Die Science: Solving punch breakage problems - Part II

January 9, 2007

By:

Cutting shear, or the angle ground into the end of a punch, has a big effect on punch deflection and breakage, as well as press tonnage required. Retainers, which hold the punch to the die shoe, also are important. The backing plates, ball lock punch retainers, and headed styles of punches and retainers all require careful consideration.
