A grinding wheel contains two ring-shaped flanks and is axially displaceable by an axial drive. A radial slide is radially adjustably displaceable relative to the grinding wheel by a radial drive. Both of the displacements in axial and radial direction can be measured by a respective displacement path measuring device. Two dressing tools can be independently reciprocatingly displaced between an operative position and a wear measuring position at the radial slide. A wear measuring device is arranged at the radial slide for measuring in a direction extending substantially parallel to the grinding wheel axis the wear of the dressing tools. The relative displacement in the direction of the grinding wheel axis is governed by the desired flank profile, and a control increases such relative displacement in the direction of the grinding wheel axis by the amount of the wear of the dressing tools.

Profiling apparatus for a grinding wheel in a gear grinding machine

A dressing device for a substantially plate-shaped grinding wheel at a tooth flank-grinding machine for a gear comprising a dressing tool which is radially feedable by a drive means for dressing the outer or jacket surface of the grinding wheel. Measuring means serve to measure the axial feed movement of the or dished grinding wheel and the radial feed movement of the dressing tool. Control means serve to control the drive means for the radial feed movement in such a manner that its relationship to the axial feed movement of the grinding wheel corresponds to the tangent of the angle of inclination of the rear surface of the grinding wheel with respect to its lengthwise axis.
