Metal fabricators are familiar with forming shapes such as louvers on a punching machine, but that's just the tip of the iceberg. Punching tools today can produce forms, such as hinges, which could be used to streamline production on the shop floor. Fabricators just need to open their eyes and take in the possibilities.

One of the most mature technologies in metal fabrication, punching is also one of the most misunderstood, perhaps because the process can ccomplish so much—punch myriad shapes, form, even bend flanges. Regardless, if a shop follows some basic strategies, it will be well on its way to better parts and greater throughput.

Removing the skeleton from a machine tool is a time-consuming and potentially dangerous task. Machine tool builders recognize this and are taking steps to eliminate that manual effort.
Ten years ago The FABRICATOR ran an article titled "Punch it, laser-cut it, or something else?" which looked at the different machines available to perform basic fabrication operations. New technology has changed the thinking a bit when it comes to the discussion of what can be accomplished with laser cutting and punching machines. This article sequel tackles those points.

Carter Day International punches thousands of holes to make specialized screens. One screen can take several hours to punch. Problem is, the company doesn’t have enough volume to warrant using a specialized perforation press. So it uses a traditional turret punch press, but with highly durable tooling.

Several factors come into play when trying to determine the appropriate lifespan of a punch before major maintenance or replacement is required. If a fabricating operation is knowledgeable about punching activities and vigilant about organization and maintenance, it can expect to get the most out of its tooling.
