Grinding wheel

Abstract

Grinding wheel for a floor grinding machine, comprising a metal wheel ( 1 ) with a first and a second flat surface. Diamond-containing grinding elements ( 11, 12 ) are arranged on the first flat surface. Grinding elements ( 11, 12 ), preferably diamond-containing, are also arranged on the second flat surface of the wheel ( 1 ).

       2 . Grinding wheel according to  claim 1 , wherein the grinding elements on the first and second flat surfaces of the wheel have different grinding actions.  
   
   
       3 . Grinding wheel according to  claim 1 , wherein the grinding elements arranged on the second flat surface are diamond-containing.  
   
   
       4 . Grinding wheel according to  claim 1 , wherein the wheel is substantially circular.  
   
   
       5 . Grinding wheel according to  claim 1 , wherein at least some of the grinding elements are arranged at or close to the circumferential edge of the wheel.  
   
   
       6 . Grinding wheel according to  claim 1 , wherein the grinding elements are welded to the wheel.  
   
   
       7 . Grinding wheel according to  claim 1 , wherein the grinding elements are elongate in form.  
   
   
       8 . Grinding wheel according to  claim 7 , wherein at least some of the grinding elements extend substantially in the tangential direction.  
   
   
       9 . Grinding wheel according to  claim 7 , wherein at least some of the grinding elements extend substantially in the radial direction.  
   
   
       10 . Grinding wheel according to  claim 7 , wherein at least some of the grinding elements extend substantially in the tangential direction and at least some of the grinding elements extend substantially in the radial direction, wherein the grinding elements which extend in the tangential direction and the grinding elements which extend in the radial direction are arranged alternately in the vicinity of the circumferential edge of the grinding wheel.  
   
   
       11 . Grinding wheel according to  claim 8 , wherein the tangentially extending grinding elements are curved.  
   
   
       12 . Grinding wheel according to  claim 9 , wherein the radially extending grinding elements are curved.  
   
   
       13 . Grinding wheel according to  claim 1 , wherein all the grinding elements are of the same shape.  
   
   
       14 . Grinding wheel according to  claim 1 , wherein the diamond-containing grinding elements comprise a diamond-steel compound.  
   
   
       15 . Grinding wheel according to  claim 1 , wherein the wheel is provided with a central opening for coupling to a drive shaft of the grinding machine.  
   
   
       16 . Grinding wheel according to  claim 15 , wherein the central opening is delimited by an edge which is wavy in form.  
   
   
       17 . Grinding wheel according to  claim 15 , wherein the central opening is formed by laser cutting.  
   
   
       18 . Grinding wheel according to  claim 1 , wherein securing holes for securing means to fit through are arranged in the wheel, the holes being formed in such a manner that the head of the securing means, in the fitted state, is recessed below the level of the surface of the wheel.
