  • Repetitive rotary broaching
    Patent number: 10493541
    Abstract: A broaching tool is held during the conduct of repetitive duplicate rotary broaching operations on serially presented workpieces. The broaching tool is engaged serially with each workpiece for rotation with the engaged workpiece during a corresponding rotary broaching operation. Each workpiece has a given configuration and the broaching tool has a prescribed configuration placed at an initial orientation for establishing a broached configuration placed at a same predetermined orientation relative to the given configuration of each workpiece. Upon completion of a rotary broaching operation on a workpiece, the broaching tool is returned to the initial orientation of the prescribed configuration in preparation for a duplicate rotary broaching operation on a subsequent serially presented workpiece.
