To reduce unbalance in thin-walled hollow shafts without local material removal, a dynamic balancing method based on machining datum-axis correction is proposed. The method adjusts the left- and right-end machining datums during outer cylindrical finishing, causing the generated outer cylindrical axis to translate and tilt relative to the original datum axis. The existing machining allowance is thus redistributed continuously in the circumferential and axial directions, producing an equivalent compensating unbalance through the shifted centroid of the removed layer. The geometric relationship among datum correction, sectional correction vectors, and depth-of-cut variation is established. A compensation model for static and couple unbalances is derived for a constant-diameter shaft and extended to a stepped hollow shaft by considering the contributions of segment radius, length, and axial position. A Timoshenko-beam finite element model is then used to evaluate the effects of correction magnitude and direction angle on residual unbalance and synchronous vibration. The results show that correction magnitude mainly controls compensation amplitude, whereas direction angle determines compensation orientation. For the selected correction combination, continuous increased and decreased depth-of-cut regions are formed on the outer surface. At 10,000 r\/min, the left and right synchronous vibration amplitudes decrease by 77.50% and 75.52%, respectively; reductions are also observed at 15,000 and 20,000 r\/min.<\/p>\n\n\n\n
