A tool magazine (40) is able to move among a machining position where a tool (2) attached to a spindle (30) machines a workpiece, a tool exchange position where the tool (2) attached to the spindle (30) is exchanged, and a retreat position where an automated workpiece carrying device is not disturbed in placing or removing of the workpiece with respect to a workpiece placing part (20). The workpiece is placed on the workpiece placing part (20) from above or removed upward from the workpiece placing part (20) by the automated workpiece carrying device.

A dust collection assembly for a computer numerical control (CNC) cutting machine includes an adapter configured to couple to an arm of the CNC cutting machine and a head telescopically coupled to the adapter by a plurality of nested members. The CNC cutting machine includes the arm supporting a spindle and a tool holder coupled for co-rotation with the spindle. Each of the plurality of nested members are collapsible relative to each other. The head is movable between an extended position in which the nested members are configured to surround the tool holder and a tool bit, and a retracted position in which at least some of the nested members are telescopically received in the adapter. The head defines an inlet fluidly connected to the plurality of nested members when the head is at least in the extended position. The inlet is configured to fluidly connect to a vacuum.

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).

A docking assembly 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 position compensation system of a tool changer includes a storage unit for storing a coordinate indicating a reference position of a turret, a rotary position coordinate detector for detecting the rotary position coordinate of the turret, a compensation necessity determiner for determining whether or not it is necessary to perform a rotational compensation to return the turret to the reference position, in accordance with a rotational deviation of the detected rotary position coordinate from the stored rotary position coordinate, and a compensation request part for requesting an operation or work related to the rotational compensation when it is determined that the rotational compensation needs to be performed.

A machine tool includes: a revolving-type turret including a plurality of grips provided along a circumferential direction thereof, each of the plurality of grips being configured to hold the tool attached to a spindle; a first rotary shaft configured to rotate about a swing axis of the turret; a second rotary shaft extending in a direction substantially perpendicular to the first rotary shafts, and configured to rotate the turret about a revolving axis; a motor configured to rotate the first rotary shaft; a power transmission unit including a first gear connected to the first rotary shafts and a second gear connected to the second rotary shaft, the second gear being configured to be meshed with the first gear; and a rotation prohibition unit configured to, when swinging the turret, prohibit rotation of the second rotary shaft in order to swing the second rotary shaft about the first rotary shaft.

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.

The present invention relates to a device for the automated coupling and decoupling of a tool attachment from a tool drive means. The tool attachment and the tool drive means are configured to actuate a connection means for the connection of at least two workpieces. The connection means can be a screw or a bolt. The tool attachment can be coupled with and released from the tool drive means, in that the tool attachment is placed on the tool drive means. According to the invention, a magazine is present, having at least one tool attachment receiving space as well as holding means for the tool attachment in the tool attachment receiving space. The tool drive means is moveable in the axial direction with respect to the tool attachment for coupling as well as releasing the tool attachment with respect to the tool drive means. The tool attachment is held on the tool drive means in a form-fit manner. Coupling and decoupling occurs in an automated manner.

A machine tool, in particular a multi-spindle and/or double-spindle milling machine, comprising a machine frame, a workpiece clamping device for clamping a workpiece, an axis slide assembly which is arranged on the machine frame and is configured to linearly move the workpiece clamped on the workpiece clamping device by way of two controllable linear axes in a Y-direction and a Z-direction, and a spindle carrier assembly, which is arranged on the machine frame and has at least two tool-carrying work spindles that can be moved independently of each other in an X-direction which is perpendicular to the Y-direction and Z-direction.

A spindle includes a housing including a first opening, a bearing housed in the housing, a main shaft rotatably supported by the bearing, a collet chuck in a first through hole defined in the main shaft to grip a machining tool and being movable in an axial direction of the main shaft, a draw bar connected to the collet chuck, and a cover covering the first opening and including a second through hole through which the main shaft is disposed. The main shaft and the cover are disposed at a distance from each other.
