ABSTRACT:
A multilayer abrading tool is produced by first providing a tool substrate with an irregular abrading surface. The irregular surface is covered with metal balls which are brazed thereto to form a structured surface. An abrasive grit coating is provided by mixing a temporary binder, an abrasive grit material and an infiltrant powder material. This coating is then applied to the structured surface. The tool is then heated to drive off the binder and to cause infiltration of the infiltrant in the abrasive grit to form a multilayer of diamond grit suspended to a braze matrix which is attached to the structured surface of the tool substrate.
