Abstract
A coated abrasive product includes a particulate material containing green, unfired abrasive aggregates having a generally spheroidal or toroidal shape, the aggregates formed from a composition comprising abrasive grit particles and a nanoparticle binder. Free abrasive products, bonded abrasive products, and the particulate material also contain aggregates.

A method for forming abrasive particulate material comprising:
- forming a slurry comprising a liquid carrier, abrasive grit particles and a nanoparticle binder;
- and
- spray drying the slurry to form green, unfired aggregates containing the abrasive grit particles and the nanoparticle binder;
- and
- classifying the aggregates for use in an abrasive product.
44-49. (canceled)
A method for machining a workpiece, comprising:
- providing a workpiece having an initial surface roughness Rai;
- abrading the workpiece with a single abrasive product to remove material from the workpiece, whereby the workpiece has a final surface roughness Raf and Raf is not greater than 0.2 Rai, the final surface roughness being achieved with said single product without use of another abrasive product.
