Grinding machine

Abstract

The present invention relates to a grinding machine for grinding a surface of a workpiece, having at least one transport device for transporting a workpiece in a transport direction through the grinding machine, and at least one grinding tool ( 2 ), wherein the grinding tool ( 2 ) has at least one brush with grinding bristles, wherein the grinding machine has a leveling unit.

1 . A grinding machine for grinding a surface of a workpiece, comprising:
 at least one transport device for transporting a workpiece hi a transport direction through the grinding machine;   at least one grinding tool that has at least one brush with grinding bristles; and   a leveling unit.   
     
     
         2 . The grinding machine according to  claim 1 , wherein the leveling unit has at least one leveling tool for shortening at least some of the grinding bristles. 
     
     
         3 . The grinding machine according to  claim 2 , wherein the at least one leveling tool is arranged so as to be displaceable in a direction perpendicular to the transport direction. 
     
     
         4 . The grinding machine according to  claim 2  wherein at least one of the at least one grinding tool and the at least one leveling tool is arranged so as to be height-adjustable. 
     
     
         5 . The grinding machine according to  claim 2  further comprising a multiplicity of disk brushes which revolve along a revolving contour, and wherein the at least one leveling tool is arranged adjacent to the at least one transport device. 
     
     
         6 . The grinding machine according to  claim 2  further comprising a measuring device for measuring a length of at least some of the grinding bristles. 
     
     
         7 . The grinding machine according to  claim 6 , wherein the measuring device is designed to measure the length of the grinding bristles at different points of the at least one grinding tool, and further comprising an electrical controller designed to bring the at least one leveling tool into engagement with the grinding bristles if a length difference between different bristles exceeds a predetermined threshold value. 
     
     
         8 . The grinding machine according to  claim 7 , wherein the predetermined limit value is dependent on the length of the grinding bristles. 
     
     
         9 . The grinding machine according to  claim 1  further comprising an imbalance measuring device for measuring an imbalance of the at least one grinding tool.
