ABSTRACT:
A method of producing a rotary dresser include forming a core piece of an iron-base powder and filling in tungsten or like metal powder between the core and an outer mold member containing diamond grit or the like. The construction is then heated to melt and infiltrate a metal alloy, such that a network structure is formed about the powdered metal particles. In a further embodiment, the metal materials may be arranged in concentric form about a metal bushing such that the bushing is included in the final structure.
