The evolution of precision bending

June 17, 2008

By:

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.

Specials simplify the complex, speed productivity

February 12, 2008

By:

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:

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.

Automatic or manual?

October 9, 2007

By:

While automation can increase throughput and reduce labor, it doesn't solve manufacturing problems. A manual process that produces poor-quality or inconsistent parts will simply do so at a faster rate if automated. Understanding the process and process variables is the key to troubleshooting problems and resolving them to get the maximum gain from automation.
