The bending technology area includes all manner of machines and processes for bending sheet metal, including press brakes, folders, panel benders, corner formers, ironworkers, notchers, orbital formers, and roll benders. It also has information on accessories such as gauging and backgauging systems.

Expensive options on a press brake won't guarantee knowledge transfer from a veteran press brake operator to a shop floor rookie. For knowledge transfer to occur, a shop needs experienced workers that can communicate and a younger work force eager to learn because they see a future in metal fabricating.

Greiner specializes in structural steel and heavy plate fabrication. It does work for power plants and the mining industry. In the 33 years the company has been in business, it has done structural steel jobs in an industry where the work always seems to be getting larger and heavier. It recently installed a 40-ft.-long press brake that weighs more than 800,000 lbs.

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.
Tooling manufacturers have introduced tooling designed to overcome the longstanding problems associated with staged bending.
