Conditions for applying of tools for the finishing processing of holes through surface plastic deformation

The schemes of tools for Surface Plastic Deformation (SPD) in processing holes is the most spread method in the processing engineering. Rotation rolls (balls, cone-shape or spherical rolls) are being used as deforming elements. They deform through axial feeding, rolling over the processed surface. There are two main groups of tools – “Tools operating with axial feeding“ and “Tools with radial feeding“. The main feature of the tools with axial feeding is the helical character of the trajectory of the deforming elements on the processed surface. These tools have some disadvantages which could be avoided by using the tools with radiall feeding, the tools with periodical radial feeding and the tools with dynamic work.
