Abstract
Abstract The invention provides a process of making an abrasive article whereby abrasive particles or a mixture of abrasive particles and filler particles are secured to a form by a layer of adhesive and the layer of adhesive is dissolved prior to securing the abrasive particles or the mixture of abrasive particles and filler particles to the form by a metallic bond. This is achieved by packing the form tightly in a container with packing particles prior to dissolving the adhesive.
