Umshini wokugunda umshini osebenzisa i-blade eyodwa ukwenza ukunyakaza okuhambisanayo komugqa ukuze usike ipuleti elihlobene nenye i-blade. Ngokuhambisa i-blade engenhla kanye ne-blade ephansi elungisiwe, igebe le-blade elinengqondo lisetshenziselwa ukusebenzisa amandla okugunda kumapuleti ensimbi anobukhulu obuhlukahlukene ukuze aphule futhi ahlukanise amapuleti ngokuvumelana nobukhulu obudingekayo. Umshini wokugunda ungomunye wemishini yokubumba, umsebenzi wawo oyinhloko imboni yokucubungula insimbi. Imikhiqizo isetshenziswa kabanzi ekukhiqizeni insimbi yensimbi, izindiza, imboni ekhanyayo, i-metallurgy, imboni yamakhemikhali, ukwakhiwa, olwandle, izimoto, amandla kagesi, izinto zikagesi, umhlobiso kanye nezinye izimboni ukuhlinzeka ngemishini ekhethekile kanye namasethi aphelele wemishini.
