How to Reduce Tonnage?
There are a variety of ways to reduce the required press tonnage.
• Use Tonnage Compensator Caps – Stagger the punch length so that the punches pierce the material at different intervals
• Add Punch Shear – A shear angle ground onto the punch tip reduces the load or tonnage unlike flat faced punches
• Use correct die clearance – This results in a balance of punching force, good hole quality and increased tool life
• Sharpen punches & dies often
Are your punching capabilities limited by the tonnage of your press or press brake? UniPunch has a solution. Compensator caps stagger the punch length so that the punches pierce the material at different intervals, reducing the required punching tonnage. They are fastened to the punch heads of “A” and “AJ” series units to reduce the total punching load required for multiple holes.
