Sick of setup time at the press brake

May 2, 2013 | By Dan Davis

Alto-Shaam, Menomonee Falls, Wis., needed to find a way to reduce setup times for its low-volume, high-mix work associated with fabricating parts for food service equipment. The company found its answer with a panel bender that management had seen in action at a FABTECH tradeshow several years before.

Tooling changeover can be a pressing issue

March 7, 2013 | By Sue Roberts

Press brake manufacturers have responded to industry’s need to produce small batches of parts that require frequent tooling changes by designing options and systems to reduce setup time by managing, storing, and automatically changing upper and lower tools. Operators can spend less time physically involved with setup and more time with the profit-making bending process. Reduced margin for error and less scrap are added benefits. However, there are steps that can be taken to reduce setup time without investing in new press brake equipment.

The basics of applying bend functions

November 9, 2012 | By Steve Benson

Why calculate values such as bend allowance, outside setback, and bend deductions? Because sometimes you will need to work your way around a bend on a print, and you may not have all the information you need to complete a flat pattern.

Bending for the internal customer

October 12, 2012 | By Bill Bossard

Freeing a bending bottleneck can backfire if it simply creates a severe bottleneck downstream. Bending throughput may increase, but overall throughput--the metric that really matters--may not. That’s why the best bending automation considers not only the bending department but also the throughput of the entire plant.

Big bending jobs lead to high-tonnage press brake

May 1, 2012 | By Dan Davis

When a fabricating operation serves customers in the defense, heavy equipment, mining, and power generation industries, you know they are working with really thick and high- strength material. It's a big job and requires big equipment. It's also the main reason that Merrill Fabricators purchased a 2,000-ton, 38-foot press brake.

Bending software streamlines press brake department

February 28, 2012 | By Scott Ottens

Ben endured the same frustrations many press brake department supervisors face. Operators get a print that doesn’t take the proper bend deductions into account. They fudge it, performing test bend after test bend. Productivity suffers, and the bottleneck ensues. At Ben’s shop, this all was about to change.
