A machine tool for the machining of elongate workpieces includes a workpiece support column having workpiece support components for supporting a first workpiece and second workpiece support components for supporting a second workpiece. The first workpiece support component and the second workpiece support component are arranged for supporting the first workpiece vertically above the second workpiece. The workpiece support column is rotatable around a vertical axis so as to shift the workpieces between the machining station and a station for loading and unloading of workpieces. The workpiece support component include a drive element for applying torque to the workpieces for machining of the workpieces by turning. A motor and chuck assembly and a method of machining workpieces are related.

A transfer machine for cold plastic deformation and/or chip removal of at least one tubular profile is provided. The transfer machine has a base, a mounting table, a rotary table, and a plurality of electromechanical work units installed on the mounting table. Each electromechanical work unit has a first advance group having a first advance motor, a first advance recirculating ball screw, a first advance nut and a first tubular stem. The first advance recirculating ball screw is moved by the first advance motor. The first advance nut is engaged by the first advance recirculating ball screw. The first tubular stem, defining advancement and/or positioning of a first tool holder element, is engaged to and made integral with the first advance nut.

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.

The present invention relates to a machine tool (1000) for machining a workpiece (1), comprising: at least one first machine tool structure which can be moved freely on a base surface and has at least one machine tool component, and at least one second machine tool structure having at least one further machine tool component, wherein the at least one freely movable first machine tool structure, together with the at least one second machine tool structure, forms the machine tool (1000) configured for machining the workpiece (1), when the at least one freely movable first machine tool structure is positioned on the at least one second machine tool structure.

Methods and systems are provided for mass producing different products in an automated production station having a plurality of part-processing devices. An example method includes identifying a workpiece received in the production station; selecting control parameters associated with the identified workpiece; electronically synchronizing the part-processing devices based on the selected control parameters to perform coordinated operations on the workpiece for producing one of the different products; and automatically repeating the identifying, selecting, and synchronizing steps for different workpieces received in the production station to produce a plurality of different products in a continuous mass production process.

The machine tool has a machine bed having a first horizontal linear guide and a second horizontal linear guide arranged at right angles to the first linear guide. On the first linear guide is arranged, in an axially displaceable manner, a workpiece clamping fixture, which is swivelable about a swivel axis oriented parallel to the second linear guide and is rotatable about a rotation axis oriented at right angles to the swivel axis. On the second linear guide a toque motor driven swivel arm is axially displaceable, the swivel axis of which is arranged parallel to the first linear guide and which on its free end bears a tool spindle, the axis of which is oriented parallel to the first linear guide.

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.
