Grinding Disc And Method For Production Thereof

Abstract

A grinding disc, comprising a particularly metal grinding disc base body and abrasive grains applied to a surface of the grinding disc base body, in particular, made from cubic boron nitride is disclosed. The abrasive grains are arranged on the surface of the grinding disc base body with a defined position and defined separation to each other. A greater number of abrasive grains are arranged in given macro regions ( 18 ) of the surface of the grinding disc base body than in other given macro regions ( 19 ) of the surface.

1 - 12 . (canceled) 
     
     
         13 . A method for manufacturing a grinding disk comprising:
 providing a grinding disk base body having a surface;   providing abrasive grains;   applying the abrasive grains to the surface of the grinding disk base body in a defined position and with defined spacing to one another, at least one of the grinding disk base body and the abrasive grains being nickel-plated, the abrasive grains adhering to heated macro-areas of the surface of the grinding disk base body due to partial heating of the surface of the grinding disk base body and the application of the abrasive grains to the heated macro-areas of the surface; and   subsequent to the adhesion of the abrasive grains to the heated macro-areas of the surface of the grinding disk base body, providing a chemical or galvanic nickel-plating.   
     
     
         14 . The method as recited in  claim 13  wherein the grinding disk base body is made of metal. 
     
     
         15 . The method as recited in  claim 13  wherein the abrasive grains are made of cubic boron nitride. 
     
     
         16 . The method as recited in  claim 13  wherein the surface of the grinding disk base body is heated exclusively in the macro-areas, and that the abrasive grains are applied exclusively to the heated macro-areas of the surface of the grinding disk base body. 
     
     
         17 . The method as recited in  claim 13  wherein the heating is carried out via partial laser irradiation of the surface of the grinding disk base body. 
     
     
         18 . The method as recited in  claim 13  wherein the abrasive grains are applied to an entirety of the surface of the grinding disk base body and further comprising subsequently removing the abrasive grains from the macro-areas. 
     
     
         19 . The method as recited in  claim 18  wherein the removal of the abrasive grains from the predetermined macro-areas is carried out via partial laser irradiation of the surface of the grinding disk base body.
