The elastomerically deformable supporting layer may be adhesively bonded onto a metallic supporting body.

A disc changing system for a robotic defect repair system is presented. The system has a first abrasive disc and a second abrasive disc. The first and second abrasive discs are coupled to a liner. The system includes an abrasive disc placement device configured to automatically: remove the first abrasive disc from the liner, transport the first abrasive disc to a robotic tool of the robotic defect repair system, and place the first abrasive disc on a backup pad coupled to the robotic tool. The system also includes an abrasive disc remover configured to automatically remove the first abrasive disc after receiving a removal signal. The system also includes a controller configured to send an instruction to the disc placement device to remove, transport and place the first abrasive disc, instruct the robotic tool to conduct an abrasive operation. The controller is also configured to send the removal signal. The controller is a processor and the instructions are stored on a non-transitory computer-readable medium and executed by the processor.

An abrasive tool, including an abrasive carrier (1) having a shaft (2) for connecting the abrasive carrier (1) to a driving device for rotatably driving the abrasive carrier (1) about a longitudinal axis (X) and having a core (3) connected to an axial end (4) of the shaft (2), and an abrasive article (15) having a surface (16) being circumferentially closed about the longitudinal axis (X) and enclosing a cavity (17) extending along the longitudinal axis (X), wherein the core (3) is accommodated at least partially in the cavity (17), and wherein the core (3) includes a material mixture which includes a plastic with a heat-conductive filler, wherein the plastic is foamed, and wherein the filler has a thermal conductivity greater than 35 watts per meter and per Kelvin.

A sanding tool attachment includes an annular attachment body, a plurality of dust extraction holes, a tool fastening feature, a primary hook fastening feature, and a secondary fastening feature. The annular attachment body includes a first base wall, a second base wall, a lateral wall, and a central axis. The plurality of dust extraction holes is radially distributed around the central axis and traverses from the first base wall to the second base wall. The tool fastening feature is integrated onto the first base wall so that the sanding tool attachment can be secured to a random orbital sander. The primary hook fastening feature is integrated onto the second base wall and removably secures existing round sanding pads to the sanding tool attachment. The secondary fastener feature is integrated onto the lateral wall thus fastening a rectangular sanding strip to the sanding tool attachment.

Disclosed herein are polyurethanes useful for polishing layers, where the polyurethane is a polyurethane having a Schiff base. Also disclosed herein are polishing layers containing the polyurethanes, polishing methods that use the polishing layers, and a modification method including a step of converting the Schiff base into at least one functional group selected from an aldehyde group, a carboxylic acid group, a hydroxyl group, and an amino group.

An object of the present invention is to provide a grinding material in which grinding portions can be increased in thickness while a decrease in grinding rate is inhibited. The grinding material according to the present invention includes a base, and a grinding layer overlaid on a front face side of the base and containing abrasive grains and a binder. The grinding layer includes a plurality of columnar grinding portions. The plurality of the grinding portions are configured so that the grinding portions are arranged in a staggered manner. The average thickness of the grinding portions is no less than 300 m. The area of a top face of each of the grinding portions is no less than 6 mm.sup.2. The average thickness of the base is no less than 300 m and no greater than 3,000 m.
