METHOD OF AND APPARATUS FOR WORKPIECE LOADING AND UNLOADING IN LATHE

摘要

In a lathe of a type employing a movable main spindle, the main spindle (2) is moved in a leftward and rightward direction (Y-axis direction) perpendicular to the longitudinal axis of the main spindle (2) after a workpiece (W) has been machined, and during the movement of the main spindle (2), the machined workpiece (W) is unloaded from the main spindle (2). At a position to which the main spindle (2) has further been moved, another workpiece (W) to be subsequently machined is loaded on the main spindle (2). The unloading of the machined workpiece (W) is carried out by a method in which the machined workpiece (W) is ejected by a workpiece eject means (7) built in a chuck (2a) in the main spindle (2).
