Abstract:
1. A burnishing tool, comprising: a tapered cam shaft, wherein the tapered cam shaft includes camming surfaces having a planar spatial orientation substantially the same as the planar spatial orientation of sides of a pyramid, wherein respective keys respectively extend along respective camming surfaces of the tapered cam shaft, the keys having respective longitudinal axis of extension parallel to the respective camming surfaces, and wherein the camming surfaces are arrayed about a cam shaft axis that is normal to a plane that is parallel to a base of the pyramid; a burnishing assembly, the burnishing assembly including: a carrier assembly, the carrier assembly applying force on the segmented burnishing components to hold the segmented burnishing components against the tapered cam shaft; wherein the burnishing tool is configured to permit adjustment of the position of the burnishing assembly with respect to the tapered cam shaft in the direction of the cam shaft axis to advance and retract the segmented burnishing components in a radial direction with respect to the cam shaft axis due to movement of the cammed surfaces of the segmented burnishing components along the respective camming surfaces of the cam shaft.
