1. A method for creating a surface structure on a gear wheel in a honing process, comprising:
at least one honing tool is moved along the gear wheel in a first direction using a first crossed axes angle, wherein the at least one honing tool is moved along the gear wheel in a second direction, opposite to the first direction, using a second crossed axes angle, wherein the first crossed axes angle and the second crossed axes angle are chosen such that first scoring marks produced when the at least one honing tool is moved in the first direction on a surface of the gear wheel at least partially intersect, at a given angle, respective second scoring marks produced when the at least one honing tool is moved in the second direction on the surface of the gear wheel;
wherein each of the first scoring marks provided at the first crossed axes angle and the second scoring marks provided at the second crossed axes angle intersects an axis extending transversely from a center point of the gear wheel, said axis separating a left half of the gear wheel from a right half of the gear wheel;
wherein each of the first scoring marks extends from a side-left edge of the gear wheel on the left half to a top of the gear wheel on the right half; and
wherein each of the second scoring marks extends from a right edge of the gear wheel on the right half to the top of the gear wheel on the left half.
