Rolling tool and roller for rolling, particularly deep rolling, a work piece

摘要

Previously known mechanical deep rolling tools share the feature that their rollers not only roll over the work piece but also over a counter roller on the tool side. This allows the deep rolling roller to swing to the side; but the roller material becomes fatigued relatively quickly. To achieve longer life, a rolling tool is suggested in which a working periphery is located in a work piece contact area spatially separated from a bearing contact area of the roller. A rolling tool with a hydraulically supported forming roller and a roller suitable therefor are also suggested.
