Method for grinding a toothing or a profile of a workpiece

A method for grinding a toothing or a profile of a workpiece by a grinding wheel, wherein the grinding wheel is designed as a profile grinding wheel and is guided through pre-machined tooth or profile gaps or produces tooth or profile gaps, wherein the workpiece has an axis of rotation, wherein the grinding wheel has an axis of rotation and a center which lies on the axis of rotation of the grinding wheel and in the middle of the axial extension of the grinding wheel, and wherein the workpiece has an end face at least in one axial end region of the toothing or of the profile, wherein the grinding the toothing or the profile comprises the steps:

• a) profile grinding the toothing of the workpiece using the profile grinding wheel, wherein the profile grinding wheel is guided through the pre-machined tooth or profile gaps or produces the tooth or profile gaps;
• b) grinding of chamfers in the one axial end region of the tooth or profile gaps by means of the grinding wheel, wherein the grinding wheel is arranged in a position, or at least temporarily assumes a position during the grinding of the chamfers, in which the grinding wheel is arranged relative to the workpiece in such a way that an axial end of the tooth or profile gap contacts the grinding wheel, wherein in a projection on a plane including the axis of rotation of the workpiece as well as the center of the grinding wheel an angle between 20° and 70° is included between the axis of rotation of the workpiece and a connecting line between the center and the axial end contacting the grinding wheel,
• wherein the profile grinding wheel is a dressable grinding wheel and that after carrying out step a) and before carrying out step b) the profile of the grinding wheel is changed by a dressing operation.
