A tool holder 1 has a shaft 2 intended to be arranged in a tool holder in a manufacturing machine, a head 3 on which a cutter is intended to be arranged and a vibration-damping material 4 arranged between, and attached to, the shaft 2 and the head 3 such that the cutter is in contact with the manufacturing machine solely through the vibration-damping material 4, where the vibration-damping material is a metal or an alloy of metals selected from the group consisting of Cu, Ti, Zn, Al and Ni. A method for manufacturing a tool holder in which the surface covering of vibration-damping material is created by electrochemical pulse plating through the tool holder, when functioning as an electrode, being lowered into an electrolyte containing ions of at least one metal selected from the group consisting of Cu, Ti, Zn, Al and Ni.

A substantially conical tool body 1 has a groove 11 extending in the direction of generating line. The groove 11 slidably receives a slider 16 carrying a cutting insert 5A. A spacer 12 having serration grooves 12a is interposed between one wall surface 11a of the groove and the slider 16. Serration grooves 16a are formed in one side surface of the slider 16. A wedge member 13 is detachably interposed between the wall surface 11b of the groove 11 and the slider 16 so as to press the slider 16 to bring the serration grooves 12a16a into engagement with each other. Any wear and deformation due to cutting load appear on the spacer 12 and the wedge member 13, so that original mounting and positional precision of the slider 16 can easily be recovered by renewing these members, thus maintaining a required level of machining precision.

A laminate having an electroluminescent element disposed within the laminate is disclosed. The laminate includes a first paper layer having at least first and second vias through the first paper layer; a first electrically-conductive layer comprising an electrically-conductive material, the first electrically-conductive layer being disposed over the first paper layer; a dielectric layer disposed over the first electrically-conductive layer; a light emissive layer comprising an electroluminescent material, the light emissive layer being disposed over the dielectric layer; a second electrically-conductive layer comprising a translucent electrically-conductive material, the second electrically-conductive layer being disposed over the light emissive layer; an insulating layer disposed over the second electrically-conductive layer. The first paper layer and the insulating layer encapsulate the first electrically-conductive layer, the dielectric layer, the light emissive layer, and the second electrically-conductive layer.

摘要:
The present invention solves the problems encountered by conventional machine tool devices when metals, plastics, composites or other materials are cut. The Sizing Tool is capable of precisely and permanently changing the shape of a tubular workpiece because, unlike conventional static spreaders, it repeatedly bends the workpiece back and forth many times to achieve the desired deformation. The Sizing Tool includes a set of revolving rollers (14) supported by bearings (13) and a mounting plate (12). The roller (14) is capable of engaging either the inside or outside surface of a hollow metal tube (10). The rollers (14) exert force on the end of the tube (10) having a circular cross-section in a configuration that resembles a polygon inscribed in a circle. As the rollers (14) are moved toward the workpiece (10), the workpiece is gradually deformed as it moves farther into the inclined surface presented by each roller (14). The dynamic flexure flaring method provided by the present invention enables a technician to work harden and produce precisely formed surfaces within a tolerance of one-thousandth of an inch which can be relied upon to maintain their shape over long periods of time. The Cutting Tool is controlled by an innovative tool advance assembly that converts translational motion to precise radial motion which governs the action of the cutting bit as it severs a tubular workpiece (10). The Cutting Tool is not only capable of cutting a tubular workpiece (10) from the inside out, but can also be configured to cut a tube (10) from the outside.

The present invention solves the problems encountered by conventional machine tool devices when specialty metals such as titanium, Inconel.TM. and stainless steel are sized, cut or welded.

摘要:
High frequency vibrations of a boring bar cutting tip are minimized by use of a damping sandwich of plural layers of steel and plural alternate layers of viscoelastic solid material. This damping sandwich is placed at a joint in the machine tool between the cutting tip and a tool mounting area, and is shown as being provided between a mounting face of a tool mounting block and a mounting area. The damping sandwich permits greater depth of cut, with greater inches per revolution of chip removal without any chatter for improved metal removal.
