ABSTRACT:
A broaching machine for pot-broaching teeth or ribs on the exterior of a workpiece in which the workpiece is not suitable for having sliding contact with axially extending guide surfaces in the broach to maintain the workpiece centralized therein. The machine comprises a toothed pusher on which a workpiece is centered, the teeth of the pusher registering with the teeth formed in the workpiece by broaching slots therein, at least some of the pusher teeth having end surfaces extending radially beyond the teeth formed by broaching on the workpiece, to maintain the crests of the teeth or ribs on the workpiece in clearance as the workpiece moves through the broach.
