A workpiece feed device for lathes wherein an elongated workpiece is supported solely at the opposed end areas thereof. The workpiece extends through the lathe spindle feed opening with one end being clampingly engaged thereat and the other end being supported by a workpiece pusher. This pusher is selectively movable by drive means linearly along a workpath so as to sequentially feed the workpiece into the lathe. The pusher is supported by a plurality of roller sets so that it may freely rotate coaxially about the workpath and the roller sets are positioned in a generally surrounding relationship with the pusher so that any lateral pusher movement relative to the workpath is substantially limited or eliminated. Also, the roller sets and pusher are dimensioned to cooperate with each other at some predetermined radial distance from the workpath so that the workpiece is supported over its length solely at the opposite end areas thereof. The pusher is receivable in the lathe spindle opening to complete a workpiece feeding operation.
