Abstract
A machine tool has a working spindle in which a tool receptacle for tool holders is provided. Furthermore, there is at least one tool-changing arm with a gripper in which a tool holder is held in a peripheral alignment with respect to the gripper 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. A positioning indicator is provided for the peripheral alignment of the tool holder, the indicator indicating a misalignment between the tool holder and gripper.
Claims29
A machine tool having at least one working spindle, in which working spindle a tool receptacle for tool holders is provided, and having at least one tool-changing arm with a gripper, in which gripper a tool holder is held in a peripheral alignment with respect to the gripper 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, wherein a positioning indicator is provided for peripheral alignment of the tool holder, the indicator indicating a misalignment between the tool holder and gripper, wherein the positioning indicator is assigned a position sensor which recognizes the peripheral alignment of the tool holder with respect to the gripper.
The machine tool of claim if 1, wherein the position sensor is arranged on an actuating unit for the tool-changing arm.
A machine tool
- having at least one working spindle, in which working spindle a tool receptacle for tool holders is provided, and
- having at least one tool-changing arm with a gripper, in which gripper a tool holder is held in a peripheral alignment with respect to the gripper 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,
- wherein a positioning indicator is provided for the peripheral alignment of the tool holder, the positioning indicator indicating a misalignment between the tool holder and gripper,
- the positioning indicator being assigned to a tool sheath, which is arranged on the tool-changing ann and by which the tool holder is at least partially covered in its magazine position,
- wherein the positioning indicator is assigned a position sensor which recognizes whether the tool holder has reached the magazine position in the tool sheath.
