  • Apparatus, system, and method for cutting tubes
    Patent number: 8091455
    Abstract: An apparatus, system, and method for cutting tubes has a scarf cut made in a direction transverse to a cut-off direction. The scarf cut passes through a thickness of a tube wall and forms an opening that receives a tip of a cut-off blade. The cut-off blade has cutting edges with an angle that engage ends of the opening such that a slug is forced upward and outward relative to the tubes. The scarf blade, the cut-off blade, and a clamping jaw may be moved in a coordinated manner by separate drivers operated under control of an electronic controller.
