CNC txiav tau dhau los ua lub hauv paus hauv kev tsim khoom niaj hnub, muab qhov tseeb, rov ua dua, thiab ua haujlwm zoo rau kev ua ntau yam ntaub ntawv. Aluminium, nrog rau nws lub zog tshwj xeeb tshaj plaws - rau - qhov hnyav piv, corrosion resistance, thiab malleability, yog ib qho ntawm cov hlau feem ntau siv hauv CNC txiav daim ntaub ntawv. Txawm li cas los xij, tsis yog txhua qib txhuas ua tau zoo sib npaug hauv cov txheej txheem cnc machining. Tsab ntawv xov xwm no qhia txog cov tseem ceeb txhuas yam sib xws nrog CNC txiav, lawv cov yam ntxwv ntawm cov khoom, thiab cov kev xav tseem ceeb rau kev ua tiav cov txiaj ntsig zoo.
Wrought Aluminum Alloys: Thawj Cov Neeg Sib Tw rau CNC txiav
Wrought aluminium alloys, uas yog tsim los ntawm cov txheej txheem xws li dov, extrusion, los yog forging (tsis yog casting), yog cov feem ntau siv hauv CNC txiav. Lawv cov qauv zoo sib xws thiab cov khoom siv kho tshuab zoo ib yam ua rau lawv zoo tagnrho rau kev ua haujlwm precision. Hauv qab no yog cov feem ntau wrought aluminium series haum rau CNC ua haujlwm:
1.1 1000 Series Aluminium (Ntshiab Txhuas)
1000 series (piv txwv li, 1100, 1200) muaj cov khoom lag luam ntshiab txhuas (99% + cov ntsiab lus txhuas). Qhov no series yog paub txog nws zoo heev thermal thiab hluav taws xob conductivity, nrog rau siab ductility. Hauv CNC txiav, 1000 series txhuas yog ib qho yooj yim rau tshuab vim nws tsis tshua muaj hardness (Brinell hardness: ~ 20 HB) thiab tsawg ua hauj lwm hardening nyiam. Nws ua kom huv, burr- txiav dawb nrog cov txheej txheem txiav, ua rau nws tsim nyog rau cov ntawv thov xws li cov dab dej kub, cov khoom siv hluav taws xob, thiab cov khoom siv kho kom zoo nkauj. Txawm li cas los xij, nws lub zog tsawg txwv nws siv hauv cov khoom siv.
1.2 2000 Series Aluminium (Copper-Alloyed)
Lub 2000 series (piv txwv li, 2024, 2017) yog alloyed nrog tooj liab, uas ua rau muaj zog thiab zoo qaug zog.

Rau CNC txiav, 2000 series txhuas yuav tsum tau ceev faj xaiv cov cuab yeej thiab machining tsis. Nws hardness siab dua (Brinell hardness: ~ 120 HB tom qab kev kho cua sov) thiab nyiam ua hauj lwm harden txhais tau hais tias carbide txiav cov cuab yeej nrog ntse npoo yog pom zoo kom tiv thaiv cov cuab yeej hnav. Tsis tas li ntawd, siv cov coolants (piv txwv li, dej-soluble roj) yog qhov tseem ceeb los txo cov cua sov thiab tsis txhob muaj qhov tsis xws luag.
1.3 3000 Series Aluminium (Manganese-Alloyed)
3000 series (xws li, 3003, 3105) yog alloyed nrog manganese, muab qhov sib npaug ntawm lub zog, ductility, thiab corrosion kuj. Nrog lub zog tensile ntawm 110-145 MPa thiab Brinell hardness ntawm ~ 40 HB, nws yog ib qho nyuaj tshaj li 1000 series tab sis yooj yim rau tshuab dua 2000 series . 3000 series txhuas yog sib xws nrog tag nrho CNC tej txheej txheem, xws li milling, tig, thiab drilling. Nws yog feem ntau siv rau cookware, tshuaj cia tso tsheb hlau luam, thiab automotive trim qhov chaw, uas yuav tsum tau ib tug ua ke ntawm formability thiab corrosion kuj.
1.4 5000 Series Aluminium (Magnesium-Alloyed)
Lub 5000 series (xws li, 5052, 5083) yog alloyed nrog magnesium, muab zoo heev corrosion kuj (tshwj xeeb tshaj yog nyob rau hauv marine ib puag ncig) thiab siab ductility. Cov koob no tsis yog - cua sov- kho tau, yog li nws lub zog (lub zog tensile: 230-380 MPa) ua tiav los ntawm kev ua haujlwm txias. Nyob rau hauv CNC txiav, 5000 series txhuas yog machinable heev, ua tiav nto tiav (Ra: 0.8-1.6 μm) nrog cov cuab yeej txheem. Nws feem ntau yog siv rau cov khoom siv hauv hiav txwv, cov hlab ntsha siab, thiab cov khoom siv hauv kev tsim kho, qhov uas tiv taus cov dej ntsev los yog cov tshuaj hnyav yog qhov tseem ceeb.
1.5 6000 Series Aluminium (Magnesium-Silicon-Alloyed)
Lub 6000 series (piv txwv li, 6061, 6063) yog ntau yam txhuas series rau CNC txiav. Alloyed nrog magnesium thiab silicon, nws yog cua sov- kho tau, muab qhov zoo sib npaug ntawm lub zog (tensile zog: 276-310 MPa tom qab kho cua sov), machinability, thiab corrosion kuj. Nrog rau Brinell hardness ntawm ~ 95 HB (T6 temper), nws yog ib qho yooj yim rau tshuab nrog ob qho tib si high-ceev steel (HSS) thiab carbide cov cuab yeej, thiab nws exhibits tsawg heev ua hauj lwm hardening. 6000 series yog siv nyob rau hauv ntau yam kev siv, nrog rau cov khoom siv tsheb, hluav taws xob vaj tse, thiab cov qauv tsim. Nws lub peev xwm los ua anodized kuj ua rau nws nrov rau cov khoom zoo nkauj.
1.6 7000 Series Aluminium (Zinc-Alloyed)
7000 series (piv txwv li, 7075, 7050) yog cov khoom lag luam zoo tshaj plaws aluminium, alloyed nrog zinc, magnesium, thiab tooj liab. Nrog lub zog tensile ntawm 570-690 MPa (T6 temper) thiab Brinell hardness ntawm ~ 150 HB, nws yog siv nyob rau hauv siab - kev ua tau zoo daim ntawv thov xws li aircraft tsaws iav, sib tw tsheb Cheebtsam, thiab precision machinery. CNC txiav ntawm 7000 series txhuas yuav tsum tau siv cov txheej txheem machining siab heev: cov cuab yeej carbide nrog cov txheej txheem tshwj xeeb (xws li TiAlN) yog qhov tsim nyog los tiv thaiv kev txiav txim siab, thiab cov tshuab cua txias siab tau pom zoo kom txo cov cuab yeej hnav thiab txhim kho qhov zoo. Vim nws lub zog siab, nws kuj yuav xav tau kev txiav qeeb qeeb los tiv thaiv cov cuab yeej chipping.
Yam tseem ceeb cuam tshuam rau CNC txiav ntawm Aluminium
Txhawm rau ua tiav cov txiaj ntsig zoo thaum txiav aluminium nrog CNC tshuab, ntau yam yuav tsum tau xav txog:
Alloy xaiv: Raws li tau teev tseg saum toj no, wrought aluminium series (tshwj xeeb tshaj yog 6000 thiab 5000) yog qhov tsim nyog rau CNC txiav ntau dua li cam khwb cia txhuas vim lawv cov qauv sib xws thiab kev ua haujlwm.
Khoom siv: Carbide cov cuab yeej nyiam dua HSS cov cuab yeej rau feem ntau cov txhuas alloys, vim lawv muaj kev hnav siab dua thiab tuaj yeem tiv taus kev txiav nrawm dua. Rau siab - zog alloys (xws li, 7075), coated carbide cov cuab yeej (TiAlN, TiCN) raug pom zoo.
Txiav Parameters: Txiav ceev, pub tus nqi, thiab qhov tob ntawm kev txiav yuav tsum tau ua kom haum rau cov aluminium alloy. Piv txwv li, 6061 txhuas tuaj yeem txiav ntawm qhov nrawm ntawm 1500-3000 m / min, thaum 7075 xav tau qeeb qeeb (800-1500 m / min) los tiv thaiv cov cuab yeej puas.
Kev siv Coolant: Cov coolants yog qhov tseem ceeb los txo cov cua sov, lubricate qhov chaw txiav, thiab tshem tawm cov chips. Dej- cov kua dej ua kua dej feem ntau yog siv rau txhuas, vim tias lawv siv tau zoo thiab raug nqi - zoo.
Tshuab Rigidity: CNC tshuab nrog siab rigidity thiab stability yog yuav tsum tau los tuav lub txiav quab yuam generated, tshwj xeeb tshaj yog thaum ua high - zog aluminium alloys. Qhov no ua kom qhov tseeb thiab tiv thaiv kev vibration - vim qhov tsis xws luag.
