The processing apparatus 1 according to the embodiment and the embodiment also processes a convex portion B of a groove G other than the horizontal, such as an inclined or vertical groove G. Of course, as described above, the processing apparatus 1 according to the embodiment and the embodiment is not limited to the one groove G, but may be formed in each groove in a different direction from the state of being fixed to the groove G (described later). A certain convex portion B is processed. When these two different directions are 180 ° and these two grooves G are connected, the groove G becomes one row.

Further, although the processing apparatus 1 according to the embodiment and the embodiment has been described as processing (cutting) the convex portion B, it does not mean that only the convex portion B is processed (cut), but the convex portion. The circumference of B may also be machined (cut).

In addition, the convex portion B according to the embodiment shows the weld bead B in FIG. 1 as an example, but it may be a portion that is raised more than the others, and is, for example, an unprocessed portion in the groove G.

Further, the embodiments and examples are exemplary in all respects and are not limiting. The scope of the present invention is shown by the scope of claims rather than the above description, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.
