The vertical axis and the two horizontal axes are orthogonal to one another. The at least one first tool magazine, a tool set is provided that comprises a plurality of tools for machining, wherein the tools can be selectively clamped in the tool spindle. The at least one second tool magazine, a tool set is provided that comprises a plurality of tools for machining, wherein the tools can be selectively clamped in the tool spindle. Only one tool magazine of the at least one first tool magazine and the at least one second tool magazine is active at a time, so that exclusively the tool set from the respective active tool magazine is used for machining the clamped workpiece. There is also provided a corresponding method of machining workpieces.

An arrangement for processing workpieces includes at least one processing machine, a machine magazine assigned to a respective processing machine for accommodating processing tools, and a robot arranged on a driverless base frame. Processing tools may be supplied to and/or removed again from the machine magazine using the driverless base frame. The driverless base frame is additionally provided with a temporary magazine for accommodating processing tools.

A tool magazine for tools of a machine tool for processing workpieces includes a first magazine unit that is close to a processing station of the machine tool and a second magazine unit that is remote from the processing station of the machine tool. The second magazine unit includes a permanent tool carrier and a temporary tool carrier. The permanent tool carrier is permanently accessible to a tool handling device. The temporary tool carrier is temporarily accessible to the tool handling device.

A machine tool includes a tool spindle, a tool intermediate device, and a tool storage which includes first tool magazines, a first tool magazine support mechanism, an additional first tool magazine support mechanism, and a tool carrier. The first tool magazine support mechanism includes a first shaft to support at least one of the first tool magazines to be rotatable about a first rotation axis. The additional first tool magazine support mechanism includes an additional first shaft to support at least one of the first tool magazines to be rotatable about an additional first rotation axis. The tool carrier includes a first guide extending along the first and additional first rotation axes, a second guide extending along a line connecting the first and additional first rotation axes, and a lift configured to move along the first guide. The first guide is movable along the second guide.

This machine tool system is provided with a tool holder adaptor that has a flange having formed therein: a hole part that contains a tool holder; and an engagement part that engages with a hand of a self-propelled robot, wherein when transporting the tool holder to a machine tool from a tool storage that contains a plurality of tool holder adaptors, the self-propelled robot grasps the tool holder adaptor to transport the tool.

This method, for controlling a machine tool using a tool holder to which a coolant pipe is attached, includes: a step of detecting, in response to a signal indicating that a tool is prepared on a tool loading station of the machine tool, whether or not an abnormality has occurred in attaching the coolant pipe to the tool holder of the tool while the tool holder is at the tool loading station; and a step of issuing an alarm when the abnormality is detected in the step of detecting the occurrence of the abnormality.

A machine tool including a first and a second tool magazine, wherein a tool for machining a workpiece can be received from the first tool magazine and a tool from the second tool magazine can be transferred into the first tool magazine, and wherein one of the tools includes a multiple tool that can be fitted with a plurality of tools prior to the machining. A method for controlling a machine tool includes the steps of detecting workpieces to be machined, determining the tools required for machining the detected workpieces and determining the tools, with which the multiple tool is to be fitted.

A tool magazine for tools of a machine tool for processing workpieces includes a first magazine unit that is close to a processing station of the machine tool and a second magazine unit that is remote from the processing station of the machine tool. The second magazine unit includes a permanent tool carrier and a temporary tool carrier. The permanent tool carrier is permanently accessible to a tool handling device. The temporary tool carrier is temporarily accessible to the tool handling device.

The invention relates to a bending tool storage device (1) for storing bending tools (2), comprising at least one storage unit (3), which comprises an outer tool storage (4) which is ring-shaped or partial-ring-shaped and has a plurality of guide rails (14) for holding and guiding bending tools (2), characterized in that the storage unit (3) comprises at least one inner tool storage (5, 6) which is arranged inside the outer tool storage (4) and has a plurality of guide rails (15, 16) for holding and guiding bending tools (2), and in that the outer tool storage (4) and the inner tool storage (5, 6) are rotatable relative to one another, wherein, in different positions of relative rotation between outer tool storage (4) and inner tool storage (5), at least one guide rail (14) of the outer tool storage (4) is in each case in aligned orientation with another guide rail (15, 16) of the inner tool storage (5, 6).

A machine tool is provided with two vertically oriented tool spindles that are arranged to hold tools and that are movable vertically in a first direction and horizontally in a second direction orthogonal to the first direction. Furthermore, the machine tool is provided with two workpiece support devices for clamping workpieces in place. At least one of the two workpiece support devices is movable horizontally in a third direction orthogonal to the first and the second direction. The two tool spindles and the two workpiece support devices are mounted on a common machine frame with a common working space, wherein the two tool spindles are movable parallel to one another in the second direction. The two tool spindles are facing one another.
