Abstract

A processing device for processing a material with a focused blasting medium, having at least a blasting medium source for generating the blasting medium and a conveying device for the material, or additionally a deflecting means for deflecting the blasting medium emitted by the blasting medium source toward the material; wherein the conveying device is arranged opposite the blasting medium source or the deflecting means in such a way that the material, at least with a region to be processed by the blasting medium, can be processed by the conveying device on a circular path opposite the blasting medium source or the deflecting means, so that the material, when the blasting medium source or the deflecting means is moved, can be processed along the circular path with a constant focus position of the blasting medium. A method for processing a material with a focused blasting medium in a processing device.

First claim

1 . A processing device for processing a material with a focused blasting medium, comprising:
a blasting medium source for generating the blasting medium, and a conveying device for the material, or additionally a deflecting means for deflecting the blasting medium emitted by the blasting medium source toward the material; wherein the conveying device is arranged opposite the blasting medium source or the deflecting means in such a way that the material, at least with a region to be processed by the blasting medium, can be processed by the conveying device on a circular path opposite to the blasting medium source or to the deflecting means, so that the material, when the blasting medium source or the deflecting means is moved, can be processed along the circular path with a constant focus position of the blasting medium.

2 . The processing device according to claim 1 , wherein the material is configured to be moved by the conveying device along a conveying direction relative to the blasting medium source or the deflecting means.

3 . The processing device according to claim 2 , wherein the conveying direction runs along the circular path or transversely to the course of the circular path.

4 . The processing device according to claim 1 , wherein, through a movement of the blasting medium source or of the deflecting means, the focus position of the blasting medium is movable at least along the circular path and additionally transversely to the course of the circular path\.

5 . The processing device according to claim 1 , wherein the blasting medium is a laser beam.

6 . The processing device according to claim 1 ,
wherein the processing device comprises the deflecting means, and wherein the deflecting means has a pyramid shape.

7 . A method for processing a material with a focused blasting medium in a processing device which has at least one blasting medium source for generating the blasting medium and a conveying device for the material, or additionally comprises a deflecting means for deflecting the blasting medium emitted by the blasting medium source toward the material; wherein the conveying device is arranged opposite the blasting medium source or the deflecting means so that the material, at least with a region to be processed by the blasting medium, is arranged by the conveying device on a circular path opposite the blasting medium source or the deflecting means; wherein the method comprises at least the following steps:
a) placing the material in the conveying device; and b) processing of the material with the blasting medium, wherein the material is processed along the circular path with a constant focus position of the blasting medium.

8 . The method according to claim 6 , wherein the material is configured to be moved by the conveying device relative to the blasting medium along the circular path or transversely thereto at least during step b).

9 . The method according to claim 7 , wherein, during step b), the focus position of the blasting medium is moved by a movement of the blasting medium source or of the deflecting means at least along the circular path and additionally transversely to the course of the circular path.

10 . The method according to claim 7 ,
wherein the processing device comprises the deflecting means, wherein the deflecting means has a pyramid shape, wherein, during step b), by rotation of the deflecting means, the focus position of the blasting medium is moved at least along the circular path, and wherein a speed of the focus position is greater than a feed speed of the material in the conveying device as a result of a rotational speed of the deflecting means.
