The deburring tool (20) includes: upper and lower ball holding members (42, 52) disposed so as to oppose each other; upper and lower balls (43, 53) that are rotatably supported by the respective upper and lower ball holding members (42 52) and that project so as to confront opposing surfaces of the respective lower and upper ball holding members (52, 42). In a state where a thermally cut portion (A) of the sheet material (W) is held between the upper and lower balls (43, 53), by moving the sheet material (W) along the thermally cut portion (A) by a sheet material moving mechanism, a lower surface edge portion (C) along the thermally cut portion (A) of the sheet material (W) is pressed upward by the lower ball (53). |
