Literature Explains Engineered Clearance for High-Strength Steels

May 1, 2014

A new six-page brochure from Dayton Progress Corp., Dayton, OH, explains how optimizing punch-to-die clearance can significantly affect the quality of the resulting hole characteristics. Also available online, the brochure discusses how the traditional 5-percent-per-side clearance proves insufficient for stamping many state-of-the-art high-strength steels. It walks readers through proper clearance specification based on material type and tensile strength, workpiece thickness and application requirements.

In addition to a smaller burr, cleaner burnish and break patterns on the perforation, matching the clearance to the material also can extend the service life of the punch. This literature is ideal for those involved with all types of punching or perforating including high-speed, high-volume punching.
