Maximum Bending Speed

Small CNC models reach bending speeds up to 200 degrees per second, with servo feedback supporting repeatable output.

Bending System

Freedom Design

The EB-RH bending head drive system combines 360-degree rotation with vertical and horizontal axis movement for complex CNC bending, fast positioning, and easier automation integration.

The EB-RH bending head drive system provides complete freedom of movement. Its 360-degree rotation works together with vertical and horizontal axes for quick positioning during complex bending work, while the rotation solution remains compact and maintenance-free.

The 360-degree rotation system and the vertical and horizontal movements expand the bending head travel range. When needed, the head can be deflected so the positioning carriage advances beyond normal limits, making integration with automatic loading and unloading systems easier.

The bending head structure is robust, lightweight, and low in inertia. This supports high bending speeds, rapid tool selection adjustments, and shorter cycle times for complex CNC tube bending workpieces.
