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).

The invention relates to a transport device comprising a rotary object carrier which comprises object carrier elements arranged so as to be distributed around the circumference, on which carrier elements objects are arranged which are transported on a circular movement path from work station to work station of a production facility. Furthermore, the invention relates to a production facility for making products, in particular containers filled with a medical product, comprising a transport device of this kind, as well as to a method for transporting objects from work station to work station of a production facility. The transport device according to the invention is characterised in that one or more actuator units 18.1, 18.2; 12.1, 12.2 are assigned to one object carrier element 6 or to a plurality of object carrier elements 6, which units can move together with the object carrier element 6 or the object carrier elements 6. Since the actuator units 18.1, 18.2; 12.1, 12.2 rotate together with the object carrier elements, process steps can be performed on the objects that are assigned to the object carrier elements directly on the object carrier elements. A stationary arrangement of actuators that engage with the objects from the outside is therefore not required. This makes the entire production process more flexible. The actuator units are preferably provided with media by a central supply device by means of a rotary feedthrough.

The invention relates to a rotary feedthrough for a transport device comprising a rotary object carrier 3 which comprises object carrier elements 6 arranged so as to be distributed around the circumference, on which carrier elements objects are placed which are transported on a circular movement path from work station to work station of a production facility. Furthermore, the invention relates to a transport device comprising such a rotary feedthrough, and to a production facility for making products as well as to a method for transporting objects from work station to work station of a production facility. The rotary feedthrough according to the invention comprises a stationary component 19 having one or more media inputs 20.1, 20.2, 20.3 for providing one or more media for supplying one or more actuator units 12.1, 12.2; 18.1, 18.2 of an object carrier element 6.1, 6.2. Furthermore, the rotary feedthrough comprises a plurality of components 24.1, 24.2, 24.3, 24.4 which are rotatable independently of one another about a common central axis 23 relative to the stationary component 19 and which each comprise one or more media outputs 25.1, 25.2. The rotary feedthrough permits the formation of a media connection between actuator units assigned to object carrier elements 6, which actuator units can be moved on a circular movement path on an object carrier 3 or can remain on the object carrier in a fixed location, and a fixed, central supply device 21.

The present disclosure includes a part hold-down assembly for retaining an oversized part. The part hold-down assembly is aligned along a central force axis and applies a downward force onto the part. The part-hold down assembly includes a top plate, a bottom plate, and a compression assembly extending between the top and bottom plates. The compression assembly includes two, parallel biasing assemblies that extend along compression axes that are parallel to but offset from the central force axis. Each biasing assembly including an upper collar, a lower collar and a resilient biasing member, in one embodiment in the form of a coil spring, retained between the upper and lower collar. The parallel biasing assemblies are positioned on opposite sides from each other about the central force axis, and may be spaced away from the central force axis an equal distance.

A machine for machining workpieces includes a movably mounted table (1) and at least one clamp (2). Each clamp is engageable with a workpiece and can be rotatably driven relative to the table. Each workpiece is transportable by movement of the table to a first workstation (3). Workstation 3 includes a toolholder (4) that holds a tool that is operative to machine a surface of the workpiece. The toolholder is movable in engagement with the workpiece by a feed unit (5) and the orientation of the tool holder relative to the workpiece is changeable by movement of an alignment unit (6). A second workstation to which the workpiece is moved after machining includes a cleaning device (8). A third workstation to which the workpiece is moved after cleaning includes a measuring device (10) that optically determines at least one surface property of the machined surface. The measuring device is in connection with an evaluation unit (14). The evaluation unit evaluates the at least one surface property and determines a direction and an order of magnitude that the alignment unit must be adjusted so at least one subsequently machined workpiece meets required tolerance specifications.

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.

The invention relates to a device and a method for welding blades, in particular in order to produce a cutting unit for a wet razor.
