Abstract: A vitrified superabrasive product includes a superabrasive component and a vitrified bond component in which the superabrasive component is dispersed. The vitrified bond includes an oxide of a lanthanoid. Additionally, the vitrified bond component defines pores that can be essentially all less than 800 µm in diameter. Seventy percent of the pores are in a range of between about 40 µm and about 500 µm and have an average aspect ratio less than about 2. The porosity is in a range of between about 50% and about 90% of the total volume of the superabrasive product.

Abstract: A superabrasive product, such as a superabrasive tool, includes a superabrasive grain component and a porous continuous phase that includes a thermoplastic polymer component in which the superabrasive grain component is distributed. A superabrasive product precursor to the superabrasive product includes a superabrasive grain component, a bond component and a polymer blowing agent of encapsulated gas. A method of forming a superabrasive product includes combining a superabrasive, a bond component and a polymer blowing agent of encapsulated gas to form, for example, a superabrasive product precursor. The combined superabrasive, bond component and polymer blowing agent of encapsulated gas are heated to a temperature and for a period of time that causes release of at least a portion of the gas from encapsulation within the blowing agent.

Abstract: A vitrified superabrasive product includes a superabrasive component and a vitrified bond component in which the superabrasive component is dispersed, wherein the vitrified bond component defines pores occupying greater than about 50% of the total volume of the vitrified superabrasive product. The vitrified superabrasive product can be in the form of a grinding tool, such as a grinding wheel. A superabrasive mixture includes a glass powder, a superabrasive grit, a binder and a silicon carbide. The mixture can be in the form of a green body, which is fired under an atmosphere and pressure, and at a temperature sufficient to form a porous vitrified superabrasive product.

Abstract: Abrasive tools and techniques are disclosed that can cut hard, brittle materials to relatively precise dimensions. The tools, which can include a hybrid bond of metal or metal alloy and a resin matrix together with fine abrasive grits, can be employed, for example, in mirror finish cutting applications, thereby enabling '1X' or 'single-pass' multi-function abrasive processes. The specific selection of resin and metal or metal alloy types is such that the tool is sufficiently brittle for the purpose of manufacture and durability, but ductile enough to withstand the grinding and handling stresses (an exemplary hybrid bond includes bronze and polyimide). Numerous tool types and applications will be apparent in light of this disclosure, including abrasive products for electronic device manufacturing such as thin 1A8 blades (single blade or multi-blade configuration).
