I-EDM-Olunye uhlobo lwe-Machining Process

I-EDMinqubo yokwenza imishini esebenzisa ngokuyinhloko i-electrode yokukhipha (i-EDM electrode) enejiyomethri ethile ukushisa i-geometry ye-electrode engxenyeni yensimbi (conductive).Inqubo ye-EDMngokuvamile isetshenziswa ekukhiqizeni okungenalutho kanye nokufaka ukufa.
Indlela yokucutshungulwa kobukhulu bezinto kusetshenziswa isenzakalo sokugqwala esikhiqizwa ukukhishwa kwenhlansi ibizwa ngokuthi i-EDM.I-EDM iwukukhishwa kwenhlansi endaweni ewuketshezi ebangeni eliphansi lamandla kagesi.
I-EDM iwuhlobo lokukhishwa okuzithokozisayo, futhi izici zayo zimi kanje: Ama-electrode amabili okukhishwa kwe-spark ane-voltage ephezulu ngaphambi kokukhishwa.Lapho ama-electrode amabili esondelene, ngemva kokuba i-medium phakathi kwawo iphukile, ukukhishwa kwe-spark kwenzeka ngokushesha.Ngenqubo yokuwohloka, ukumelana phakathi kwama-electrode amabili kuncipha kakhulu, futhi i-voltage phakathi kwama-electrode amabili nawo ayancipha kakhulu.Isiteshi senhlansi kufanele sicishwe ngesikhathi ngemuva kokugcina isikhathi esifushane (imvamisa i-10-7-10-3s), ukuze kugcinwe izici "ezibandayo" zokukhishwa kwenhlansi (okungukuthi, amandla okushisa okuguqulwa kwamandla wesiteshi. ayikwazi ukudluliselwa ekujuleni kwe-electrode), ukuze amandla e-Channel enze ngesilinganiso esincane kakhulu.Umthelela wamandla wesiteshi ungabangela ukuthi i-electrode igqwale kancane.

Izici:
I-1.EDM ingeyomshini ongeyena othintana naye
Akukho ukuxhumana okuqondile phakathi kwe-electrode yethuluzi kanye ne-workpiece, kodwa kunegebe lokukhishwa kwenhlansi.Leli gebe ngokuvamile liphakathi kuka-0.05~0.3mm, futhi ngezinye izikhathi lingase lifinyelele ku-0.5mm noma ngisho nangaphezulu.Igebe ligcwele uketshezi olusebenzayo, futhi ukukhishwa kwe-Pulse kwengcindezi ephezulu, ukugqwala kokukhipha endaweni yokusebenza.

2.Ingakwazi “ukunqoba ukuqina ngobumnene”
Njengoba i-EDM isebenzisa ngokuqondile amandla kagesi namandla ashisayo ukuze isuse izinto zensimbi, ayihlangene kancane namandla nobulukhuni bezinto zokusebenza, ngakho-ke ama-electrode amathuluzi athambile angasetshenziswa ukucubungula ama-workpieces aqinile ukuze kuzuzwe "ubumnene bunqoba ukuqina".

I-3.Ingakwazi ukucubungula noma yiziphi izinto zensimbi ezinzima emshinini nezinto zokuqhuba
Njengoba ukususwa kwezinto ngesikhathi sokucubungula kufinyelelwa yimiphumela kagesi neyokushisa yokukhishwa, ukuqhutshwa kwezinto ngokuyinhloko kuncike ekuziphatheni kukagesi kanye nezakhiwo ezishisayo zezinto zokwakha, njengendawo yokuncibilika, indawo yokubilisa, umthamo wokushisa othize, ukuqhutshwa kwe-thermal, resistivity. , njll., kuyilapho cishe Ayihlangene nezakhiwo zayo zemishini (ukuqina, amandla, njll.).Ngale ndlela, ingakwazi ukunqamula imikhawulo yamathuluzi okusika endabuko kumathuluzi, futhi ingakwazi ukubona ukucutshungulwa kwezinto zokusebenza eziqinile neziqinile ngamathuluzi athambile, ngisho nezinto eziqinile kakhulu njengemigqa yedayimane ye-polycrystalline kanye ne-cubic boron nitride ingacutshungulwa.

I-4.Izindawo ezinokwakheka okuyinkimbinkimbi zingenziwa ngomshini
Njengoba ukwakheka kwe-electrode yethuluzi kungakopishwa kalula ku-workpiece, ifaneleka ngokukhethekile ukucutshungulwa kwezinto zokusebenza ezinobunjwa obuyinkimbinkimbi, njengokucubungula isikhunta se-cavity.Ikakhulukazi, ukwamukelwa kobuchwepheshe bokulawula izinombolo kwenza kube ngokoqobo ukusebenzisa ama-electrode alula ukucubungula izingxenye ezinezimo eziyinkimbinkimbi.

I-5.Izingxenye ezinezidingo ezikhethekile zingacutshungulwa
Ingakwazi ukucubungula izingxenye ezinezidingo ezikhethekile ezifana nezindonga ezincane, ukunwebeka, ukuqina okuphansi, izimbobo ezincane, izimbobo ezimise okukhethekile, izimbobo ezijulile, njll., futhi ingacubungula izinhlamvu ezincane esikhunjini.Njengoba i-electrode yethuluzi kanye ne-workpiece ingathintani ngokuqondile ngesikhathi somshini, awekho amandla okusika omshini, ngakho-ke kufanelekile umshini wokusebenza obunzima obuphansi kanye ne-micromachining.

I-EDM iwuhlobo olulodwa lwenqubo yokwenza imishini, singakusiza ukuxazulula inkinga yakho yangokwezifiso.

Uma unemibuzo noma ufuna ukudinga noma iyiphi insizakalo mayelana ne-CNC Machining, sicela usithinte ngokukhululekile.
