W1 koyera 0,18 tungsten waya EDM podula
Inde, waya EDM (makina otulutsa magetsi) angagwiritsidwe ntchito kudula tungsten. Tungsten ndi chinthu cholimba, chosungunuka kwambiri chomwe chingakhale chovuta kudula pogwiritsa ntchito njira zachikhalidwe. Komabe, makina a EDM amawaya ndi abwino kwa kudula tungsten chifukwa cha kuthekera kwawo kudula molondola mawonekedwe ovuta muzinthu zolimba.
Mu waya EDM, waya wochepa thupi (omwe nthawi zambiri amapangidwa ndi mkuwa kapena tungsten) amagwiritsidwa ntchito podula chogwirira ntchito. Podula tungsten pogwiritsa ntchito waya EDM, ndikofunikira kuganizira izi:
1. Kusankha mawaya: Waya wa Tungsten ungagwiritsidwe ntchito ngati waya wodulira mu makina opangira magetsi odula mawaya kuti adule zida zolimba monga tungsten. Waya wa Tungsten adasankhidwa chifukwa champhamvu yake yolimba komanso kukana kutentha ndi kuyabwa.
2. Mapangidwe a Mphamvu: Makina anu a EDM akuyenera kukhazikitsidwa pazigawo zoyenerera zamagetsi kuti atsimikizire kuchotsa zinthu zogwira mtima pamene mukusunga umphumphu wa tungsten filament.
3. Tsukani ndi kuchotsa zinyalala: Podula tungsten, kupukuta koyenera ndi kuchotsa zinyalala za workpiece ndikofunikira kuti mukhalebe olondola ndikupewa kusweka kwa waya.
4. Kuthamanga kwa Waya ndi Ulusi: Kukanikizana koyenera ndi ulusi wa waya wa tungsten n'kofunika kwambiri kuti tipeze zotsatira zodula bwino komanso zosasinthasintha.
Podula tungsten ndi makina a EDM a waya, ndikofunika kutsatira njira zabwino kwambiri ndikuganizira za makhalidwe enieni a tungsten kuti mukwaniritse zotsatira zabwino zodulidwa.
Waya makulidwe a EDM (Electrical Discharge Machining) kudula kungasiyane kutengera ntchito yeniyeni ndi zinthu zomwe zikukonzedwa. Nthawi zambiri, waya wa EDM awiri nthawi zambiri amakhala 0.1 mm mpaka 0.3 mm (0.004 inchi mpaka 0.012 inchi). Komabe, waya wokhuthala kapena woonda angagwiritsidwe ntchito pazinthu zinazake.
Pamadulidwe aukali kapena kuchotsa zinthu mwachangu, mawaya okhuthala (0.25 mm mpaka 0.3 mm) atha kukhala abwino. Waya wokhuthala amatha kugwira mafunde okwera kwambiri ndipo ndi yabwino kuchotsa zinthu mwachangu.
Kwa mabala abwino, mawonekedwe ovuta, kapena kulolerana kolimba, mawaya ocheperako (0.1 mm mpaka 0.2 mm) amagwiritsidwa ntchito. Waya wocheperako amalola macheka olondola komanso atsatanetsatane, kupangitsa kuti ikhale yoyenera kugwiritsa ntchito zomwe zimafuna kulondola kwambiri.
Posankha makulidwe a waya kwa kudula kwa EDM, zinthu monga zinthu zomwe zikukonzedwa, liwiro lodulira lomwe limafunikira komanso kumalizidwa kwapamwamba kumafunika kuganiziridwa. Kuonjezera apo, mphamvu zenizeni za makina a EDM ndi malingaliro a wopanga ziyenera kuganiziridwa pozindikira makulidwe oyenera a waya pa ntchito yoperekedwa.
