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).
Device for the manufacture of cylindrical workpieces (1) which have a defined profiling, with an axially movable workpiece holder (2) intermittently rotatable about the longitudinal axis (Z) and forming tools (9) periodically acting on the workpiece (1), characterized in that at least one separate drive (11) mechanically separate from the drive (8) of the forming tools (9) is provided, which is connected with an electronic control which controls the intermittent rotational movement of the workpiece holder (2) in dependence of the drive (8) of the forming tools (9).
Method for the manufacture production of cylindrical workpieces (1) having a defined profiling with an axially movable workpiece holder (2) for the workpieces (1), which is intermittently rotatable about the longitudinal axis (Z), as well as forming tools (9) periodically acting on the workpiece (1), characterized in that the workpiece (1) is rotated about its longitudinal axis (Z) or stopped by way of an electronic control and a drive (11) separate from the forming tools (9) in dependence of the movement of the forming tools (9) for the generation of a predetermined defined profiling geometry on the workpiece (1).
