Abstract
Embodiments of the invention are directed to cutting tool assemblies, cutting tool mounting assemblies, material-removing machines that include cutting tool assemblies and/or cutting tool mounting assemblies, and methods of use and operation thereof. In some embodiments, the various assemblies described herein may be used in material-removing machines that may remove target material.
Claims21
A cutting tool assembly configured for attachment to a base body on a rotatable assembly of a material-removal machine, the base body having a tool recess and an outer upper surface outside the tool recess, the cutting tool assembly comprising:
- a support block including:
- an elongated mounting shank having a vertical axis sized and configured to be secured at least partially within the tool recess of the base body;
- and
- an upper portion configured to be positioned outside the base body when the elongated mounting shank is secured at least partially within the tool recess of the base body, the upper portion including two opposing shoulders extending away from the vertical axis beyond the elongated shank in corresponding opposing lateral directions and positioned to contact the outer upper surface of the base body when the elongated mounting shank is secured at least partially within the base body;
- a bolster body secured to the support block, the bolster body extending away from the vertical axis in a direction that is generally non-parallel to the opposing lateral directions;
- and
- a cutting element secured to and positioned at least partially within the bolster body, the cutting element having a superhard working surface that includes a superhard material, and the bolster body being sized and configured to protect at least a portion of the cutting element from at least one of erosion or wear during operation of the cutting tool assembly.

A cutting tool mounting assembly, comprising:
- a base body sized and configured to be mounted to a material-removal machine, the base body including a tool recess and an outer upper surface outside of the tool recess;
- and
- a cutting tool assembly mounted to the base body, the cutting tool assembly including:
- a support block including:
- an elongated mounting shank having a vertical axis and positioned at least partially in the tool recess of the base body;
- and
- an upper portion positioned outside the base body, the upper portion including two opposing shoulders extending away from the vertical axis beyond the elongated shank in corresponding opposing lateral directions and contacting the outer upper surface of the base body;
- a bolster body secured to the support block, the bolster body extending away from the vertical axis in a direction that is generally non-parallel to the opposing lateral direction;
- and
- a cutting element secured to and positioned at least partially within the bolster body, the cutting element having a superhard working surface that includes a superhard material, and the bolster body being sized and configured to protect at least a portion of the cutting element from at least one of wear or erosion during operation of the cutting tool assembly.
7 more elements
A rotary assembly, comprising:
- a rotary body including an outer surface;
- and
- a plurality of cutting tool mounting assemblies mounted to the rotary body, each of the plurality of cutting tool mounting assemblies including:
- a base body mounted to the outer surface of the rotary body, the base body including a tool recess and an outer upper surface outside the tool recess;
- and
- a cutting tool assembly mounted to the base body, the cutting tool assembly including:
- a support block including an elongated mounting shank positioned in the tool recess of the base body and an upper portion positioned outside the base body, the elongated mounting shank having a vertical axis and the upper portion including two opposing shoulders extending away from the vertical axis beyond the elongated shank in corresponding opposing lateral directions and contacting the outer upper surface of the base body;
- a bolster body secured to the support block, the bolster body extending away from the vertical axis in a direction that is generally non-parallel to the opposing lateral directions;
- and
- a cutting element secured to and positioned at least partially within the bolster body, the cutting element having a superhard working surface that includes a superhard material, and the bolster body being sized and configured to protect at least a portion of the cutting element from at least one of wear or erosion during operation of the cutting tool assembly.
