Abstract
A bottom-loading pot broaching machine has a pot broach vertically mounted on a horizontal face of a base support structure to symmetrically distribute loading forces to the machine. This structure also enables loading and unloading arms to be mounted to the pot broach so as to be mechanically coupled and phased to allow both loading and unloading of the pot broach during a single cycle. A magnetic escapement mechanism is mounted proximately to the unloading arm to magnetically retain a finished workpiece for unloading by the unloading arm.
