Lo lus nug 1: Dab tsi yog thawj cov qauv kev tsim khoom rau precision-txiav aluminium Cheebtsam hauv engineering?
Teb:
Precision txiav ntawm txhuas ua haujlwm peb txoj kev ua haujlwm:
CNC Milling: TAM SIM NO ± 0 {{{. 01 hli geadeties zoo li turbide up mills, zoo heev} rpm) minimizes burr tsim.
Laser txiav: Fiber ntau (1,070 nm wavelength) txiav cov ntawv kom txog 25 hli tuab nrog kerf dav<0.2 mm, but require nitrogen assist gas to prevent oxidation.
Hlau Edm: Siv Brass Hlau (ø0 .}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}! Qeeb (2-10 mm² / min) tab sis kev ntxhov siab pub dawb.
Txhua txoj kev haum cov ntawv thov tshwj xeeb: CNC rau ntau ntau lawm, lasers rau cov ntawv nyias nyias, thiab EDM rau cov khoom tawv tawv {}}
Lo lus nug 2: Cov khoom siv alloy cuam tshuam ua kom muaj qhov tsis muaj tseeb?
Teb:
Txhuas alloys tau thov cov tswv yim txiav cov tswv yim:
1xxx series (ntshiab al): Mos / nplaum; Yuav tsum muaj cov cuab yeej polished thiab siab sua teb cov ces kaum (35℃+) los tiv thaiv cov nti vuam .
2xxx series (cu alloys): Abrasive; PCD cov cuab yeej pom zoo nrog kev txiav nrawm ntawm 200-300 m / min.
6xxx series (mg-si): Ntsuas tes ua tau zoo; 2- raj taws kawg}}}}}}}} rpm ua kom zoo tshaj plaws.
Kev xaiv coolant yog qhov tseem ceeb: mql tshuab txo thermal distortion hauv 5xx alloys tab sis dej nyab kom tiv thaiv kev ua haujlwm hnyav.
Lo lus nug 3: Cov cuab yeej ua cas ntawm cov metrology cov cuab yeej kom ua kom muaj qhov tseeb nyob rau hauv precision aluminium qhov chaw?
Teb:
Niaj hnub nimno Tswjhwm Tswj Ua ke:
Cmms: Ntsuas 3D yam rau ± 0 {{{{}} 00 001 mm, siv cov kev kuaj xyuas rub tawm rau kev khawb.
Kho qhov muag: Txheeb xyuas cov ntug dej num (e {{{{0} g ., xov zoo {}
Nto Roughnness Testers: Quantifye RA qhov tseem ceeb tshaj tawm-machining (tseem ceeb rau cov chaw ntim khoom) .
Statistical process control (SPC) tracks Cp/Cpk values >1 {. 33 kom muaj 6 tus qauv sigma nyob hauv cov ntawv thov hauv tsheb.
Lo lus nug 4: Cov tsav tsheb raug nqi nyob rau hauv precision aluminium feem ntau lawm?
Teb:
Cov nqi tseem ceeb muaj xws li:
Cov Khoom Siv Pov Tseg: NESTING Software txo cov scrap los ntawm 20% rau<8% in sheet cutting.
Tuam Kev Hnav: Cov alloys nyuaj (e {{.}}}}}}}
Zog Siv: Laser txiav 8-12 kw / h, thaum lub sij hawm Waasjets siv 30-50 kw / h rau cov ntu tuab {}}
Batch ntau lawm (500+ units) feem ntau ntawm cov nqi qis dua) feem ntau los ntawm kev txo qis cov cuab yeej thiab cov khoom txo qis.
Lo lus nug 5: Tom qab ua haujlwm li cas txhim kho precision aluminium Cheebtsam?
Teb:
Cov kauj ruam tseem ceeb tom qab:
Kev ua tshoob: Automated robotic tshuab tshem tawm micro-burrs (<0.05 mm) using ceramic brushes.
Txoj kev: Hom III Hardcoat Ntxiv 50-100 μm oxide txheej, txhim kho cov hnav tsis kam (hv} .
Kev ntxhov siab tau txais kev ntxhov siab: Kev kho mob cua sov ntawm 150℃rau 4 teev ruaj khov qhov ntev hauv cov qauv txheej txheem .
Kev siv hluav taws xob tuaj yeem txo qis ntawm cov npoo av saum npoo av los ntawm 60%, tseem ceeb rau kev kho mob cog.
