ABSTRACT:
An apparatus and a process for burnishing annular surfaces. The apparatus includes a burnishing tool which is actuated to rotate in one direction and then in the opposite direction. The apparatus is used for the burnishing of annular thrust bearings which have oil wick slots and wick slot oil ramps. A rack and pinion connects a tool mounting spindle to an air cylinder and is used to rotate the tool in one direction and then the other direction. The tool has a convexly shaped burnishing surface. The tool's axis of rotation is coaxially aligned with the central axis of the annular surface. The rotation of the tool in one direction and then in the other direction burnishes the thrust surface and the wick slot oil ramps of the bearings. The opposite ends of the rotational burnishing strokes locates the tool in the wick slots so as to leave no stopping imperfection on the thrust surface of the bearing.
