I-Wire Cut Electrical Discharge Machining (WEDM)
Isimiso sokusebenza siboniswa esithombeni esingezansi. I-electrode wire 1 inxeba kusilinda sokuthutha ngocingo 4 ihamba ngesivinini esithile ngasendleleni yokuzungezisa yesilinda sokuthutha ngocingo, bese i-workpiece 3 ifakweithuluzi lomshiniibhentshi lokusebenzela linyakaza ngokuhlobene nentambo ye-electrode ngokuvumelana ne-trajectory yokulawula enqunywe kusengaphambili yibhentshi lokusebenza. Isigxobo esisodwa se-pulse power supply sixhunywe ku-workpiece, kanti enye isigxobo ixhunywe kuntambo ye-electrode.
Kukhona njalo igebe elithile lokukhipha phakathi kwe-workpiece kanye nocingo lwe-electrode, futhi uketshezi olusebenzayo lufafazwa. Ukukhishwa kwenhlansi phakathi kwama-electrode konakalisa igebe elithile, futhi ukukhishwa kwe-pulse okuqhubekayo kusika ucezu lokusebenza lomumo nosayizi odingekayo.
Intambo ye-electrode yomshini wokusika izintambo ezinesivinini esiphansi isebenzisa intambo yethusi njenge-electrode yethuluzi, ngokuvamile ngesivinini esingaphansi kuka-0.2m/s uma uhamba ngendlela eyodwa. I-pulse voltage ye-60 ~ 300V isetshenziswa phakathi kwentambo yethusi nezinto ezicutshungulwayo njengethusi, insimbi noma i-alloy superhard, futhi igebe ligcinwa phakathi kuka-5 ~ 50um. Igebe ligcwaliswa ngamanzi angcolile (eduze namanzi acwengekile) kanye neminye imithombo ye-insulating.
Yenza ukuphuma kwenhlansi phakathi kwe-electrode ne-izinto ezicutshunguliwe, futhi omunye nomunye uyadliwa, ukugqwala, endaweni yokusebenza ye-corrosion kagesi yemigodi emincane engenakubalwa, ngokuqapha nokulawula kokulawula kwe-NC, ukukhishwa kwe-servo mechanism, ukuze into yokukhishwa ifane, ukuze izinto zokucubungula zicutshungulwe, ukuze ibe usayizi odingekayo kanye nokunemba komumo womkhiqizo. Njengamanje, ukunemba kungafinyelela ku-0.001mm, futhi ikhwalithi yangaphezulu iseduze nezinga lokugaya.
Ukukhishwa kwentambo ye-Electrodeayisasetshenziswa, kanye nokusetshenziswa kwamandla kagesi angamelani ne-electrolytic, ngokuvamile anokucushwa kwentambo okuzenzakalelayo kanye nedivayisi edonsa kanzima. Umsebenzi uzinzile, umfaniswano, i-jitter encane, ukunemba okuphezulu kwemishini, ikhwalithi enhle yendawo, kodwa ayifanele ukucubungula ukushuba okukhulu kwe-workpiece. Ngenxa yesakhiwo esinembayo sethuluzi lomshini, okuqukethwe okuphezulu kwezobuchwepheshe, intengo yethuluzi lomshini iphezulu, ngakho-ke izindleko zokusebenzisa ziphezulu.
