Laser Drilling Technology rau siab -Titanium Alloy Machining

Titanium alloys, nrog lawv cov Vickers siab hardness thiab thermal conductivity tsawg, tam sim no tseem ceeb cov kev cov nyom rau cov pa mechanical drilling, nrog rau cov cuab yeej siv ceev, hnyav thermal deformation thiab tsis zoo machining precision. Laser drilling, siv qhov zoo ntawm tsis yog -kev sib cuag, kev ua haujlwm siab, thiab kev ua haujlwm siab, tawg los ntawm cov teeb meem ntawm titanium alloy precision machining. Nws tuaj yeem pab txhim kho qib siab -kev tsim khoom kawg ntawm micron- qib thiab kev tsim khoom ntse.

 

 

Laser drilling tsom lub siab -zog- laser beam ceev ntawm titanium alloy nto, ua rau cov khoom tam sim ntawd yaj, vaporize, thiab tig mus rau hauv cov ntshav. Cov seem raug tshem tawm los ntawm qhov siab - siab roj los ua qhov siab - qhov tseeb. Nws qhov xwm txheej siab tshaj nyob hauv kev tswj hwm ntawm lub zog thiab cov txheej txheem ua haujlwm, nrog rau kev ua haujlwm tseem ceeb hauv iteration ntawm mem tes thev naus laus zis thiab kev ua kom zoo ntawm kev ua haujlwm.

 

Pulse thev naus laus zis tau dhau los ntawm nanosecond mus rau picosecond thiab femtosecond ultra- lasers ceev. Nws ua tiav cov khoom siv vaporization ncaj qha, txo cov cua sov- thaj chaw cuam tshuam (HAZ) kom qis dua 5μm thiab zam qhov tsis xws luag xws li cov txheej txheem rov qab. Infrared femtosecond laser ua ntawm titanium alloy ua rau lub qhov phab ntsa roughness (Ra), qhov txoj kab uas hla qhov tseeb ntawm ± 2μm, thiab rov muab tso rau qhov tseeb ntawm ± 1.5μm, ua tau raws li qhov yuav tsum tau ua ntawm siab -kawg manufacturing.

 

Cov hom kev ua haujlwm tseem ceeb yog percussion drilling thiab trepanning drilling:

Percussion drilling tswj qhov tob los ntawm pulses, ua rau nws muaj txiaj ntsig zoo rau kev tsim khoom loj ntawm micro- qhov;

 

Trepanning drilling cia siab rau cov kev sib raug zoo ntawm lub voj voog, ua tiav lub qhov zoo tshaj plaws thiab cov phab ntsa zoo, thiab tuaj yeem ua cov txheej txheem siab - qhov precision nrog qhov sib piv ntau dua 50: 1. Ua ke nrog 5-axis linkage dynamic focusing thiab CCD visual positioning thev naus laus zis, nws tseem tuaj yeem ua cov qhov tshwj xeeb zoo li lub qhov ntawm txoj kab nkhaus thiab ntawm cov kaum sab xis qis dua lossis sib npaug li 45 degree, nrog qhov sib txawv ntawm lub qhov axis thiab cov kab tsim ib txwm tsawg dua lossis sib npaug li 1.5 degree.

Piv nrog rau cov tsoos mechanical drilling thiab hluav taws xob tawm machining (EDM), laser drilling ua plaub- hauv- ib qho kev sib tw ntawm "precision, efficiency, yooj, thiab ib puag ncig tus phooj ywg" hauv titanium alloy precision machining, nrog rau kev zoo. Cov ntsiab lus tseem ceeb yog ob qhov kev sib tw hauv ultra- ua haujlwm siab thiab raug:

 

High-faiv fab fiber ntau lasers ua ke nrog 200kHz siab- zaus pulses pab ib leeg- qhov ua haujlwm hauv 0.05-0.5 vib nas this, 10-1000 npaug ntau dua EDM. Lub peev xwm ntau lawm ntawm aero-engine turbine hniav ua yog nce ntau dua 300%. Qhov chaw tsom qhov loj me me yog tsawg dua lossis sib npaug li 15μm, nrog lub qhov taub qhov tseeb ntawm ± 15μm thiab roundness Ntau dua lossis sib npaug li 95%, ua kom ruaj khov ntawm micro-qhov xws li 0.001mm txog 1mm, uas yog qhov tseeb dua li kev ua haujlwm ib txwm muaj.

 

Tsis yog-kev sib cuag thiab cov khoom siv tag nrho adaptability nthuav dav daim ntawv thov ciam teb: Tsis muaj kev txiav quab yuam-induced deformation, haum rau titanium alloy nrog thicknesses ntawm 0.1-50mm; Kev txawj ntse hloov ntawm wavelengths, lub zog gradient them nyiaj, thiab 0.2-0.8MPa siab-siab auxiliary gas paub burr-dawb thiab kev ntxhov siab-concentration-free los ntawm-qhov ua, nrog HAZ Tsawg dua los yog sib npaug rau 50μm, haum rau titanium alloys thermal tivthaiv.

 

Kev txawj ntse thiab kev tsim ntsuab ua ke nrog kev txhim kho kev lag luam: Cov khoom siv sib xyaw ua ke AI thiab tiag - lub sijhawm saib xyuas kom ua kom zoo dua qub, ua kom lub qhov taub ntawm qhov tsim nyog tus nqi rau 98% thiab txo cov sij hawm debugging los ntawm 90%; Siv qhov tsawg kawg nkaus lubrication (MQL) los yog supercritical CO₂ es tsis txhob txiav cov kua yuav txo tau cov dej khib nyiab ntau tshaj 90%, nrog ib tug electro- kho qhov muag conversion efficiency ntau tshaj 30% thiab chav tsev siv zog txo los ntawm 60%, ua raws li ob lub hom phiaj carbon thiab ib puag ncig yuav tsum tau ntawm siab - kawg manufacturing.

 

 

Daim ntawv thov kev loj hlob ntawm laser drilling thev naus laus zis tau hloov kho cov txheej txheem tsim khoom ntawm titanium alloy cov khoom hauv aerospace, cov khoom siv kho mob, lub zog tshiab, thiab lwm yam kev lag luam, dhau los ua cov txheej txheem kev txhawb nqa loj rau kev tsim cov khoom tseem ceeb.

 

Nyob rau hauv lub tshav dav hlau, cov cuab yeej no tawg los ntawm kev tsim cov kev txwv ntawm kub- kawg Cheebtsam: Femtosecond laser ua cov cua txias qhov nyob rau hauv titanium alloy turbine hniav nrog thermal barrier coatings tsis txhob txheej puas, txhim kho cov uniformity ntawm cua txias ntws thiab cav thermal efficiency, ncua cov hniav lub neej, thiab txhim khu kev ua hauj lwm efficiency ntawm daim tawv nqaij rejuvenation. lub teeb yuag.

 

Hauv cov khoom siv kho mob, nws nteg lub hauv paus ruaj khov rau cov tshuaj precision: Peb - qhov ntev los ntawm - qhov sib txuas ntawm orthopedic implants accelerates osseointegration, micro-groove processing ntawm cardiovascular stents txhim kho lub neej qaug zog, thiab micro- cov txheej txheem luv luv ntawm cov txheej txheem osgle postoperative hnov tus nqi rov qab.

Nyob rau hauv lub zog tshiab lub tsheb thiab cov neeg siv khoom siv hluav taws xob, nws txhawb nqa cov khoom sib sib zog nqus thiab kev ua haujlwm tau zoo: Kev ua haujlwm ntawm cov roj teeb hluav taws xob ua rau txo qis slag residue thiab luv luv-circuit txaus ntshai, thiab micro- qhov ua ntawm hydrogen roj cell bipolar daim hlau ua kom muaj peev xwm ntau lawm; Kev ua ntawm foldable npo hinges ua tiav qhov hnyav txo thiab lub neej ntev folding, thiab kev ua haujlwm ntawm cov lus hais hauv xov tooj ntawm tes nruab nrab thav ntawv kom ruaj khov acoustic kev ua tau zoo.
