The entire operable system of the device is supported on a fixed frame which in turn is mounted for partial rotation with respect to an overall support in two different planes so as to respectively vertically and laterally position the driven wheel with respect to objects to be finished, e.g., sanded or polished, at a work station. In addition, the drive system for the driving wheel is entirely carried by a pivotal plate which is in turn attached to the frame at the rear thereof. The drive system including means for continually tensioning the belt and for releasing such tension by partially rotating such pivotal plate.
