Hluav taws xob paug machining(EDM) yog tus txheej txheem tshwj xeeb machining uas ua rau kev siv hluav taws xob etching nyhuv ua los ntawm cov mem tes tawm ntawm cov hluav taws xob nqus ntawm cov kua ua haujlwm kom tshem tawm cov ntaub ntawv pov thawj. Tam sim no, EDM thev naus laus zis tau siv dav hauv kev ua cov khoom siv ntau nrog cov ntsiab lus siab, siab lub zog thiab siab tawv, xws li cov tawv tawv tawv, steel hlau, tuag steel, cemented carbide, thiab lwm yam. nto thiab tshwj xeeb uas yuav tsum tau.
Lub hauv paus ntsiab lus ntawm hluav taws xob tawm machining yog lub workpiece thiab cov cuab yeej hluav taws xob feem txuas nrog lub zog ntawm lub plawv pulse ntawm ob qhov sib txawv electrode polarity, raws li cov cuab yeej thiab cov workpiece (qhov zoo thiab tsis zoo electrodes) ntawm cov mem tes hluav taws xob tawm ntawm hluav taws xob mus rau kev tshem tawm nyob rau hauv ntau dhau ntawm kev xeb hlau. , txhawm rau kom ua tiav qhov workpiece loj, cov duab thiab saum npoo zoo ntawm kev tsim ua ntej yuav tsum tau ua.
Hauv EDM, cov cuab yeej hluav taws xob feem ntau siv nrog cov hluav taws xob zoo, cov ntsiab lus melting thiab yooj yim rau kev ua, xws li tooj liab, graphite, tooj-tungsten alloy thiab molybdenum, thiab lwm yam. Cov kua dej ua haujlwm feem ntau yog siv hauv nruab nrab nrog qis viscosity, lub teeb nyem siab thiab kev ua haujlwm ruaj khov, xws li cov kerosene, dej deionized thiab emulsion. Tsis tas li ntawd, raws li qhov tawm hauv nruab nrab, cov kua ua haujlwm tseem ua lub luag haujlwm ntawm cov txheej txheem txias, nti tshem tawm thiab lwm yam.
