ABSTRACT:
A method of machining pipe at high speeds is disclosed that includes the steps of moving the pipe from a pipe rack onto a conveyor, moving the pipe longitudinally into the chuck of a threading machine or the like, clamping the pipe in the chuck, transferring the pipe from the conveyor to one or more steady rests, and supporting the steady rests on flexible wall air cylinders that will allow the steady rest to move as required to support the pipe which, because it is not straight, will whip and move laterally as it is rotated at the speeds required for high speed machining.
