Abstract. The currently existing methods of production ball-rolling rolls, taking into account the capabilities of metal-cutting equipment presented. The prospects development of methods for roll-pass design ball-rolling rolls with the possibility of obtaining any form parts of complexity on the projected 3-D models on 4 or 5-axis machining centers have been determined. Developed the model for calculating ball-rolling rolls with variable depth of channel. Presented are promising possible ways to production ball-rolling rolls with roll-pass designs developed by this method and with variable depth of channel, which will allow to obtain a high accuracy degree of the resulting ball, including geometry quality, uniformity of compression between equators and poles.
Keywords: ball-rolling roll, variable depth of channel, 5-axis machining centers, longitudinal feed, circular feed.
