Disclosed is a device for automatically removing burrs from a riser of an aluminum alloy wheel. The device is composed of a frame, a clamping gear rack structure, a support plate, a servo motor and the like. When a clamping cylinder drives a first sliding plate to move, clamping wheels are controlled to center and clamp the wheel, and the servo motor controls the rotation of the clamping wheels, so that the wheel may rotate while being clamped. When a distance adjusting cylinder drives a second sliding block to move, a first sliding block and the second sliding block move synchronously under the action of a feed gear rack structure, so that a first deburring tool and a second deburring tool move synchronously to adjust the distance between them according to the diameter of a cap slot.

In one aspect, a swiss-type machine tool is provided that includes a workpiece holding shaft, a workpiece supporting shaft, and a tool holder associated with the workpiece supporting shaft for holding at least one tool. The machine tool includes a drive operable to rotate the workpiece holding shaft and the workpiece supporting shaft around an axis. The workpiece holding shaft has a work holder configured to secure a workpiece to the workpiece holding shaft. The workpiece holding shaft is axially shiftable relative to the workpiece supporting shaft to adjust a position of the workpiece relative to the workpiece supporting shaft. The machine tool further includes a removable workpiece support, such as a guide bushing, configured to be releasably connected to the workpiece supporting shaft and rotate therewith. The workpiece support slidably contacts the workpiece and permits axial movement of the workpiece relative to the workpiece support.

A physically crosslinked, closed cell continuous foam structure derived from recycled metallized polyolefin material; polypropylene, polyethylene, or combinations thereof, a crosslinking agent, and a chemical blowing agent is obtained. The foam structure is obtained by extruding a structure comprising a foam composition, irradiating the extruded structure with ionizing radiation, and continuously foaming the irradiated structure.

A cellulose fiber-based substrate, at least one side of which is coated with an aqueous mixture composed of: a) at least one water-soluble polymer (WSP) containing hydroxyl groups, b) at least one lactone substituted with at least one linear or branched and/or cyclic C.sub.8-C.sub.30 hydrocarbon chain which may contain heteroatoms, c) at least one crosslinking agent. A method of production and use thereof.

A method for producing a barrier layer and a carrier body including such a barrier layer are disclosed. In an embodiment the method includes providing a carrier body including a polymer film having at least one polymer, drying the barrier interface, exposing the barrier interface to one reagent gas, or to a plurality of reagent gases which do not chemically react with each other, so that the at least one reagent gas chemically reacts with the at least one polymer at least inside the polymer film in at least one chemical reaction thereby forming the barrier layer, and removing at least one product gas of the at least one chemical reaction.
