PURPOSE: A method and device for correcting an adaptive PID control-based shaft is provided to maintain the productivity of correcting work regardless of a change in the strength of a shaft depending on seasons, since it is possible to PID control considering a change in the temperature of seasons. CONSTITUTION: A method and device for correcting an adaptive PID control-based shaft comprises next steps. A level of deformation is measured when a shaft is pressed by given load, so the strength of the shaft is obtained. When the shaft is pressed and corrected by press through PID control, the strength of the shaft is applied as a weighted value and the pressure time of the shaft by the press is controlled depending on the strength of the shaft. The strength of the shaft is obtained by pressing the shaft with the press and measuring the level of deformation of the shaft with a displacement sensor.
