Abstract
A burnishing tool and method for providing a surface treatment along the surface of a work piece, the 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 self-lubricating polymer such as, but not limited to, polytetrafluoroethylene based resin, ultra-high-molecular-weight polyethylene based resin.
Claims22
A burnishing tool for burnishing the surface of a work piece comprising:
- a rolling element that operates to contact the work piece and induce compressive residual stress along and into the surface of the work piece;
- a bearing for supporting said rolling element, wherein said bearing is directly adjacent to said rolling element;
- and
- a rigid encasement that supports said bearing and does not deform during operation of the burnishing tool;
- wherein said bearing is formed from a polymer or polymer resin.

A burnishing tool for performing a burnishing operation on a work piece, the burnishing tool comprising:
- at least one tool head having a bearing formed from a polymer based material, an encasement for supporting said bearing and does not deform during operation of the burnishing tool;
- and
- a rolling element supported by said bearing, wherein said bearing is directly adjacent to said rolling element;
- a machine tool coupled to said at least one tool head for directing said at least one tool head across the surface of the work piece for inducing compression along and into the surface of the work piece;
- and
- a control system coupled to said machine tool for directing the burnishing operation.
