摘要: In one aspect of the invention, a high impact resistant tool includes a superhard material bonded to a cemented metal carbide substrate at a non-planar interface. The superhard material has a substantially pointed geometry with a sharp apex having a radius of curvature of 0.050 to 0.125 inches. The superhard material also has a thickness of 0.100 to 0.500 inches thickness from the apex to a central region of the cemented metal carbide substrate.

摘要: In one aspect of the invention, a pick comprises a carbide bolster disposed intermediate an impact tip and a shank assembly. The impact tip comprises a superhard material bonded to a carbide substrate, and the tip is bonded to the bolster opposing a base of the bolster. The shank assembly comprises a central axis, a first end that protrudes into a cavity formed in the base of the bolster, and also an inducible attachment mechanism disposed proximate the first end. The inducible attachment mechanism is adapted to attach the shank assembly to the carbide bolster and restrict movement of the shank assembly with respect to the carbide bolster. The attachment mechanism may restrict movement of the shank assembly in a direction parallel to the central axis.

摘要: In one aspect of the present invention, a tool assembly comprises a rotary portion and a stationary portion. The rotary portion comprises a bolster bonded to a diamond symmetric, substantially conically shaped tip. The stationary portion comprises a block mounted to a driving mechanism. A compressible element is disposed intermediate and in mechanical contact with both the rotary and stationary portions. The compressible element is compressed sufficiently to restrict free rotation during a degradation operation.

摘要: In one aspect of the present invention, a pick assembly is configured that comprises a pick shank configured to be press fit directly within a bore of a block. The pick shank comprises an inside and outside surface. The pick comprises a pick head opposite the shank. The shank comprises at least one longitudinal recess extending towards the pick head along the shank from a distal end of the shank. The recess allows the shank to resiliently collapse upon insertion into the bore while maintaining a press fit between the bore and the shank.

摘要: A degradation assembly, comprising a platform comprising a surface. A plurality of picks each comprising a hard tip and a shank may be mounted on the surface. A plurality of sensors may also be disposed within the platform such that they can measure impacts on at least one of the picks. The sensors may be in communication with a processor. The degradation assembly may be capable of detecting and determining the location of a selected pick measuring impacts on at least one pick with at least one sensor, detecting a variation on the at least one pick with the at least one sensor, and determining a location of the at least one pick with more than one of the sensors.
