Rotary Broaching on a Bridgeport
See how to Rotary Broach a hex (hexagon) form using a Bridgeport vertical milling machine and a rotary broach and rotary broach tool holder from Polygon Solutions. This video is for a prototype part with a 3/8" hex going 2x or twice the depth. The set-up is basic, but the result was a successful rotary or wobble broaching demonstration.
