    Abstract: Abrasive articles possessing a highly open (porous) structure and uniform abrasive grit distribution are disclosed. The abrasive articles are fabricated using a metal matrix and the open structure is controlled with a porosity scheme, including interconnected porosity (e.g., formed by leaching dispersoid), closed porosity (e.g., induced by adding hollow micro-spheres and/or sacrificial pore-forming additives), and/or intrinsic porosity (e.g., controlled via matrix component selection to provide desired densification). In some cases, manufacturing process temperatures for achieving near full density of metal bond with fillers and abrasives are below the melting point of the filler used, although sacrificial fillers may be used as well. The abrasive articles are useful in high performance cutting and grinding operations, such as back-grinding silicon, alumina titanium carbide, and silicon carbide wafers to very fine surface finish values. Techniques of use and manufacture are also disclosed.

    Abstract: A single-use grinding tool includes a wheel portion having a profiled recess (e.g., such as a U, V, or bowl shape) extending circumferentially along the wheel portion's periphery. A multi-layered bonded abrasive (e.g., 3-dimensional matrix of abrasive grains and bond material, or multiple layers of abrasive tape) is conformably coated or otherwise applied in a uniform thickness along the profiled recess. The bonded abrasive in one particular case includes a metal bond with diamonds. However, organic, resinous, vitrified, and hybrid bonds, as well as other abrasive grit types, can be used. The wheel portion is supported by an arbor portion which may be removably coupled to the wheel portion, or formed integrally with the wheel portion. The tool is useful, for example, in edge grinding a workpiece, such as sheet glass. Methods of tool use and tool manufacture are disclosed as well.

    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).
