摘要： An abrasive segment includes a carrier body for attaching the abrasive segment to a lateral surface of an abrasive roll in an interlocking manner; and a substantially planar abrasive layer. The abrasive layer is oriented substantially parallel to the lateral surface of the abrasive roll in a state of the abrasive segment in which it is attached to the abrasive roll, and an elastic intermediate layer is located between the carrier body and the abrasive layer.

摘要： For use with a power trowel, an abrasive assembly attachable to a rotatable arm of the power trowel that comprises a circular, rigid plate having a central hub projecting out from a first major surface and affixed to its second major surface is a ring of a resilient material. Adjacent the resilient ring is a molded plastic ring in which a plurality of permanent magnet members are imbedded at regularly spaced intervals. The plastic ring further includes at least, one boss projecting outward from a surface thereof and designed to fit within an aperture disposed in an outermost ring, which is entirely or partially of a ferrous metal and which carries a plurality of abrasive members on its outer surface. The resilient ring is fastened to the rigid plate by internally threaded tubular pins and the plastic ring is secured by screws that pass through the plastic ring into the lumens of the internally threaded tubular pins.

摘要： A grinding wheel includes a disc-like member and a grinding layer disposed on an outer peripheral surface of the disc-like member. The grinding layer includes a plurality of circumferentially-divided grinding chips which are divided in a circumferential direction. Each of the circumferentially-divided grinding chips is formed by arranging a first grinding chip and a second grinding chip in the axis direction, the first grinding chip and the second grinding chip having different properties. A boundary portion between the first grinding chip and the second grinding chip of at least three circumferentially-divided grinding chips continuously arranged in the circumferential direction are arranged toward a predetermined direction in the axis direction in the order in which the circumferentially-divided grinding chips are arranged.

摘要： A segment for an abrasive article is disclosed. The segment can include a segment body that can have a first face that can extend along a length of the segment body on a first side of the segment body and a second face that can extend along the length of the segment body on a second side of the segment body opposite the first side. A gullet wall can extend from the first face to the second face. The gullet wall can extend along a gullet. The segment can also include a recessed region that can extend into one or both of the first and second faces. The recessed region can include a gullet portion extending at least partially along the gullet wall.

摘要： A segmented profiled wheel for grinding a glass or non-metallic workpiece including a segmented abrasive portion formed of a plurality of abrasive segments that are attached to a core of the wheel and method for making same. The plurality of abrasive segments have a cutting surface profile and sufficient abrasive grit to contour and grind the workpiece. Terminal ends of the plurality of abrasive segments are adjacent to one another and the cutting surface profiles align to form a substantially continuous rim of profiled abrasive segments for substantially continuous contact with a workpiece while the wheel rotates. The method includes the steps of forming the plurality of abrasive segments having a metal bonding matrix using automated processes, machining a metal blank to form a core, and attaching the plurality of abrasive segments to the core by laser welding and/or brazing.
