A tool changer includes at least one tool changer unit, wherein the at least one tool changer unit includes: a tool holder that receives and holds a tool; a base member that supports the tool holder so that the tool holder can be slid along a longitudinal direction of the tool; and a moving mechanism that slides the tool holder relative to the base member.

A machine tool has a clamping device for clamping in workpieces to be machined, a work spindle which is movable relative to the clamping device, a tool magazine wherein tools for machining the workpieces are held available, the tools being selectively clamped into the work spindle, and a spindle gripper to be selectively clamped into the work spindle and being self-holding in its gripping position, said spindle gripper being held available in the tool magazine and being movable between a transfer position to the work spindle and an unloading station in which the spindle gripper releases a work piece remnant received from the clamping device.

A docking assembly and method for docking and retrieving a filament holding device includes a motor casing rod defining a recess, filament holders and docking stations. Each filament holder defines a filament receiver channel for receiving the rod and a stop member that is selectively engaged with the recess of the rod, thus coupling a filament holder to the rod for retrieval of the filament holder. Each docking station includes a deployment latch operable to rotate when the rod is inserted into the docking receiver channel so that the deployment latch urges the stop member to the deployed configuration for coupling together the rod and the filament holder. Thus, a filament holder is captured for removal from the docking station. The docking apparatus includes a release lever that operates in reverse of the deployment latch so as to release a filament holder from the rod back to its docking station.

A turret for tool machine includes: at least a turret body supported by the tool machine; at least a rotating drum supported by the turret body and supporting at least two tool holders upon which are mounted at least two rotating tools the rotating drum being mounted externally rotating around the turret body; at least an electrical spindle positioned in a recess inside the turret body; the electrical spindle extending itself around a vertical axis; the electrical spindle including a motor, a rotating shaft for the transmission of the movement associated to the motor and an engagement portion suitable for coupling to the tool holder; each tool holder extending itself along a vertical axis; the rotating drum being rotatably mounted around the turret body so as to rotate for aligning each tool holder with the engagement portion.

Disclosed herein is a system that includes a placement head, the placement head including a spindle assembly, the spindle assembly including a spindle capable of receiving one of a plurality of nozzles for attachment. The system includes a nozzle changer, the nozzle changer including a revolver capable of holding a plurality of nozzles. A position of the nozzle changer is changeable in response to movement of the spindle assembly. Further disclosed is a method of receiving and attaching nozzles with a nozzle changer.

A machine tool includes: a tool holder which includes a key groove; a spindle drive unit which includes a spindle key that can be fitted into the key groove of the tool holder and a spindle and which removably holds the tool holder; a tool exchanger which includes a grip key and a grip that holds the tool holder at a fixed position with respect to the spindle; and a numerical controller which controls the tool exchanger so as to fit and remove the tool holder with respect to the spindle, and the numerical controller controls the spindle drive unit such that when the tool holder is fitted to the spindle, in a state where the key groove of the tool holder is inserted in the spindle key, the spindle is rotated to press the spindle key to the key groove so as to determine the phase of the tool holder with respect to the spindle.

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.

A machine tool includes a machine bed, a tool clamping portion which is arranged on the machine bed and serves to clamp a workpiece on the machine tool, a swivel arm receiving portion arranged on the machine bed, a first swivel arm pivotally mounted on the swivel arm receiving portion about a first axis of rotation, a second swivel arm pivotally mounted on the first swivel arm about a second axis of rotation, a spindle carrier arm rotatably mounted on the second swivel arm about a third axis of rotation, a milling head rotatably mounted on the spindle carrier arm about a fourth axis of rotation, and a work spindle which is held on the milling head and serves to receive a tool, wherein the third axis of rotation is aligned perpendicularly or transversely to the fourth axis of rotation.

A machine tool includes: a plurality of machining units, each including: a first saddle movable in a right-left direction; a second saddle supported by the first saddle and movable in an up-down direction; and a spindle device supported by the second saddle and movable in a front-rear direction. The plurality of machining units are arranged in the right-left direction such that spindles provided in the respective spindle devices are parallel to each other. The machining tool further includes an X-axis moving mechanism that moves the first saddle in the right-left direction; and a control device that controls an operation of the X-axis moving mechanism during machining of a workpiece and during correction of a spindle spacing between the machining units. A plurality of the X-axis moving mechanisms are provided corresponding to the respective machining units.

A cutting machine includes a holder located below a spindle to hold processing targets, and an adaptor connected to a rotation shaft to rotatably support the holder. The holder includes a first holder fixed to the adaptor and including a pin insertion hole to which a fixing pin attached to a processing target is fixed, and a second holder detachably attached to the first holder and including a pin insertion hole at a position facing the pin insertion hole. The fixing pin extends in a Y-axis direction. In the Y-axis direction, a distance between a processing target fixed to the pin insertion hole and a processing target fixed to the pin insertion hole is shorter than a length of the fixing pin.
