A workpiece holding device for holding a workpiece in a heat treatment system while the workpiece undergoes a thermal expansion and/or contraction includes at least two clamping units configured to apply a radial and/or an axial clamping force to the workpiece to hold the workpiece in the workpiece holding device in a predefined position, and at least three support units configured to support the workpiece. At least one of the support units includes a carrier and an exchangeable support element attached to the carrier, the exchangeable support element being configured to contact and rotatably support the workpiece in the predefined position.

Device for machining an end of an elementary panel for its subsequent friction stir welding, the elementary panel comprising a metal body defining two opposite faces, the machining device comprising a chassis, at least two guiding members configured to guide a first face of the elementary panel, at least one machining tool mounted on the chassis, the machining tool being positioned between the two guiding members and at least one pressure member mounted on the chassis and configured to exert a pressure on a second face of the elementary panel so as to press the elementary panel against the guiding members along the horizontal reference direction.

A vacuum suction nozzle is provided, including a first housing, a second housing, an accommodating space, a gap, and a clamping assembly. The first housing includes a first lateral wall, a first lower surface, a channel, and a through hole. The through hole is formed on the first lateral wall. The second housing is fixedly connected to the first housing, and includes a second lateral wall and a second lower surface. The accommodating space is formed between the first lateral wall and the second lateral wall, and the through hole is opened onto the channel and the accommodating space. The gap is formed between the first lower surface and the second lower surface, and is opened onto the accommodating space. The clamping assembly is disposed in the accommodating space.

A sawhorse support attachment device for attaching supports for construction use includes a stand unit. The stand unit comprises a pair of bases, a plurality of stands, and a pair of chains. Each of the bases has a hollow interior that defines a space for an insert to be nested within. A pair of stands is attached to each of the bases at an angle to create a sawhorse assembly when in an open position. A pair of chains connects each of the pair of stands to each other. The chains provide supplemental stability to the stand unit when attaching elements. A support has a bracket with a pair of inserts. The pair of inserts is nested into the hollow interior of the pair of bases when attaching to the stand unit. A platform having the bracket and pair of inserts can attach to the stand unit.

A crimping system for a prosthetic heart valve comprises a split funnel comprising an elongated annular body having an enlarged insertion end, a narrower outlet end, and a central opening extending along a central longitudinal axis of the split funnel, between the insertion end and the outlet end. The body comprises first and second slots extending axially along opposite sides of the body from the outlet end toward the insertion end, the first and second slots defining first and second split portions of the body extending circumferentially between the first and second slots on opposite sides of the central opening. The crimping device is configured to crimp a prosthetic heart valve moving axially through the central opening from the insertion end to the outlet end while allowing portions of the prosthetic heart valve to protrude through the first and second slots and remain in an expanded configuration.

A machining tool assembly for manufacturing a firearm lower receiver includes a first and second side jig which are configured to be disposed on opposite sides of the firearm lower receiver and configured to removably attach to one another securing the firearm lower receiver therebetween. A drill block jig is removably attachable to the first and second side jigs disposed above the top surface of the firearm lower receiver, wherein the drill block jig has at least one through hole. A router support plate is disposed above and removably attachable to the first and second side jigs. A router aperture is disposed through a router support plate thickness.
