Method for producing and mounting a body having an angle scaling
A method for producing and mounting a body having an angle scaling includes: applying three markings to the body, the markings being set apart from each other; adjusting the body relative to a support device, so that the distances between the markings and a point, which is permanent relative to the support device, are equal; applying an angle scaling to the adjusted body; dismounting the body from the support device; and mounting the body, provided with the angle scaling, on a machine part so that the distances between the markings and a point, which is permanent relative to the machine part, are equal.
1. A method for producing and mounting a body having an angle scaling, comprising:
applying at least three markings on the body, the markings set apart from each other in a circumferential direction of the body;
adjusting the body relative to a support device so that distances between the markings and a point, which is permanent relative to the support device and which is located on an axis of rotation of the support device, are equal;
applying an angle scaling to the body after the adjusting step;
after the angle scaling applying step, dismounting the body, provided with the angle scaling, from the support device; and
mounting the body, provided with the angle scaling, on a machine part so that distances between the markings and a point, which is permanent relative to the machine part and which is located on an axis of rotation of the machine part, are equal.
2. The method according to claim 1 , wherein the angle scaling is applied in the angle scaling applying step by an ablation process.
3. The method according to claim 1 , wherein the markings are applied in the markings applying step by an ablation process.
4. The method according to claim 1 , wherein the markings are applied in the markings applying step by a laser ablation process.
5. The method according to claim 1 , further comprising coating the body at least in a region of the angle scaling after the angle scaling applying step.
6. The method according to claim 1 , further comprising coating the body at least in a region of the markings after the markings applying step.
7. The method according to claim 1 , further comprising coating the body with an ablation layer at least in a region of the markings after the markings applying step.
8. The method according to claim 1 , wherein the markings include three markings arranged offset from each other by 120° in the circumferential direction of the body.
9. The method according to claim 1 , wherein the body has a ring shape.
10. The method according to claim 9 , wherein a ratio of an outside diameter of the body to an inside diameter of the body is less than 5.
11. The method according to claim 1 , wherein the angle scaling is applied in the angle scaling applying step on a lateral side of the body.
12. The method according to claim 11 , wherein the body has a circularity deviation in a region of the angle scaling less than 100 μm.
13. The method according to claim 11 , wherein the body has a circularity deviation in a region of the angle scaling less than 50 μm.
14. The method according to claim 1 , wherein the angle scaling is applied in the angle scaling applying step by a laser ablation process.
15. The method according to claim 1 , wherein the angle scaling is applied in the angle scaling applying step by lithography.
16. The method according to claim 1 , wherein the markings are applied in the markings applying step by lithography.
