With the R3a, AMB picot opens the door to sheet metal rolling.

3 rolls
1 to 5 mm capacities (S235 steel )
Useful length: 1-2 m

Electromechanical asymmetrical 3-rollers are an excellent entry point into the world of sheet metal rolling. Designed to offer a good compromise between performance, ease of use and moderate cost, they are an ideal first investment for workshops wishing to familiarize themselves with this essential sheet metalworking process.

Thanks to their asymmetrical design, these machines enable easier sheet positioning and efficient pre-bending, while remaining simple to set up and maintain. The electromechanical drive ensures enhanced reliability, low energy consumption and silent operation, suitable for a wide range of production environments.

Perfect for small production runs, prototypes or single parts, they are particularly well suited to craftsmen, SMEs or training centers wishing to develop their know-how without mobilizing a large budget. They are both educational and professional equipment, enabling you to learn the basics of rolling while producing precise, high-quality parts.

By investing in an electromechanical asymmetrical 3-roller caster, you’re opting for versatility, simplicity and efficiency, while retaining the possibility of upgrading to more complex equipment as your needs grow.

R3a What are the advantages of SHEET BENDING MACHINE

with three asymmetrical roller technology

2 powered rollers

One motor (gearmotor) per roller as standard. Our machines have been equipped with Danfoss motors for over 35 years. The rotation of the rollers is factory-synchronised by a hydraulic system that prevents any variation over time.

Benefits: maximum torque, optimised efficiency, synchronised speed, reliability.

Note: Our competitors only have one or two powered rollers as standard.

Special architecture: design for identical roller diameters

To guarantee the best performance in terms of bending and deformation of the part, we have three rollers of identical diameter.

The benefits: perfect geometry in the bending profile and better machine capacity.

Note: Our competitors’ lateral rollers have much smaller diameters -> reduced capacity

-> up to 30% additional bending.

Linear guide system

An incredibly useful technology, with no friction and excellent performance in all operating modes: cylindrical and conical rolling. It’s also a strategic choice for optimised prebending (on three- and four-roller machines)

Benefits: maximum efficiency of the hydraulic power, no wear.

Note: The planetary guide system used by our competitors is a low-cost solution

-> up to 30% loss of power and additional wear.

Bronze Bearing Technology

All of our machines are equipped with bronze bearings that accept high loads during rolling operations.

This technology is unrivalled in terms of both its capabilities and its longevity! Greasing is centralised and requires no maintenance.

Note: Our competitors use roller bearings (more economical, but unable to withstand heavy loading).

CONTROL

The standard version of the R3a includes a bidirectional foot pedal.

An optional control panel with a touchscreen and a joystick for plate rotation control is available, providing real-time position display of the bending roll..

SOFTWARE

As option: discover quickroll, the roll-bending assistance software, providing you with successive positions of the bending roll, adjusted based on your material.

This software is also available on PC tablets..

CONTROL EQUIPEMENT

Available options

Adjustable stopper to assist with cone rolling.

Inner and outer diameter measuring system – 2 types of supports for large or small diameters.

*Machines capacity are provided for information only, based on S235 steel type of material (Yield strength = 240 N/mm² = 34,800 Psi).
