Process of manufacturing base of diamond abrasive stone

Abstract

A process for manufacturing the base of a diamond abrasive stone wherein a steel plate having a plurality of oval holes is bonded to a plastic base in a casting process so that plastic material is forced through the holes. Layers of nickel diamond material is applied to the surface of the steel plate.

1 . A process for manufacturing our abrasive stone composing the step 
 punching a plurality of holes through a flat steel palate,    applying the steel plate to plastic material,    casting the plastic material to form a base and forcing the plastic material through the plurality of holes,    grinding the surface of the steel plate,    applying flash nickel plating to the surface of the plate, and    applying multiple layers of nickel diamond material on the surface of the plate.    
     
     
         2 . The process according to  claim 1  wherein said holes are oval and external laterally across the plate in rows.  
     
     
         3 . The process according to  claim 2  wherein a portion of the steel plate is free of holes.
