for waste, overspray, VOCs, odor or disposal. With its electrostatic atomization venturi system, the lubricant is negatively charged and thus attracted to the neutral, ground- ed workpiece material. This evenly dis- tributes millions of micron-sized particles of either oil-based or solid dry-film lubri- cants across the surface of sheets or coils, producing a uniform lubricated sur- face. This promises to minimize wear and tear on forming equipment and increase tooling life.
A conveyor provides in-out material feed to the edge-rounding line. Aligning rollers position and guide the material, and an edge-rounding unit stabilizes

and rounds the bottom and then top flanges. Says HGG R&D manager Balder de Wolf, “The line can automatically process a radius of 2-3 mm on a beam flange, T-bar and flat bar by rolling the edges. Once the edges are rounded, the beams can easily meet the corrosion-pro- tection requirements.” www.hgg-group.com
Tech Update
Stampers can adjust StaticLube speed from 1 to 1000 ft./min.; use it to lubricate sheet from 0.005 to 0.375 in. thick, and apply coatings of 1 to 1000 mg/sq. ft. Sev- eral standard models accommodate ferrous and nonferrous coil or sheet stock in widths from 1 to 75 in. www.coldwatermachine.com
Edge-Rounding Line Prevents Corrosion While Eliminating Labor-Intensive Grinding
HGG, Charleston, SC, has developed a new edge-rounding line that delivers smooth, rounded surface edges to I- and H-beams, T-bars and flat bars, preventing
