An additive impregnated abrasive article and method for fabricating the same is provided. The method includes providing an abrasive article having a pore structure, dissolving an additive in a supercritical fluid, and exposing the abrasive article to the additive-laden supercritical fluid, so that the fluid disperses through the pore structure. The supercritical fluid is then brought to below its critical point for a period of time sufficient to dissociate the additive from the fluid, so that the additive is deposited within the pore structure of the abrasive article.

Impregnation of grinding wheels using supercritical fluids

A method is provided for fabricating an abrasive article having porosity. The method includes blending a mixture of abrasive grain, bond material, and pore inducer, in which the pore inducer is soluble in a supercritical fluid, and the abrasive grain and bond material are substantially insoluble in the supercritical fluid. The mixture is pressed into an abrasive laden composite and exposed to the supercritical fluid for a period of time suitable to dissolve at least a portion of the pore inducer. The composite is thermally processed.

Supercritical fluid extraction

The invention provides coated abrasives with an engineered surface that releases a pleasing fragrance when used.

Scented engineered abrasives

The invention provides a useful tool for advising customers for abrasive tools on the selection of optimum grinding conditions for the use of a specific tool wherein the tool is in the form of a performance map generated from a plurality of data points obtained by measuring performance for a plurality of combinations of the two key grinding process variables.

Process for determining optimum grinding conditions

An optical polishing tool comprises alpha alumina and ceria components in relative weight proportions of from 30:70 to 70:30 dispersed in a resin binder. Particularly preferred are coated abrasives. Such coated abrasives produce an improved optical polishing performance.
