摘要： Methods of making thin abrasive cut-off wheels with low pinhole occurrence are disclosed. An abrasive cut-off wheel has a thickness of less than or equal to 1.6 millimeters. It comprises at least one reinforcing scrim and abrasive particles retained in a phenolic binder. The abrasive particles comprise first and second triangular abrasive platelets. The first triangular platelets have a first average maximum side length and a first total weight. The second triangular platelets have a second average maximum side length and a second total weight. The first and second total weights combined comprise at least 30 weight percent of the abrasive cut-off wheel. The ratio of the first average maximum side length to the second average maximum side length is 1.25:1 to 5:1, and the ratio of first total weight to the second total weight is 1:2 to 5:1.

摘要： An abrasive tool includes a tool base having a supporting surface and a generally cylindrical abrasive surface layer disposed on the supporting surface. The abrasive surface removes material from a work-piece outer surface by contact therewith and by relative movement along a defined working path. The abrasive tool comprises a first axially extending circumferential portion featuring an abrasive coating selected to produce a final finish on the work piece, and a second trailing portion that tapers radially inwardly to accommodate post-grind radial expansion of the work piece.

摘要： A bonded abrasive wheel comprises magnetizable abrasive particles retained in an organic binder. The bonded abrasive wheel has a central portion adjacent to a central hub, an outer circumference and a rotational axis extending through the central hub. The magnetizable abrasive particles adjacent to the central hub are aligned at an average angle of less than 35 degrees with respect to the rotational axis, and the magnetizable abrasive particles adjacent to the outer circumference of the bonded abrasive wheel are aligned at an average angle that is from 35 and 90 degrees, inclusive, with respect to the rotational axis. Methods of making a bonded abrasive wheel are also disclosed.

摘要： A device for reforming a vessel cavity is provided that includes a central shaft, a central gear coupled to the central shaft, and a plurality of roller gears coupled to the central gear, with each of the plurality of roller gears having a central portion. A proximal support member couples the plurality of roller gears and at least one of the central gear and the central shaft. A plurality of rollers is also provided, each of the plurality of rollers connected to the central portion of each of the plurality of roller gears. In one form, at least one idler member is disposed between the plurality of rollers. A distal support member couples the plurality of rollers and at least one of the central gear and a translation member. Also, a stationary member is secured to a distal portion of the vessel cavity.

摘要： A roller assembly for a rotary dresser comprise a plurality of axial segments which may be in the form of discs, each disc provided with an abrasive, radially outer surface. The discs are secured in axial alignment, each in a preconfigured rotational orientation. The disc assembly has a centrally arranged aperture for receiving a rotor shaft. The abrasive surface of the assembly can be accurately presented as an array of uniformly shaped abrasive units in a predefined pattern.

摘要： A manufacturing apparatus, of a grinding stone which is manufactured by attaching abrasive grains respectively having polyhedral shapes in which mutually opposed surfaces are parallel to each other to a base member, is provided with: an abrasive grains classifying apparatus adapted to classify the abrasive grains based on sizes of the abrasive grains defined by face-to-face distances between the mutually opposed surfaces; and an attaching apparatus adapted to attach the abrasive grains classified by the abrasive grains classifying apparatus to the base member. The attaching apparatus is provided with: a template which is disposed above the base member to be movable with respect to the base member and formed with a guide hole through which the classified abrasive grains pass; a vibration generator connected to the template or the base member and adapted to apply a vibration to the abrasive grains passing through the template; and an electrolytic deposition bath adapted to electrolytic deposit the abrasive grains passing through the template.
