EDMni uburyo bwo gutunganya bukoresha cyane cyane electrode isohora (EDM electrode) hamwe na geometrie yihariye yo gutwika geometrie ya electrode mugice cyicyuma (kiyobora).Inzira ya EDMisanzwe ikoreshwa mugukora ubusa no guta bipfa.
Uburyo bwo gutunganya ibipimo bifatika ukoresheje ibintu byangirika biterwa no gusohora ibintu byitwa EDM.EDM nigisohoka gisohora mumazi mumazi ya voltage yo hasi.
EDM ni ubwoko bwo kwishima wenyine, kandi ibiyiranga ni ibi bikurikira: electrode ebyiri zo gusohora ikirere zifite voltage nyinshi mbere yo gusohoka.Iyo electrode zombi zegeranye, nyuma yuburyo hagati yazo zimenetse, isohoka ryimyuka ihita.Hamwe no gusenyuka, guhangana hagati ya electrode zombi bigabanuka cyane, kandi n’umuvuduko uri hagati ya electrode zombi nazo zigabanuka cyane.Umuyoboro wa spark ugomba kuzimya mugihe nyuma yo gukomeza igihe gito (mubisanzwe 10-7-10-3s), kugirango ugumane "pole ikonje" ibiranga imyuka isohoka (ni ukuvuga ingufu zubushyuhe bwumuyoboro uhindura ingufu ntishobora kwanduzwa mubwimbike bwa electrode), kugirango ingufu za Umuyoboro zikore ku gipimo gito cyane.Ingaruka zingufu zumuyoboro zirashobora gutuma electrode yangirika igice.
Ibiranga:
1.EDM ni iyimashini idahuye
Ntaho uhurira hagati yigikoresho cya electrode nigikorwa, ariko hariho icyuho cyo gusohora.Iki cyuho muri rusange kiri hagati ya 0.05 ~ 0.3mm, kandi rimwe na rimwe gishobora kugera kuri 0.5mm cyangwa kinini.Icyuho cyuzuyemo amazi akora, hamwe numuvuduko mwinshi wo gusohora Pulse, gusohora ruswa kumurimo.
2.Ushobora "gutsinda ubukana n'ubwitonzi"
Kubera ko EDM ikoresha mu buryo butaziguye ingufu z'amashanyarazi n'imbaraga z'ubushyuhe kugirango ikureho ibyuma, ntaho bihuriye n'imbaraga n'ubukomezi bw'ibikoresho byo mu kazi, bityo ibikoresho bya electrode byoroshye birashobora gukoreshwa mugutunganya ibihangano bigoye kugirango ugere "ubworoherane butsinda gukomera".
3.Ushobora gutunganya ibikoresho byose bigoye-kumashini ibyuma nibikoresho byayobora
Kubera ko kuvanaho ibikoresho mugihe cyo gutunganya bigerwaho ningaruka zamashanyarazi nubushyuhe bwo gusohora, imashini yibikoresho ahanini biterwa nubushyuhe bwamashanyarazi hamwe nubushyuhe bwibikoresho, nkibishonga, aho bitetse, ubushobozi bwubushyuhe bwihariye, ubushyuhe bwumuriro, ubukana , nibindi, mugihe hafi Ntaho bihuriye nimiterere yubukanishi (gukomera, imbaraga, nibindi).Muri ubu buryo, irashobora guca ku mbibi z’ibikoresho gakondo byo gukata ku bikoresho, kandi irashobora kumenya gutunganya ibihangano bikomeye kandi bikomeye hamwe nibikoresho byoroshye, ndetse nibikoresho bya superhard nka polycrystalline diamant umurongo na nitride ya cubic boron irashobora gutunganywa.
4.Ubuso bugoye burashobora gukorwa
Kubera ko imiterere yigikoresho electrode ishobora gukopororwa gusa kurupapuro rwakazi, birakwiriye cyane cyane gutunganya ibihangano bifite imiterere igoye, nko gutunganya ibintu byoroshye.By'umwihariko, gukoresha tekinoroji yo kugenzura imibare bituma iba impamo gukoresha electrode yoroshye mugutunganya ibice bifite imiterere igoye.
5.Ibice bifite ibisabwa byihariye birashobora gutunganywa
Irashobora gutunganya ibice hamwe nibisabwa byihariye nkurukuta ruto, rukomeye, rukomeye, umwobo muto, umwobo udasanzwe, umwobo wimbitse, nibindi, kandi birashobora no gutunganya inyuguti nto kumurongo.Kubera ko igikoresho cya electrode hamwe nakazi kidahuza muburyo butaziguye mugihe cyo gutunganya, nta mbaraga zo gukata zogukora, bityo rero birakwiriye gutunganya ibihangano bidafite ubukana buke na micromachining.
EDM ni ubwoko bumwe bwo gutunganya, turashobora kugufasha gukemura ikibazo cyawe bwite.
Niba ufite ikibazo cyangwa ushaka gukenera serivisi iyo ari yo yose yerekeye imashini ya CNC, nyamuneka twandikire kubuntu.
