Kuzunguruka ibyuma, bizwi kandi nko kuzunguruka cyangwa kuzunguruka, ni inzira yo gukora ibyuma bikubiyemo kuzenguruka disiki cyangwa umuyoboro w'icyuma ku musarani mugihe ushyizeho igitutu nigikoresho cyo kugikora muburyo bwifuzwa.Inzira isanzwe ikoreshwa mugukora silindrike cyangwa conique nkibikombe, vase, n'amatara, hamwe na geometrike igoye nka hemispheres na paraboloide.
Mugihe cyo kuzunguruka ibyuma, disiki yicyuma cyangwa umuyoboro bifatirwa kumusarane hanyuma bikazunguruka ku muvuduko mwinshi.Igikoresho, cyitwa spinner, noneho kanda hejuru yicyuma, bigatuma gitemba kandi gifata imiterere yigikoresho.Kuzunguruka birashobora gufatwa n'intoki cyangwa bigashyirwa kumusarani.Inzira isubirwamo inshuro nyinshi, hamwe nuburyo buhoro buhoro bunonosorwa na buri pass kugeza igihe ifishi yanyuma igerwaho.
Kuzunguruka ibyuma birashobora gukorwa hifashishijwe ibyuma byinshi, harimo aluminium, umuringa, umuringa, ibyuma bitagira umwanda, na titanium.Bikunze gukoreshwa mugukora ibice byo mu kirere, ibinyabiziga, n’urumuri, ndetse no mu gushushanya no mu buhanzi.
