  • Generating head assembly with generating head and rotary power actuator
    Patent number: 5759000
    Abstract: A generating head assembly for cutting or machining a surface on a workpiece and including a generating head mounted for relative rotation with the workpiece and with cutting or machining members having a radially advanced cutting or machining position for cutting or machining the surface of the workpiece and a radially retracted non-cutting on non-machining position; the generating head assembly includes an actuating structure for providing relative rotation between the generating head and the workpiece and a rotary motor mounted with the generating head; the rotary motor is selectively operable to rotate an actuating shaft relative to the generating head to actuate the cutting or machining members to their radially advanced and retracted positions without axial thrust loads being applied to the generating head.
    Type: Grant
