ABSTRACT:
A ring-blade saw for cutting a tube generally centered on a tube axis has a subtantially stationary base, an outer frame displaceable in a straight line in a plane, and an actuator connected between the base and the outer frame for displacing the frame relative to the base in the plane. An inner support is carried by a first guide on the frame for movement relative to the frame in a first straight direction lying in the plane and by a second guide for movement of the support relative to the frame in a second straight direction lying in the plane and perpendicular to the first direction. A generally planar, annular and internally toothed saw blade lying generally on the plane, centered on a saw axis generally perpendicular to the plane, and carried on the support can be rotated on the support about this saw axis. Thus the tube to be cut can extend through the blade with its axis parallel to or on the blade axis. A drive including a crank is connected between the frame and the support for orbiting the saw axis about the tube axis of a tube extending perpendicular to the plane through the blade. Thus when the blade is being rotated and orbited it can cut through the tube passing through it.
