Abstract
A cam-controlled tube end finishing apparatus includes a cutting bit having multiple cutting faces, a platform supporting the cutting bit adjacent to the end of a rotating hollow tube, and a pair of cam-controlled mechanisms for moving the platform and thereby the cutting bit relative to the end of the rotating tube along a closed polygonal path of travel for severing the tube end. An initial portion of the rotating tube is severed in a direction from the outside to the inside of the tube at an angle to a plane normal to the rotational axis of the tube so as to define an initial cut face on the tube end extending in inclined relation to a plane normal to the rotational axis of the tube. A final portion of the rotating tube is severed in a direction from the inside to the outside of the tube at another angle to a plane normal to the rotational axis of the tube so as to provide a substantially burr-free cut face on the tube end extending in a plane normal to the rotational axis of the tube.
