Yuav ua li cas yog hluav taws xob tawm machining?

Electric discharge machining yog ib qho tshwj xeeb machining tshuab uas tuaj yeem tshem tawm cov ntaub ntawv los ntawm cov nyhuv ablation ntawm cov hluav taws xob thaum lawv tawm ntawm electrodes. Vim tias txoj kev ua haujlwm no tsim nyog rau cov ntaub ntawv nyuaj uas nyuaj rau kev txiav, nws yog dav siv hauv aviation, aerospace, machinery thiab lwm yam. Qhov tseeb ntawm hluav taws xob tawm machining yog ib qho ntawm cov cim tseem ceeb ntawm txoj kev ua no. Yog li, yuav ua li cas yog hluav taws xob tawm machining?

Hluav taws xob tawm machining yog tsim rau kev ua haujlwm zoo thiab meej ntawm ntau cov ntaub ntawv nyuaj uas nyuaj rau kev txiav. Nws muaj ntau yam kev siv, suav nrog aerospace, tsheb, tshuab cuab yeej, hluav taws xob thiab lwm yam.

Precision ntawm hluav taws xob tawm machining
Qhov tseeb ntawm hluav taws xob tawm machining yog hais txog qhov sib txawv ntawm qhov loj ntawm lub tshuab ua haujlwm thiab qhov xav tau loj. Qhov siab dua qhov tseeb, qhov siab dua qhov zoo ntawm cov khoom. Txawm li cas los xij, qhov tseeb ntawm cov khoom siv hluav taws xob tawm yog cuam tshuam los ntawm ntau yam, xws li cov khoom siv hluav taws xob, cov dej ua haujlwm, cov khoom siv hluav taws xob, cov yam ntxwv sib txawv, kev ua haujlwm tam sim no, mem tes dav, thiab lwm yam. Cov yam ntxwv no yuav cuam tshuam cov nyhuv thiab qhov tseeb ntawm hluav taws xob tawm machining. .

Yam cuam tshuam rau qhov raug ntawm hluav taws xob tawm machining
Nyob rau hauv hluav taws xob paug machining, thaum lub txim hluav taws xob tawm ntawm electrodes, high-temperature molten droplets yog generated. Cov molten droplets dhau los ntawm qhov sib txawv ntawm cov electrodes thiab ua rau muaj zog thermal corrosion ntawm electrode nto. Hauv cov txheej txheem no, qhov loj me thiab qhov ceev ntawm cov molten droplets yuav cuam tshuam rau kev ua haujlwm raug. Yog hais tias qhov me me ntawm cov tee dej loj dhau lawm, cov txheej txheem ua tiav yuav ntxhib; yog tias qhov ceev ntawm cov tee dej yog siab dhau lawm, cov txheej txheem ua tiav yuav me dua. Tsis tas li ntawd, cov duab thiab qhov loj ntawm cov electrode tseem yuav cuam tshuam rau kev ua haujlwm raug. Yog tias cov duab thiab qhov loj ntawm cov electrode tsis sib xws rau qhov yuav tsum tau ua, nws tseem yuav ua rau muaj kev sib txawv hauv kev ua haujlwm raug.

Txhim kho qhov raug ntawm hluav taws xob tawm machining
Txhawm rau txhim kho qhov tseeb ntawm kev siv hluav taws xob tawm tshuab, tib neeg tau tsim ntau yam kev ua haujlwm tshiab thiab khoom siv. Piv txwv li, CNC hluav taws xob tawm machining, micro hluav taws xob tawm machining, ultrasonic hluav taws xob tawm machining, thiab lwm yam. Cov thev naus laus zis tshiab no tuaj yeem tsis tsuas yog txhim kho kev ua haujlwm zoo, tab sis kuj tsim cov khoom zoo thiab ntau qhov chaw. Tam sim no, qhov tseeb ntawm hluav taws xob tawm tshuab tuaj yeem ncav cuag micron lossis txawm tias qib nanometer. Piv txwv li, qee cov khoom siv hluav taws xob ua haujlwm siab heev tuaj yeem tswj cov kev txav ntawm cov electrodes nrog micron-theem raug rau kev ua haujlwm siab. Tsis tas li ntawd, qee cov kua dej ua haujlwm tshiab thiab cov khoom siv hluav taws xob mem tes tuaj yeem txhim kho qhov tseeb ntawm cov khoom siv hluav taws xob tawm. Piv txwv li, qee cov kua ua haujlwm tshiab tuaj yeem txo qhov me me ntawm cov tee dej, yog li txhim kho qhov zoo tom qab ua tiav; qee cov khoom siv hluav taws xob tshiab muaj peev xwm tswj tau lub zog thiab ceev ntawm cov pa tawm, yog li tswj cov particle loj thiab ceev ntawm cov tee dej, thiab txhim kho kev ua haujlwm raug.

Cov ntsiab lus
Nyob rau hauv luv luv, qhov tseeb ntawm hluav taws xob paug machining yog cuam tshuam los ntawm ntau yam, xws li cov khoom siv electrode, ua hauj lwm kua hom, mem tes fais fab mov, cov yam ntxwv sib txawv, machining tam sim no, mem tes dav, thiab lwm yam. yam tseem ceeb yuav tsum tau txiav txim siab zoo thiab cov txheej txheem tshiab thiab cov cuab yeej siv. Tam sim no, qhov tseeb ntawm kev siv hluav taws xob tawm tshuab tuaj yeem ncav cuag micron lossis txawm tias qib nanometer, uas tuaj yeem ua tau raws li kev ua haujlwm siab.
