Abstract
A mechanical-hydraulic radial feed system for a lathe for selectively operating a selected number of tool slides in the radial direction with respect to a workpiece in the form of wire or rod which is carried by a headstock for rotation and axial movement. Each of the tool slides is normally maintained in its inoperative position and is driven toward its maximum advanced position upon energization of an associated hydraulic cylinder unit. The rate and magnitude of feed applied to the respective tool slide is profile controlled by a cam member adapted for angular motion about the axis of the workpiece and which has a cam surface operatively engaged by an arm extending from each tool slide.
