The invention relates to a machining device for the machine-assisted production and machining of dental workpieces (16), particularly of artificial teeth and/or other dental replacement parts, the at least one workpiece (16) being clamped in at least one workpiece retainer (11) which can be raised, lowered and rotatably driven, is positioned on a rotational axis (9), and, for the purpose of machining, feeds said workpiece (16) to at least one tool spindle (4, 5, 6) that is rotationally driven and has a tool (7) secured thereto, an additional tool retainer (2, 2a, 2b) with a plurality of tools (7) arranged thereupon being associated with said workpiece retainer (11, 11a, 11b) and lying opposite on one side thereof, and a workpiece changer (22, 22a, 22b) which receives the workpieces (16, 16a, 16b, 16c) to be machined, such that they can be exchanged, being arranged on the other side of said workpiece retainer (11, 11a, 11b).

An automatic tool changer includes a cover that partitions a machining area and a non-machining area, and an opening/closing member that opens/closes an opening of the cover by turning in synchronization with rotation of a tool changer magazine. The opening/closing member includes a plate section partitions the machining area and the non-machining area at a position of the opening of the cover. In a case where the tool changer magazine performs tool replacement with respect to a tool storage magazine, the plate section closes the opening of the cover by taking a horizontal posture. In a case where the tool changer magazine performs tool replacement with respect to a main spindle, the plate section opens the opening of the cover by changing its posture from the horizontal posture to an inclined posture or a vertical posture.

The invention relates to a tool changing device (1) for a forming press (2), in particular a press brake, comprising at least one tool magazine (3, 4) and at least one transfer device (5, 6) for the transfer of the forming tools (7, 8) of the at least one tool magazine (3, 4), which are storable in the at least one tool magazine (3, 4), from the at least one tool magazine (3, 4) to the forming press (2) and in the reverse direction, wherein the at least one transfer device (5, 6) has a drivable thrust chain (9, 10) for the transmission of compressive and tensile forces.

A machine tool, which has a tool magazine for storing multiple tools and is for machining a workpiece with a tool held on a main shaft by moving the main shaft relative to the workpiece, wherein the machine tool is provided with: multiple feed shafts for moving the tool relative to the workpiece; a tool magazine drive motor for driving the tool magazine; and a manual pulse generator, which is for sending a positive or negative command pulse to the multiple feed shafts or tool magazine drive motor, the manual pulse generator being provided with a selection switch for selecting one of the multiple feed shafts or the tool magazine drive motor as the destination to which the command pulse is to be sent.

This machine tool comprises a machining chamber in which machining of a workpiece is performed, and a tool storage chamber in which a plurality of tools are stored. The machine tool is further provided with a partition which partitions the machining chamber and tool storage chamber from one another. The machine tool is positioned on the front side of the machining chamber, and is equipped with a first sliding door that moves in the width direction, and a second sliding door that is positioned on the front side of the tool storage chamber and that moves in the width direction. The first sliding door and second sliding door are positioned in such a manner that one of the sliding doors is positioned on the front side of the other sliding door, and when one of the sliding doors is opened, said door overlaps with the other sliding door.

A tool exchanger includes a variation detection unit configured to detect a variation periodically generated by turning operation of a turret; and a turret phase detection unit configured to set a tool indexing reference phase of the turret based on a detection result from the variation detection unit.

A tool magazine device includes a rail that is annularly formed and that has a separation section at a part in a circumferential direction of the rail and a holding ring that is arranged coaxially with the rail and that is rotated by a driving motor. The holding ring is provided with a plurality of holding sections that are open in an axial direction of the holding ring. The holding sections are arranged in the circumferential direction of the holding ring. A tool pot is held to be insertable into and extractable from each holding section. A conveyance unit sends out the tool pot placed in the holding section to an exchange position and sends the tool pot into the holding section from the exchange position. A roller supported by each tool pot rolls on the rail in response to the rotation of the holding ring.

A system is provided for changing and inserting tools into or presenting tools at a machine tool. The system includes at least n rotatable tool magazines for receiving a plurality of tools, where n2, which are arranged in tandem in the direction of a rotational axis. At least one of the n tool magazines can be driven independently of the other tool magazines to perform a rotational movement about the rotational axis. The system further includes a manipulator for removing the tools from the magazine. The tools are held in tool mounts along the circumference of the n tool magazines such that the longitudinal axes of the tools in each case of one of the n tool magazines are located in one plane and project from the circumference of the tool magazine, and the tools can be moved along the circumference of the respective tool magazine.
