Qee lub tuam txhab txiav cov cuab yeej txawv teb chaws tau ntsib ntau xyoo ntawm txoj kev loj hlob thiab muaj cov khoom lag luam paub daws teeb meem hauv ntau qhov chaw tseem ceeb, xws li kev lag luam tsheb, kev lag luam hluav taws xob, kev lag luam aerospace, kev lag luam kho mob thiab kev lag luam pwm. Qee lub lag luam hauv tsev tau pib lig, tab sis tsim tau sai. Lawv cov khoom tau maj mam siv rau ntau yam kev lag luam, thiab lawv tuaj yeem muab cov kev daws teeb meem zoo rau kev lag luam. Cov kev daws teeb meem rau qhov chaw hauv ntau qhov chaw tau piav qhia hauv qab no.

4. Walter cov kev daws teeb meem rau kev lag luam aviation
Qhov kev thov rau titanium alloy cov ntaub ntawv nyob rau hauv kev lag luam aviation yog loj hlob ib hnub twg, thiab cov kws txawj kwv yees tias nws yuav nce los ntawm qhov nruab nrab ntawm 20% nyob rau hauv tsib lub xyoos tom ntej no. Qhov no yuav yog qhov kev ua si-hloov rau fabs, vim tias kev ua cov titanium alloys feem ntau xav tau lub tshuab ua haujlwm ntev. Walter txhawb nqa nws cov neeg siv khoom hauv kev lag luam aerospace nrog cov cuab yeej tshiab thiab cov kev paub dav dav, nrog lub hom phiaj ntawm kev ua cov khoom siv titanium hauv kev ua haujlwm tau zoo, raug nqi thiab txuag sijhawm.
Lub dav hlau tsim kev lag luam siv ntau cov titanium alloys, tshwj xeeb tshaj yog cov khoom muaj kev ntxhov siab, thiab cov ntaub ntawv titanium alloy yog dav siv. Cov khoom xws li lub qhov rooj thav duab, tsaws iav mounting brackets, thiab tis attachments feem ntau muaj siab machining ntim, yuav tsum tau ib tug loj npaum li cas ntawm machining nyob rau hauv tus txheej txheem uas deb tshaj machining ntawm lub tiav lawm ib feem. Qhov no feem ntau yog vim muaj coob tus dimples hauv monolithic forgings. Cov phab ntsa lossis hauv qab ntawm ntau qhov sib sib zog nqus thiab ntiav dimples, 5-axis dimples, thiab cov duab plaub feem ntau nyias nyias, yog li nws nyuaj rau zeb, thiab cov kev cai nruj tau muab tso rau hauv kev ua haujlwm ntawm cov khoom siv no. Indexable inserts thiab khoom carbide milling cutters tuaj yeem ua tiav kev lag luam tawm. Kev tsom xam yog nyob rau ntawm cov txheej txheem kev ntseeg siab, vim cov khoom no kim heev. Nyob rau tib lub sijhawm, tus nqi siab ntawm kev ua lag luam tau ua rau qhov kev thov rau kev ua haujlwm siab thiab kev ua haujlwm ntau lawm.
Feem ntau thaum machining titanium alloy cov ntaub ntawv, cov khoom muaj ib tug tsawg thermal conductivity thiab yog nquag rau vibrations, yog li yuav tsum tau ib tug nruj tshuab tswvyim thiab optimized txiav ntug npaj.
Cov kws tshaj lij ua haujlwm ntawm Walter Aerospace Kev Lag Luam hauv Tübingen, Lub Tebchaws Yelemees tuaj yeem muab cov neeg siv khoom nrog cov txheej txheem customized nrog kev ua haujlwm siab tshaj plaws. Qhov tseem ceeb ntawm no yog kom phim cov txheej txheem rau lub tshuab hom thiab muaj peev xwm. Piv txwv li, cov cuab yeej siv tshuab ua haujlwm qis dua tuaj yeem siv los ua kom tiav cov zis ntau tshaj. Simulate thiab txheeb xyuas cov txheej txheem ua ntej xa mus, kom cov neeg siv tuaj yeem paub qhov ua tau zoo, kev lag luam lossis kev ntseeg siab ntawm kev ua haujlwm.
1. Cov kev ntsuam xyuas ntawm txhuas alloys Txij li thaum kev lag luam aerospace muaj qee qhov kev sim tiag tiag ncaj qha thiab tsis muaj cov khoom loj, Walter cov kws tshaj lij feem ntau siv cov khoom zoo tib yam los ua pov thawj qhov kev ua tau zoo ntawm txhua tiam ntawm nws cov khoom siv. Cov khoom no yog ua los ntawm cov khoom lag luam muaj Ti6Al4V (3.7164). Walter kws txawj tsim qhov chaw nrog ntau yam ntawm cov duab dimple uas zoo ib yam lossis zoo ib yam li cov ntawm qhov tseeb. Ntawd yog hais, cov txiaj ntsig kev ua haujlwm tuaj yeem hloov mus rau ib leeg.
Lub hom phiaj yog plaub-hauv-ib lub cuab yeej: M3255 tangential pob kws zeb, M4002 siab noj lub ntsej muag zeb (roughing lag luam), Ti40 khoom carbide lub ntsej muag zeb thiab modular Ti50 interchangeable taub hau ConeFit milling cutters (semi-tiav thiab tiav. kev ua haujlwm). Qhov no yog kev sib xyaw ua ke uas tej zaum yuav xav tau hauv lub neej tiag tiag, piv txwv li thaum machining tsaws iav mounting brackets. Lawv tsim ob hom khoom carbide txheej txheej thiab macro-grooves thiab micro-grooves tshwj xeeb rau titanium alloy machining. M3255 thiab M4002 milling cutters feature indexable inserts ua los ntawm Walter tus tshiab WSM45X tej cuab yeej cuab tam. Cov txheej txheem zoo tshaj plaws rau ISO S thiab ISO M daim ntawv thov yog CVD txheej, uas muaj zog heev.
