HZ Series Overview

Horizontal Punching Units

“HZ” series punching units are designed for horizontal punching of holes in the vertical sides of flanges, rims and formed parts. In operation, the press ram depresses the vertical plunger forcing the punch horizontally through the material. On the up stroke of the ram, the stripping spring removes the punch from the work piece. Available “HZ” series holder widths are: 3/4”, 1 1/4”, 1 1/2” and 2”. Holder width is important because it defines the minimum hole to hole distance. The “HZ” series is widely used in industry to punch mild steel from 3/32” to 1/4″ thickness. Depending on your material thickness, punch diameters are available from .0937” (2.38mm) to .875” (22.22mm). (For other formed part punching applications, see the “AJ” series.)

In addition to a wide range of standard round and shaped punches and dies, UniPunch provides punch and die pairs in shapes custom made to your specifications. UniPunch units are rugged holders that allow you to punch burr-free holes with minimal maintenance. Various mounting methods are available including dedicated templates for fast changeover at the press.
