Provided is an automatic polishing system that allows a polishing treatment of an article while circumventing a polishing averting portion of the article. A polisher is attached to a leading end portion of a movable arm of a work robot. A control device controls the work robot and the polisher, based on position information of a polishing target surface of an article, so that the polisher is moved along the polishing target surface by a movement of the work robot while providing a polishing action on the polishing target surface at the same time. An image of the article including an image of an area demarcation marker annexed to the article for demarcating the area of the polishing target surface is captured by a three-dimensional image capturing machine. The control device produces the position information of the polishing target surface by determining the position of the area demarcation marker based on image data of the image.

The present invention relates to a device (14) for sanding floor areas, the device comprising a frame, a steering, a motor which is provided to said frame, a subframe (13) rotatably coupled with said motor, said subframe being centrally provided with an adapter (7) along the lower side, a sanding frame (1), said sanding frame being centrally provided with a receiver (2) along the upper side, said receiver receiving said adapter, and at least one holder (5) for sanding elements, said holder being provided along the lower side of said sanding frame and being suitable for the attachment of sanding elements (15). In particular, the subframe is freely supported by the sanding frame, via said adapter and receiver, said adapter and receiver being rotationally coupled. In other aspects, the invention relates to a sanding frame, a sanding element and a method for sanding floor areas, as well as a floor area obtained by application of said method.

A tire pre-conditioning system includes a first mandrel, a second mandrel spaced apart from the first mandrel, and a controller in communication with the first mandrel and the second mandrel. The first mandrel is fixedly attached to a first shaft and including a first tapered sidewall. The second mandrel is fixedly attached to a second shaft and including a second tapered sidewall. The controller is operable to axially move the first mandrel and the second mandrel toward one another until the first and second tapered sidewalls are opposing respective beads of a tire, and supply pressurized fluid into an internal cavity of the tire to inflate the tire. The inflating causing the beads to move relative to mandrels while contacting the opposing respective tapered sidewalls to burnish the beads of the tire.

The present invention discloses a device for removal of wheel rim burr which comprises a main body, plural positioning wheels, an eccentric wheel disposed on the main body, and at least two brush wheels disposed between two corresponding positioning wheels.

The present disclosure provides an adjustable device for removing burrs of a back cavity of a wheel. The adjustable device for removing the burrs of the back cavity of the wheel includes a frame provided with a rotary table inside, a support frame is fixedly connected to the rotary table, and a left rotary table and a right rotary table are arranged on the support frame. The device is ingenious in design, novel in conception, high in universality, short in cycle time and high in efficiency, and is suitable for removing burrs of wheels in different specifications.

The present invention provides a roll shaft having high corrosion resistance and rigidity against bending, and a brush roll comprising the roll shaft. The roll shaft 2 is for use in a brush roll 1 for brushing a strip of metal sheet. The roll shaft includes: a shaft body 7 to which multiple annular discs 4 having multiple brush bristles 5 implanted around the outer peripheral edge of the discs 4 are attached; key bases 8 attached to recessed grooves 72 provided on the outer peripheral edge of the shaft body 7, the key bases comprising keyways 80 into which insertion members 6 projecting from the inner peripheral edge of the annular discs 4 are fitted, and the key bases 8 comprising a corrosion-resistant metallic material, a corrosion-resistant alloy, or a corrosion-resistant resin material.

A grinder selection device includes: an input unit that inputs a grinding condition for a workpiece as a grinding target of grinding machining including at least the geometry of the workpiece and vibration data indicating vibration of a grinding machine, and grinder information about one or more grinders as grinder candidates to be used for the grinding machining; a learned model acquired through supervised learning using training data containing input data and label data, the input data containing an arbitrary grinding condition for a workpiece as a grinding target of grinding machining by an arbitrary grinding machine including at least the geometry of the workpiece and vibration data indicating vibration of the grinding machine, and grinder information about an arbitrary grinder, the label data being data indicating the adequacy or inadequacy of a combination between the grinding condition and the grinder information about the grinder; and a judgment unit.

A wafer grinding method includes a step of forming a protective member on one side of a wafer, a first grinding step of grinding the other side of the wafer by setting a chuck-table rotating shaft and a grinding-stone rotating shaft at a first tilt correlation that has taken into consideration sinking of the wafer by compression of the protective member during grinding, and a second grinding step of grinding the wafer on its one side to a predetermined thickness by setting the shafts at a second tilt correlation such that a lower surface of the grinding stone, where the grinding stone is to be in contact with the wafer, and the holding surface become parallel, and bringing the grinding stone into contact at its lower surface with a radial segment of the one side of the wafer.

A workpiece supporting device (6) includes a base stand (10), a shoe (11) which is disposed on at least one place in a circumferential direction of a workpiece (1a) that is rotationally driven using a rotary drive device (4) and is in sliding contact with a circumferential surface of the workpiece (1a), and a supporting body (12) which supports the shoe (11) with respect to the base stand (10). The supporting body (12) includes a compliant structure portion (a leaf spring (14)) which tilts the shoe (11) in accordance with tilting of the workpiece (1a) with respect to the base stand (10).
