Abstract

The invention relates to a machine tool having a workpiece carrier (6) and one or a plurality of tool carriers (4) arranged in application trays of the machine tool. The machine tool is used to machine workpieces (16), in particular connecting rods, said workpieces being machined in a machining chamber (20) of the machine tool. The workpiece carrier is loaded and/or unloaded by way of a workpiece feeder device (8). To that end, the workpiece feeder device is provided with a carrier body (14), on which machined and non-machined workpieces can be arranged and exchanged by the workpiece carrier during a loading and unloading process. For a flexible arrangement, in particular for a space-saving arrangement of the workpiece feeder device with respect to the machine tool, the carrier body can be moved, in particular pivoted, along at least two machine axes. Thus, the carrier body can be flexibly inserted into the machining chamber from an external side of the machine tool.
