ABSTRACT:
A process and apparatus for machining the inner surface of a pipe where a tool carrier is positioned adjacent the area to be machined and a cutting tool is advanced about a pivot axis around the inner surface of the pipe, while also having a pendulum movement of the tool holder in a direction parallel to the pivot axis. The pendulum axis is perpendicular to the pivot axis, while the pivot axis is parallel to the axis of the pipe. The apparatus has a transporter to move it into location and motor drives to pivot a tool holder and provide the pendulum movement. A distance sensor and adjustment apparatus maintains a supporting member carrying the tool holder at a desired radial position relative to the inner surface of the pipe.
