The lightweight tool requires no electricity and provides a controlled, powerful hold on range of steels—flat or curved.
The progressive actuation of the magnetic force provides precise positioning before applying the full-magnet hold. Importantly, according to company officials, the magnet turns completely off and does not accumulate magnetic material from the drill site. For increased safety, the locking feature of the base prevents magnet arrays from deactivating during use, thus ensuring safer tool operation.
Breakthrough Capacitor-Discharge Resistance-Welding TechnologyDengensha America demonstrated its new Flexwave resistance-weld machine, with flexible waveform technology, at FABTECH. The machine combines the capabilities of a capacitive-discharge welder (CDW) and a 15,000-Hz bipolar medium-frequency converter (MFC) to offer enhanced control of energy release. We saw firsthand how the technology controls heat input and optimizes weld-nugget quality on steel and aluminum, as well as dissimilar materials, with weld parameters that are simple to set. And, the technology maximizes waveform flexibility, allowing fine-tuning of tempering, demagnetization, upslope, etc.
The new Flexwave Welder Series includes the NICP-050, NICP-100, and NICP-150 models, with maximum weld currents of 50,000, 100,000 and 150,000 A respectively.
Automated Bending Cell

Recommended for high-speed forming of small, complex parts, Amada showed off cell features such as automatic angle measuring, offline programming, multiple part-load/unload stations and an automatic tool changer. Its six-axis robot travels along the ground in front of the press brake.
In addition to loading blanks into the brake and handling the workpiece throughout the bending process, the robot can stack completed parts, or place them in boxes or on a synchronized conveyor belt. The robot also can change bending tools and grippers, and can carry out process steps that cannot be achieved if the press brake is operated manually. For example, the mechanical grippers can be guided around the tools in the press brake’s working area in order to ensure optimum assistance during operation tracking.
Multiprocess Power Source Maximizes Welding Flexibility
The Lincoln Electric Co. Cleveland, OH, had a major presence at FABTECH, with multiple booths and a variety of fabricating technology in use and on display.

Fully protected components and its light weight make it ideal for outdoor use and harsh environments, and the IP23-rated welder reportedly runs cool even in high-temperature settings.
With a streamlined operator panel designed to minimize setup time and simplify process selection, the Flextec 350X is compatible with multiple wire-feeder types, including across-the-arc, analog, digital or Lincoln Electric’s CrossLinc wire feeders. CrossLinc technology uses a proprietary communication protocol to maintain voltage control at the feeder, while eliminating an extra cable. The result is greater safety, quality and productivity, according to company officials.
Newly Designed Sheetmetal Lifting Equipment and Suction Cups
Fipa Inc., Cary, NC, exhibited and demonstrated its lifting technology, including FipaLift tube lifters as well as oval suction cups for sheetmetal-handling applications. The manually guided FipaLift tube lifters allow a single person to safely lift, transport and precisely position as much as 640 lb. of sheetmetal in a short cycle time and with minimal physical exertion. The lifters can handle structured, smooth, oily, dry, nonmagnetic and hot metal sheets without the risk of dents, scratches or exposure to paint-impairing substances, according to company officials. These lifters eliminate laborious, accident-prone and economically inefficient manual-handling processes in harsh production environments—even for heavy or awkwardly shaped sheets that otherwise would require the combined efforts of two or more people or robotic lifting equipment.
Panel Bending Redefined
Trumpf’s new TruBend Center 5030 panel-bending machine, presented as the perfect complement to its TruBend press-brake product line, displayed its ability to produce positive and negative bends, folds and circular bends with a variety of radii, all while minimizing setup times and tooling costs. With a bending length of 10 ft., the TruBend Center 5030 is a thin-sheet processing specialist. Operators insert the workpiece material against the backgauge and the two-axis part manipulator performs all additional material handling required for bending steps along that edge; the bending tool moves to form each bend. The machine operator then turns the sheet and the process begins again.
A unique design feature is the machine’s additional vertical axis for the part manipulator. Since the part manipulator can fix parts at a range of positions, this axis optimizes flexibility and provides for easy removal of parts with downward edges.
With standard tools, the TruBend Center allows can form aluminum and mild-steel sheets to 0.120 in. thick and stainless-steel sheets to 0.090 in. Possibilities include short side lengths, deep boxes and small profiles, as well as parts with formed sections, recesses and diverse radii. The machine can also productively process galvanized and painted sheetmetal. To form parts with challenging geometries, such as very small profiles, formed sections near the bending line, flanges or staggered bends, additional blankholders and bending tools are available. The machine’s optical angle assistant ensures accuracy and proves particularly helpful when setting up new parts.
40-Ton Electric Press Brake Ideal for Small Parts, Tall Tools
Cincinnati Inc. introduced its all-electric GoForm 40-ton press brake, ideal for small parts to 0.25 in. thick and weighing less than 50 lb. The brake features a 10-in. stroke, and with its 17-in. open height, can handle tall tools and adapters. A heavy-duty stress-relieved frame makes the machine ready for multi-shift operation, according to company officials, and is designed for full tonnage with minimal deflection. The drive system uses satellite roller-screw actuators that reduce heat and wear for heavy use and long life. A six-axis backgauge handles basic and complex part shapes.
“The machine has a small footprint, can be easily moved with a forklift or overhead crane, and operates without being anchored to the floor,” says product manager Todd Kirchoff, “so it can adapt to changing plant layouts and workflows.”
Nidec Minster Showcases Robot-Tended Servo Press
