Optimizing Punch-To-Die Clearance

Optimizing the punch-to-die clearance, which can significantly affect the quality of the resulting hole characteristics, is detailed in a new 6-page, full-color brochure available from Dayton Progress Corporation (Dayton, OH).

Available in print or online here, Engineered Clearance discusses how the 5 percent per side clearance is insufficient for today’s high-strength steels, and walks readers through how to select the proper clearance based on material, thickness, tensile strength, and the requirements of the specific job. In addition to smaller burr, clean burnish and break patterns on the perforation, matching the clearance to the material can also extend the service life of the punch.
