AMADA bending solutions at FABTECH emphasize the “e”
In a major technology move, AMADA America launches important new additions to its bending solutions. As will be shown at FABTECH 2023, all press brake models up to and including 1303 models (130 ton/3-meter bed) will be driven by electric servo motors only. Hydraulics will be used only in larger press brakes.
Also new to the electric strategy is using a single motor for each ram. Rather than a motor for approach and a separate motor for bending on each ram, a transmission specifically designed for press brake work is employed. It is a more efficient and more reliable design.
This is an entirely new, high-speed torque system for AMADA America. Two speeds are inherent in this new system:
- Approach speed: this is the speed used to move the punches down toward the dies before engaging in bending. The approach speed is 250mm/sec.
- Bend speed: Once the punch reaches the bend area, the transmission slows it down to 25mm/sec.
Electric crowning is another innovation in the EGB series (see Figure 1). The new system enables different crowning outputs on the left and right sides. The amount of crowning force on each side is controlled by an independent cam. With a variety of table shapes, it is now possible to correct workpieces that were previously difficult to process.
New control
The new EGB Series press brakes comes standard with the AMNC 4ie control (see Figure 2), an upgrade from the AMNC 3i. Several new capabilities come with the AMNC 4ie:
- Facial recognition is a part of the system—an operator is recognized and the system grants operator rights based on who is using the system (for example, based on experience level);
- You can preset an idle stop, for example if the operator walks away and stays away for a preset amount of time;
- The size of the control screen has increased, from 18.5” to 21.5”;
- The control has a reduced number of hand switches—most of the operation occurs on the touch screen; and
- The new system can scan and recognize QR codes for data input.
Putting another meaning to the “e,” and to further deliver on its eco-aware strategy, the AMNC 4ie’s idle stop function puts power-consuming system components into a sleep mode. The servo motor, heat exchanger, display, and working light are shut down during this time, and the system can be restarted manually or automatically, specific to each customer’s work environment.
Varied capacities for varied environments
Five EGB Series press brakes are all-electric, and come in a variety of capacities:
- The EGB 4010 e is a 40-ton, 1-meter press brake;
- The EGB 6013 e is a 60-ton, 1.3-meter press brake;
- The EGB 6020 e is a 60-ton, 2-meter press brake and it replaces the HG 5020 press brake;
- The EGB 8025 e is an 80-ton, 2.5-meter press brake; and
- The EGB 1303 e is a 130-ton, 3-meter press brake.
The EGB 1303 e and the EGB 6013 e will be shown at FABTECH 2023 in their robotic formats, the EGB 1303 ARse and the EGB 6013 ARce, respectively. Each model features a robot in front of the press brake that handles bending duties. On the smaller EGB 6013 ARce, it also does punch and die placement. The larger EGB 1303 ARse uses the time-tested AMADA ATC for automated punch and die placement, leaving the front-side robot to accomplish only the bending tasks.
More information about the EGB 1303 ARse, the EGB 6013 ARce, and the EGB 6020 ATCe is available in this issue of AMADA InTech.
