Titanium's tsis zoo thermal conductivity thiab siab tshuaj reactivity ua rau nws yooj yim rau nto defects thaum lub sij hawmCNC machining. Txawm hais tias cov cuab yeej geometry thiab txiav cov ntsuas tsis tau kawm tau zoo, qhov kev ua kom zoo ntawm cov coolant tseem tsis tau siv hauv kev lag luam xyaum. Txoj kev tshawb no (ua hauv 2025) hais txog qhov sib txawv no los ntawm kev txheeb xyuas seb lub hom phiaj ntawm cov khoom xa tuaj yeem txhim kho qhov ua tiav zoo yam tsis muaj kev cuam tshuam txog kev xa khoom.
Txoj kev
1. Kev sim tsim
●Khoom siv:Ti-6Al-4V pas nrig (Ø50mm)
●Khoom siv:5-axis CNC nrog cov cuab yeej txias txias (siab ntau: 20-100 bar)
●Metrics Tracked:
Nto roughness (Ra) ntawm kev sib cuag profileometer
Cov cuab yeej flank hnav siv USB microscope duab
Txiav cheeb tsam kub (FLIR thermal lub koob yees duab)
2. Kev tswj xyuas dua
● Peb qhov kev xeem rov ua dua ib qho kev ntsuas
● Cov cuab yeej ntxig hloov tom qab txhua qhov kev sim
● Ambient kub stabilized ntawm 22 ° C ± 1 ° C
Cov txiaj ntsig & Kev Ntsuam Xyuas
1. Coolant Siab vs. Nto tiav
●Siab (bar):20 5080
●Avg. Rau (μm) :3.2 2.1 1.4
●Tool Wear (mm):0.28 0.19 0.12 ib
High-pressure coolant (80 bar) txo Ra los ntawm 56% piv rau lub hauv paus (20 bar).
2. Nozzle Positioning Effects
Angled nozzles (15 ° rau cov cuab yeej cuab tam) outperformed radial setups los ntawm:
● Txo cov cua sov los ntawm 27% (cov ntaub ntawv thermal)
● Extending cuab tam lub neej los ntawm 30% (hnav ntsuas)
Kev sib tham
1. Cov txheej txheem tseem ceeb
●Chip Evacuation:High-pressure coolant lov chips ntev, tiv thaiv rov txiav.
●Thermal Control:Localized txias minimizes workpiece distortion.
2. Kev txwv tsis pub siv
● Yuav tsum tau hloov kho CNC teeb tsa (tsawg kawg 50 bar twj tso kua mis muaj peev xwm)
● Tsis raug nqi rau cov khoom ntim qis
Xaus
Optimizing coolant siab thiab nozzle alignment ho txhim kho titanium nto tiav. Cov neeg tsim khoom yuav tsum ua qhov tseem ceeb:
● Kho kom zoo dua rau ≥80 bar coolant systems
● Ua cov nozzle qhov chaw sim rau cov cuab yeej tshwj xeeb
Kev tshawb fawb ntxiv yuav tsum tshawb txog hybrid cooling (piv txwv li, cryogenic + MQL) rau hard-to-machine alloys.
