A method for producing a rotary dresser.

摘要

A method for producing a rotary dresser includes forming a core piece (10) of an iron-based powder and filling in tungsten or like metal powder (5) between the core piece (10) and an outer mold member (1) containing diamond grit or the like. The construction is then heated to melt and infiltrate a metal alloy infiltrant (6), such that a network structure is formed about the powdered metal particles. In a further embodiment, the core pieces (10) may be arranged concentrically about a metal bushing such that the bushing is included in the final structure.
