ABSTRACT:
A bar stock feed apparatus for a machine tool has a bar stock support tube for alignment, in use with a workpiece carrier of the machine tool. A fluid pressure-actuated feed means in the form of a pusher tube slides within the tube and is driven by a piston to feed the bar when desired. Fluid is introduced into the support tube forwardly of the piston, and independently of the fluid supplied to the piston, to cushion the bar stock within the tube 15 and thereby minimize undesirable noise during operation.
