The present invention concerns a pilger rolling mill comprising a roll stand (1), a flywheel (10) on a drive shaft which is mounted rotatably about an axis of rotation (18), and a thrust rod (6) having a first end (16) and a second end (17), wherein the first end (16) of the thrust rod (6) is fixed to the flywheel (10) at a radial spacing (7) from the axis of rotation (18) and wherein the second end (17) of the thrust rod (6) is fixed to the roll stand (1) so that in operation of the mill a rotary movement of the flywheel (10) is converted into a translatory movement of the roll stand (1), comprising a drive motor (9) having a motor shaft (8a), wherein the motor shaft (8a) of the drive motor (9) and the drive shaft (8b) are connected together in such a way that a rotary movement of the motor shaft (8a) leads to a rotary movement of the drive shaft (8b) and thus the drive motor (9) drives the flywheel (10). To provide a pilger rolling mill whose drive for the roll stand exhibits no or only very little wear and which in addition permits a precise displacement of the roll stand with a high degree of repetition accuracy, according to the invention it is proposed that that the drive motor (9) is a torque motor.
