1. A method for surface treatment of a workpiece, the method comprising:
providing the workpiece, the workpiece comprising a hardened workpiece surface;
providing a material removal tool and a rolling tool, the rolling tool being independently clamped relative to the material removal tool and arranged at a distance offset from the material removal tool in an axial direction of the workpiece;
clamping the workpiece;
simultaneously machining the workpiece by:
removing material from the hardened workpiece surface with the material removal tool to produce a machined surface with first machining tracks; and
rolling the machined surface with the rolling tool by overlapping the first machining tracks to produce a rolled surface with second machining tracks, wherein the distance between the material removal tool and the rolling tool measured in the axial direction of the workpiece is varied in an oscillating manner.
