ABSTRACT:
A machine tool for resurfacing seats surrounding non-circular openings in members, such as elliptical manways, includes a housing adapted to be mounted in the opening, and a tool bit carried by a slide mechanism mounted on the housing for rotation about a central axis. The slide member is resiliently biased outwardly to urge a tracker wheel into engagement with an inner surface of the opening, whereby the tool bit is constrained to follow the contour of the non-circular opening as it moves across the seat during a resurfacing operation. Movement of the tool bit across the surface being refaced is achieved by a feed screw driven from a feed sprocket that engages a tripper pin upon each revolution of the tool about the central axis.
