Edm feem ntau yog siv rau machining pwm thiab qhov chaw nrog cov duab ntawm qhov thiab kab noj hniav; Ua ntau yam khoom siv hluav taws xob, xws li tawv alloy thiab hardened steel; Ua qhov sib sib zog nqus thiab zoo, qhov tshwj xeeb zoo li lub qhov, qhov sib sib zog nqus grooves, nqaim pob qij txha thiab txiav nyias nyias, thiab lwm yam.; Machining ntau yam cuab yeej tsim, qauv thiab xov nplhaib ntsuas, thiab lwm yam.

Txoj cai ua

Thaum lub sij hawm EDM, cov cuab yeej electrode thiab cov khoom ua haujlwm tau txuas nrog rau ob tug ncej ntawm cov khoom siv hluav taws xob thiab muab tso rau hauv cov kua ua haujlwm, lossis cov kua ua haujlwm raug them rau hauv qhov sib txawv ntawm cov khoom siv hluav taws xob. Thaum qhov sib txawv ntawm ob lub electrodes mus txog ib qho kev ncua deb, qhov impulse voltage thov ntawm ob lub electrodes yuav ua rau cov kua ua haujlwm thiab ua kom muaj hluav taws xob tawm.

Nyob rau hauv lub micro channel ntawm paug, ib tug loj npaum li cas ntawm tshav kub lub zog yog concentrated instantaneously, qhov kub yuav siab li 10000 ℃ thiab lub siab kuj muaj ib tug ntse hloov, yog li ntawd lub zos cov ntaub ntawv hlau nyob rau ntawm qhov chaw ua hauj lwm ntawm qhov chaw no tam sim ntawd yaj thiab vaporize, thiab tawg mus rau hauv lub ua hauj lwm kua, sai condense, tsim cov khoom hlau hais, thiab muab tshem tawm los ntawm lub sij hawm ua hauj lwm qhov chaw ntawm lub qhov dej. cov qhab nia, qhov tso tawm tau nres luv luv, cov kua dej ua haujlwm ntawm ob lub electrodes los kho cov rwb thaiv tsev.

Tom ntej no mem tes voltage ces lov nyob rau lwm qhov chaw uas cov electrodes nyob ze rau ib leeg, ua ib tug spark paug thiab rov ua dua cov txheej txheem. Yog li, txawm hais tias tus nqi ntawm cov hlau corroded ib mem tes paug yog heev me me, ntau hlau yuav eroded vim ntau txhiab tus mem tes tawm ib ob, nrog ib tug tej yam productivity.

Raws li qhov xwm txheej ntawm kev ua kom tsis tu ncua ntawm qhov sib txawv ntawm lub cuab yeej electrode thiab lub tshuab ua haujlwm, cov hlau ntawm lub workpiece yog corroded thaum lub cuab yeej electrode txuas ntxiv mus rau hauv lub workpiece, thiab thaum kawg cov duab sib xws rau cov duab ntawm cov cuab yeej electrode yog machined. Yog li ntawd, ntev li ntev raws li cov duab ntawm cov cuab yeej electrode thiab cov txheeb ze cov lus tsa suab ntawm cov cuab yeej electrode yuav ua tau ntau yam. ntawm cov ntaub ntawv corrosion-resistant nrog zoo conductivity, siab melting point thiab yooj yim ua, xws li tooj liab, graphite, tooj liab-tungsten alloy thiab molybdenum.In the process of machining, the tool electrode kuj tau poob, tab sis tsawg dua tus nqi ntawm corrosion ntawm workpiece hlau, los yog txawm nyob ze rau tsis muaj kev poob.

Raws li qhov nruab nrab tawm, cov kua dej ua haujlwm kuj ua lub luag haujlwm hauv kev ua kom txias thiab nti tshem tawm thaum lub sijhawm ua haujlwm.Cov kua dej ua haujlwm feem ntau yog nruab nrab nrog qis viscosity, siab flash point thiab kev ua haujlwm ruaj khov, xws li kerosene, deionized dej thiab emulsion.Electric spark tshuab yog ib hom kev tawm ntawm tus kheej, nws cov yam ntxwv yog raws li nram no: ob lub electrodes ntawm qhov hluav taws xob tawm, qhov nruab nrab ntawm qhov hluav taws xob yog ua ntej. tawg, ces spark paug tshwm sim.Nrog rau cov txheej txheem tawg, qhov kev tiv thaiv ntawm ob electrodes txo sharply, thiab qhov voltage ntawm cov electrodes kuj txo sharply.Lub txim channel yuav tsum tau extinguished nyob rau hauv lub sij hawm tom qab tau khaws cia rau ib lub sij hawm luv luv (feem ntau 10-7-10-3s) kom tswj tau lub "txias ncej" cov yam ntxwv ntawm lub txim hluav taws xob hloov dua siab tshiab tsis ncav lub sij hawm (ie, lub zog hluav taws xob). tias lub zog channel yog siv rau qhov tsawg kawg nkaus.Cov nyhuv ntawm lub zog channel tuaj yeem ua rau cov electrode yuav tsum tau corroded hauv zos.Cov txheej txheem ntawm corrosion phenomenon uas tsim thaum siv spark paug undertakes dimensional machining rau cov khoom yog hu ua hluav taws xob spark machining.Edm yog ib tug spark paug nyob rau hauv ib tug kua nruab nrab nyob rau hauv ib tug tsawg voltage ntau yam. Hom.Wire-cut edM txiav cov khoom siv hluav taws xob siv axially txav hlau raws li cov cuab yeej electrode thiab workpiece txav raws li qhov xav tau cov duab thiab qhov loj me; Edm sib tsoo siv cov hlau los yog tsim cov hlau sib tsoo ua cov cuab yeej electrode rau keyhole los yog kev sib tsoo; Siv rau machining xov nplhaib gage, xov plug gage [1], iav thiab lwm yam. thiab cov duab nyuaj uas nyuaj rau kev txiav los ntawm cov txheej txheem machining zoo tib yam.Tsis muaj kev txiav quab yuam thaum lub sijhawm ua haujlwm; Tsis tsim cov burr thiab txiav zawj thiab lwm yam tsis xws luag; Cov cuab yeej electrode tsis tas yuav nyuaj dua li cov khoom siv ua haujlwm; Kev siv hluav taws xob ncaj qha ua haujlwm, yooj yim rau kev ua tiav automation; Tom qab ua tiav, qhov saum npoo tsim cov khoom siv hluav taws xob yuav tsum tsis txhob nyuaj dua li cov khoom siv ua haujlwm; ncaj qha siv hluav taws xob ua, yooj yim kom ua tiav automation; Tom qab ua tiav, qhov saum npoo yuav ua rau cov khoom siv hluav taws xob tsis zoo yuav tsum tau ua kom muaj teeb meem ntxiv rau hauv cov ntawv pov thawj. los ntawm kev ua kom huv thiab ua cov kua dej ua haujlwm.
