  • the pressing belt 370 is therefore not directly in the working position on the back of the finishing tape, but is supported by the pressing elements on the back, which in turn press the finishing tape at defined predetermined and offset in the circumferential direction zones on the peripheral surface of the workpiece section. Since the pressure elements press only in spatially limited areas on the finishing belt, larger surface pressures can be generated in these areas with the same external contact pressure F as in large-scale investment of a pressing belt. In addition, a more constant surface pressure is often possible. Furthermore, the supply of cooling lubricant and the chip removal are facilitated.

  • the radius of curvature of the pressing belt 410 is also reduced, so that smaller diameter workpiece sections can be machined over a large area. If a workpiece section with a larger diameter is then to be machined, the clear distance between the fixed bearing points 472, 473 is increased with the aid of the adjusting device 410, so that the pressure band reduces its curvature in the sense of extension and a larger radius of curvature is set, which corresponds to the larger workpiece diameter is adjusted.
