PURPOSE: A bending correcting device is provided to correct a bent circular saw through a comparatively simple process. CONSTITUTION: A circular saw(100) bent on the center of a circular plate(110) is supported by a hanger like a crane(310). A circular saw transferring device enables the circular saw to move up and down and to rotate. A frame(210) is symmetrically established on both sides. A pair of blocks(220) is formed on right and left inner sides of the frame and has uneven shape structure. A pair of rollers(230) established on the lower sides of the blocks is rotated by a rotating unit. A hydraulic cylinder(240) formed on the blocks and rollers move the blocks and rollers to the center side of the frame by the hydraulic press. The blocks pressed to both sides of the circular plate by the hydraulic pressure perform a press processing. The rollers provide pressurization to both sides of the circular plate. Thus, a pressurization processing is performed on a partly bent portion with a rolling working.
