Title: Polishing method of work-piece and polishing device
Inventor: INOUE YUKI
IPC: B23K26/03
Filed: 2021-02-19
Abstract: To provide a polishing method of a work-piece and a polishing device in which a work-piece with a polished surface that has in-surface uniformity of irregular (asymmetric) thickness can be polished to be a prescribed finished shape (for example, flat plate shape) in a high accuracy.SOLUTION: A polishing method is given in which: before polishing a work-piece, stronger laser beam is irradiated to a region of the work-piece, the more there is a less difference between a prescribed finished shape (for example, flat plate shape) and the region. For example, the laser beam is irradiated to a region (former region) where the difference is small between the prescribed finished shape and the region, on the other hand, the laser beam is not irradiated to a region (latter region) where the difference is large between the prescribed finished shape and the region. In this case, the former region is largely changed in quality in comparison with the latter region. Specifically, material of the former region is oxidized, or crystal structure thereof is broken. And then while supplying the surface of the work-piece to which laser beam is irradiated with alkaline fluid, the work-piece is polished.SELECTED DRAWING: Figure 8
