Abstract
A belt-finishing device including a frame. A pressing arm is configured to pivotally mount on the frame. A pressing element, which is used to press a finishing belt against a workpiece surface to be treated, is arranged on the pressing arm. The device is provided with a position detection system for detecting a pressing-arm actual position that deviates from a desired position of the pressing arm. A malfunction or defect of the pressing element is detected by means of the pressing arm actual position that deviates from the desired position of the pressing arm.
Claims13
A belt finishing device comprising:
- a frame;
- a pressing arm mounted to the frame;
- a pressing element arranged on the pressing arm;
- a finishing belt disposed on the pressing element and configured to press against a workpiece surface to be treated;
- and
- a position detection apparatus configured to detect an actual position of the pressing arm that deviates from a desired position of the pressing arm.
