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 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.

摘要: In one aspect of the present invention, a high impact resistant tool has a superhard material bonded to a cemented metal carbide substrate at a non-planar interface. The cemented metal carbide substrate is bonded to a front end of a cemented metal carbide segment. A stem formed in the base end of the carbide segment opposite the front end is press fit into a bore of a steel body. The steel body is rotationally fixed to a drum adapted to rotate about its axis.
