Abrasive for the production of a grinding tool, grinding tool and method for operating a grinding tool of this type

Abstract

A grinding tool ( 1 ) has a replaceable abrasive ( 4 ). A grinding layer ( 9 ) of the abrasive ( 4 ) faces a drive shaft ( 2 ) of the grinding tool ( 1 ). This enables a grinding of a workpiece (W) while exerting a tensile force (F). Surface areas (O) of the workpiece (W) facing away from a processor may thus be processed easily and flexibly.

1 . An abrasive for the production of a grinding tool comprising
 a grinding layer ( 9 ) for grinding a workpiece (W), and   a connecting element ( 13 ) for connecting to an abrasive holder ( 3 ), characterized in that   
       the grinding layer ( 9 ) and the connecting element ( 13 ) are arranged on a common side (S 1 ) for grinding while exerting a tensile force (F). 
     
     
         2 . An abrasive according to  claim 1 , characterized 
       by a supporting body ( 8 ) on which the grinding layer ( 9 ) and the connecting element ( 13 ) are arranged. 
     
     
         3 . An abrasive according to  claim 1  or  2 , characterized in that 
       the grinding layer ( 9 ) is attached directly to a supporting body ( 8 ) by means of an adhesive ( 10 ). 
     
     
         4 . An abrasive according to at least one of the preceding claims, characterized in that 
       the grinding layer ( 9 ) is configured to be curved. 
     
     
         5 . An abrasive according to at least one of the preceding claims, characterized by a second grinding layer ( 17 ) which is arranged on the supporting body ( 8 ) and is opposite the first grinding layer ( 9 ). 
     
     
         6 . An abrasive according to at least one of the preceding claims, characterized in that 
       the grinding layer ( 9 ) comprises abrasive grains ( 11 ). 
     
     
         7 . An abrasive according to at least one of the preceding claims, characterized in that 
       the connecting element ( 13 ) is designed as a rotary connecting element. 
     
     
         8 . A grinding tool comprising
 a drive shaft ( 2 ) for driving the grinding tool ( 1 ) in rotation,   an abrasive holder ( 3 ) arranged on the drive shaft ( 2 ), and   an abrasive ( 4 ) replaceably arranged on the abrasive holder ( 3 ), with a grinding layer ( 9 ),   
       characterized in that 
       the grinding layer ( 9 ) faces the drive shaft ( 2 ) for grinding while exerting a tensile force (F). 
     
     
         9 . A grinding tool according to  claim 8 , characterized in that 
       the abrasive ( 4 ) comprises a connecting element ( 13 ) for connecting to the abrasive holder ( 3 ). 
     
     
         10 . A grinding tool according to  claim 9 , characterized in that 
       the abrasive holder ( 3 ) comprises a counter-connecting element ( 7 ) for connecting to the connecting element ( 13 ). 
     
     
         11 . A grinding tool according to at least one of  claims 8  to  10 , characterized in that the abrasive ( 4 ) comprises a supporting body ( 8 ) on which the grinding layer ( 9 ) and/or a connecting element ( 13 ) are arranged. 
     
     
         12 . A grinding tool according to at least one of  claims 8  to  11 , characterized in that 
       the abrasive holder ( 3 ) for supporting the abrasive ( 4 ) is arranged at least partially on a side (S 2 ) of the abrasive ( 4 ) facing away from the drive shaft ( 2 ). 
     
     
         13 . A grinding tool according to at least one of  claims 8  to  12 , characterized in that the abrasive holder ( 3 ) comprises a first holder component ( 20 ) and a second holder component ( 21 ), between which the abrasive ( 4 ) is arranged. 
     
     
         14 . A method for operating a grinding tool comprising the steps of:
 providing a grinding tool ( 1 ) according to at least one of  claims 8  to  13 , and   grinding a workpiece (W) by means of the grinding layer ( 9 ) while exerting a tensile force (F).
