ABSTRACT:
A pipe bevelling tool arrangement for providing a predetermined bevel on the end surface of a pipe. The arrangement described herein provides an orbital cam follower bevelling tool that provides a constant bevel leaving a radially extending land on the end surface of a pipe having a predetermined minimal radial extent regardless of the "out-of-round" condition of the pipe. A cam is mounted to engage the exterior surface of the pipe and a bevelling tool is rigidly coupled to the cam and the cam and bevelling tool orbit around the nominal center line of the pipe. The cam and the pipe bevelling tool are resiliently mounted on a rigid arm rotating about the nominal center line of the pipe and the pipe bevelling tool follows movement of the cam in a radial direction. The pipe bevelling tool is set in a preselected position with respect to the cam to provide the desired bevel portion and extent of the radially extending portion on the end surface of the pipe.
