Abstract

Flexible abrasive articles and related methods are presented.

Claims

exact text as granted — not AI-modified
1 . A process comprising:
 obtaining:   a sheet comprising a first side, a second, side, and a plurality of recesses, wherein the sheet has a thickness between about 1 mil and about 50 mil, a Brinnell hardness between about 50 HB and about 2500 HB, and a Young's Modulus between about 60 GPa and about 350 GPa; and   abrasive grains suspended in a solution, wherein the abrasive grains have a grit size between about U.S. mesh 20 and about U.S. mesh 600 and a Vickers hardness between about 500 kg/mm 2  and about 10,000 kg/mm 2 ;   submerging the sheet in the solution; and   depositing the abrasive grains on the first side of the sheet.   
     
     
         2 . The process of  claim 1 , wherein the depositing further comprises applying an electric current to the solution to provide nickel plating, chromium plating, iron plating, silver plating, copper plating, tin plating, zinc plating, aluminum plating, tungsten plating, cadmium plating, or bismuth plating. 
     
     
         3 . The process of  claim 1 , wherein the recesses are circular, elliptical, or polygonal. 
     
     
         4 . The process of  claim 1 , wherein the sheet comprises steel, copper or aluminum. 
     
     
         5 . The process of  claim 1 , wherein the abrasive grains comprise diamond, aluminum oxide, silicon carbide, tungsten carbide, zirconium oxide, or garnet. 
     
     
         6 . The process of  claim 1 , further comprising cutting a disk from the sheet, wherein the disk comprises a first face and a second face. 
     
     
         7 . The process of  claim 6 , further comprising coupling a backsheet to the second face of the disk, wherein the backsheet comprises a polymer resin or a metal wire mesh. 
     
     
         8 . The process of  claim 1 , wherein the disk has a major dimension between about 0.5 inch and about 8 inches. 
     
     
         9 . An apparatus comprising:
 a sheet comprising a first side, a second side, and plurality of recesses, wherein the sheet has a thickness between about  1  mil and about  50  mil, a Brinnell hardness between about  50  HB and about 2500 HB, and a Young's Modulus between about 60 GPa and about 350 GPa; and   abrasive grains deposited on the first side of the sheet, wherein the abrasive grains have a grit size between about U.S. mesh 20 and about U.S. mesh 600, and a Vickers hardness between about 500 kg/mm 2  and about 10,000 kg/mm 2 .   
     
     
         10 . The apparatus of  claim 9 , wherein the recesses are circular, elliptical, or polygonal. 
     
     
         11 . The apparatus of  claim 9 , wherein the sheet comprises steel, copper or aluminum, 
     
     
         12 . The apparatus of  claim 9 , wherein the abrasive grains comprise diamond, aluminum oxide, silicon carbide, tungsten carbide, zirconium oxide, or garnet. 
     
     
         13 . The apparatus of  claim 9 , wherein the sheet is electrolytically plated with nickel plating, chromium plating, iron plating, silver plating, copper plating, tin plating, zinc plating, aluminum plating, tungsten plating, cadmium plating, or bismuth plating. 
     
     
         14 . The apparatus of  claim 9 , further comprising coupling a backsheet to the second side of the disk, wherein the backsheet comprises a polymer resin or a metal wire mesh. 
     
     
         15 . The process of  claim 9 , wherein the disk has a major dimension between about 0.5 inch and about 8 inches. 
     
     
         16 . The apparatus of  claim 9 , further comprising a spindle coupled to the second face. 
     
     
         17 . The apparatus of  claim 16 , where the spindle is a quick-lock spindle. 
     
     
         18 . The apparatus of  claim 16 , further comprising a backsheet coupled to the spindle and the second face. 
     
     
         19 . The apparatus of  claim 18 , wherein the backsheet comprises a polymer resin or a metal wire mesh. 
     
     
         20 . The apparatus of  claim 17 , further comprising a backsheet coupled to the quick-lock spindle and the second face.
