Wire Cut Electrical Discharge Machining (WEDM)
Mfundo yogwirira ntchito ikuwonetsedwa mu chithunzi pansipa. Waya wa electrode 1 bala pa silinda yoyendetsa waya 4 imayenda pa liwiro linalake mozungulira njira yozungulira ya silinda yoyendera waya, ndipo chogwirira ntchito 3 chimayikidwa pamakina chidaworkbench imasuntha wachibale ndi waya wa elekitirodi malinga ndi zomwe zidakonzedweratu zowongolera ndi benchi. Mzati umodzi wamagetsi amagetsi umalumikizidwa ndi chogwirira ntchito, ndipo mtengo wina umalumikizidwa ndi waya wa elekitirodi.
Nthawi zonse pamakhala kusiyana kwina pakati pa chogwirira ntchito ndi waya wa elekitirodi, ndipo madzi ogwirira ntchito amapopera. Kutulutsa kwamphamvu pakati pa maelekitirodi kumawononga kusiyana kwina, ndipo kutulutsa kwamphamvu kosalekeza kumadula chogwirira ntchito cha mawonekedwe ndi kukula kwake.
Waya wama elekitirodi wamakina odulira mawaya othamanga kwambiri amagwiritsa ntchito waya wamkuwa ngati chida cha elekitirodi, nthawi zambiri pa liwiro lochepera 0.2m/s pakuyenda njira imodzi. Mpweya wothamanga wa 60 ~ 300V umagwiritsidwa ntchito pakati pa waya wamkuwa ndi zinthu zowonongeka monga mkuwa, chitsulo kapena aloyi yapamwamba kwambiri, ndipo kusiyana kumasungidwa pakati pa 5 ~ 50um. Mpatawo umadzazidwa ndi madzi opangidwa ndi deionized (pafupi ndi madzi osungunuka) ndi zina zotetezera.
Pangani spark kutulutsa pakati pa electrode ndi thekazida zokonzedwa, ndipo wina ndi mzake amadyedwa, dzimbiri, pa workpiece pamwamba pa dzimbiri magetsi osawerengeka maenje ang'onoang'ono, kudzera NC ulamuliro kuwunika ndi kulamulira, servo limagwirira kuphedwa, kuti chodabwitsa kumaliseche ndi yunifolomu, kotero kuti processing zinthu kukonzedwa, kotero kuti imakhala kukula kofunikira ndi mawonekedwe olondola a mankhwala. Pakalipano, kulondola kumatha kufika 0.001mm, ndipo mawonekedwe apamwamba ali pafupi ndi msinkhu wopera.
Kutulutsa waya wa electrodesagwiritsidwanso ntchito, komanso kugwiritsa ntchito mphamvu zopanda mphamvu zotsutsana ndi electrolytic, nthawi zambiri zimakhala ndi chingwe cholumikizira waya ndi chipangizo chokhazikika. ntchito ndi khola, yunifolomu, jitter yaing'ono, mkulu Machining mwatsatanetsatane, zabwino pamwamba, koma si oyenera pokonza makulidwe lalikulu la workpiece. Chifukwa cha mawonekedwe olondola a chida cha makina, luso lapamwamba laukadaulo, mtengo wa zida zamakina ndi wokwera, chifukwa chake mtengo wake ndi wokwera.
