    摘要： A method of making shaped abrasive particles including forming an abrasive flake comprising a plurality of precursor shaped abrasive particles and a frangible support joining the precursor shaped abrasive particles together; transporting the abrasive flake through a rotary kiln to sinter the abrasive flake; and breaking the sintered abrasive flake into individual shaped abrasive particles. The method is useful to make small shaped abrasive particles having insufficient mass to be efficiently individually sintered in a rotary kiln without joining two or more of the shaped abrasive particles together.

    摘要： A cutting element for an earth-boring tool includes a substrate and volume of superabrasive material positioned on the substrate. The volume of superabrasive material includes a cutting face having at least one recess extending into the volume of superabrasive material and/or at least one protrusion extending outward from the volume of superabrasive material. The volume of superabrasive material includes a first chamfer surface having a peripheral edge and a radially innermost edge. The peripheral edge of the first chamfer surface is located proximate a cutting edge of the volume of superabrasive material. A radial width of the first chamfer surface is between about 0.002 inch and about 0.045 inch. The volume of superabrasive material also includes a second chamfer surface having a peripheral edge and a radially innermost edge. The peripheral edge of the second chamfer surface is located adjacent the radially innermost edge of the first chamfer surface.

    摘要： Aggregate abrasive grains are formed for use in the production of abrading or cutting tools by providing abrasive core particles, coating these particles with adhesive, and separately dropping the adhesive coated core particles onto a layer of abrasive peripheral particles. The method further includes covering the dropped core particles with further peripheral particles, in a way to form aggregate particles, each of which includes a core particle having peripheral particles attached to it. The adhesive includes a binding agent and a solvent for the binding agent. Finally, the aggregate particles are consolidated by causing the solvent to evaporate, i.e. by letting the adhesive set.

    摘要： A skate sharpening apparatus is disclosed having top surface (20) and a grinding disc (21) rotatable about a vertical axis above the surface. A bearing body (23, 28) having a free slide support (23) and a blocking section (28) is secured to the surface (20) slidably supports a guide bar (24). The blocking section (28) can be selectively fixed to or released from the guide bar. It is connected to the support (23) by an adjusting device moving the section (28) relative to the support (23) in fine increments. The front end (24b) of the guide bar (24) carries a pivot (34) supporting a lateral arm (35) for swinging about a horizontal swing axis (34a). The free end (36) of the lateral arm (35) carries a dressing tool (37, 37a) with rearwards directed dressing tip. The tool is slidable but can be fixed relative to the free end (36). The calibration of the desired radius of dressing the disc (21) is effected by abutting the dressing tip (38) against the disc (21) while the tip (38) coincides with the swing axis (34a) and then sliding the guide bar (24) by a distance corresponding to the desired radius and then fixing again the tool (37) to the free end (36). A digital or mechanical scale (27) at the support (23) is used in this adjustment. The invention presents an improved dressing tool where the measuring and adjusting elements are removed from the area where the debris released by the dressing might soil them. The caliration of the dressing radius is simpler than in previously known devices.

    摘要： An abrasive compact is made by a method comprising the steps of providing a circular cylindrical substrate having an upper with a non-circular recess therein defined by non-intersecting side walls. The recess is filled with diamond grains and is positioned in a press. The substrate and diamond grains are subjected to high temperature and pressure conditions in the press to sinter the diamond grains and bond the sintered diamond grains to the substrate in the form of a non-circular diamond layer. The portions of the substrate not covered by the diamond layer are removed.

    摘要： In one embodiment, a compact for tools, such as cutting, drilling and shaping tools, consists essentially of self-bonded abrasive particles. The bonded particles define a substantially continuous interconnected network of pores, dispersed throughout the compact. The method for making such a compact comprises the steps of bonding a mass of abrasive particles, aided by a sintering aid material, under high temperatures and pressures (HP/HT) to form an abrasive body comprised of said particles in a self-bonded form and said material infiltrated throughout the body. The body is then treated to remove substantially all infiltrated material, thereby to produce a compact consisting essentially of the self-bonded abrasive particles. In another embodiment, a composite compact which is made in a similar manner to the first embodiment consists essentially of a layer of self-bonded abrasive particle and a substrate layer (preferably of cemented carbide) bonded to the abrasive particle layer.
