GOOD CUTTING PUNCH AND DIE MAINTENANCEA skilled observer can tell a great deal about both stamping shops and die construction facilities through simple observation. For example, a production shop that routinely shims die details with large stacks of poorly fitting shims probably performs breakdown maintenance in the press. Likewise, die shops that are dirty and poorly organized are not good sources for efficient die maintenance. The term punch and die maintenance often is loosely used to refer to the maintenance of cutting dies. However, pressworking tooling having punches also includes cast iron alloy drawing punches for automotive outer skin panels and form punches for the frame rails used in heavy trucks. Therefore, our discussion is limited to cutting punches and dies. Download the Copyrighted PDF document 153 KB
