Lisebelisoa tsa cobalt ha li sebetse joaloka tšepe e sa hloekang. Ba sebetsa ka thata ka mokhoa o mabifi, ba tsamaisa mocheso hampe, 'me ba batla maano a lisebelisoa a leka-lekaneng ho tsoa ha chip le taolo ea mocheso. Feme ea 'nete ea 6 ea cobalt alloy ha e na mechini ea CNC feela - e na le liheke tse ts'eletseng tse koaletsoeng:
