PURPOSE:To cut a workpiece without vibration produced by a circular saw by firmly fixing a plurality of pipes with a support table having a bending member and a vertical clamp member. CONSTITUTION:A clamped pipe 1, a support table 2 and a vertical clamp 5 are brought into linear contact with one another, and also brought into contact widely extending over a circular arc a b by contact of leaf springs 10, 11. Furthermore, even if a gap delta is produced, a leaf spring 14 and the pipe 1a are brought into contact with each other within the range of a b. Therefore, notwithstanding variation of tolerance of the pipe 1 diameter, contact portions 9, 12 are always formed to clamp the pipe, so that the pipe can be kept from slipping and further from oscillating so the pipe can be cut finely. |
