Abstract
A machine tool has at least one working spindle, in which a tool receptacle for tool holders is provided. Furthermore, there is a tool-changing arm with a gripper, for a tool holder in order to transfer this tool holder between its magazine position, which is spaced apart from the tool receptacle, and its working position, in which the tool holder can be clamped into the tool receptacle. Orientation means are provided between the gripper and the tool holder supported by it and secure the tool holder in a nonrotatable manner on the gripper at least during its transfer between the magazine position and the working position and release it after it has been clamped into the tool receptacle, with the result that the tool holder can be rotated in relation to the gripper.
