Robotic press brakes may offer higher productivity and better profitability--much of which is achieved by running the press brake lights-out at top speed. In some cases, robotic press brakes can reduce per-piece costs by almost half. Still, robotic press brakes aren’t for every application.

Understanding substrates and coatings, and how the coated surface interacts with tube or pipe during the bending process, is necessary to finding a cost-effective, capable combination.

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.
CAM software have made it easier and more affordable for job shops to increase efficiency and productivity without sacrificing quality. Staged bending combined with offline programming offers strategies for reducing downtime, improving part flow, and controlling costs.

Kysor/Warren, Columbus, Ga., cutomizes the refrigerated display cases and refrigeration systems for its customers. Unfortunately, it didn't have a very efficient bending operation to keep up with the production demands related to its diverse product line. To remedy the situation, the company purchased Wila precision ground tooling and installed hydraulic clamping systems on its press brakes.

Within electric brakes, bending force is distributed differently. Also optoelectronic safeguards integrate closely with the control, so much so that a light curtain or similar device has no effect on the bending cycle time. In fact, in the electric press brake arena, safety does not necessarily require a sacrifice in cycle time.

An electric press brake is not typically found in a metal fabricating operation, but that is changing as more companies realize the accuracy, speed, and energy savings that this type of device offers.

Shop rolls beams for a unique place of worship--using an unusual process Abstract: Hardwick Co., a rolling shop in Birmingham, Ala., used its unusual induction beam rolling process to form beams into complex shapes involving multiple radii. Without such capability, the impressive design of the Ave Maria Oratory would not have been possible.

These days, plate rolls are forming plate 6 and 7 inches thick--and even thicker. Vessel designs that would have been forged just a decade ago are now being sent to fabrication houses. The variable-geometry plate roll system, which really operates more like a press brake than a traditional plate roll, is making such extreme rolling possible.

Bending heavy plate and high-strength steel used to require multiple workers, a large amount of bending experience, and lots of time. That's not the case anymore.

Tread plate and perforated sheet present significant bending challenges. To help matters, fabricators may need to look beyond typical air bending with a punch and V die. Though bending alternatives vary, they have one commonality: They clamp down to ensure the workpiece stays where it should.

The increased use of advanced high-strength steels (AHSS) have caused many fabricators to rethink the way they bend metal. AHSS have a relatively high springback associated with it, so much larger overbend angles are generally required. Rotary bending technology is a suitable way to product that overbend angle.

Emerson Network Power's Liebert Precision Cooling facility wanted to implement the idea of one-piece flow on its shop floor in Columbus, Ohio, but the only way that was going to happen effectively was with the introduction of an automated bending cell. The company found its answer with an electric panel bender from Prima Finn-Power.

By regularly checking the four key areas of a press brake—hydraulic circuits, mechanical systems, electrical systems, and tooling—the operator can help to ensure that the brake is always ready to tackle the next bending job.

It's a given that a skilled press brake operator is tough to find. But for entry level workers, what should shop managers be looking for?
