Internal structure of the electric mini press brake

High Rigidity Frame

The machine bed and key components, including the moving tool holder, use welded steel plate structures for strength and stability
The design features symmetrical weight distribution and reinforced ribs in the spindle box for support. Finite element analysis ensures optimal rigidity and stability
To prevent deformation, the bed undergoes annealing to eliminate internal stress. Machining is done on a five-sided CNC center in one clamping, ensuring high accuracy and long-term precision

Controller

ECO-10ES CNC system uses advanced bending algorithms and industrial-grade chips, with EMC and temperature adaptability certifications
The direct programming function simplifies operations by allowing easy input of bending parameters for efficient processing

Synchronous Control Device

The spindle power box uses heavy-duty ball screws and bearings for durability, with sealed protection to prevent dust damage

Backgauge

The rear material stop features 2-4 axis design, driven by AC servo motors paired with high-precision reducers. Controlled by the system, it moves quickly and accurately to the required position
During bending, the rear stop automatically avoids collisions with the workpiece

Fast Clamp

The upper die features a precision quick clamping function for easy die changing, increasing production efficiency
2 V-dies have a simple design for easy mold changes, offering high hardness, toughness, and wear resistance
Bending tool undergoes uniform heat treatment for long life and high precision, reducing correction steps and processing costs. Heat-treated dies provide greater durability than standard molds

Frequently Asked Questions

Why is it better to choose dual motors for the main motor?

Most machines on the market use a single-drive/mainframe configuration. Such single-drive designs are prone to torsional deflection and can cause premature ball-screw failure. Unless the machine is used only for small parts or for center-line bending, performing side/edge bends on thick plates will typically produce the problems described above.

Can ERSM's small press brake be equipped with a robot?

The press brake can be optionally fitted with a robotic loading/unloading unit to create a fully automated bending cell. The robot performs loading, unloading, part flipping, and precise positioning, while the press brake handles the forming operation. The integrated line runs stably with controlled cycle times. This configuration is suitable for thin-material, multi-variant bending tasks and can raise both throughput and part quality within a limited shop floor footprint.

Can this mini press brake handle bending acute angles/obtuse angles/arcs for my workpieces? Do I need to replace the dies additionally?

Generally, our mini press brake can bend acute angles, obtuse angles, arcs, and even process complex small workpieces by simply replacing the corresponding dies. Below are examples of workpieces bent with this machine (e.g., small chassis, hardware parts, etc.).
