A system for changing and presenting one or more tools of a plurality of tools at a working spindle of a machine tool, the system comprising:
- n rotatable tool magazines for receiving the plurality of tools, where n≥2, and the n tool magazines are arranged consecutively along a rotational axis, the rotational axis of the n tool magazines being arranged in a horizontal direction parallel to a floor space on which the machine tool stands, wherein at least one of the n tool magazines can be driven by a drive independently of the other one of the n tool magazines to perform a rotational movement about the rotational axis, and wherein each of the n tool magazines has a respective outer circumferential surface;
- and
- a manipulator configured to remove the one or more tools of the plurality of tools from the n tool magazines and to deliver the one or more removed tools to the working spindle of the machine tool,
- wherein the plurality of tools are held in tool mounts provided in and along the respective outer circumferential surfaces of the n tool magazines such that longitudinal axes of the plurality of tools in each of the n tool magazines are located in a plane and project from the outer circumferential surface of the associated tool magazine of the n tool magazines;
- wherein the n tool magazines, or the n tool magazines with the exception of one of the n tool magazines, each have in one location on their respective outer circumferential surfaces a respective free place without tools through which the manipulator can be moved in a first horizontal direction parallel to the horizontal rotational axis of the n tool magazines,
- wherein to remove the one or more tools of the plurality of tools from a selected tool magazine of the n tool magazines, at least one or more of the n tool magazines which are arranged along the rotational axis between the selected tool magazine and the manipulator are rotated about the rotational axis into a predetermined position such that their free places along the rotational axis provide access for the manipulator to horizontally traverse therethrough via movement of the manipulator in the first horizontal direction, and
- wherein the manipulator performs a linear horizontal movement in the first horizontal direction through the free places from a position located outside of the n tool magazines, along a passage formed by the free places, and up to the selected tool magazine, and the manipulator performs a linear horizontal movement in the first horizontal direction through the free places from the selected tool magazine to the working spindle of the machine tool to transfer the one or more removed tools to the working spindle of the machine tool and to directly, by the manipulator, deliver the one or more removed tools to the working spindle of the machine tool, the n rotatable tool magazines being arranged such that the working same height above the floor space as a height of the horizontally arranged rotation axis of the n rotatable tool magazines above the floor space.
