Abstract:
A method removes a fuel injector pole piece from bar stock and provides a cutoff tool having a first cutting surface and a second cutting surface separate from the first cutting surface. The pole piece and bar stock are caused to rotate about a longitudinal axis. The tool is advanced with respect to the pole piece so that the first cutting surface severs the pole piece from the bar stock and defines an unfinished end surface of the pole piece, with a certain cutting force being exerted on the tool. The tool is further advanced with respect to the pole piece so that the second cutting surface removes material from the unfinished end surface to define a finished end surface of the pole piece, with a cutting force on the tool being substantially less than the certain cutting force.
