Hassay Savage Index Broaching

An Alternative To Full Form Rotary Broaching

Index Broaching to Generate Full Polygon Forms

This broaching process involves a stationary spindle with orientation and lock capabilities. Once hole preparation is completed, it is then punched with a partial form of the shape that is to be generated. The tool form is indexed on a CNC machine by making imprints of the tool to the proper depth while the part is created to the full form desired. Index Broaching can be performed on multiple machining applications. For instance, the CNC machining centers are the most common for Index Broaching: Lathes Swiss Style Machines Vertical Machining Centers Typical applications include: Hexagonal Double Hexagonal 6 Lobe / Hexalobe Square Keyways / Slots / Splines Required Tooling Includes: 90 Spot / Chamfer Tool Desired Pilot Drill Index Punch Broach CNC Turning Machine The CNC Turning Center performs each of these operations on the work piece before the Index Broach makes contact with the work piece. Face off the work piece. Countersink a pilot hole for the drill bit, slightly larger than the across corner dimensions of the broach. Drill pilot hole approximately 2 percent larger for hex and 10 percent larger for square than the size across the flats. Hole is now prepared for Index Broach.
