Cov Case: GH4169 siab - kub alloy alloy alloy alloy alloy alloy alloy alloy alloy alloy alloy alloy alloy
Txhawm rau txhim kho kev ua tau zoo ntawm cov cav tshiab, ib lub tshuab tsim khoom siv dav hlau tsim kom zoo dua cov hniav sib zog ua haujlwm. Lub hom phiaj yog txhawm rau txo cov hniav roughness ntawm RA 3.1μm rau RA 3.1μm rau RA 0.51μm, thiab tib lub sijhawm ua kom tiav qhov ua tau 4.5% nce rau hauv lub cav ntxiv. The processing object is a GH4169 high-temperature alloy integral blade with a diameter of 238mm and a thin-walled structure with a chord-thickness ratio of more than 40:1, which is a typical difficult area of low-vibration milling processing technology.
Kev ua cov ntsiab lus mob
Nyias - duab phab ntsa ua cov teeb meem cim cim cim cim: Tsis txaus ntawm cov hniav hniav txhuam ua rau kev co thiab ua kom pom tseeb ntawm cov cim chatationin;
Tsis zoo saum npoo roughness (ra 0.93μm): cuam tshuam rau kev sib tw tom qab ua haujlwm thiab contour raug;
Hniav Txoj Haujlwm Ua Phom: Tuam kev hnav ua rau kev sib txawv;
Unsmooth Hniav Kev Hloov Hlwb: Tsis txaus ib txwm muaj cua txias thiab lubrication, txiav cov kev sib txuam ua kom kub ua rau cov khoom siv tsis zoo.
Npis XusKEV LAWM: Peb - hauv -} ib lub tshuab ntsuab ntsuab
Hauv kev teb rau cov teeb meem saum toj no, bishen tsim kev lag luam thawj multi {ge}} Axis Linkage sim ua cov tshuaj, sib xyaw peb cov thev naus laus zis thev naus laus zis:
1.Qhov kev siv tshuab ua ultrasonic
Txo kev txiav txim siab los ntawm 46% dhau los ntawm high- zaus kev co kom daws tau cov teeb meem ntawm nyias- Cov qauv phab ntsa ua cov cim sib tham ua ke;
Txais cov txheej txheem sab hauv cua txias kub verb
2.supercritical c2 cua txias tshuab (-78 degree)
Tsawg ib puag ncig qhov chaw ib puag ncig txo qhov kub ntawm 42%, inhibits Thermal deformation ntawm GH4169 siab- kub alloy, thiab ua kom zoo dua hniav evoy;
Nrog sab hauv cua txias nplhaib tshuaj tsuag Tawv Pob Taub Hau Milling Cutter, ua kom tshav kub kub tsis txaus thiab nti tshem tawm tau tiav.
3.12l micro -} lubrication thev naus laus zis
Txo kev sib txhuam sib txhuam los ntawm 31% los ntawm nano-}}}}}} Cov roj tawg ntawm cov nyhuv loj heev;
Sab Hauv Txias Channel Tsim Txuas Txuas Lub Neej Lub Neej thiab txo cov zaus ntawm downtime thiab cuab tam hloov.
Machining cov txiaj ntsig sib piv: los ntawm RA 0.93μm rau RA 0.408μm
Tom qab ua raws li cov kev daws teeb meem bishen, qhov chaw ntawm cov hniav uas raug txo los ntawm 56% rau ra 0.408μm, thiab cov contour qhov tseeb yog ruaj khov li 0.04mm. Nyob rau tib lub sijhawm, lub siab - precision hniav ua kev coj ua raws li cov txiaj ntsig hauv qab no:
Txo cov cim sib tham sib tham: tus thin -}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} pa taub muaj cov kab hniav zoo nkauj thiab txhim kho kev sib xyaw ua ke;
Shortened polishing lub sij hawm: Qhov chaw zoo yog ze rau kev ua tiav zaum kawg, thiab kev ua tau zoo ntawm cov post {}}}}};
Nqi ua kom tau zoo: Cov cuab yeej lub neej yog txuas ntxiv los ntawm 25%, thiab cov nqi ua tau zoo dua yog txo los ntawm 18%.
