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 kumaliseche gap.The elekitirodi chida umalamuliridwa kudyetsa workpiece mwa kusiyana dongosolo basi kulamulira. 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 yaying'ono njira kumaliseche, kuchuluka kwa kutentha mphamvu anaikira yomweyo, kutentha akhoza kukhala mkulu monga 10000 ℃ ndi kuthamanga alinso kusintha lakuthwa, kuti m'deralo kufufuza zipangizo zitsulo pa ntchito pamwamba pa mfundo imeneyi yomweyo kusungunuka ndi nthunzi, ndi kuphulika mu madzi ntchito, mwamsanga condense, kupanga zitsulo olimba particles kutali ndi nthawi yamadzimadzi achotsedwa ntchito pamwamba pa ntchito. ting'onoting'ono dzenje zizindikiro, kumaliseche anasiya mwachidule, madzimadzi ntchito pakati maelekitirodi awiri kubwezeretsa boma kutchinjiriza.

Chotsatira cha pulse voteji chimasweka pamalo ena pomwe ma elekitirodi amakhala pafupi ndi mzake, kutulutsa kutuluka kwa spark ndikubwereza ndondomekoyi.Choncho, ngakhale kuti kuchuluka kwa zitsulo zowonongeka pamtundu uliwonse wa kutulutsa kumakhala kochepa kwambiri, zitsulo zambiri zimatha kuwonongeka chifukwa cha zikwi zambiri za kutulutsa mpweya pamphindi, ndi zokolola zina.

Pansi pa kusunga kusiyana kosalekeza pakati pa electrode chida ndi workpiece, chitsulo cha workpiece ndi dzimbiri pamene elekitirodi chida mosalekeza kudyetsedwa mu workpiece, ndipo potsiriza mawonekedwe lolingana ndi mawonekedwe a electrode chida ndi machined.Chifukwa chake, malingana ngati mawonekedwe a electrode chida ndi wachibale zoyenda mode pakati pa electrode chida ndi maelekitirodi osiyanasiyana makina opangira maelekitirodi akhoza kukhala opangidwa ndi maelekitirodi ovuta, maelekitirodi opangidwa ndi makina opangidwa ndi makina opangira makina. zipangizo zosagwira dzimbiri zokhala ndi madulidwe abwino, malo osungunuka kwambiri komanso kukonza kosavuta, monga mkuwa, graphite, aloyi yamkuwa-tungsten ndi molybdenum. Pamakina, chida cha elekitirodi chimakhalanso ndi kutayika, koma osachepera kuchuluka kwa dzimbiri la chitsulo chogwirira ntchito, kapena ngakhale kuyandikira kutayika konse.

Monga kutayira sing'anga, madzimadzi ntchito amathandizanso kuzirala ndi Chip kuchotsa pa processing.Wamba ntchito madzimadzi ndi sing'anga ndi otsika mamasukidwe akayendedwe, mkulu kung'anima mfundo ndi ntchito khola, monga palafini, madzi deionized ndi emulsion.Electric spark makina ndi mtundu wa kudzikonda osangalala kumaliseche, makhalidwe ake ndi motere: ndi kutulutsa voteji awiri pamaso pa ma electrodes awiri kutulutsa, ma electrodes awiri asanayambe kutuluka. Njira ya electrode, sing'anga imasweka, ndiye kutulutsa kwamoto kumachitika. Pamodzi ndi njira yowonongeka, kukana pakati pa ma electrode awiri kumachepa kwambiri, ndipo mphamvu yamagetsi pakati pa ma electrode imachepa kwambiri. kutembenuka mphamvu sikufika kuya kwa elekitirodi mu nthawi), kotero kuti mphamvu njira ntchito kwa osachepera range.The mphamvu njira kungachititse kuti elekitirodi kuti dzimbiri locally.Njira kuti dzimbiri chodabwitsa kuti umatulutsa pamene ntchito spark discharge imapanga machining dimensional kwa zinthu amatchedwa magetsi spark sing'anga mu machining amadzimadzi a m'munsi ndi dispark machining Edmcha. Malinga ndi mawonekedwe a chida elekitirodi ndi makhalidwe a kayendedwe wachibale pakati pa 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 kugaya gudumu monga chida electrode kupanga grinding keyhode; pulagi gage [1], zida etc.Small dzenje processing, aloyi pamwamba, kulimbikitsa pamwamba ndi mitundu ina processing.Edm akhoza pokonza zipangizo ndi akalumikidzidwa zovuta kuti adulidwe ndi wamba machining method.No kudula mphamvu pa Machining;Si kutulutsa burr ndi kudula poyambira ndi zolakwika zina;Chida electrode chuma chakuthupi sayenera kukhala ovuta kuposa processing mphamvu, Direct ntchito makina opangira; pamwamba umapanga wosanjikiza metamorphosis, amene ntchito zina ayenera kuchotsedwa; Zimakhala zovuta kuthana ndi utsi kuipitsa chifukwa kuyeretsedwa ndi processing madzimadzi ntchito.
