Ob peb hnub dhau los, daim ntawv tshaj tawm txoj kev loj hlob kaum xyoo ntawm kuv lub teb chaws kev lag luam thiab cov ntaub ntawv xov xwm tau tshaj tawm: Los ntawm 2012 txog 2021, tus nqi ntxiv ntawm kev tsim khoom lag luam yuav nce los ntawm 16.98 trillion yuan mus rau 31.4 trillion yuan, thiab qhov feem ntawm lub ntiaj teb. yuav nce li ntawm 20% mus rau ze li 30%.… Txhua yam ntawm dazzling cov ntaub ntawv thiab kev ua tiav tau cim tias kuv lub teb chaws tau coj mus rau hauv keeb kwm dhia los ntawm "lub zog tsim khoom" mus rau "lub zog tsim khoom".
Cov khoom tseem ceeb ntawm cov cuab yeej tseem ceeb feem ntau yuav tsum muaj cov khoom ntawm lub teeb yuag, siab zog, kub tsis kam, corrosion kuj, hnav tsis kam, thiab lwm yam, thiab cov khoom siv ib txwm ua tsis tau raws li qhov yuav tsum tau ua.Nrog rau kev txhim kho kev tshawb fawb thiab thev naus laus zis, cov ntaub ntawv tshiab xws li titanium alloys, nickel alloys, high-performance ceramics, ceramic-reinforced metal matrix composites, thiab fiber-reinforced composites tseem tshwm sim.Txawm hais tias cov ntaub ntawv no tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov khoom tseem ceeb, kev ua haujlwm nyuaj heev tau dhau los ua ib qho teeb meem, thiab nws kuj yog ib qho teeb meem uas cov chaw tshawb fawb tshawb fawb thoob ntiaj teb tau sim lawv qhov zoo tshaj plaws los daws.
Raws li kev siv thev naus laus zis tshiab los daws qhov teeb meem no, ultra-high-speed machining muaj kev cia siab los ntawm kev tsim khoom lag luam.Lub npe hu ua ultra-high-speed machining technology yog hais txog lub tshuab machining tshiab uas hloov cov machinability ntawm cov ntaub ntawv los ntawm kev ua kom ceev machining, thiab txhim kho cov khoom tshem tawm tus nqi, machining raug thiab machining zoo.Ultra-high-speed machining ceev yog ntau tshaj 10 npaug sai dua li cov tsoos machining, thiab cov khoom raug tshem tawm ua ntej nws deformed thaum lub sij hawm ultra-high-speed machining txheej txheem.Pab pawg tshawb fawb ntawm Southern University of Science thiab Technology tau pom tias thaum lub sijhawm ua haujlwm ceev nce mus txog 700 mais ib teev, qhov "nyuaj-rau-txheej txheem" tus yam ntxwv ntawm cov khoom ploj, thiab cov khoom siv "tig nyuaj rau kev yooj yim".
Titanium alloy yog ib qho "nyuaj-rau-tsim khoom", uas yog hu ua "chewing gum" nyob rau hauv cov khoom.Thaum lub sij hawm ua, nws yuav "lo rau riam" zoo li zom cov pos hniav sticks rau cov hniav, tsim ib tug "chipping qog".Txawm li cas los xij, thaum kev ua haujlwm nrawm nce mus rau qhov tseem ceeb, titanium alloy yuav tsis "lo rau riam", thiab yuav tsis muaj teeb meem tshwm sim hauv kev ua ib txwm ua xws li "workpiece hlawv".Tsis tas li ntawd, kev puas tsuaj ntawm cov txheej txheem kuj tseem yuav raug tshem tawm nrog kev ua kom nrawm, tsim cov nyhuv ntawm "cov tawv nqaij puas".Ultra-high-speed machining thev naus laus zis tuaj yeem tsis tsuas yog txhim kho machining efficiency, tab sis kuj txhim kho machining zoo thiab precision.Raws li ultra-high-speed machining theories xws li "cov ntaub ntawv embrittlement" thiab "kev puas tsuaj rau daim tawv nqaij", tsuav yog qhov tseem ceeb machining ceev tau mus txog, qhov nyuaj-rau-tshuab cov yam ntxwv ntawm cov khoom yuav ploj mus, thiab cov khoom siv. yuav yooj yim npaum li "ua ib daim nqaij los daws tus nyuj".
Tam sim no, daim ntawv thov loj loj ntawm ultra-high-speed machining thev naus laus zis tau nyiam ntau yam.Lub International Academy of Production Engineering hais txog ultra-high-speed machining thev naus laus zis raws li cov kev tshawb fawb tseem ceeb ntawm lub xyoo pua 21st, thiab Nyiv Advanced Technology Research Association kuj tau teev cov tshuab thev naus laus zis thev naus laus zis ua ib qho ntawm tsib cov khoom siv niaj hnub no.
Tam sim no, cov ntaub ntawv tshiab tau tshwm sim tas li, thiab ultra-high-speed machining thev naus laus zis yuav tsum tau daws cov teeb meem ua tiav thiab coj lub kiv puag ncig mus rau qhov ua tau zoo thiab ua tau zoo ntawm "cov ntaub ntawv nyuaj rau tshuab", thaum ultra-siab. -Speed tshuab cov cuab yeej hu ua "industrial niam machines" yuav tsum tau los ua breakthroughs "Nyem-rau-cov txheej txheem cov ntaub ntawv" yog ib tug haib cuab tam rau kev ua nyuaj.Nyob rau hauv lub neej yav tom ntej, ecology ntawm ntau lub lag luam tseem yuav hloov raws li qhov tshwm sim, thiab ntau qhov chaw tshiab ntawm kev loj hlob sai yuav tshwm sim, yog li hloov pauv cov qauv kev lag luam uas twb muaj lawm thiab txhawb kev txhim kho ntawm kev tsim khoom lag luam.
