Abstract

A workpiece handling device for a machine tool having at least one work station disposed on the frame of the machine tool, wherein workpieces are held in workpiece holders during machining comprises a transfer means and a feeding means. The transfer means has a plurality of engaging means defining a plurality of positions along a first axis. A feeding means has two rows of engaging means formed in a plurality of columns. The rows are parallel to the first axis and the columns have parallel axis which interest the first axis and the centerline axis of a respective one of the work stations. The transfer means and the feeding means move in an alternating reciprocal manner to transfer the workpieces from a feeding station where workpieces are inserted, through the machine work stations, to a discharge station where the machined workpiece is ejected and back to the feed station in a cyclical manner.
