摘要： Apparatus and method for the manufacture of improved abrasive tools and the like which includes apparatus and a method for the creation of a structurally viable matrix having a pattern of abrasive elements which can be shaped, cut and positioned for permanent disposition on a rigid tool body. The apparatus includes a transversely magnetized base surface with magnetic protrusions to provide a mosaic-like surface. A release layer is placed over the protrusions and magnetizable abrasive particles are diffused onto the surface of the release mechanism. The particles orient themselves magnetically to form generally conic stacks which having a stack axis and a distal working portion. The stacks define a working surface which is then coated with acrylic paint to provide structural integrity. Prior to solidification of the paint the cones may be shaped, for example, by passing a magnet near them. After the cones have been shaped and the paint dried, a braze paste is applied to encapsulate the cones and form a flexible support web between the cones. The entire matrix may then be removed from the base surface and cut and formed to any desired shape. The release mechanism may then be removed and the matrix secured to a rigid structure using an acrylic adhesive. At this point, the matrix and structure may be heated to braze temperature to form an assembly featuring a high-friction surface used as an abrasive tool.

摘要： Abrading tools having shaped solid bodies composed of wearable matrix material and embedded fibers of harder abrasive material with ends exposed at the working surfaces of the tools and constituting the abrasive or cutting elements of the tools. In one case, a honing stone has closely spaced cylindrical fibers arranged in rows of fibers substantially perpendicular to the working face, which has a slight transverse curvature, and alternate arrangements inclined relative to the face so that the ends are oval. In another case, an abrading wheel has radial fibers and another has longitudinal fibers for end-working applications. Suitable fiber materials for machining metals may be boron and boron compounds.

摘要： The present invention is a fixed abrasive article for grinding or polishing the surface of a glass workpiece. The abrasive article for grinding glass has abrasive composites containing a binder, an alkaline metal salt, and diamond abrasive particles or agglomerate particles comprising diamond particles, the composites integrally molded to a backing. The abrasive article for grinding glass is capable of removing between about 200 and 400 micrometers of glass using an RPP procedure having a polish time interval of between 10 and 15 seconds, generally about 12 seconds. The abrasive article for polishing glass comprises a backing containing fibers, and a plurality of abrasive composites integrally molded to the backing comprising an organic resin, ceria abrasive particles, and alkaline metal salt. The abrasive articles for polishing glass also provide an optimum rate of breakdown of the abrasive composites and improved adhesion between the abrasive composites and the backing.

摘要： A sheet-shaped grindstone for grinding a workpiece includes a plurality of segments arranged in an appropriate pattern with sufficient spaces therebetween such that the grindstone becomes flexible. The segments are formed in a manner in which metal powder including diamond grinding grains is sintered to form granular chips, the chips are disposed in a die in such a density that the chips come into mutual contact, and gaps around the granular chips are filled with a resin through application of pressure. The grindstone is more flexible at contact points with a workpiece than are conventional vitrified grinding tools. The grindstone can evade collision of the segments with the workpiece and can grind a curved surface of the workpiece through smooth contact therewith.

摘要： In a rotary tool adapted for grinding under a flowing liquid film, wherein the particles of abrasive are metal-bonded to a rigid supporting surface, the improvement consists of a network in the supporting surface of grooves having constant depth and constant width and traversing said supporting surface to provide a continuum of centrifugal drainage grooves in the radial direction thereby subdividing said supporting surface into working elements. The ratio of the total area (A.sub.E) of said working elements to the total area (A.sub.G) of said network of grooves: A.sub.E /A.sub.G is at least 1.5. The configuration of the network of grooves is selected such that the angle of intersection of any side of any channel with the radius at any point is an acute angle between 0.degree. and 75.degree..
