Abstract
An apparatus and method of refurbishing a valve seat disposed at a predetermined angle relative to the centerline of an associated valve bore in a workpiece wherein the apparatus includes a support structure on which the workpiece is located such that the centerline of the valve bore is aligned with a known reference axis. The apparatus further includes a tool having a lapping portion corresponding to the valve seat and a drive mechanism for moving the tool along the known reference axis such that the lapping portion is brought into engagement with the valve seat and for rotating the tool relative to the workpiece to lap the valve seat. The method generally includes locating the workpiece in a predetermined position such that the centerline of the valve bore is aligned with the known reference axis and moving the tool having a lapping portion corresponding to the valve seat along the known reference axis such that the lapping portion is brought into engagement with the valve seat. The tool is then rotated relative to the workpiece to lap the valve seat, and the tool is then moved along the known reference axis to disengage the lapping portion from the valve seat.
