ABSTRACT:
A portable machining device that is particularly useful for removing excess peripheral weld from the flat surface of welded-in valves such as breech lock gate valves. The portable machining device includes a housing, a cutting tool, a vertical feed mechanism, a horizontal feed mechanism, and a rotation drive mechanism. The vertical feed and rotation drive mechanisms have central openings for receiving the upward extending valve stem from the surface to be machined. The base of the housing is ring shaped and includes slots for attachment to the flat surface of the valve. In operation, the cutting tool is rotated and fed vertically and horizontally to machine the excess weld to be flush with the flat surface.
