DEVICE AND METHOD FOR ELECTROMECHANICALLY-ASSISTED ROLLER BURNISHING

摘要

The invention relates to a device and method for electromechanically roller burnishing a surface of a workpiece, in which precisely one current-guiding roller burnishing element for roller burnishing and one separate electrical contact element are used and, as the roller burnishing element is moved on the workpiece surface, said electrical contact element is guided thereafter such that a current path of a constant length is directed through the workpiece as roller burnishing takes place. The invention allows, in a cost-effective manner, a high surface quality to be achieved as well as a precisely-adjustable microstructural alteration to the upper layers of the workpiece.

主权项

1. A device for electromechanically assisted roller burnishing (EMRB),
wherein a roller burnishing tool with exactly one current-leading roller burnishing element is given for burnishing a workpiece, and this roller burnishing element represents a first electrical contact element for the electrical contacting on a first location of the workpiece, and the device moreover comprises a second electrical contact element for the electrical contacting on a second location of the workpiece, and wherein the first and the second electrical contact element can be positioned at a settable spatial distance to one another, so that on moving the roller burnishing element on the workpiece, a current path in the workpiece between the first and the second contact element is always equally long.
