A pipe cutting apparatus includes a machine base having a first machine table slidably secured for moving with a pipe during the extrusion thereof. The apparatus includes a rotary base table with a cutting arrangement attached at a periphery thereof such that the cutting arrangement orbits about the pipe during cutting thereof. The cutting arrangement includes a cutting tool supported on a pivoting support arm. The support arm includes a powered gear drive train for pivoting the support arm to accommodate different sizes of pipe and to allow cutting. The cutting apparatus has a second slidable table to allow precision cutting of multiple cuts of the pipe while the pipe remains clamped or held. The clamp arrangement is supported on and movable with the second slidable table. A controlled actuator is used to move and determine the relative position of the slidable tables.
