Hello All,
If I am wanting to hold a die punch clearance of 0.0002" per side on a die cutting tool what types of materials would you consider using and at what Rc hardness's would you consider for the upper punch and lower die shoe. This is a four posted die tool by the way using precision ball cages, posts and bushings. Just wanting to see what others do (processes, materials, hardness, matching, etc.) when having to hold ultra tight tolerances on fine blanking die punches. Don't consider the thickness of the material for this post.
