Grinding machine, and method for machining a feathered edge of a rotor blade

A grinding machine for machining a feathered edge of a rotor blade, comprising:

• a grinding unit with a driven grinding tool;
• a workpiece mounting device, which is adapted for mounting of a rotor blade to be ground;
• and
• a workpiece drive unit which is designed for moving the workpiece mounting device, together with a rotor blade mounted on the workpiece mounting device, relative to the driven grinding tool for the purpose of metal-removing machining of a feathered edge of the rotor blade mounted on the workpiece mounting device;
• wherein the workpiece drive unit has a pivot axis on which the workpiece mounting device is retained in such a way that the feathered edge of the rotor blade mounted on the workpiece mounting device is brought into engagement with the grinding tool in the course of a pivoting movement of the workpiece mounting device around the pivot axis, and
• a pivoting device on which the grinding unit is pivotably mounted for adjusting a longitudinal axis of the driven grinding tool with regard to a longitudinal-axis basic position.
