MOLDING MACHINE FOR ROTARY EXTRUSION/ROLLING AND METHOD OF ROTARY EXTRUSION/ROLLING

摘要

The invention relates to a forming machine for the spinning/flow forming of a workpiece, having a machine bed, a headstock, a main spindle rotatably mounted on the headstock, having a flow forming mandrel, which is provided to receive the workpiece, a support, which carries at least one machining tool, and which is axially displaceable relative to the main spindle in a longitudinal direction of the machine bed. Furthermore a main spindle drive for driving the main spindle in rotation and a feed drive for displacing the support are provided. The main spindle drive has at least two drive motors, each having a drive pinion. The main spindle has a driving gear, which can be driven by the drive pinions of the drive motors.
