Abstract
A cutter holder has two limbs extending at an angle to each other. A cutter is mounted on one side of the cutter holder. An opposite side of the cutter holder has a prism-shaped cavity defined thereon. The cavity has a V-shape cross-section having a recessed groove at a base of the V-shape. A center line of the recessed groove is laterally offset from a center line of the cutter holder.
Claims10
A cutting tool apparatus for processing plant or mineral materials, comprising:
- a cutter holder having two limbs extending away from each other at an angle along respective limb lengths;
- at least one cutter mounted on a first side of at least one of the limbs, the cutter being made of a hard material harder than the cutter holder;
- and
- wherein the cutter holder has a prism-shaped cavity formed therein on a second side of the limbs opposite the at least one cutter, the prism-shaped cavity having a cross-section having a V-shape defined by two contact surfaces, with a base of the V-shape having a recessed groove defined in each limb, each recessed groove following the length of its respective limb, and each recessed groove intersecting the two contact surfaces and separating the two contact surfaces and being recessed from the two contact surfaces toward the first side;
- each limb has a limb center line parallel to its limb length and lying within the recessed groove;
- and
- each recessed groove of the prism-shaped cavity has a recessed groove center line offset from the limb center line of its respective limb.
4 more elements
A cutting tool apparatus, comprising:
- a cutter holder having first and second limbs extending away from each other at an obtuse angle, the limbs defining a cutter support side within the obtuse angle and a mounting side opposite from the cutter support side;
- at least one cutter attached to the cutter support side;
- and
- wherein the first and second limbs have a mounting cavity defined in the mounting side of the cutter holder;
- wherein the mounting cavity has a cross-sectional shape perpendicular to a length of each limb, the cross-sectional shape being defined by two contact surfaces separated by a groove intersecting the two contact surfaces and recessed from the two contact surfaces toward the cutter support side, the two contact surfaces tapered toward each other and toward the recessed groove;
- and
- wherein the recessed groove has first and second groove base portions extending along the first and second limbs, respectively, the first and second groove base portions defining the obtuse angle between the first and second limbs;
- and
- wherein the recessed groove is laterally offset toward one of the two contact surfaces so that one of the two contact surfaces has a cross-sectional length greater than the other of the two contact surfaces.
