ABSTRACT:
A method and system for continuously grinding tubing to finished cannulae, where the tubing is loaded in a carrier and the carrier is continuously guided past stations which cut the primary bevel, finish the butt end, clean the cut ends, and then make lancelet cuts on the primary bevel. The system further includes a cannula carrier and guide system which permits the cannulae to be unclamped, rotated and reclamped prior to each lancelet cutting station.
