Abstract:
1. Apparatus for machining parallel surfaces on a rotating workpiece, comprising: a metal-cutting tool, and means including a jaw for advancing the metal-cutting tool toward a material-removal position of a workpiece; a base; a shaft mounted on the base for axial motion; a power cylinder mounted on the base, the power cylinder having a movable piston rod; a fulcrum mounted on the base; a lever mounted on the fulcrum and engageable with the shaft for moving the shaft in a first axial direction, the lever being engageable with the piston rod to be pivoted about said fulcrum as the piston rod is moved in a power stroke; a spring washer having a central opening supported on said shaft to bias the shaft in an opposite axial direction; and structure connecting the shaft to the metal-cutting tool to move same away from the material-removal position, against the bias of the spring washer as the lever moves said shaft in said first axial direction.
