Continuous grinding machine for machining a level workpiece surface

Abstract

The subject matter of the invention is a continuous grinding machine for machining a level workpiece surface with at least two grinding tools ( 16 ) rotating about a vertical axis ( 24 ), each grinding tool ( 16 ) including a spindle ( 18 ) rotating about the vertical axis ( 24 ) and a disc grinder ( 20 ) mounted thereon, said at least two grinding tools ( 16 ) being disposed in one row across the feed direction of the workpiece ( 10, 12 ), and at least one disc grinder ( 20 ) being retained off center on the spindle ( 18 ) of concern.

1 . A continuous grinding machine for machining a level workpiece surface with at least two grinding tools ( 16 ) rotating about a vertical axis ( 24 ), each grinding tool ( 16 ) including a spindle ( 18 ) rotating about the vertical axis ( 24 ) and a disc grinder ( 20 ) mounted thereon, and said at least two grinding tools ( 16 ) being disposed in one row across the feed direction of the workpiece ( 10 ,  12 ), 
 characterized in that at least one disc grinder ( 20 ) is retained off center on the spindle ( 18 ) of concern.    
   
   
       2 . The continuous grinding machine as set forth in  claim 1 , 
 characterized in that the distance between neighboring vertical axes ( 24 ) is smaller than the diameter of the circle of rotation ( 26 ) of the disc grinder ( 20 ).    
   
   
       3 . The continuous grinding machine as set forth in  claim 1 , 
 characterized in that neighboring disc grinders ( 20 ) are retained at the same distance from the center on their spindles ( 18 ) so that the grinding tools ( 16 ) rotate off center at the same pace.    
   
   
       4 . The continuous grinding machine as set forth in  claim 1 , 
 characterized in that neighboring grinding tools ( 16 ) rotate in the same direction of rotation.    
   
   
       5 . The continuous grinding machine as set forth in  claim 1 , 
 characterized in that the disc grinder ( 20 ) is mounted about 0.5 cm to 5 cm, preferably between 1 cm and 2 cm, off center on the spindle ( 18 ).    
   
   
       6 . The continuous grinding machine as set forth in  claim 1 , 
 characterized in that neighboring grinding tools ( 16 ) are joined together by means of a belt ( 32 ), a toothed belt more specifically.    
   
   
       7 . The continuous grinding machine as set forth in  claim 1 , 
 characterized in that the disc grinder is configured to be ellipsoidal, rectangular or star-shaped.    
   
   
       8 . The continuous grinding machine as set forth in  claim 1 , 
 characterized by a second row of grinding tools, the grinding tools of the second row being offset with respect to the grinding tools of the first row in such a manner that the grinding tools are staggered.
