Umshini wokugunda ngumshini osebenzisa ibala elilodwa ukwenza ukubuyisa ukunyakaza okuqondile ukusika ipuleti elihlobene nelinye. Ngokuhambisa ibala elingaphezulu kanye ne-blade elingaphansi elimisiwe, kusetshenziselwa igebe elinengqondo lokusebenzisa amandla okugunda amapuleti wensimbi ngobukhulu obuhlukahlukene ukuhlukana nokuhlukanisa amapuleti ngokuya ngosayizi odingekayo. Umshini wokugunda ungomunye wemishini eyokwakhayo, umsebenzi wawo oyinhloko ngumkhakha wensimbi wensimbi. Imikhiqizo isetshenziswa kabanzi ekukhiqizeni insimbi ye-Sheet Metal, indiza, imboni ekhanyayo, i-metallurgy, embonini yamakhemikhali, ukwakhiwa kwezimoto, izimoto kanye nezinye izimboni, ezinye izimboni zokuhlinzeka ngemishini ekhethekile kanye namasethi aphelele wemishini.
