Umshini wokwenza umqulu wesitimela umshini osetshenziselwa ukukhiqiza amathrekhi kaloliwe.Kungumshini wokwenza ama-roll owenza insimbi ibe yimichilo emide eqhubekayo ye-uniform cross-section.Inqubo ihilela ukuphakela insimbi yeshidi ngochungechunge lwamarola agoba kancane kancane futhi alolonge izinto zibe iphrofayili oyifunayo.Izinhlobonhlobo zezinqubo nezinhlelo zokukhiqiza zingahlanganiswa emishinini yokwakha i-orbital roll ukuze kube lula ukusebenza kokukhiqiza.
Ngokusebenza okushelelayo nokusebenza okungenakuqhathaniswa, imishini yethu yokwakha i-orbital roll izoguqula indlela ocabanga ngayo ngomsebenzi wensimbi.Ubuchwepheshe bethu obuphambili kanye nochwepheshe abanolwazi baqinisekisa ukuthi uthola imiphumela oyifunayo isikhathi nesikhathi.
