On Tool Support Having Reciprocation Parallel To Direction Of Work-feed Patents (Class 83/307.2)
  • Patent number: 8465227
    Abstract: A diamond wire saw and method provides a frame that includes a clamp that attaches to a target (e.g. piling, beam, tubular), an elongated toothed rack extending away from the mount and target, and a moving portion that carries the diamond wire and motor drives that advance the moving portion toward the target and along the toothed rack while driving the wire around roller guides.

  • Patent number: 8141611
    Abstract: A separation apparatus for separating two planar devices bonded together by an adhesive layer is provided. The separation apparatus includes a base, a sliding module, a cutting member, and a positioning stage. The sliding module is mounted on the base. The cutting member is connected to the sliding module and is moveable in a two-dimensional plane with respect to the base by the sliding module for cutting the adhesive layer. The positioning stage is mounted on the base for positioning the planar devices and the adhesive layer therebetween on the base.

  • Patent number: 6742424
    Abstract: An apparatus for cutting green ceramic bodies, includes a traveling path for green ceramic bodies, beds for supporting green ceramic bodies at constant intervals in series along the traveling path, an arm on each side of the traveling path, two drive portions for moving respective arms perpendicularly relative to the traveling path, a drive portion for moving both arms in the same direction as the traveling path, a wire for cutting green ceramic bodies, extending between the arms, and wire supporting portions, on respective arms. Each wire supporting portion includes a servo motor with an axis of rotation, a magnet member around the axis of rotation, a bobbin having a conical surface around which wire is wound, and magnetically coupled to the axis of rotation by the magnet member, and a traversing mechanism for varying the position where the wire is wound around the length of the conical surface.
