Method for hard fine machining of a workpiece with a worm-shaped cutting tool

A method for hard fine machining of a workpiece with a worm-shaped cutting tool, wherein the workpiece comprises an axis and with a profiling along its circumference, wherein the cutting tool comprises an axis and a machining surface, the method comprising the steps of:

• carrying out a hard machining process of the profiling with simultaneous synchronized rotation of the workpiece around its axis and of the cutting tool around its axis with given meshing of the machining surface into the profiling by moving the cutting tool in a direction of the axis of the cutting tool;
• and
• superposing a shift movement to the cutting tool in a direction of the axis of the cutting tool during the hard machining process, wherein
• the shift movement includes at least one first section in which the cutting tool is moved in one of the directions of its axis and includes at least one second section in which the cutting tool is moved in the other of direction of its axis.
