Abstract

Spinning lathe (100) comprises an upper support (40), a lower support (50) and an additional auxiliary support (30) aligned on the upper support. A pressure roller holder (20) and pressure roller (22) are mounted on the auxiliary support. The auxiliary support is connected to the upper support by a piston-cylinder arrangement (32) with a path sensor (34) for measurement of their relative position and delivery of a corresponding signal to a control unit. Thus over-determination of the system is prevented. The control unit for the X-coordinate continuously receives the current position of the print roll, even when this is pushed slightly within the auxiliary support. Thus the auxiliary support can be used to regulate the deformation force on the print roll at every position on the workpiece (1). The invention also relates to a corresponding method for smoothing or polishing the surface of a workpiece with a spinning lathe.
