Method for hard fine machining of the toothing of a gear or of a gear-like profile of a workpiece

A method for hard fine machining of the toothing of a gear or of a gear-like profile of a workpiece, wherein the gear or the workpiece has an axis of rotation, wherein at the method the toothing of the gear or the gear-like profile of the workpiece is machined with a hard fine machining tool, wherein the hard fine machining tool has an axis of rotation and rotates around the same during hard fine machining, wherein the method comprises the steps:

• a) providing a hard fine machining tool which comprises at least two axially adjacent machining zones, wherein a first machining zone is designed for the grinding of the toothing of the gear or of the gear-like profile of the workpiece and wherein a second machining zone is designed for the fine grinding or polishing of the toothing or of the gear-like profile, wherein a profile of the hard fine machining tool in the first machining tool is identical to a profile of the hard fine machining tool in the second machining zone;
• b) grinding the toothing of the gear or of the gear-like profile of the workpiece with the first machining zone of the hard fine machining tool, wherein between the axis of rotation of the gear or of the workpiece and the axis of rotation of the hard fine machining tool a first pivoting angle is existent;
• c) fine grinding or polishing the toothing of the gear or of the gear-like profile of the workpiece with the second machining zone of the hard fine machining tool, wherein between the axis of rotation of the gear or of the workpiece and the axis of rotation of the hard fine machining tool a second pivoting angle is existent, which is different from the first pivoting angle.
