RB Type Profile Bending Machines
Profile bending machines Type RB
Profile bending machines Type RB impress with maximum flexibility and bending performance. The unique machine concept allows the distance between the side roller rolls to be adjusted variably. This enables optimal adaptation of the profile bending machine to the profile being bent. Excessive pressing forces on the profile are avoided. The best possible arc quality with minimal deformation of the profiles is achieved.
The unique machine concept combined with state-of-the-art CNC control technology makes profile bending machines Type RB the first choice when maximum flexibility, performance, precision, and the best bending quality are required.

Good to know:
With all RB type profile bending machines, the bending direction is away from the machine. This ensures increased safety and user-friendliness. A collision of the bent part with the machine or the shaft supports is not possible.
Features:
- Highest versatility and best bending quality due to adjustable center distance
- Highest productivity and bending performance due to high-torque
- Direct drives
- Highest precision through state-of-the-art CNC control technology
Options:
- Fully automatic measurement and correction of the bending radius
- Fourth roll, pull roll or calibration rolls
- Roll bending with mandrel passive or active with boost system
- Helical bending and spiral bending
- 3D bending of profiles with controlled Z-axis
- 3D bending of tubes with controlled rotary axis
- …
Success is controllable
The innovative CNC-S control software for profile bending machines offers unique functions and leaves nothing to be desired, whether for single-part or series production.
