I-Wire Cut Electrical Discharge Machining (WEDM)
Umgaqo wokusebenza uboniswe kumzobo ongezantsi. I-electrode wire 1 inxeba kwi-cylinder yokuthutha i-4 ihamba ngesantya esithile ecaleni kwendlela yokujikeleza ye-cylinder yokuthutha ucingo, kunye ne-workpiece 3 efakwe kwiisixhobo somatshiniibhentshi yokusebenzela ishukuma ngokunxulumene nocingo lwe-electrode ngokwendlela yolawulo esele imiselwe yi-workbench. Ipali enye ye-pulse power supply ixhunyiwe kwi-workpiece, kwaye enye i-pole ixhunyiwe kwi-electrode wire.
Kuhlala kukho i-gap ethile yokukhupha phakathi kwe-workpiece kunye nocingo lwe-electrode, kwaye ulwelo olusebenzayo lufafazwa. Ukukhutshwa kwe-spark phakathi kwe-electrode kudla i-gap ethile, kwaye ukukhutshwa kwe-pulse okuqhubekayo kunqumla i-workpiece yesimo esifunekayo kunye nobukhulu.
Intambo ye-electrode yomshini wokusika i-low-speed machine isebenzisa ucingo lobhedu njengesixhobo se-electrode, ngokuqhelekileyo ngesantya esingaphantsi kwe-0.2m / s ukuhamba kwendlela enye. I-voltage ye-pulse ye-60 ~ 300V isetyenziswe phakathi kocingo lobhedu kunye nezinto ezicwangcisiweyo ezifana nobhedu, insimbi okanye i-alloy superhard, kwaye i-gap igcinwa phakathi kwe-5 ~ 50um. I-gap izaliswe ngamanzi adibeneyo (kufuphi namanzi adibeneyo) kunye nezinye i-insulating media.
Yenza ukukhutshwa kwe-spark phakathi kwe-electrode kunye ne-imathiriyeli esetyenzisiweyo, kwaye enye nenye idliwe, i-corrosion, kwindawo yokusebenza yombane we-corrosion yombane wemigodi emincinci encinci, ngokubeka iliso kunye nolawulo lwe-NC, ukuphunyezwa kwe-servo mechanism, ukwenzela ukuba i-dicharge phenomenon ifanane, ukwenzela ukuba izinto zokucubungula ziqhutywe, ukuze ibe bubungakanani obufunekayo kunye nokuchaneka kwemilo yemveliso. Okwangoku, ukuchaneka kunokufikelela kwi-0.001mm, kwaye umgangatho womhlaba usondele kwinqanaba lokugaya.
Electrode wire dischargeayisasetyenziswa, kunye nokusetyenziswa non-resistance anti-electrolytic unikezelo lwamandla, ngokubanzi ngocingo oluzenzekelayo umsonto kunye noxinzelelo rhoqo isixhobo. Umsebenzi uzinzile, ufanayo, i-jitter encinci, ukuchaneka okuphezulu kwe-machining, umgangatho omhle womphezulu, kodwa awufanelekanga ukusetyenzwa kobunzima obukhulu be-workpiece. Ngenxa yesakhiwo esichanekileyo sesixhobo somatshini, umxholo ophezulu wezobugcisa, ixabiso lesixhobo somatshini liphezulu, ngoko ke iindleko zokusetyenziswa ziphezulu.
