I-Edm isetshenziselwa ikakhulukazi ukwenza izibunjwa zemishini nezingxenye ezinobunjwa obuyinkimbinkimbi bemigodi nemigodi; Ukucubungula izinto ezihlukahlukene zokuqhuba, njenge-alloy eqinile nensimbi eqinile; Ukucubungula izimbobo ezijulile nezinhle, izimbobo ezimise okukhethekile, ama-grooves ajulile, amalunga amancane nokusika izingcezu ezincane, njll; Ukucupha amathuluzi okwakha ahlukahlukene, izifanekiso namageji endandatho yochungechunge, njll.

Umgomo wokucubungula

Ngesikhathi se-EDM, i-electrode yamathuluzi kanye ne-workpiece ixhunywe ngokulandelana kwezigxobo ezimbili zokunikezwa kwamandla kagesi futhi zicwiliswe oketshezini olusebenzayo, noma uketshezi olusebenzayo lukhokhiswa esikhaleni sokukhipha.I-electrode yamathuluzi ilawulwa ukuze iphakele i-workpiece ngokusebenzisa i-gap automatic control system. Lapho igebe phakathi kwama-electrode amabili lifinyelela ebangeni elithile, i-voltage ye-impulse esetshenziswa kuma-electrode amabili izokwephula uketshezi olusebenzayo futhi ikhiphe inhlansi.

Esiteshini esincane sokukhishwa, inani elikhulu lamandla okushisa ligxila khona manjalo, izinga lokushisa lingaba phezulu njenge-10000 ℃ futhi ingcindezi ibuye ibe noshintsho olubukhali, ukuze izinto zensimbi zokulandela umkhondo endaweni yokusebenza yaleli phuzu zincibilike ngokushesha futhi zihwamuke, futhi ziqhume zibe uketshezi olusebenzayo, zijike ngokushesha, zenze izinhlayiya zensimbi eqinile zisuswe ngesikhathi sokusebenza, bese zisuswa endaweni yokusebenza. amamaki emigodi emincane, ukuphuma kuyeka kafushane, uketshezi olusebenzayo phakathi kwama-electrode amabili ukubuyisela isimo sokuhlukanisa.

I-voltage ye-pulse elandelayo ibe ihlehla kwenye indawo lapho ama-electrode esondelene kakhulu komunye nomunye, akhiqize ukukhishwa kwenhlansi futhi aphinde inqubo.Ngakho, nakuba inani lensimbi eligqwalile ngokukhishwa kwe-pulse lincane kakhulu, insimbi eyengeziwe ingaguguleka ngenxa yezinkulungwane zokukhishwa kwe-pulse ngomzuzwana, ngokukhiqiza okuthile.

Ngaphansi kombandela wokugcina igebe lokukhipha njalo phakathi kwe-electrode yethuluzi kanye ne-workpiece, insimbi ye-workpiece igqwalile ngenkathi i-electrode yethuluzi iqhubeka ifakwa endaweni yokusebenza, futhi ekugcineni umumo ohambisana nokuma kwe-electrode yethuluzi umshini. izinto ezikwazi ukumelana nokugqwala ezine-conductivity enhle, indawo ephakeme yokuncibilika nokucutshungulwa kalula, njengethusi, i-graphite, i-copper-tungsten alloy ne-molybdenum.Enqubweni yomshini, i-electrode yethuluzi nayo inokulahlekelwa, kodwa ngaphansi kwenani lokugqwala kwensimbi yokusebenza, noma ngisho eduze nokulahlekelwa.

Njengomshini wokukhipha, uketshezi olusebenzayo luphinde lubambe iqhaza ekupholiseni nasekususweni kwe-chip ngesikhathi sokucubungula.Uketshezi olujwayelekile lokusebenza luphakathi ne-viscosity ephansi, indawo ephakeme ye-flash kanye nokusebenza okuzinzile, njenge-parafini, amanzi ahlanjululwe kanye ne-emulsion. I-electrode isondela, i-medium iphukile, bese kuphuma ukukhishwa kwenhlansi. Kanye nenqubo yokuwohloka, ukumelana phakathi kwama-electrode amabili kwehla kakhulu, futhi i-voltage phakathi kwama-electrode nayo iyancipha kakhulu.Isiteshi se-spark kufanele sicishwe ngesikhathi ngemuva kokugcinwa isikhathi esifushane (imvamisa i-10-7-10-3s) ukuze ulondoloze izici zokushisa "ukukhipha ukushisa" ukuguqulwa kwamandla akufinyeleli ekujuleni kwe-electrode ngesikhathi), ukuze amandla esiteshi asetshenziswe ebangeni elincane.Umphumela wamandla wesiteshi ungabangela i-electrode ukuba igqwale endaweni.Indlela eyenziwa yi-corrosion phenomenon ekhiqiza lapho kusetshenziswa ukukhishwa kwenhlansi yenza umshini wokulinganisa ubukhulu bezinto ibizwa ngokuthi i-electric spark spark ku-voltage ye-dispark machining a liquid dispark. Ngokohlobo lwe-electrode yethuluzi kanye nezici zokunyakaza okuhlobene phakathi kwe-electrode yethuluzi kanye nocezu lokusebenza, i-edM ingahlukaniswa ngezinhlobo ezinhlanu.Ukusikwa kwe-edM yocingo lwezinto eziphathwayo kusetshenziswa i-axially moving wire njenge-electrode yethuluzi kanye nocezu lokusebenza oluhamba ngendlela oyifunayo nosayizi; Ukugaya kwe-Edm kusetshenziswa ucingo noma ukwakha isondo lokugaya eliqhutshwayo njengethuluzi lokugaya i-electrode yokugaya i-keyhode; ipulaki yegeji [1], igiya njll.Ukucutshungulwa kwembobo encane, ingxubevange yendawo, ukuqinisa ingaphezulu kanye nezinye izinhlobo zokucubungula.I-Edm ingacubungula izinto zokwakha nobujamo obuyinkimbinkimbi okunzima ukusikwa ngezindlela ezijwayelekile zokucupha.Awekho amandla okusika ngesikhathi somshini;Ayikhiqizi i-burr ne-cutting groove nezinye iziphambeko;Impahla ye-electrode yethuluzi akudingeki ibe nzima kunomshini wokusebenza, ukucubungula amandla okuzenzakalelayo; indawo engaphezulu ikhiqiza ungqimba lwe-metamorphosis, okumele kwezinye izinhlelo zokusebenza luphinde lususwe;Kunzima ukubhekana nokungcola kwentuthu okubangelwa ukuhlanzwa nokucubungula uketshezi olusebenzayo.
