ABSTRACT:
A method of microfinishing the edge of a die component includes polishing the edges after the die component is machined by known methods to finish the edges of the die component to a smoother finish than the rest of the die component. This eliminates the incidence of undesirable streaking defects in the coating. The polishing step can be lapping, vapor honing, or grit blasting. The edges are polished to a finish of less than 8 microinches.
