Abstract: Provided is a veined end mill tool blank including a body having at least one cutting edge formed of a veined superabrasive material. An anchoring substrate supports the superabrasive material, the substrate including tungsten carbide (WC). An interface integrally joins the veined superabrasive material with the substrate. For each cutting edge, the tool blank is provided with a slot having a curved surface sintered with the superabrasive material. A locator notch is carved on the veined end mill tool blank relative to the veined superabrasive material as a reference point to aid in locating the superabrasive material on the tool blank. The locator notch engraved on the veined end mill tool blank indicates the location of the superabrasive material on the tool blank, thereby eliminating the need for manually locating coordinates of the superabrasive material during a grinding process by a tool fabricator to achieve a precise grinding.

Abstract: Provided are bearing assemblies including one or more substrate assemblies, such as thrust bearing assemblies. The substrate assemblies include a bearing element fixed to a substrate. The bearing elements are formed from a thermally stable material such as a ceramic-bonded diamond composite. Methods for manufacturing the bearing assemblies are also provided.

Abstract: A method for forming a polycrystalline diamond compact (PDC) includes treating a carbide substrate having a cobalt content therein with an acid, e.g., aqua regia, to remove cobalt from a surface portion of the carbide substrate; disposing diamond crystals on the treated carbide substrate; disposing a sweep material on the diamond crystals on a surface of the diamond opposite the carbide substrate; and applying high temperature and pressure to the carbide substrate, the diamond crystals and the sweep material such that the diamond crystals are sintered into a polycrystalline diamond attached to the carbide substrate to form the polycrystalline diamond compact.

Abstract: A blank for use in forming a machining tool having a body with at least one end face and at least two recesses formed in the end face including a first recess wherein the first recess extends from the end face at an angle of about 15° to about 60° and a second recess continuing from the first recess extending from the end face at an angle of about 40° to about 90°.
