Wire Cut Electrical Discharge Machining (WEDM)
Nheyo yekushanda inoratidzwa mumufananidzo uri pasi apa. Iyo electrode waya 1 ronda pawaya yekutakura cylinder 4 inofamba pane imwe kumhanya ichitevedza nzira yekutenderera yewaya yekutakura silinda, uye workpiece 3 yakaiswa pamuchina mudziyoworkbench inofamba inoenderana newaya ye electrode zvinoenderana neyakafanotemerwa kudzora trajectory nebhenji rebasa. Rimwe danda remagetsi emagetsi rinobatanidzwa kune workpiece, uye imwe danda inobatanidzwa kune electrode wire.
Pane nguva dzose pane imwe gap yekubuda pakati peworkpiece newaya ye electrode, uye mvura inoshanda inopfapfaidzwa. Iyo spark discharge pakati pema electrode inoshatisa imwe gap, uye inoenderera pulse discharge inocheka iyo workpiece yechimiro chinodiwa uye saizi.
Waya ye electrode yemuchina wekucheka wakaderera-inomhanya inoshandisa waya yemhangura sechokushandisa electrode, kazhinji nekumhanya isingasviki 0.2m/s kune imwe-nzira kufamba. Iyo pulse voltage ye60 ~ 300V inoshandiswa pakati petambo yemhangura uye zvinhu zvakagadziriswa semhangura, simbi kana superhard alloy, uye gaka rinochengetwa pakati pe5 ~ 50um. Iyo gap yakazadzwa nemvura yakasvibiswa (pedyo nemvura yakasvibiswa) uye mamwe ma media ekudzivirira.
Ita spark discharge pakati pe electrode neiyoprocessed material, uye imwe neimwe inopedzwa, corrosion, pane workpiece pamusoro pemagetsi emagetsi asingaverengeki makomba maduku, kuburikidza neNC control monitoring uye kutonga, servo mechanism execution, kuitira kuti chiitiko chekubuda ive yunifomu, kuitira kuti zvinhu zvekugadzirisa zvigadziriswe, kuitira kuti ive saizi inodiwa uye chimiro chakarurama chechigadzirwa. Parizvino, iyo chaiyo inogona kusvika 0.001mm, uye mhando yepamusoro iri padyo nedanho rekukuya.
Electrode wire dischargehaichashandiswi, uye kushandiswa kweasina-kupokana anti-electrolytic magetsi, kazhinji ine otomatiki waya shinda uye inogara ichinetsa mudziyo. Iro basa rakagadzikana, yunifomu, jitter diki, yakakwira machining precision, yakanaka yepamusoro yemhando, asi haina kukodzera kugadzirisa hukuru hwakakura hweworkpiece. Nekuda kweiyo chaiyo chimiro chechishandiso chemuchina, yakakwira tekinoroji yemukati, mutengo wemuchina wemuchina wakakwira, saka mutengo wekushandisa wakakwira.
