo tagnrho rau cov chaw sab hauv, grooves, qhov, kab noj hniav, thiab lwm qhov chaw uas nyuaj mus cuag los ntawm lwm cov txheej txheem polishing lossis sib tsoo.
Hmoov txaj fusion tshuab ua rau qhov zoo tshaj plaws saum npoo zoo ntawm cov txheej txheem hlau ntxiv. Ntxiv nrog rau cov txheej txheem saum toj kawg nkaus, nws yog qee zaum tsim nyog rau tshuab qhov tseem ceeb. Ob txoj kev ua haujlwm tom qab no tau siv dav hauv 3D luam ntawv pwm daim ntawv thov. Cia peb tos ntsoov rau qhov yooj yim thiab siv tau zoo ntawm cov txheej txheem machining yav tom ntej!
JR tsis tuaj yeem muab cov hlau 3D luam ntawv nkaus xwb, peb kuj muaj cov kws tshaj lij CNC ua lub Hoobkas, uas tuaj yeem muab kev ua tiav ntawm cov hlau luam ntawv tom qab.
