  • Patent number: 6257110
    Abstract: A tube saw for precision cuts on tubing wherein a motorized circular saw is rotated about the circumference of a tube to cut it without leaving burrs, finishing marks or other deformations on the tubing. The tubing is held firmly and precisely by a plurality of facing triangular clamping elements and the clamping elements are centered and firmly locked in place relative the housing containing the saw to ensure the blade does not move relative the tube during the cut. The housing, rotatably holding the saw, has bearings with angular and radial stiffness to hold the saw firmly in position during the cut to ensure a high quality cut. A servomotor drives the rotatable portion of the housing at an even rate to cut the tubing with an even force and rate around its circumference. The saw is positioned close to the end of the clamping elements to limit bending and vibrations in the tubing from interfering with a square high precision cut.
