Zusammenfassung:	PURPOSE:To prevent the generation of a defective work due to the unsymmetrical wear of the cutter part of a tool, by moving the tool with its reciprocation in the axial direction, while the external shape of a printed board is worked with the relative movement of the printed board and a rotating tool. CONSTITUTION:A tool 2 is moved with its reciprocation in the axial direction, while the printed board external shape is worked with the relative movement of the printed board and rotating tool 2, and the whole body of the tool 2 from its cutter part to the lower part is used in one external shape work stage from its start to its completion. Consequently, the unsymmetrical wear of the cutter part of the tool 2 is prevented with the cutter part of the tool 2 being used effectively at the exteral shape work time of the printed board, the life of the tool 2 can be prolonged, and the generation of the defective work due to the unsymmetrical wear the tool 2 cutter part can be prevented.
