Abstract
In an automatic transfer machine tool with circular supply movement for workpieces to be sequentially worked on in respectively separate working stations (I-V), a stepwise indexable workpiece holder (10) is journalled on a center post (8), the workpiece holder (10) having clamping devices (11) arranged thereon for the workpieces. In order to be able to accept high working forces at the working stations (I-V) without danger of impairment of working accuracy, and to obtain good accessibility of the workpieces and of the tools of the machining units (14, 15, 16), the automatic transfer machine tool has a rigid cage (1) with two wall portions (2, 3) which are located opposite from each other and spaced from each other and rigidly interconnected, the upper wall portion (3) having the workpiece holder (10) rotatably journalled on the upper wall portion (3) within the interior of the cage, and the cage is seated with the lower wall portion (3) on the center post (8), the machining units (14, 15, 16) being inserted in the region of the respective separate working stations (I-V) in the cage (1).
