Description:

Abstract:

A surfacing machine mountable within a bore of a workpiece includes a turning bar supported by a bearing arrangement which permits rotational and axial movement of the turning bar relative to support chucks mounted on a workpiece. The arrangement facilitates both visual and physical access to the work site such that an operator may switch surfacing operations without changing the mounting alignment of the surfacing machine within the bore.
