As reported by The Fabricator in their article, “Servo Press Puts Reverse Tonnage in Reverse,” Clips & Clamps faced a unique challenge when forming stainless steel parts on a 300-ton mechanical press. The process pushed the press to its maximum capacity, encountering extreme reverse tonnage that strained the press, tooling, and the entire system.
The material in question was a 1/8-inch-thick, 78 Rockwell stainless steel, described by company President Jeff Aznavorian as “wicked.” The part’s structural integrity demanded this robust material, which was purchased mill-direct due to its specific requirements. To meet production needs, the die design required blanking the entire profile in a single stroke, pushing forward tonnage close to the 300-ton limit and generating reverse tonnage exceeding 100 tons—a significant concern given that reverse tonnage should typically remain below 10% of the press’s capacity.
The company couldn’t reduce the press speed below 45 strokes per minute due to material breakthrough risks. This led to loud operation conditions and vibrations strong enough to ripple water in a glass three football fields away from the press.
Servo presses offer a solution to these challenges by handling high reverse tonnage and demanding materials with greater efficiency and control. Their expertise in servo press technology ensures manufacturers like Clips & Clamps achieve the precision and durability required for high-stress applications.
