摘要： A diamond coated elongate rotary cutting member and method of making the same. The cutting member (40) includes an axially forward cutting surface (42), a flute (50) and a fluted land (52). The cutting member comprises a substrate with hard grains bonded together with a metallic binder. The substrate has a first substrate region that presents an irregular surface so as to define the axially forward cutting surface (24, 26, 28) and the fluted land (52). The first substrate region contains relatively large hard grains near the surface thereof that are larger in size than the hard grains in the interior of the substrate. A diamond coating is on the surface of the first substrate region. The substrate has a second substrate region that defines the flute.

摘要： A method of, and apparatus for, treating an elongate rotary tool (22) that presents a sharp cutting edge (30) are described. The method includes the steps of emitting under pressure from a nozzle (60) an abrasive fluid stream comprising an abrasive grit entrained in a fluid; and impinging the abrasive fluid stream against the sharp cutting edge (30) of the elongate rotary tool (22) for a preselected time so as to transform the sharp cutting edge (30) into a relatively uniformly honed edge. The apparatus (50) includes a rotatable fixture (54) that releasably holds the elongate rotary tool (22). A nozzle (60) that emits under pressure an abrasive steam. The nozzle (60) and the elongate rotary tool (22) are relatively moveable so that the abrasive stream impinges the entire length of the sharp cutting edge (30).

摘要： A rotating tool (10) mateable with the spindle of a machine tool for high speed rotation is disclosed. The tool is comprised of a shank (12) and a disk (14). The disk (14) has attached to its periphery cutting inserts (20). These inserts (20) may be attached directly to recesses in the disk or to lugs (22) protruding from the disk (14). If the inserts are attached to lugs (22), then the disk (14) will further have opposing counterweight lugs (24) protruding from the disk (14) in an opposite direction. A band (34) of high tenacity material extends around the disk (14) to restrain radial expansion. Additionally, the disk (14) may be encompassed in a restraining material to restrain any disk parts that may separate from the disk body.

摘要： A cutting tool assembly (1) clamping mechanism (5) which secures a cutting insert (3) for performing cutoff, grooving, slotting, and profiling operations. The clamping mechanism (5) has resilient upper and lower clamping jaws (7, 9) for receiving and securing the insert (3). The cutting insert (3) has front and top faces (13, 15) that define a cutting edge (21) at an intersection thereof, a back face (25), and adjacent proximal and distal bottom faces (27, 29) contiguous with said front and back faces (13, 25) that define an angular lower seating portion (30). The lower clamping jaw (9) of the clamping mechanism (5) includes proximal and distal pocket surfaces (59, 67) forming an angularly recessed jaw portion that is complementary in shape to the angular seating portion (30) of the insert (3). The distal pocket surface (67) of the lower clamping jaw (9) is oriented with the proximal pocket surface (59) to form a stop for limiting the extent that the insert (3) may be received between the clamping jaws (7, 9). This orientation further redirects a component of the cutting force (F) on the insert (3) toward the top face (15) thereof in order to wedgingly engage the top face (15) of the insert (3) against the top pocket surface (45) of the upper clamping jaws (9), thereby enhancing the clamping force that the jaws (7, 9) apply to the insert (3).

摘要： A method of heat treating a green compact having an exposed surface. The method includes the steps of: providing a green compact comprised of a hard carbide and binder; placing a powder of grain refiner on at least one portion of the exposed surface of the green compact; and heat treating the green compact and grain refiner powder so as to diffuse the grain refiner toward the center of the green compact thereby forming a peripheral zone (80) inwardly from the exposed surface in which the grain refiner was placed, and forming an interior zone (84). The peripheral zone having a grain size that is smaller than the grain size of the bulk zone.

摘要： A metal cutting tool assembly (1) having an automatically adjustable chipbreaker (23) is provided that comprises a cutting insert (11) for cutting a relatively rotating workpiece, a holder (3) for holding the insert (11), an insert driver (5) for applying a cutting force between the insert (11) and the workpiece, a chipbreaker (23) having a surface (27) that is effective in breaking chips (55, 56) of different thicknesses when positioned at different distances from the cutting edge (19) of the insert (11), and a mounting mechanism (30) for movably mounting the chipbreaker (23) onto the holder (3). The mounting mechanism (30) includes a spring (50) for automatically adjusting the distance between the chipbreaking surface (27) of the chipbreaker (23) and the cutting edge (19) of the insert (11) in response to the forces applied to the chipbreaker (23) by the metal chips (55, 56) that result from the cutting operation. The mounting mechanism (30) may allow the chipbreaker (23) to either slidably reciprocate on the holder (3) toward and away from the cutting edge (19), or to pivotally move with respect to the cutting edge (19). In both cases, the deflection of the spring (50) is proportional to the thickness of the metal chips (55, 56) engaging the chipbreaking surface (27), which in turn automatically provides the appropriate chipbreaking geometry. The inventive tool assembly allows the same chipbreaker (23) to effectively break chips (55, 56) of widely varying thicknesses which are created when the cutting insert (11) is used to make a variety of different types of cuts in a machining operation.
