Kev sib tham txog qhov zoo ntawm tsib axis cnc machining rau aviation qhov chaw
Muaj ntau yam teeb meem hauv aerospace tsib axis precision machining. Ua ntej, ib tug loj tus naj npawb ntawm aerospace Cheebtsam yog ua los ntawm ntau yam ntaub ntawv. Lub cav tseem ceeb tshaj plaws hauv kev ua haujlwm dav hlau yog ua los ntawm cov cua sov-resistant hardening alloys uas nyuaj heev rau tshuab. Cov hlau noMuaj ntau tshaj 500000 qhov chaw hauv lub dav hlau, lub dav hlau qhov chaw lossis tsuas yog lub dav hlau ya, thiab ib feem ntawm lawv yuav tsum yog qhov tseeb thiab ruaj khov. Xyuas kom meej tias cov khoom no muaj qhov zoo tshaj plaws thiab tus nqi yog lub hom phiaj tseem ceeb ntawm kev lag luam aerospace.
Teeb meem hauv kev tsim cov khoom siv dav hlau
Muaj ntau yam teeb meem hauv aerospace tsib axis precision machining. Ua ntej, ib tug loj tus naj npawb ntawm aerospace Cheebtsam yog ua los ntawm ntau yam ntaub ntawv. Lub cav tseem ceeb tshaj plaws hauv kev ua haujlwm dav hlau yog ua los ntawm cov cua sov-resistant hardening alloys uas nyuaj heev rau tshuab. Lub thermal conductivity ntawm cov alloys tsis zoo, yog li cov cua sov thaum lub sij hawm ua hauj lwm yuav nyob rau hauv cov cuab yeej. Nickel alloys feem ntau muaj hnub nyoog lossis lwm yam kev kho cua sov thiab yog li nyuaj rau tshuab. Piv nrog rau lwm cov kev lag luam, qhov precision ntawm aerospace qhov chaw yog nruj dua, thiab cov duab geometric ntawm qhov chaw yog ntau qhov nyuaj.
Ntxiv rau cov teeb meem kev ua haujlwm ncaj qha, muaj ntau yam teeb meem tsis ncaj. Ib ntawm lawv suav nrog cov qauv tsim khoom. Zoo li kev lag luam kev kho mob, kev tsim hluav taws xob aerospace yog ib qho ntawm cov kev lag luam tswj hwm tshaj plaws hauv ntiaj teb, thiab nws nyuaj rau ua tau raws li txhua qhov kev xav tau zoo.
Qhov hnyav yog qhov tseem ceeb heev rau lub dav hlau airspace. Qhov sib zog ntawm tus qauv tsim, cov roj tsawg yog siv, yog li cov kws ua haujlwm hauv aerospace feem ntau tsim qhov chaw nrog cov phab ntsa nyias, lattices, webs, thiab lwm yam. Kev lig kev cai, lawv yog machined los ntawm cov khoom cam khwb cia los yog stamped hlau blocks, thiab cov seem ntawm cov seem yog 95 feem pua. Txawm li cas los xij, cov khoom siv qis qis tsis yog qhov teeb meem nkaus xwb. Qhov teeb meem tiag tiag thaum machining xws li qhov chaw yog deformation los ntawm kev txiav quab yuam siab
Yog tias koj nce tus nqi pub thiab txiav qhov tob ntau dhau, tshwj xeeb tshaj yog rau cov nickel alloys, phab ntsa yuav tawg vim kev co los yog deformed vim overheating. Qhov tshwm sim feem ntau yog tias koj txiav tawm me me nti thaum nkag, thiab tag nrho lub sijhawm ua haujlwm tsis yooj yim sua.
Koj tuaj yeem ua dab tsi los txo cov sijhawm ua haujlwm thiab ua tiav kev sib tw nyias-walled aerospace qhov chaw? Thawj qhov koj yuav tsum ua yog txo qhov kev vibration. Cov cuab yeej vibrating tsoo cov phab ntsa nyias thiab khoov lossis tawg. Yog li ntawd, txhawm rau txo qis kev vibration, nws yog qhov zoo dua los txo tus nqi pub, tab sis nce tus naj npawb ntawm cov npoo ntawm cov milling cutter (txawm tias siv ntau lub cutters ntawm lub tshuab dhos). Qhov zoo tshaj plaws txiav cov tswv yim rau nyias-walled aerospace qhov chaw yog pem hauv ntej milling.
Lub tswv yim no siv pub nyob rau hauv qhov kev taw qhia rau cov tsoos milling tswv yim. Qhov no ua rau muaj kev txiav quab yuam tsawg dua, zoo dua qhov tiav, thiab qhov tseem ceeb tshaj plaws, lub milling cutter nkag mus rau hauv cov khoom nrog cov phab ntsa tuab, yog li qhov kev vibration me dua. Txhawm rau tiv thaiv overheating,

Cycloidal machining txoj kev rau txo overheating ntawm aerospace alloys
Overheating ntawm qhov chaw vim tsis zoo cua sov conduction yog ib qho teeb meem ntawm aviation qhov chaw. Lub tswv yim machining kom txo tau cov cua sov yog hu ua cycloidal milling. Nws ua rau kev siv zoo ntawm cov haujlwm ntawm CNC tshuab cuab yeej ua raws txoj kev txiav nyuaj. Lub tswv yim cycloid siv lub tshuab txiav me me (tsawg dua qhov txiav hauv txhua qhov xwm txheej) uas ua raws li txoj hauv kev zoo ib yam li sab qhov projection ntawm lub caij nplooj ntoos hlav ntawm lub dav hlau. Ib qho nkhaus - lub cutter txiav, ces rov qab thaum lub sij hawm thib ob nkhaus, thiab ces txiav cov hlau dua. Lub tswv yim no faib lub sijhawm sib cuag ntawm cov cuab yeej thiab cov khoom kom muaj sijhawm rau cov kua txiav kom txias kom zoo.
Cycloidal tig zoo ib yam li milling, siv cov txiav luv luv thiab ncua sij hawm kom tso cai rau lub coolant ua haujlwm thiab tsis txhob overheating. Lub tswv yim no muaj cov cuab yeej khoob ntau dua li lwm cov tswv yim, tab sis nws tawm tsam qhov cuam tshuam los ntawm kev nce kev txiav ceev thiab pub.
Xaiv cov cuab yeej zoo rau kev ua haujlwm nrawm
Hais txog cov cuab yeej siv tshuab, cov lej tswj tshuab cov cuab yeej tau ua lub luag haujlwm zoo, thiab lawv tau siv dav hauv kev ua txhuas. Ib txoj hauv kev tseem ceeb tshaj plaws los txhim kho machining efficiency yog xaiv cov cuab yeej zoo. Yog hais tias lub softer alloy yog zoo soj ntsuam, thiab ntau manufacturers muab kev daws teeb meem rau txhuas thiab lwm yam alloys. Txawm li cas los xij, ntau cov ntaub ntawv aerospace raug cais tawm, yog li lawv yuav tsum raug xaiv rau ntawm qhov chaw.
Cov txheej txheem ntawm kev xaiv cov cuab yeej siv tau zoo rau cov ntaub ntawv kub-resistant yuav tsum tiv thaiv cov yam ntxwv tsis zoo ntawm cov khoom siv.
Yog li ntawd, lub cuab yeej zoo tshaj plaws yuav tsum muaj kev vibration me me, yuav tsum muaj zog heev, thiab yuav tsum muaj peev xwm tiv taus qhov kub thiab txias kom muaj kev ua haujlwm zoo ib yam thiab muaj txiaj ntsig zoo. Ib qho piv txwv zoo meej ntawm cov cuab yeej rau lub hom phiaj no yog cov cuab yeej pob zeb diamond.
Artificial pob zeb diamond hniav yog ib qho nyuaj thiab ruaj khov dua li cemented carbide hniav, thiab tuaj yeem ua haujlwm ntawm qhov kub thiab txias. Pob zeb diamond machining muaj nws qhov tshwj xeeb, tab sis nws tuaj yeem hloov kho kom tau raws li qhov xav tau ntawm cov tuam txhab aerospace. Ntxiv nrog rau cov cuab yeej pob zeb diamond, cov cuab yeej ceramic kuj tau ua pov thawj tias muaj kev ua tau zoo heev vim tias lawv tuaj yeem ua haujlwm ntawm qhov kub siab tshaj.
Yuav kom txo tau qhov kev vibration ntawm machined qhov chaw, nws yog ib qho tseem ceeb uas yuav tsum tau siv milling cutters nrog ntau txiav npoo thiab ntau ntse ntug kaum. Hom milling cutter no txo lub sij hawm thiab kev ncua deb uas dhau mus ua ntej lub tom ntej txiav ntug hits cov khoom, txo kev co, thiab koj muaj peev xwm ua rau kom txiav tsis ua hauj lwm zoo.
