Grinding body

Abstract

A grinding body ( 1 ), which consists of a support material ( 5 ) and an abrasive ( 2 ) adhesively applied thereto, is formed such that the grinding body ( 1 ) has an abrasive-free rim that laterally adjoins the active region of the abrasive ( 2 ).

1 . A grinding body ( 1 ), consisting of a carrier material ( 5 ) and an abrasive ( 2 ) adhesively applied thereto, characterized in that the grinding body ( 1 ) has an abrasive-free edge, which laterally delimits the active region of the abrasive ( 2 ). 
     
     
         2 . The grinding body according to  claim 1 , characterized in that the abrasive-free edge is formed by an applied material ( 3 ), which smooths the structure of the abrasive ( 2 ). 
     
     
         3 . The grinding body ( 1 ) according to  claim 2 , characterized in that it is a mineral material or a polymer material ( 3 ). 
     
     
         4 . The grinding body ( 1 ) according to  claim 3 , characterized in that plaster is provided as a mineral material ( 3 ). 
     
     
         5 . The grinding body ( 1 ) according to  claim 3 , characterized in that a two-component lacquer is provided as a polymer material ( 3 ). 
     
     
         6 . The grinding body ( 1 ) according to  claim 3 , characterized in that a two-component polyester resin is provided as a polymer material ( 3 ). 
     
     
         7 . The grinding body ( 1 ) according to  claim 2 , characterized in that the material ( 3 ) which smooths the structure of the abrasive ( 2 ) is applied in a thickness of 30 to 40 μm. 
     
     
         8 . The grinding body ( 1 ) according to  claim 2 , characterized in that the material ( 3 ) which smooths the structure of the abrasive ( 2 ) is applied by screen printing, pad printing, spray lacquering, stamping, brush application, immersion, or gluing. 
     
     
         9 . The grinding body ( 1 ) according to  claim 1 , characterized in that a fabric, paper, a plastic film, or a carrier plate is used as the carrier material ( 5 ). 
     
     
         10 . The grinding body ( 1 ) according to  claim 1 , characterized in that the abrasive ( 2 ) adheres to the carrier material ( 5 ) by way of a binding agent ( 4 ). 
     
     
         11 . The grinding body ( 1 ) according to  claim 1 , characterized in that a connecting means ( 6 ) for connecting the grinding body ( 1 ) to a grinding device is applied on the side of the carrier material ( 5 ) facing away from the abrasive ( 2 ). 
     
     
         12 . The grinding body ( 1 ) according to  claim 1 , characterized in that the grain of the abrasive ( 2 ) is in a range between 2500 and 7000, preferably at 3000. 
     
     
         13 . The grinding body ( 1 ) according to  claim 1 , characterized in that the carrier material ( 5 ) has a thickness between 30 μm and 70 μm, preferably 50 μm.
