A machining or processing plant (1) is provided including one or several machining stations (2) that are surrounded by a protective partition (13) and are supplied with components (4, 5) from at least one external supply (6) by a feeding mechanism (8). The feeding mechanism (8) is provided with one or several distribution vehicles (9) which can be moved between the supply (6) and the processing stations (2). The distribution vehicles (9) are equipped with a multi-shaft manipulator (10) and a device (36) for surmounting the protective partitions (13). The distribution vehicles (9) are also equipped with one or several receptacles (30) for component supports (24, 25).

A machine tool having a turning function and a milling function includes a spindle, a spindle housing supporting the spindle in a rotatable manner, a main clamp provided at the spindle, an auxiliary clamp provided at the spindle housing, and a double arm with a first gripper and a second gripper. The auxiliary clamp clamps a tool holder together with the main clamp during fixing a fixed tool. The double arm exchanges a tool holder grasped at the first gripper for another tool holder grasped at the second gripper by rotating and sliding movements. The auxiliary clamp is arranged at a position not interfering with the double arm that moves during exchanging tool holders. By such a configuration, a machine tool achieving a clamping force sufficient to withstand the load during a turning process, and that allows tool exchange in a short period of time, and a tool holder employed in such a machine tool, can be provided.
