<p>PROBLEM TO BE SOLVED: To correct a shaft by a proper correction amount, while improving efficiency in correction work, by shortening correction process time, by simplifying arithmetic processing of a target value of a moving distance of a correction tool.SOLUTION: A strain correction machine comprises: a strain measurement device (7) for measuring a strain amount in a predetermined place of a shaft (6); a correction device (9) for correcting the shaft (6) by further moving a correction tool (29) contacted with the shaft (6) to the shaft (6) side; and an arithmetic operation device for arithmetically operating a target value of a moving distance of the correction tool (29) based on the strain amount measured by the strain measurement device (7), in which the arithmetic operation device is constituted for arithmetically operating the target value by adding a fixed value set regardless of the strain amount to a strain amount corresponding value calculated in accordance with the strain amount.</p> |
