Grinding machine

Abstract

The present invention comprises a grinding machine ( 1 ) for grinding a surface of a workpiece ( 6 ), wherein the grinding machine ( 1 ) has at least one abrasive holder ( 2 ), on which at least one abrasive ( 4 ) is arranged, and at least one drive device for moving the abrasive holder ( 2 ), wherein the drive device has at least one drive shaft ( 12 ), on which an eccentric element ( 16 ) is arranged and which can be rotated about an axis of rotation ( 18 ), wherein the eccentric element ( 16 ) is arranged on the abrasive holder ( 2 ) at a distance from the axis of rotation ( 18 ), wherein it is possible to adjust the distance.

1 . A grinding machine for grinding a surface of a workpiece, comprising:
 at least one abrasive holder on which at least one abrasive is arranged; and   at least one drive device for moving the at least one abrasive holder, wherein the at least one drive device has at least one drive shaft on which at least one eccentric element is arranged and which can be rotated about an axis of rotation,   wherein the at least one eccentric element is arranged on the at least one abrasive holder at a distance from the axis of rotation,   wherein the distance from the axis of rotation is adjustable.   
     
     
         2 . The grinding machine according to  claim 1 , wherein the at least one eccentric element is adjustable in length. 
     
     
         3 . The grinding machine according to  claim 1 , wherein the at least one eccentric element is arranged in a releasable manner on the at least one drive shaft and is arrangeable at different positions on the at least one drive shaft. 
     
     
         4 . The grinding machine according to  claim 3 , further comprising on the at least one eccentric element and on the at least one drive shaft mutually corresponding form-fitting elements which allow the at least one eccentric element to be arranged in a form-fitting manner on the at least one drive shaft. 
     
     
         5 . The grinding machine according to  claim 4 , wherein the mutually corresponding form-fitting elements have a guide track in or on which one of the mutually corresponding form-fitting elements is arranged in a displaceable manner. 
     
     
         6 . The grinding machine according to  claim 5 , wherein the one of the mutually corresponding form-fitting elements that is displaceable in or on the guide track is selectively clampable at different positions in or on the guide track. 
     
     
         7 . The grinding machine according to  claim 1  wherein the at least one drive device has at least two drive shafts, and wherein an eccentric element is arranged on each of the at least two drive shafts. 
     
     
         8 . The grinding machine according to  claim 1  further comprising at least one pressure-exerting element for subjecting at least part of the at least one abrasive to pressure, wherein the at least one pressure-exerting element is movable relative to the at least one abrasive. 
     
     
         9 . The grinding machine according to  claim 8 , wherein the at least one pressure-exerting element has a surface which has a structure. 
     
     
         10 . The grinding machine according to  claim 9 , wherein the surface of the at least one pressure-exerting element having the structure is directed toward the at least one abrasive.
