Abstract
To provide a roller-burnishing tool, for installing in a small machining center, small NC lathe and so forth. The frame for rolling compaction processing is coaxially connected with the shank portion which performs a rotary drive by mounting in a driving machine, and the mandrel is supported by this frame with a universal function for rotation. A tip end of the mandrel and the multiple rollers are formed into a taper shaped style for being supported for rotation from a radial direction. The mandrel and the compressing coil spring, which functions from the shank portion side to the frame side are provided in the shank portion as well as the adjustable ring, which allows adjustment of tool diameter by moving the position of the mandrel in an axial direction relative to the frame.
