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: A tool has a sintered body of diamond or diamond-like particles in a metal matrix bonded to a cemented metal carbide substrate at a non-planar interface. A working surface has at least one region fir enough away from the non-planar interface that during high pressure, high temperature processing a restricted amount of metal from the substrate reaches the region, the amount comprising 5 to 0. 1 percent of the region by volume, resulting in the region having a high density of superhard particles.
