Abstract
A pressure shoe (1) includes a press surface (2) for directly pressing finishing tape onto a radial circumferential surface (3) of a rotating workpiece section (4) during a finishing process. A plurality of expansion elements (5) is formed in the pressure shoe (1). Each of expansion elements (5) are expandable individually and independently of one another radially while deforming the press surface (2) in a direction of the circumferential surface (3) of the workpiece section (4), so that during the finishing process, the shape of the circumferential surface (3) of the workpiece section can be influenced in a targeted manner via different expansion of the expansion elements (5) distributed over the press surface (2).

A pressure shoe (1), comprising:
- a press surface (2) for directly pressing finishing tape onto a radial circumferential surface (3) of a rotating workpiece section (4) during a finishing process;
- a plurality of expansion elements (5) being formed in the pressure shoe (1), wherein each of the plurality of expansion elements (5) are expandable individually and independently of one another radially while deforming the press surface (2) in a direction of the circumferential surface (3) of the workpiece section (4), so that during the finishing process, the shape of the circumferential surface (3) of the workpiece section can be influenced in a targeted manner by different expansion of the expansion elements (5) distributed over the press surface (2), wherein each expansion element is formed by a respective expansion chamber (5), wherein each expansion chamber (5) is connected individually to a line (6) leading out of the pressure shoe (1) and is expandable radially under pressurization of the fluid while deforming the press surface (2) in a direction of the circumferential surface (3) of the workpiece section (4).
A method for operating a finishing device with a pressure shoe (1), comprising at least the following steps:
- providing a pressure shoe (1), comprising:
- a press surface (2) for directly pressing finishing tape onto a radial circumferential surface (3) of a rotating workpiece section (4) during a finishing process;
- a plurality of expansion elements (5) being formed in the pressure shoe (1), wherein each of the plurality of expansion elements (5) are expandable individually and independently of one another radially while deforming the press surface (2) in a direction of the circumferential surface (3) of the workpiece section (4), so that during the finishing process, the shape of the circumferential surface (3) of the workpiece section can be influenced in a targeted manner by different expansion of the expansion elements (5) distributed over the press surface (2), wherein each expansion element is formed by a respective expansion chamber (5), wherein each expansion chamber (5) is connected individually to a line (6) leading out of the pressure shoe (1) and is expandable radially under pressurization of the fluid while deforming the press surface (2) in a direction of the circumferential surface (3) of the workpiece section (4);
- pressing a finishing tape onto the radial circumferential surface (3) of the workpiece section (4) to be processed, using the pressure shoe (1);
- and
- expanding at least one of the plurality of expansion elements (5), so that the expansion element (5) deforms the press surface (2) in a radial direction.
