JMT’s new Eco Bend electric press brakes, called ideal for cramped shops where floor space is at a premium, have a compact footprint, run quietly and draw relatively little power while idle. The unique frame design keeps the bend- ing beam precisely parallel to the die.
Models range from 4 to 10 ft. in length, with capacity from 28 to 112 tons. The Eco Bend 10030 is the largest machine in the series, with a 10-ft. maximum bending length and 112 tons of bending force. Energy consumed to manufacture parts reportedly is on the order of less than 40 percent the power consump- tion of a conventional press brake of equal size. Due to the on-demand servo-motor-driven concept, the brakes’ electric motors run only while needed.

This new Goform 40-ton electric press brake from Cincinnati Inc. is touted as perfect for small parts to 0.25-in. thick and weighing less than 50 lb. It provides a 10-in. stroke and 17-in. open height for jobs requiring tall tools and adapters, and boasts a six-axis backgauge to take on complex part shapes. The brake’s heavy-duty stress-relieved frame is designed to handle full-tonnage form- ing with minimal deflection, and its drive system uses satellite roller-screw actuators that minimize heat and wear for a long life of heavy use.
The machine has a small footprint and weighs just over 6000 lb. to allow
it to be easily moved with a forklift or overhead crane, and operates without being anchored to the floor, so it can readily adapt to changing plant layouts and workflows. And, it can be configured to use the three major tooling styles— American, WT/New Standard and European. The Wilson Tool Express Die Holder uses a full-length clamp, rather than multiple setscrews, allowing the use of segmented dies anywhere along
the length of the bed. Programs can be created on the control or offline with Cincinnati’s Bend Simulation Module. Pre-loaded tool files simplify program- ming and improve first-bend accuracy.
