Tsis yog-txheej txheem CNC machining, tus yam ntxwv los ntawm "ib zaug-daim lossis me-batch ntau lawm, tshwj xeeb qhov ntev, thiab siab precision yuav tsum," tau dhau los ua qhov kev sib tw hauv kev lag luam. Kab lus no yuav siv qhov kev hloov kho ntawm aluminium alloy qhov chaw rau cov khoom siv kho mob ua piv txwv, nthuav tawm cov teeb meem tseem ceeb thiab cov kev daws teeb meem hauv kev tsis yog -tus qauv machining, muab cov ntaub ntawv siv rau machining ntawm cov khoom zoo sib xws. Nrog 10 xyoo ntawm kev paub tshwj xeeb hauv kev tsis yog -tus qauv CNC machining, peb txhawb kev hloov kho rau ntau yam kev lag luam suav nrog kev kho mob, tsheb, thiab hluav taws xob, thiab muab kev daws teeb meem dawb machining tsim.
I. Case Background
Cov neeg siv khoom xav tau: Customized aluminium alloy txuas cov raj rau kev kho mob lub tshuab ua pa, ua los ntawm 6061 aluminium alloy, 300mm nyob rau hauv ntev, φ20mm nyob rau hauv txoj kab uas hla, 2mm nyob rau hauv phab ntsa thickness, kam rau ua ± 0.02mm, deg roughness Ra Less tshaj los yog sib npaug zos rau 0.4μm, yuav tsum withstand 0.6MPa qhov loj ntawm huab cua.
- Cov Ntsiab Lus Mob Rau Cov Neeg Siv Khoom: Cov tuam txhab koom tes yav dhau los tau ntsib cov khoom seem ntau li 15% vim yog deformation thiab substandard precision thaum nyias - phab ntsa machining, uas ua rau kev xa khoom qeeb.
II. Core Machining Challenges
1. Nyias-cov qauv phab ntsa ua rau deformation: 2 hli nyias phab ntsa yog yooj yim khoov thiab vibrated nyob rau hauv txiav quab yuam, ua rau qhov sib txawv ntawm qhov loj me.
2. Nyuaj hauv kev tswj xyuas qhov tseeb: Nrog rau qhov ntev - mus rau - txoj kab uas hla ntawm 15: 1, coaxiality yuam kev yuav tshwm sim thaum drilling thiab tig.
3. Cov kev xav tau zoo saum npoo: Cov khoom siv kho mob yuav tsum tsis txhob khawb thiab burrs kom tsis txhob muaj kab mob loj hlob.
III. Targeted Solutions
(I) Cov txheej txheem optimization
Kev siv lub tswv yim "roughing-ces-finish + segmented machining" lub tswv yim: Ua ntej, qhov kev sib hloov yog ua tiav (tawm ntawm qhov nyiaj 0.5mm) kom tshem tawm feem ntau ntawm cov khoom siv ntau dhau; Tom qab ntawd, CNC precision tig yog ua nyob rau hauv ntu (0.2 hli lub cuab tam lub vojvoog), nrog rau txhua ntu tsis pub tshaj 50 hli ntev kom txo tau qhov cuam tshuam ntawm kev txiav quab yuam ntawm cov phab ntsa nyias; Thaum kawg, ib qho cuab yeej tho txawv sab hauv yog siv rau kev tho txawv los xyuas kom meej qhov tseeb ntawm sab hauv.
(II) Kho thiab kho cov cuab yeej
- Lub fixture siv lub tes tsho elastic shrink kom tusyees qhwv lub workpiece nto, txo clamping kev nyuaj siab; roj hmab pads yog txuas mus rau qhov chaw sib cuag ntawm lub fixture thiab lub workpiece los tiv thaiv pinching puas.
- Carbide- cov cuab yeej coated yog siv, nrog rau kev txiav ceev ntawm 1000 m / min thiab pub tus nqi ntawm 0.08 mm / r. Emulsion txias yog siv los txo qhov kub thiab txias.
(III) Precision thiab Surface Quality Control
- Dimensional checks yog ua txhua 10 daim thaum machining. Lub tshuab ntsuas kev sib koom tes yog siv los xyuas cov coaxiality thiab sab hauv txoj kab uas hla, thiab cov kev pab cuam tsis raug kho raws li.
- Tom qab ua tiav, kev ntxuav ultrasonic yog siv los tshem tawm cov kua dej uas seem, ua raws li phau ntawv polishing nrog 2000-grit sandpaper. Thaum kawg, anodizing yog ua los txhim kho nto tiav thiab corrosion kuj.
IV. Ua cov txiaj ntsig thiab cov neeg siv khoom tawm tswv yim
Los ntawm cov kev daws teeb meem saum toj no, tag nrho 50 qhov chaw kho kom haum tau raws li cov qauv: dimensional tolerances raug tswj nyob rau hauv ± 0.015mm, coaxiality yuam kev Tsawg dua los yog sib npaug li 0.01mm, nto roughness Ra=0.3μm, thiab tsis muaj leakage tau soj ntsuam thaum lub sij hawm huab cua ntsuas. Cov neeg siv khoom tawm tswv yim qhia txog kev sib sau ua ke ntawm cov khoom, ua tau raws li qhov xav tau ntawm kev siv cov cuab yeej kho mob. Daim ntawv cog lus kev koom tes ntev ntev tau kos npe tom qab, nrog rau kev hloov kho txhua xyoo ntau tshaj 5000 daim.
Tus yuam sij rauCNC machining ntawm cov khoom tsis yog -tus qauvlus dag nyob rau hauv "kev txheeb xyuas qhov tseeb ntawm cov teeb meem + kev tsim qauv tsim." Cov lag luam xav tau lub peev xwm los hloov kho cov kev daws teeb meem, nrog rau siab - cov cuab yeej ua tau zoo thiab pab pawg kws tshaj lij, kom ua tiav qhov tsis yog - tus qauv kev xav tau.
Free Customization Solution: Xa koj cov duab uas tsis yog - tus qauv kos duab, thiab peb yuav rhuav tshem cov teeb meem kev ua haujlwm rau koj, muab kev suav nqi thiab kev npaj rau lub voj voog, thiab lav qhov kev sim siab ntau dhau!
