Burnishing tool and method for burnishing

摘要

A method for providing a surface treatment along the surface of a work piece, using a burnishing tool having a tool head comprising a bearing for supporting a rolling element and an encasement for supporting the bearing. The bearing is formed from a polymer or polymer resin such as, but not limited to, polytetrafluoroethylene based resin, ultra-high-molecular-weight polyethylene based resin.

主权项

1. A method of burnishing comprising the steps of:
performing a burnishing operation along at least a portion of the surface of the work piece using a burnishing tool comprising at least one tool head having a rigid encasement supporting a bearing formed from a softer polymer or polymer based resin material, and a rolling element supported by the bearing; and moving the rolling element along the at least a portion of the surface with sufficient force to produce a desired magnitude of residual stress along and within the surface of the work piece.
