High-Speed vs. High-Efficiency Milling rau Aluminium Kub Sinks

Raws li kev thov thoob ntiaj teb rau kev ua haujlwm siab thermal daws loj hlob, manufacturersntsej muag siab kom optimizealuminium kub dab dejntau lawm.Cov tsoos high-speed milling dominates kev lag luam, tab sis tshwm sim high-efficiency cov txheej txheem cog lus productivity nce. Txoj kev tshawb no suav cov kev lag luam tawm ntawm cov txheej txheem no siv cov ntaub ntawv machining tiag tiag hauv ntiaj teb, hais txog qhov sib txawv tseem ceeb hauv kev tshawb fawb siv rau cov khoom siv hluav taws xob txias.

Txoj kev

1.Kev sim tsim

●Workpiece:6061-T6 aluminium blocks (150 × 100 × 25 hli)

●Cov cuab yeej:6 hli carbide kawg mills (3-flute, ZrN-coated)

●Control variables:

HSM: 12,000-25,000 RPM, tas li nti load

HEM: 8,000-15,000 RPM nrog kev sib txawv sib txawv (50-80%)

2. Cov ntaub ntawv khaws cia

●Nto roughness: Mitutoyo SJ-410 profileometer (5 ntsuas / workpiece)

● Cov cuab yeej hnav: Keyence VHX-7000 digital microscope (flank hnav > 0.3mm = tsis ua haujlwm)

● Ntau lawm tus nqi: Lub voj voog sij hawm taug qab nrog Siemens 840D CNC cav

Cov txiaj ntsig & Kev Ntsuam Xyuas

1.Nto Zoo

● Method: HSM HEM

● Optimal RPM: 18,000 12,000

●Ra (μm): 0.4 0.7

HSM's superior tiav (p<0.05) correlates nrog txo built-up ntug tsim ntawm elevated speeds.

2.Tool Lub Neej

● HSM cov cuab yeej ua tsis tiav ntawm 1,200 linear meters vs. HEM's 1,800 meters

● Adhesive hnav dominated HSM tsis ua haujlwm, thaum HEM pom cov qauv abrasive

Kev sib tham

1.Cov kev cuam tshuam

●Rau precision siv:HSM tseem zoo dua txawm tias tus nqi siv ntau dua

●High-volume ntau lawm:HEM lub sijhawm 15% nrawm dua lub sijhawm ua haujlwm tom qab ua haujlwm polishing

2. Cov kev txwv

● Tsis suav nrog 5-axis machining scenarios

● Kev sim txwv rau 6 hli cov cuab yeej; Cov kab uas loj dua tuaj yeem hloov cov txiaj ntsig

Xaus

HSM muab cov khoom zoo tshaj plaws rau cov khoom siv hluav taws xob zoo, thaum HEM ua tau zoo hauv kev tsim khoom loj. Kev tshawb fawb yav tom ntej yuav tsum tshawb nrhiav kev sib xyaw ua ke sib txuas ua ke HSM tiav hla nrog HEM roughing.
