Abstract: The invention relates to a method for machining toothings, which method uses a disk-shaped, toothed tool that is rotationally driven about its axis of rotation and has a geometrically defined cutting edge. The tool teeth are produced from a base material, are provided, at least on the tooth flanks, with a coating that improves wear resistance, and have machining surfaces facing an end face of the tool, said machining surfaces being re-ground from time to time when the tool is reconditioned, wherein after at least one regrinding, use of the tool is resumed and continued with regions of the machining surfaces formed along the cutting edges from the base material.

In a first work operation a grinding zone of a grinding tool whose selection is determined by the grinding process to be performed, which rotates about an axis of rotation and is set up for an infeed in the direction of the shortest distance between said central axis and the rotation axis, is brought into grinding engagement with a tooth flank of the workpiece. In a later, second work operation, the tooth flank is brought into grinding engagement with a grinding zone of a grinding tool whose selection is determined by the grinding process to be performed and which is advanced in the infeed direction of the first operation.
