KEV QHIA TXOG KEV TSIM NYOG RAU ULTRASONIC-ASSITED MACHINING

Ib qho siv hluav taws xob tawm tshiab uas tau txais kev ceeb toom yog ultrasonic-pab machining, los yog-ntau tshaj nruj hais lus-teb ultrasonic co-ua machining, qee zaus raug xa mus los ntawm ib qho yooj yim acronym, UAM. Wikipedia tau tshaj tawm cov lus sau cia hauv RUM nws cov lus qhia ntawm tus txheej txheem. Lub sijhawm yuav qhia rau leejtwg paub.  

Yeej lub tshuab yog ib tug yeej muaj tseeb raws li kev cuam tshuam los ntawm kev ua yeeb yam, kev xav tau. Yeej tseem zoo cov khoom siv yog ib lub voj voog ntawm peb-rau tsib-xais VMC nrog rau kev sib txuam nrawm nrawm thiab siab ntsug kev vibration ntawm lub pob zeb diamond txiav abrasive. Tsis zoo li ultrasonic cav tov (USM) uas tsim cov kua nplaum ua kua nplaum uas npog cov cuab yeej siv thiab workpiece thiab cov khoom siv microchips, UAM siv lub tshuab ua ke nrog polycrystalline pob zeb diamonds uas zom hauv qhov chaw. Cov kev sib hloov ntawm UAM uas tau pab peb sawv cev los ntawm Tongtai yog nce txog 24,000 rpm. Qhov teeb meem ntawm kev vibration yog nyob ntawm 15-45 kHz, thiab lub amplitude siab yog 1-10 μm. Yeej tseem zoo li qhov kev hloov no cov khoom siv nrog kev sib tiv tauj qis zog thiab yog li txo cov rog. Rog txo tsawg npaum li 30-300% nyob ntawm cov khoom. Raws li xws li, feem ntau ntawm cov kev pab cuam ib puag ncig tiav thiab kev ntseeg tiav nrog tus Ra ntawm tsawg dua 0.2μm yog ua tau thiab muaj kev txo qhov hauv qhov chaw thiab kev puas tsuaj, xws li microcracks thiab chipping. Lawm nrog rau qis zog, cuab yeej ntev dua, thiab.

Feem ntau ntawm cov nqe lus nug peb hais txog technology siv cov ntawv sau xws li, "Dab tsi yog qhov zoo tshaj plaws rau ultrasonic-pab tau machining?"

Ib yam li ob leeg peb pab pawg neeg ntawm engineers thiab peb cov neeg muas zaub tau txais kev paub hauv cov kev siv tshuab burgeoning, ntawm no yog cov txheej txheem suab: Ua ntej, xav txog cov ntaub ntawv, xav txog cov neeg uas tau softer tshaj lub pob zeb diamond txiav cuab los yog nyuaj thiab nkig. Piv txwv, zirconium dioxide, aluminium oxide, aluminium alloys, ceramic, silicon thiab tungsten carbide, ntau cov hlau, titanium, Inconel thiab quartz yog tus neeg sib tw zoo rau txoj kev no.

Thib ob-thiab koj yuav muaj cuab kav twv txiaj los ntawm cov tsis muab kom deb li deb-microdrilling yog zoo heev nrog UAM. Silicon wafer drilling sai springs nco raws li ib qho piv txwv li ua lwm qhov chaw nrog qhov me me uas yuav tsim tam sim no nrog EDM los yog laser txiav yees. Ntau qhov chaw uas muaj qhov ntsug orientation machining mus kom ze uas kuj yuav tsum tau ib tug superb tiav kuj tseem txav mus rau ib lub ultrasonic-pab teb VMC. Pwm, piv txwv, yog ntxhib machined nyob rau hauv hom VMC hom thiab UAM hom tiav, polishes thiab deburrs nyob rau hauv ib lub teeb, txuag lub sij hawm thiab kev txhim kho geometrical. Nyob rau hauv ib rooj plaub uas muaj pwm txhuam hniav, tus qhua tuaj yeem siv sijhawm 40%. Dental pwm yog lwm daim ntawv thov rau lub cev xws li cov kws kho mob thiab cov khoom siv kho mob. Hauv kev lag luam tsheb, cov tuam txhab muaj kev paub txog cov txiaj ntsim ntawm kev siv UAM hauv cov txiaj ntsig deburring. Hauv aerospace, cov txheej txheem yog siv los tho compression cov leeg thiab muab cov titanium tuaj ua ib qho dej tiav. Cov neeg lag luam uas ua hauj lwm hauv cov tais diav thiab iav yog siv rau kev xyaum, txhuam thiab chamfer. Tongtai tau tshaj tawm hais tias nyob hauv kev txiav txim siab zoo tib yam ntawm kev ua haujlwm ntawm lub tuam txhab hauv Al6061 cov nram qab no tiav tau tiav:

Qee zaus cov lus nug txog qhov tshaj lij thiab cov ntsiab ntawm cov hlau EDMing tiv tiag UAMing. Thaum lub sij hawm pib khoom peev nyiaj rau UAM yog siab tshaj ib qho yooj yim EDM pob, lub ROI tuaj yeem cuam tshuam nrog UAM ntev li cov ntawv yuav haum. Kuj, muaj cov yeej ob tug cav tov nrog ib lub VMC / UAM configuration, muab cov neeg siv nrog ntau yam zoo heev. Yog hais tias qhov tsis tau teev tseg ntawm no yog zoo li cov haujlwm uas koj niaj zaus ua, ces nws tsim nyog rau koj lub sijhawm los tshawb UAM ntxiv.
