    Patent number: 9089899
    Abstract: An apparatus for facing a flange of a pipe includes a housing and an anchor assembly rotatably supported by the housing. The anchor assembly is configured to engage an inner surface of the pipe. The apparatus further includes a tool holder translatably supported by the housing. The tool holder is configured to support a facing tool for facing the flange of the pipe. The apparatus further includes a drive shaft that is rotatable relative to the housing to translate the tool holder relative to the housing. The housing is rotatable relative to the anchor assembly about a first axis in a first direction and the drive shaft is simultaneously rotatable relative to the housing about a second axis in a second direction opposite the first direction to move the tool holder along a spiral path and thereby face the flange of the pipe.
