Pa EDM, chida elekitirodi ndi workpiece ndi ankalemekeza olumikizidwa kwa mizati awiri a zimachitika mphamvu kotunga ndi kumizidwa mu madzi ntchito, kapena madzi ntchito mlandu mu kukhetsa gap. The elekitirodi chida umalamuliridwa kudyetsa workpiece kudzera. gap automatic control system. Pamene kusiyana pakati pa maelekitirodi awiriwo kufika pa mtunda wina, mphamvu yamagetsi yomwe imagwiritsidwa ntchito pa maelekitirodi awiriwa idzaphwanya madzi omwe akugwira ntchito ndikutulutsa spark discharge.
Mu njira yaying'ono yotulutsira, mphamvu zambiri zotentha zimakhazikika nthawi yomweyo, kutentha kumatha kufika 10000 ℃ ndipo kupanikizika kumakhala ndi kusintha kwakukulu, kotero kuti zida zachitsulo zotsatizana zimagwira ntchito pamalopo nthawi yomweyo. Sungunulani ndi nthunzi, ndi kuphulika mu madzi ntchito, mwamsanga condense, kupanga olimba zitsulo particles, ndi kuchotsedwa ntchito madzi ntchito. ntchito madzimadzi pakati maelekitirodi awiri kubwezeretsa boma kutchinjiriza.
Chotsatira cha pulse voteji chimasweka pamalo ena pomwe ma elekitirodi amakhala pafupi ndi mnzake, kutulutsa kutulutsa kwamoto ndikubwereza ndondomekoyi.Chotero, ngakhale kuchuluka kwa zitsulo zomwe zawonongeka pa kutulutsa kwamphamvu ndizochepa kwambiri, chitsulo chochulukirapo chikhoza kusokonekera chifukwa. zikwizikwi za kugunda kwa mtima pa sekondi imodzi, ndi zokolola zina.
Pansi pa kusunga kusiyana kosalekeza pakati pa electrode chida ndi workpiece, chitsulo cha workpiece ndi dzimbiri pamene electrode chida mosalekeza kudyetsedwa workpiece, ndipo potsiriza mawonekedwe lolingana ndi mawonekedwe a electrode chida ndi machined. Choncho, malinga ngati mawonekedwe a electrode chida ndi wachibale zoyenda mode pakati chida elekitirodi ndi workpiece, zosiyanasiyana mbiri zovuta akhoza machined.Maelekitirodi chida nthawi zambiri opangidwa ndi dzimbiri zosagwira zipangizo ndi conductivity wabwino, mkulu kusungunuka mfundo. ndi kukonza kosavuta, monga mkuwa, graphite, copper-tungsten alloy ndi molybdenum.Mu ndondomeko ya machining, electrode chida chimakhalanso ndi kutayika, koma osachepera kuchuluka kwa dzimbiri zitsulo workpiece zitsulo, kapena ngakhale pafupi palibe imfa.
Monga sing'anga yotulutsa, madzimadzi ogwirira ntchito amathandizanso kuziziritsa ndi kuchotsa chip panthawi ya processing.Madzimadzi ogwira ntchito apakati ndi otsika kukhuthala, kung'anima kwapamwamba komanso magwiridwe antchito okhazikika, monga palafini, madzi oyeretsedwa ndi emulsion.Makina a spark amagetsi ndi mtundu wodzisangalatsa wokha, mawonekedwe ake ndi awa: ma elekitirodi awiri a spark discharge amakhala ndi voteji yayikulu isanatuluke, ma elekitirodi awiri akayandikira, sing'angayo imasweka, ndiye kutulutsa kwamoto kumachitika. kukana pakati pa maelekitirodi awiriwa kumachepa kwambiri, ndipo mphamvu yamagetsi pakati pa ma electrode imachepanso kwambiri.Njira yamoto iyenera kuzimitsidwa pakapita nthawi itatha kusungidwa kwa nthawi yochepa (nthawi zambiri 10-7-10-3s) kusunga " Mzati Wozizira "makhalidwe a spark discharge (ie, mphamvu ya kutentha ya kutembenuka kwa tchanelo sikufika pakuya kwa elekitirodi mu nthawi), kotero kuti mphamvu ya njirayo ikugwiritsidwa ntchito pamlingo wocheperako. The electrode kuti dzimbiri m'deralo.Njira kuti dzimbiri chodabwitsa kuti zimagwiritsa ntchito spark discharge imapanga dimensional Machining kwa zinthu amatchedwa electric spark Machining. cha elekitirodi chida ndi makhalidwe a kayendedwe wachibale pakati chida elekitirodi ndi workpiece, edM akhoza kugawidwa mu mitundu isanu.Waya-odulidwa edM kudula zipangizo conductive ntchito axially kusuntha waya monga chida elekitirodi ndi workpiece kusuntha pamodzi mawonekedwe ankafuna ndi kukula;Edm akupera ntchito waya kapena kupanga conductive mphero gudumu ngati chida elekitirodi kwa keyhole kapena kupanga akupera; Ntchito Machining mphete gage, ulusi pulagi gage [1], zida etc.Small dzenje processing, pamwamba alloying, pamwamba kulimbikitsa ndi mitundu ina processing.Edm akhoza zida zopangira ndi mawonekedwe ovuta omwe ndi ovuta kudulidwa ndi njira wamba machining.Palibe mphamvu yodulira panthawi yopangira; Satulutsa burr ndi kudula poyambira ndi zolakwika zina; Zida zama elekitirodi siziyenera kukhala zolimba kuposa zida zogwirira ntchito; Kugwiritsa ntchito magetsi mwachindunji kukonza mphamvu, zosavuta kukwaniritsa zokha; Pambuyo pokonza, pamwamba pamapanga chosanjikiza cha metamorphosis, chomwe muzinthu zina chiyenera kuchotsedwa; Ndizovuta kuthana ndi kuipitsidwa kwa utsi chifukwa cha kuyeretsedwa ndi kukonza madzimadzi ogwira ntchito.
