Abstract (en)
[origin: WO2005075125A1] The invention relates to a device for producing cylindrical workpieces (1) having defined profiled sections. The device comprises a workpiece holder (2) that is axially displaceable and intermittently rotates about a longitudinal axis (Z), and shaping tools (9; 12) that periodically act upon the workpiece. The inventive device is characterized by at least one drive (11) for the intermittent rotation of the workpiece holder (2), which is mechanically separate from the drive (8) for the shaping tools (9; 12). The drive (11) is linked with an electronic control which controls the intermittent rotational movement depending on the drive (8) of the shaping tools (9; 12). The invention allows to adjust any intermittent movement relative to the position and angle of the workpiece (1), thereby contributing to a precise and especially rapid processing of the workpiece (1).
