A profiling roller for producing a profile on a grinding wheel used in a thread grinding machine operating with longitudinal feed (along the axis of the rotating wheel) having a central finishing roller rib of size and configuration corresponding to the thread to be produced, said finishing rib being flanked with preliminary roller ribs of progressively decreasing height and width and arranged symmetrically with respect to the finishing rib toward the ends of the roller. The dimensions of the progressively smaller ribs compared with the finishing rib are geometrically defined in the specification in terms of root radii, flank angle and pitch circle radii.
