Abstract
The trimmed edges of cylindrical metal bodies are freed of internal burrs by shifting the body axially on the support means to move the burr-bearing edge from the cutting element to a cylindrical surface portion, following which an ironing tool flattens the burr against the surface so as to effect its fracture and removal from the body.

Apparatus for trimming and deburring the edges of cylindrical metal bodies, comprising:
- support means upon which a cylindrical metal body may be mounted, said support means including a cutting element and a cylindrical portion;
- a cutting tool disposed adjacent said cutting element and being adapted to cooperate therewith to sever an edge portion of a metal body mounted on said support means, and to form an inwardly-directed burr at the newly-formed edge of the body;
- an ironing tool disposed adjacent said cylindrical portion of said support means and being adapted to cooperate therewith to iron a portion of a metal body disposed thereon;
- and
- means for controllably shifting a metal body axially on said support means to move a portion of the body from said cutting element to a position on said cylindrical portion of said support means, so that, following severance and internal burr formation, the burr-bearing portion of the body may be moved to said cylindrical portion of said support means, to permit ironing of the burr thereat, and to thereby effect its fracture and removal.
