Cov khoom tseem ceeb ntawm cov khoom siv tseem ceeb yuav tsum muaj lub teeb pom kev zoo, lub zog siab, kev kub siab, kev tiv thaiv corrosion, hnav tsis kam, thiab lwm yam khoom, thaum cov khoom siv tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua. Nrog rau txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, cov ntaub ntawv tshiab xws li titanium alloy, nickel alloy, high-performance ceramics, ceramics reinforced metal matrix composites, thiab fiber reinforced composites tau 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, lawv cov kev ua haujlwm yog qhov nyuaj heev los ua ib qho teeb meem, uas cov chaw tshawb fawb tshawb fawb thoob ntiaj teb tau sim daws.
Raws li cov thev naus laus zis tshiab los daws qhov teeb meem no, ultra-high-speed machining yog qhov xav tau los ntawm kev tsim khoom lag luam. Lub npe hu ua ultra-high-speed machining thev naus laus zis yog hais txog kev ua lag luam tshiab uas tuaj yeem hloov pauv cov khoom siv, thiab txhim kho cov khoom tshem tawm tus nqi, machining raug, thiab kev ua haujlwm zoo los ntawm kev txhim kho cov txheej txheem ceev.

Ultra-high-speed machining ceev yog ntau tshaj 10 npaug sai dua li cov tsoos machining ceev, thiab cov ntaub ntawv raug tshem tawm ua ntej deformation tshwm sim nyob rau hauv cov txheej txheem ntawm ultra-high-speed machining. pab pawg tshawb fawb tshawb fawb ntawm Southern University of Science thiab Technology tau pom tias thaum lub sijhawm ua haujlwm ceev nce mus txog 700 km / h, "txhim kho nyuaj" cov yam ntxwv ntawm cov ntaub ntawv ploj mus thiab kev ua cov ntaub ntawv ua "yooj yim tig".
Titanium alloy yog ib qho "nyuaj-rau-cov khoom siv", uas yog hu ua "chewing gum" nyob rau hauv cov khoom. Thaum lub sij hawm ua, nws yuav zoo li "nplaum riam" zoo li zom cov pos hniav lo hniav, tsim "chip qog". Txawm li cas los xij, thaum cov txheej txheem ceev nce mus rau qhov tseem ceeb, cov titanium alloy tsis lo rau riam, thiab muaj. tsis muaj teeb meem tshwm sim nyob rau hauv ib txwm machining xws li workpiece burns. Tsis tas li ntawd, kev puas tsuaj yuav raug cuam tshuam nrog kev nce hauv kev ua haujlwm nrawm, tsim cov nyhuv ntawm daim tawv nqaij puas.
Ultra-high-speed machining thev naus laus zis feem ntau suav nrog kev tshawb fawb ntawm ultra-siab ceev txiav thiab sib tsoo mechanisms, kev tsim tshuab ntawm ultra-high speed spindle units, manufacturing technology ntawm ultra-high speed feed units, manufacturing technology ntawm cov cuab yeej, thiab abrasives rau ultra- high-speed machining, online tsis siv neeg soj ntsuam, thiab tswj tshuab rau ultra-high-speed machining, thiab lwm yam.
