Machining ntawm Titanium Alloys, Superalloys, thiab Tsis yog -Cov ntaub ntawv hlau
1. Titanium Alloy Machining
Titanium alloys tau siv dav hauv aerospace, kev kho mob, thiab biomedical teb vim lawv lub zog siab - rau - qhov hnyav piv, corrosion resistance, thiab biocompatibility. Txawm li cas los xij, lawv raug cais raws li qhov nyuaj- rau- cov khoom siv tshuab vim tias lawv cov thermal conductivity tsawg, cov tshuaj muaj zog heev, thiab kev ua haujlwm - tawv tawv.
Cov txheej txheem tseem ceeb Machining:
CNC Milling tshuab: Siab- ceev carbide kawg mills feem ntau siv. Dynamic milling cov tswv yim pab txo cov cua sov thiab cov cuab yeej hnav. Piv txwv li, spindle ceev mus txog 18,000 rpm tuaj yeem ua tiav qhov siab ntawm ± 0.02 hli hauv Qib 5 titanium.
Tig: Yuav tsum muaj kev teeb tsa nruj thiab cov cuab yeej ntse. Dynamic tig txoj kev yog siv kom ruaj khov txiav quab yuam thiab tsis txhob sib tham, tshwj xeeb tshaj yog nyob rau hauv hloov pauv titanium Cheebtsam.
Drilling thiab tho txawv: Siv cov cuab yeej ntse carbide, siab - lub siab txias (Ntau dua lossis sib npaug ntawm 70 bar), thiab cov nqi pub tsawg yog qhov tseem ceeb los tiv thaiv overheating thiab xyuas kom meej qhov tseeb.
Helical Milling: Siv tau rau kev ua haujlwm roughing, faib kev txiav siab sib npaug thiab txo cov cuab yeej hnav.
5-Axis Machining: Pab kom cov geometries nyuaj thiab txo lub sijhawm teeb tsa, tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv kev tsim kho aerospace thiab kev kho mob cog cog.
Coolant thiab Tooling:
emulsion los yog hluavtaws coolants nrog siab lubricity yog nyiam.
Internal coolant xa thiab vibration -dampening tool tuav txhim kho nto tiav thiab lub neej lub cuab tam.
Hybrid damping tuav tuaj yeem txo kev vibration txog li 40%, ua kom daim iav-zoo li ua tiav ntawm nyias- cov phab ntsa.
2. Superalloy Machining (piv txwv li, GH4169, GH2747)
Superalloys, tshwj xeeb tshaj yog npib tsib xee-raws li alloys xws li GH4169 thiab GH2747, yog qhov tseem ceeb nyob rau hauv siab -kub siv xws li roj turbines, dav hlau cav, thiab aerospace Cheebtsam. Lawv nthuav tawm kev nkag siab zoo heev, tiv thaiv oxidation, thiab lub zog ntawm qhov kub siab, tab sis nyuaj heev rau tshuab.
Cov Kev Sib Tw Tseem Ceeb:
Siab txiav quab yuam thiab kub
Cov cuab yeej hnav nrawm nrawm vim ua haujlwm hnyav
Tsawg thermal conductivity ua rau cov cua sov concentration ntawm cov cuab yeej ntug
Machining Strategies:
Cov cuab yeej siv: Siv cov coated carbide, ceramic, lossis cubic boron nitride (CBN) cov cuab yeej
Tsawg txiav ceev: Kom txo cov cua sov tsim
High -pressure Coolant: Qhov tseem ceeb rau nti khiav tawm thiab cua txias
Kev teeb tsa ruaj khov: Rigid fixtures thiab cov cuab yeej luv luv overhangs kom txo qis kev vibration
Txheej txheem txheej txheem:
Tig thiab Milling: Feem ntau ua raws li kev tswj xyuas nrog cov cuab yeej ua haujlwm zoo thiab cov dej txias ntws
Forging thiab Thaum tshav kub kub kho: Ua ntej machining, superalloys feem ntau forged ntawm qhov kub thiab txias (piv txwv li, 950-1300 degree) thiab tau txais kev daws teeb meem + kev laus kev kho mob los txhim kho machinability thiab mechanical zog.
Simulation thiab optimization: Finite element modeling (piv txwv li, DEFORM) yog siv los kwv yees qhov kub thiab txias teb thaum lub sij hawm forging thiab machining
3. Tsis yog -Machining Cov Khoom Siv Hlau
Tsis yog- cov khoom siv hlau xws li yas, ceramics, iav, thiab cov khoom sib xyaw tau siv ntau dua hauv kev lag luam aerospace, electronics, thiab kev kho mob kev lag luam vim lawv lub teeb yuag, corrosion resistance, thiab tailored zog.
