Rotary Broach Alignment Fixture
Shown here is a rotary broaching tool holder as held in a mill. The tool holder is set up to form a hexagon shaped hole in the block. However, the flats of the hexagon need to be parallel to the sides of the block. Therefore, a bar (or 'dog') is attached to the rotary broach tool holder spindle. A guide post is fixtured on the work piece table (shown in red). As the spinning broach holder is moved towards the hole, it will make contact with the guide post, aligning the broach for each part. Note: each time the broach is replaced, it may need to be re-aligned with the dog. More rotary broaching information is available from Polygon Solutions Inc.
