ABSTRACT:
Riveting apparatus wherein a planetary roller screw delivers the high forces required for actuating the fastener upset tooling. In order that precise control of the entire upset operation may be obtained, a servo-controlled electric motor operates the actuator. In order that different machining operations may be performed on a workpiece without having to provide an actuator for each tool, the tools are engaged in turn by the actuator for performing riveting and other machining in succession.
