A rolling mill system for Incremental rotary shaping of an elongated workpiece is provided that includes first and second workpiece holders. A support frame has a track with the first and second workpiece holders being movably associated with the track, the workpiece holders and an associated workpiece being movable in unison along the track. A radial chuck is mounted to the frame that includes a plurality of jaws that are movable radially inwardly and outwardly. Each jaw has a tool mounted thereto that is rotatable about an axis of rotation, with the axis of rotation of each tool being oriented at a skew angle relative to the longitudinal axis of a workpiece. A source of electric current and an electrically conductive flow path are provided for flowing electrical current through a workpiece. A controller is provided that is configured to control the operation of each of the first motor, second motor and third motor, and to control the flow of current flowing through the tools to the workpiece.

Rolling station intended to couple with a respective rolling cartridge or stand provided with two rolling cylinders, wherein the rolling station has a supporting frame of the transmissions suitable for housing a pair of transmission devices of which a first transmission device is intended to couple with a first rolling cylinder and a second transmission device is intended to couple with a second rolling cylinder, the first rolling cylinder being put in rotation by a first motor via the first transmission device and the second rolling cylinder being put in rotation by a second motor via the second transmission device.

A pilger rolling mill with a roll stand moves linearly back and forth along a movement direction and includes a crank mechanism having a rotatably supported crankshaft with a crank pin and push rod. A first end of the push rod is pivotably fastened to the crank pin and a second end is pivotably fastened to the roll stand, so that during operation of the pilger rolling mill a rotary movement of the crankshaft is converted into an oscillating movement of the roll stand along the movement direction. A compensation shaft is rotatably supported about an axis of rotation and includes a distribution of mass that is not rotationally symmetrical relative to its axis of rotation and a counter-mass. The crankshaft and the compensation shaft are connected to one another by a transmission so that a rotation of the crankshaft leads to a rotation of the compensation shaft.

A hand-powered jewellery rolling mill is disclosed. The mill comprises a support frame and a pair of opposed parallel cylindrical rollers rotatably mounted to the support frame. A drive shaft is connected to at least one of the rollers for rotation thereof. A manually rotatable handle is configured for providing a drive force to the drive shaft. The handle may be connected to the drive shaft through a high-ratio gear train. The rolling mill may further comprise an input shaft, rotatable by the manually rotatable handle. The input shaft may have a worm and a worm-to-gear coupling may transfer torque from the input shaft to the drive shaft.
