Thinking outside the press brake

October 5, 2009 | By Tim Heston

Automating bending with a press brake tied to a robot isn't the only option. Panel benders and folding technologies have evolved to handle more parts and various lot sizes.

The evolution of precision bending

June 17, 2008 | By Joseph Altieri

Three decades ago bottoming with penetration, or coining, was the only way to achieve high accuracies on press brakes, and this meant fabricators endured high tooling costs. Over the years precision air bending with CNC hydraulic press brakes using precision-ground tooling evolved to become the dominant forming method in the precision market. However, it took some significant machinery advances to get there.

Special press brake tools

Specials simplify the complex, speed productivity

February 12, 2008 | By Tim Heston

Standardized press brake tooling, absolutely necessary for a lean organization, keeps a shop flexible, but at the same time, ignoring specials would be a big mistake. If their slightly longer setup times also lead to a drastic increase in throughput, special tools make good business sense.

2 strategies for optimizing bending operations

January 15, 2008 | By Michael Bishop

Fabricators typically encounter bottlenecks during setup and production in their press brake bending operations—obstacles that lead to downtime and fewer operators actually processing material. Representatives from Amada, LVD Strippit, Bystronic Inc. addressed these issues in a recent presentation. The two largest problems? Performing non-value-added steps and having to compensate for material variations. Fortunately, some new technologies and two key strategies can help fabricators optimize their press brake operations in these areas.

Dealing with Mother Nature's wrath

October 9, 2007

Protecting a two-mile-long, 10-lane bridge from earthquake damage is not an easy task. Replacing the eastern span of the San Francisco-Oakland Bay Bridge requires the talent and time of numerous design firms and fabricators and tens of thousands of workers. One of the more interesting fabrication...
