PURPOSE: A repairing method of a circular saw is provided to recycle the circular saw by repairing the saw of which disc is curved. CONSTITUTION: A curved disc is supported on a hanger frame of appropriate height(S1). The disc is descended while rotated at a specific speed(S2). The disc is pressurized by blocks of mutually corresponding structure with the hydraulic pressure from right and left sides(S3). The curved disc is corrected through a rolling work with the hydraulic pressure from the right and left sides(S4). When the flatness of the disc is over a specific size, the process is circulated to the first step(S5). Accordingly, cost of components is saved by correcting the curved disc through a press process and a rolling process.
