20100064594 | ABRASIVE GRAINS HAVING UNIQUE FEATURES - An uncoated abrasive or superabrasive grain having at least one grain face including three or more features projecting from the grain face wherein the height (h) and the lateral length (l) of each feature is greater than about 0.1 micron. | 03-18-2010 |
20100194176 | RADIAL TOOL WITH SUPERHARD CUTTING SURFACE - A non-rotating mining cutter pick has a shank portion with a non-circular cross-section, a head portion including a tip region distal from the shank portion, a shoulder portion separating the shank portion from the head portion, and a cutting insert mounted at a front end of the tip region. The cutting insert includes a body formed of tungsten carbide and an element formed of a superhard material, such as PCD or other material having a prescribed knoop hardness. At least a portion of a first surface of the element is exposed on a cutting surface of the cutting insert, which improves wear properties of the mining cutter pick. The element is fused to the body of the cutting insert, preferably in a high pressure-high temperature (HPHT) process. A method of manufacture and a cutting machine incorporating the non-rotating mining cutter pick on the rotatable element are also disclosed. | 08-05-2010 |
20130167446 | CUTTER ASSEMBLY WITH AT LEAST ONE ISLAND AND A METHOD OF MANUFACTURING A CUTTER ASSEMBLY - A cutter assembly includes a substrate and at least one island.
