<p>THE PRESENT INVENTION RELATES GENERALLY TO ABRASIVE STONE PADS FOR USE IN PROCESSING WORKPIECE SURFACES. THE ABRASIVE STONES GENERALLY ARE PRODUCED BY COMBINING A PHENOLIC RESIN MIXTURE WITH A DILUENT AND THEN INJECTING MICROBALLOON STRUCTURE INTO THE RESIN/DILUENT MIXTURE TO CREATE A POROUS SOLUTION. THE DILUENT IS INITIALLY BALL MILLED WITH AN ABRASIVE IN A TUMBLER TO ELIMINATE THE AGGLOMERATES AND IS THEN ADDED TO A RESIN MONOMER. A SUITABLE CATALYST IS ADDED TO THE MIXTURE TO CREATE A CHEMICAL REACTION, FURTHER INCREASING THE POROCITY OF THE SUBSTANCE. THE MIXTURE IS POURED INTO MOLDS AND WITH THROUGH A FILTER OR FRIT PLATE TO REMOVE EXCESS RESIN AND DILUENT. FINALLY, THE MIXTURE IS CURED, CREATING ABRASIVE STONES HAVING A UNIFORM SURFACE AND BULK STRUCTURE WITH A UNIFORM HARDNESS,SUITABLE FOR WORKPIECE GRINDING.</p> |
