4-Roll Bending Machine
Whether for series production or complex bending tasks – our four-roll bending machines offer the highest precision and efficiency. The RBB impresses with its easy operation and repeatable material guiding – ideal for consistent bending processes with minimal waste. The RBA, on the other hand, enables maximum flexibility through its NC or CNC control and is perfect for different sheet thicknesses and demanding bending shapes. Find the right solution for your production!
Overview of our machines
Four-Roll Bending Machine RBB
The RBB is the ideal entry-level model for precise bending of pipes and shapes. Thanks to the four-roll technology and an SPS control, the machine allows controlled pre-bending and after-bending, resulting in accurate sheet metal pipes that can then be easily processed on longitudinal seam welding machines using laser or TIG welding methods.
Performance Features
- Precise feed & exact bending angle through infinitely adjustable motors
- Automatic sheet thickness adjustment using pneumatic cylinders
- Fixed rear stop for repeatable pre-bending
- Intuitive control via SPS with touchscreen control panel
- Durable bending rolls made of high-strength material, hardened or ground upon request
All advantages at a glance!
- Perfect for series production & repeatability
- Ensures precise and even bending through optimal material guidance
- Minimizes material waste thanks to precise four-roll technology
- Facilitates operation through intuitive control and ease of handling
- Enables high repeatability in series production
- Reduces setup times for efficient production
Four-Roll Bending Machine RBA
The RBA bending automation is the high-end solution for the precise and efficient rounding of sheet metal parts and shapes. It combines the highest accuracy with maximum speed and is thus ideal for modern sheet metal processing companies. Whether manual loading and unloading or fully automatic integration into a pipe production line – the RBA offers maximum flexibility for a wide range of production requirements.
