Optimizing the punch-to-die clearance, which cansignificantly affect the quality of the resulting hole characteristics,is detailed in a new 6-page, full-color brochure available from DaytonProgress Corporation. Engineered Clearance discusses how the 5% per sideclearance is insufficient for today's high-strength steels, and walksreaders 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. This literature is ideal for those involved with all types of punching or perforating including high-speed, high-volume punching.
