Abstract
A roller burnishing device for sizing and/or finishing the external surface of a workpiece having a circular sectional contour by causing a relative rotation between the workpiece and a plurality of truncated conical rollers arranged within a head having a truncated conical inner surface. In this device, the head is made nonrotatable and instead a hollow cylindrical cage supporting the rollers within the head is driven in rotation to rotate the rollers at a high speed and the rollers are caused to orbit by driving the cage in low speed rotation thereby causing the rollers to make a planetary motion within the head.
