Grinding tool and method of manufacturing the grinding tool

Abstract

A manufacturing method for grinding tool includes following steps. Step 1 is providing a substrate. Step 2 is fixing diamond or abrasive grit in a predetermined position or base by DIAMAP (Diamond Implant Array Mapping & Arrangement Process). The last step is providing a second fixing layer onto the first fixing base and the exposed surface of the substrate. The first fixing base and the second fixing layer are used for fixing the abrasive grits on the substrate. Moreover, a grinding tool is provided in the present invention.

         7 . The manufacturing method of a grinding tool of  claim 6 , wherein in the step of forming a first fixing base, the first fixing base of a metal layer, a ceramic layer, a composite material layer or a diamond layer is formed on the contact position of the abrasive grit and the substrate by electro-forming, electro-plating, electroless-plating, physical vapor deposition or chemical vapor deposition. 
     
     
         8 . The manufacturing method of a grinding tool of  claim 1 , wherein in the step of forming a second fixing layer, the second fixing layer is formed on the substrate by electro-plating, electroless-plating, physical vapor deposition or chemical vapor deposition so that the second fixing layer covers the first fixing base and the exposed substrate. 
     
     
         9 . The manufacturing method of a grinding tool of  claim 8 , wherein in the step of forming a second fixing layer, the second fixing layer of a metal layer, a ceramic layer, a composite material layer, or a diamond layer is formed on the substrate by electro-plating, electroless-plating, physical vapor deposition or chemical vapor deposition. 
     
     
         10 . A grinding tool, comprising:
 a substrate and a plurality of abrasive grits regularly arranged on the substrate, each of the abrasive grits contacting the substrate on a contact position, a first fixing base disposed on the contact position, a second fixing layer covered the first fixing base and the exposed substrate, wherein the abrasive grits are regularly fixed and arranged on the substrate to form a grinding surface pattern.   
     
     
         11 . The grinding tool of  claim 10 , wherein the substrate is made of metal materials, ceramic materials or high hardness plastics.
