Methods of finishing and microfinishing the edges of a die component are disclosed. Each edge is polished to finish the edge 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 grinding and polishing includes placing a grind fixture adjacent the die component contiguous with the edge to present a grind fixture surface coplanar with the first surface of the edge, then grinding and polishing together the first surface of the edge of the die component and the adjacent grind fixture surface are polished. This is repeated for the second surface of the edge.
A method of micro finishing the edge of a die component comprising, after the die component is machined by known methods, the step of polishing the edge to finish the edge of the die component to a smoother finish than the rest of the die component thereby to reduce the incidence of undesirable streaking defects in the coating, wherein the edge is formed by the intersection of first and second surfaces of the die component, and wherein the polishing step comprises:
A method of finishing a die component having at least one edge defined by first and second intersecting surfaces and comprising the steps of:
