adds a fifth roll at the bottom of the tube, allowing smaller diameter side rolls to be used. Many smaller mills use three rolls mounted 120 degrees apart. Some are orientated with a grooved roll at the top of the tube (D), others with a roll directly below the tube. D eliminates edge misalignment and is especially suited to D/T ratios above 10:1.

Aug 08, 2006· While the first step in successful punching is to pay close attention to the quality and features of punching tooling, other factors come into play. Punched slugs are clues, and examining them can reveal whether the punch and die clearance is too loose or too tight and whether the machine is properly aligned.
