Fully Electric CNC Steel Tube Bender With Rotative Head - EB-RH Series

KRRASS Advanced CNC Steel Tube Bender
KRRASS’s fully electric EB-RH series steel tube benders, with rotating heads, contain the most advanced Electric Motion technology on the market with 11 fully electric drive shafts. This range of machines can bend pipes and profiles from 6 to 53 mm with even radii up to 1D with minimal marking when equipped with the booster system. The bending head moves 360º on a radial axis and horizontal and vertical axes. This system offers complete freedom of movement and allows the production of very complex parts in an automatic bending cycle.


100% electric drive of all 11 axles.

Bending head with 360 ° radial axis and horizontal and vertical linear axis.

Bending of multiple fixed and variable radii in the same cycle.
Main Features EB-RH Series
The cycle speed and low energy consumption make these steel tube benders ideal for high-volume and consistent production. Because the level of automation is so advanced, they are easy to integrate into automatic production lines or combine with automatic loading and unloading elements. Thanks to advanced 3D software, the steel tube bender has become an Industry 4.0 machine.

Freedom Of Movement...
The EB-RH series bending head drive system provides complete freedom of movement. The 360° rotation, combined with the vertical and horizontal axes, allows a quick positioning for the production of very complex bending work. The solution chosen by KRRASS for the rotation is extremely compact and maintenance-free.
It is structurally robust yet lightweight and with a low inertia, allowing for high bending speeds and rapid tool selection adjustments. This unique design dramatically reduces the cycle time of complex bending workpieces.


Easy Integration
The 360º rotation system, together with the vertical and horizontal movements, contributes to the wide range of movement of the bending head and, if necessary, deflecting the head so that the positioning carriage advances beyond its normal limits.
This feature is particularly important to facilitate integration with automatic loading and unloading systems.
