Abstract

The axis of the shaft on which the guide roller is mounted can be adjusted so it is always in the same position w.r.t. the periphery of the grinding wheel. The result is automatic compensation for the wear of the grinding wheel and cam profiles with high dimensional accuracy. The shaft carrying the blank and master profile is located on a sliding table and a diamond continuously and automatically trues the periphery of the wheel. The cam discs are for automatic program-control devices. A traverse on the moving table is used to hold the vertical shaft on which the guide roller is mounted and the master is pressed against roller by a spring. A diamond oscillates in a horizontal plane so that a convex surface is obtd. on the rim of the grinding wheel, having a radius the same as the radius of the guide roller.
