Operation in which a cutter progressively enlarges a slot or hole or shapes a workpiece exterior. Low teeth start the cut, intermediate teeth remove the majority of the material and high teeth finish the task. Broaching can be a one-step operation, as opposed to milling and slotting, which require repeated passes. Typically, however, broaching also involves multiple passes.
Cutting Tool Engineering visited with Abel Rodrigues, sales engineer, Somma Tool Co., during IMTS 2016 as he provided the play-by-play for a video demonstration of external and internal rotary broaching.
