MACHINED MATERIAL FIXING JIG, LASER PROCESSING DEVICE, AND METHOD OF MANUFACTURING SLEEVE PRINTING PLATE

摘要

PROBLEM TO BE SOLVED: To provide a machined material fixing jig capable of preventing the machined material fixing jig from being damaged and allowing to perform highly accurate laser processing even in irradiating a machined material with laser beams for through machining performed through it in a thickness direction, a laser beam machining device equipped with the same and a method of manufacturing a sleeve printing plate.

SOLUTION: The machined material fixing jig 10 supports the machined material when performing laser processing on the machined material. The machined material includes a part to be subjected to through machining that it is machined through it in the thickness direction by the laser processing. A recessed part 15 is formed in a support face 11 for supporting the machined material at a position corresponding to the part to be subjected to through machining of the machined material.
