Diemakers have several options for slug-pulling problems, such as knockout pins, vacuums, punch or die dulling, oil viscosity, wire EDM hole slots, punch/die clearance changes, edge shearing, mechanical grippers, air jets, and cuped-shaped punches. Another method to help stop slug pulling is bell- mouthing the die, which essentially involves cutting a funnel shape around the hole.
The PIPE-MAX is a combination grinder and pipe belt sander. The front hard rubber contact roller drives the abrasive belt to grind flat surfaces. It removes weld seams in a straight line, without leaving edges or a wavy finish. For sanding pipes or handrails, the sanding belt follows every contour to grind and polish up to a high-gloss finish. Ideal for stainless steel, aluminum and high-quality metals.
