ABSTRACT:
A hydraulic cam feed unit is provided for moving a tool slide linearly towards and away from a workpiece. The feed unit comprises a hydraulic advance cylinder having a double rod, one end of which is connected to the tool slide to move the tool slide towards and away from the workpiece. A cam engaging member is connected to the opposite end of the double rod for linear movement with the double rod and the tool slide, and a cam is provided in selective engagement with the cam engaging member. A hydraulic feed cylinder has a single rod connected to the cam for linearly reciprocating the cam. When the cam is in engagement with the cam engaging member, the linear movement of the cam controls the linear movement of the tool slide.
