Ma'aunin duba ƙarfe na ƙarfe na ƙarfe na ƙarfe na ƙarfe na ƙarfe shine tushen samar da ƙarfe na ...

I.Yankan da Samfur:

Ana amfani da injin yanke ƙarfe don yanke samfuri. Ana amfani da sanyaya ruwa a duk lokacin yankewa don hana canje-canje a tsarin ƙarfe na samfurin da hanyoyin ɗaukar samfuri marasa kyau suka haifar. Musamman, ana iya zaɓar samfuran daban-daban na injunan yanke ƙarfe don yankewa da ɗaukar samfuri bisa ga girman samfurin da kuma hanyoyin atomatik da ake buƙata.

II.Samfurin Nika da Gogewa:

Bayan yankewa, ana niƙa samfurin (don kayan aiki marasa tsari, ana buƙatar injin ɗagawa don yin samfurin) a kan injin niƙa da goge samfurin ƙarfe ta amfani da takardun yashi masu girman grit daban-daban daga mai kauri zuwa mai laushi. Ana iya zaɓar nau'ikan takardun yashi uku ko huɗu don niƙa bisa ga kayan aiki daban-daban, kuma ana buƙatar zaɓar saurin juyawa na injin niƙa da gogewa bisa ga samfurin.

Ana goge samfurin bayan niƙa takarda mai laushi ta amfani da zane mai laushi mai laushi tare da mahaɗin goge lu'u-lu'u. Ana iya daidaita saurin juyawa na injin niƙa da gogewa gwargwadon aikin da aka yi.
