Abstract: A method of inspecting a workpiece for a processing machine includes the steps of placing a workpiece on a worktable, moving a spindle located above the worktable to allow a laser sensor mounted with the spindle to be close to the workpiece, measuring a distance between the laser sensor and the workpiece by a laser beam emitted from the laser sensor on the work piece, and gathering data of the workpiece, such as size, shape or location, by moving the spindle to enable the laser beam to pass through the periphery of the workpiece.

Abstract: An electromagnetic pick-and-place device for use with a processing apparatus is provided. The electromagnetic pick-and-place device essentially includes a fixing base, a fixing axle penetratingly disposed at the fixing base, and an electric magnet disposed at the fixing axle, which move together in operation so as to be positioned right above a workpiece. Then, the workpiece is gripped by suction with electromagnetic pick-and-place device under a magnetic force generated from the electric magnet. Afterward, the electromagnetic pick-and-place device and the workpiece move together to a processing position. Eventually, the magnetic force of the electric magnet is disabled in order to free the workpiece; at this point in time, the processing apparatus can start processing the workpiece.

Abstract: An electrode tube holding apparatus is mounted to an electric discharge machine (EDM). The holding apparatus is slidable upward and downward along with the spindle of the EDM and maintained within the midsection of an electrode tube for reducing the deformation of the electrode tube during its movement.

Abstract: A wire collecting mechanism for cutting and collecting a metal wire used in a wire-cut electrical discharge machine includes a first guide roller and a second guide roller movable relative to the first guide roller for clamping the metal wire that passes between the first guide roller and the second guide roller. A wire cutter is moveable relative to the metal wire for cutting the metal wire that is clamped. A wire collecting box is provided with a mouth facing the metal wire and a suction force towards an inside of the wire collecting box. A press roller is movable relative to the metal wire for pressing and forcing a cutting piece of the metal wire into the mouth of the wire collecting box, such that the cutting piece of the metal wire can be sucked into the wire collecting box.
