摘要： A degradation assembly comprises a rotary portion and a stationary portion. The rotary portion includes a cemented metal bolster bonded to a tip. The tip comprises a symmetric, substantially conically shaped tip formed of diamond and a cemented metal carbide substrate. The stationary portion comprises a holder configured to be coupled to a block mounted to a driving mechanism. A compressible element is disposed intermediate, or between, and in mechanical contact with both the rotary portion and the stationary portion.

摘要： A degradation assembly comprises a rotary portion and a stationary portion. The rotary portion includes a cemented metal bolster bonded to a tip. The tip comprises a asymmetric, substantially conically shaped tip formed of diamond and a cemented metal carbide substrate. The stationary portion comprises a holder configured to be coupled to a block mounted to a driving mechanism. A compressible element is disposed between and in mechanical contact with both the rotary portion and the stationary portion.

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： In one aspect of the present invention, the present invention is a system for removing aggregate from a paved surface. The system includes a motorized vehicle with a degradation drum that is connected to the underside of the vehicle. The degradation drum is enclosed by a milling chamber. The milling chamber is defined by having a plurality of plates, including a moldboard positioned rearward of the milling drum. The moldboard comprises an end that is disposed opposite the underside. The end comprises a section that is proximate the milling drum.

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.
