A device for finishing cylindrical workpieces is described, having an arrangement for rotating the workpiece, two retaining arms, each having a support and a pressure cheek received in it, wherein at least one pressure cheek is floatingly seated on the associated support, and the pressure cheeks at least partially envelop the workpiece, a grinding belt, and belt guidance means guiding the grinding belt in such a way that it at least partially envelops the workpiece and is pressed against the workpiece by the pressure cheeks, as well as an arrangement which puts the retaining arms into a back-and-forth movement parallel with the axis of rotation (A) of the workpiece. Here, either the support or the pressure cheek have a lining of a plastic material, which slightly extends in a T-shape past the lateral walls of the quick-change adapter, and which can at least slightly be compressed elastically. The other component of the pair of support/pressure cheeks is embodied U-shaped in cross section and extends over the lining of the first mentioned component.
