Thaum EDM, lub cuab yeej electrode thiab lub workpiece yog feem sib txuas nrog ob tus ncej ntawm lub zog hluav taws xob thiab muab tso rau hauv cov kua ua haujlwm, lossis cov kua ua haujlwm tau raug them rau cov paug tawm.Qhov cuab yeej electrode yog tswj kom pub lub workpiece los ntawm kis tsis siv neeg tswj system. Thaum qhov sib txawv nruab nrab ntawm ob lub tshuab hluav taws xob tau mus txog qee qhov deb, lub zog hluav taws xob thov ntawm ob lub electrodes yuav zom cov kua ua hauj lwm thiab tsim kom muaj lub txim hluav taws xob.

Hauv micro channel ntawm kev tso tawm, ntau qhov ntawm lub zog kub yog ua kom pom tseeb tam sim ntawd, qhov ntsuas kub tuaj yeem siab txog 10000 ℃ thiab lub siab tseem muaj qhov hloov siab, kom lub hauv paus taug hauv cov hlau cov khoom ntawm qhov chaw ua haujlwm ntawm qhov taw tes tam sim no yaj thiab vaporize, thiab tawg rau hauv cov kua ua hauj lwm, sai sai condense, tsim cov nplais cov hlau tsis zoo, thiab raug tshem tawm los ntawm cov kua ua haujlwm.Thaum lub sijhawm no nyob rau saum npoo ntawm lub workpiece yuav tawm ib lub qhov me me, qhov paug tawm luv luv, ua haujlwm kua dej ntawm ob lub electrodes los kho lub xeev rwb thaiv tsev.

Tom ntej no lub plawv hluav taws xob voltage ces tawg rau lwm qhov chaw uas cov xaim hluav taws xob sib raug zoo nyob ze rau lwm tus, ua kom muaj lub txim hluav taws xob thiab rov ua cov txheej txheem.Yog li, txawm hais tias cov hlau xeb rau ib lub zog tawm tsawg heev, ntau hlau tuaj yeem yaig vim rau txhiab phav phav tawm hluav taws xob toj ib ob, nrog qee yam khoom tsim tau.

Nyob rau hauv cov xwm txheej ntawm kev ua kom tsis tu ncua qhov sib txawv nruab nrab ntawm lub cuab yeej electrode thiab lub workpiece, hlau ntawm lub workpiece yog corroded thaum lub cuab yeej electrode tsis tu ncua mus rau hauv qhov chaw ua haujlwm, thiab thaum kawg cov duab sib nug xov mus rau qhov zoo ntawm lub cuab yeej electrode yog machined. Yog li no, ntev npaum li cov duab ntawm cov cuab yeej electrode thiab qhov txheeb ze hom kev hloov nruab nrab ntawm cov cuab yeej electrode thiab qhov chaw ua haujlwm, ntau cov ntaub ntawv yooj yim tuaj yeem ua machined.Tool electrodes feem ntau yog ua los ntawm corrosion-resistant cov ntaub ntawv nrog zoo conductivity, high melting point thiab kev ua haujlwm yooj yim, xws li tooj liab, graphite, tooj liab-tungsten alloy thiab molybdenum.Hauv cov txheej txheem ntawm kev siv lub tshuab, lub cuab yeej electrode kuj muaj qhov poob, tab sis tsawg dua qhov tsis muaj xeb ntawm cov haujlwm workpiece hlau, lossis txawm tias ze rau tsis muaj qhov poob.

Raws li qhov nruab nrab tso tawm, cov kua dej ua haujlwm tseem ua lub luag haujlwm txias thiab nti tawm lub sijhawm ua haujlwm.Hauv cov kua dej ua haujlwm yog nruab nrab nrog qis viscosity, lub teeb nyem siab thiab kev ua haujlwm ruaj khov, xws li roj av, dej deionized thiab emulsion.Electric lub tshuab hluav taws xob yog ib hom kev rov tawm tus kheej, nws cov yam ntxwv yog li hauv qab no: ob lub tshuab hluav taws xob ntawm cov hluav taws xob tawm ntawm hluav taws xob muaj qhov ntsuas hluav taws xob ua ntej tso tawm, thaum ob lub tshuab hluav taws xob mus txog, qhov nruab nrab tau tawg, tom qab ntawd cov txim taws tshwm sim.Muaj nrog cov txheej txheem tawg, qhov kev cuam tshuam ntawm ob lub electrodes txo qis zuj zus, thiab qhov hluav taws xob ntawm qhov hluav taws xob kuj txo qis heev.Qhov channel hluav taws xob yuav tsum tau muab tua kom txog lub sijhawm tom qab tau tswj lub sijhawm luv luv (feem ntau 10-7-10-3s) los tswj lub " txias ncej ”cov yam ntxwv ntawm lub txim hluav taws xob (piv txwv li, lub zog cua kub ntawm cov channel hloov hluav taws xob tsis ncav lub qhov tob ntawm cov electrode hauv lub sijhawm), yog li cov channel zog siv rau qhov tsawg kawg nkaus.Qhov nyhuv ntawm channel zog tuaj yeem ua rau cov electrode yuav xeb hauv zos.Qhov txheej txheem uas qhov teeb meem corrosion uas tsim thaum siv cov txim hluav taws xob ua kom pom qhov sib txawv qhov machining rau cov khoom siv yog hu ua hluav taws xob machining.Edm yog lub txim hluav taws xob hauv cov kua nruab nrab hauv qhov hluav taws xob tsawg dua.Qhov tsim rau daim qauv ntawm cov cuab yeej electrode thiab cov yam ntxwv ntawm kev sib hloov ntawm cov cuab yeej hluav taws xob thiab cov khoom ua haujlwm, edM tuaj yeem muab faib ua tsib yam.Wire-txiav edM txiav ntawm cov khoom siv hluav taws xob siv cov axially tsiv hlau raws li cov cuab yeej electrode thiab workpiece txav raws li qhov xav tau thiab qhov loj me; Edm sib tsoo siv cov hlau los tsim kev sib tsoo lub log raws li cov cuab yeej hluav taws xob rau lub qhov tseem ceeb lossis kev sib tsoo; Siv rau machining xov nplhaib gage, xov ntsaws gage [1], iav thiab lwm yam. , nto qhov muaj zog thiab lwm hom kev ua tiav.Edm tuaj yeem ua cov ntaub ntawv thiab cov duab ntxig uas nyuaj rau kev txiav los ntawm kev siv lub tshuab ua dog dig cov tswv yim.Tsis txiav quab yuam thaum lub sijhawm machining; Tsis tsim burr thiab txiav zawj thiab lwm yam tsis xws luag; Cov khoom siv hluav taws xob cov khoom siv tsis tas yuav nyuaj dua cov khoom siv ua haujlwm; Kev siv hluav taws xob ncaj qha kev siv hluav taws xob, yooj yim kom ua tiav automation; Tom qab ua tiav, nto tsim ib txheej metamorphosis, uas nyob rau hauv qee qhov kev siv yuav tsum raug tshem tawm ntxiv; Nws muaj teeb meem los cuam tshuam nrog cov pa luam yeeb ua pa los ntawm kev ua kom huv thiab ua haujlwm ntawm cov kua dej.
