REV BROACHING TOOL


INTERNAL BLIND KEYWAY

As illustrated in the figure, it is possible to execute a keyway inside a workpiece, even without a relief groove, using the REV BROACHING TOOL. Broaching without relief grooves considerably reduces the amount of time required per workpiece, however, it requires special inserts, with a cutting angle that is more inclined than the standard configuration, as the tool must perform a radius to lift off of the wall of the workpiece. This type of processing is used when there are difficulties in executing relief grooves inside the piece or when executing relief grooves risks weakening the structure.
To broach keyways without relief grooves, our company offers a specific programme for cnc.
