Abstract: PURPOSE:To enable the correction with a minimum repeat of correction at the time of measuring the rotation unbalance quantity of a target of a rotary anode type X-ray tube to compute the correction data on the basis of the measurement data by measuring the abrasion condition of a cutting tool previously to reflect it on the correction quantity of a target and correct the rotation unbalance. CONSTITUTION:A target 21 is set in an unbalance measurer, and rotated at a high speed, and an angle of rotation and the unbalance weight from the reference position are measured to obtain the unbalance quantity. The measured target 21 is positioned and fixed at a predetermined position by a chuck 32, a holding claw 33 of an unbalance correcting machine. On the other hand, the measurement data is converted to the correction data D1, which consists of cutting depth and cutting length of a rotary bar 35, by a correction data computer. The correction data D1 of the first time is output to an unbalance correcting machine. The correction data D2 is output as the correction data [D1/(D1-D2)]D2 to the unbalance correcting machine. As a result, unbalance of the target 21 is corrected accurately, and the following correction is not necessary.
