Abstract

A device for electromechanically assisted roller burnishing (EMRB) may comprise: a roller burnishing tool with exactly one current-leading roller burnishing element for burnishing a workpiece, wherein the roller burnishing element represents a first electrical contact element for electrically contacting first location of the workpiece, and a second electrical contact element for electrically contacting second location of the workpiece; wherein the first and the second electrical contact elements 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 elements is always a constant length.
