Kuzunguruka bifasha ibice bizunguruka nk'inkoni cyangwa ibiti muri sisitemu ya mashini, no kwimura imitwaro ya axial na radial biva mumitwaro yimitwaro kugeza kumiterere iyishyigikira.Ikintu cyoroshye cyane ni icyuma gisanzwe, kigizwe nigiti kizunguruka mu mwobo.Mugabanye guterana amagambo.Mu mipira yumupira hamwe nudukingirizo, kugirango tugabanye umuvuduko wo kunyerera, ikintu kizunguruka cyangwa umupira uzunguruka ushyizwe hagati yumusiganwa cyangwa ikinyamakuru cyinteko.Ibishushanyo bitandukanye bishobora kwuzuza neza ibisabwa bitandukanye kugirango bishoboke gukora neza no kunoza kwizerwa no kuramba.
Ijambo kubyara riva ku nshinga “kubyara”.Kwitwaza ni imashini yemerera igice kimwe gushyigikira (ni ukuvuga inkunga) ikindi gice.Ikintu cyoroshye cyane ni ubuso bwo hejuru.Mugukata cyangwa gukora ibice, imiterere, ingano, ubukana hamwe nubuso bwubuso bigenzurwa kuburyo butandukanye.Ibindi byuma nibikoresho byigenga byashyizwe kumashini cyangwa ibice byimashini.Mu bikoresho bifite ibyangombwa bisabwa cyane kugirango bisobanuke neza, gukora ibicuruzwa bitomoye bigomba kuba byujuje ubuziranenge bwikoranabuhanga rigezweho.
