Overview of Our Machines
Four-Roller Round Bending Machine RBB
The RBB is the ideal entry-level model for precise bending of round pipes and other shapes. Thanks to the four-roll technology and a PLC control, the machine enables controlled pre-bending and post-bending, producing precise sheet metal tubes. These can then be easily further processed on longitudinal seam welding machines using laser or TIG welding methods.
Performance Features
- Precise feed & exact bending angle through infinitely adjustable motors
- Semi-automatic sheet thickness setting via pneumatic cylinder
- Fixed rear stop for precise repeatable insertion
- Intuitive control via PLC with touchscreen control panel
- Durable bending rolls made of high-strength material, optionally hardened or ground
All Advantages at a Glance!
- Perfectly suited for series production
- Ensures precise and consistent bending through optimal material guidance
- Facilitates operation through intuitive control and easy handling
- Allows for high repeatability in series production
- Reduces setup times for efficient production
