RB60

The precise 3-roll bending machine

When developing the compact and mobile horizontal bending machine the focus was clearly on the production of true-to-size helices, like, for example, handrails for spiral staircases. This is the supreme discipline since two parameters influencing each other (radius and inclination) have to be united to a trueto- size geometry in a bend. The interplay between tube calculation on the PC, implementation on the bending machine and the control via measuring devices with final correction of the bending values ensure accurately fitting bending. By only few and simple input in the PC tube calculation program, the local printer provides a print-out and supports the calculation of all necessary bending and correction data for working on the machine. A new powerful drive concept enables continuously variable setting of the bending speed and only requires a 230 V AC power connection. Hardened steel tools as well as surface-protecting hard plastic tools are available. In order to ensure optimum feed also with narrow bending radii, all three bending shafts are driven. Also at daily hard work in the plane when bending tubes and profiles, this drive system has proven its worth. Customers using the bending systems 4800, 5000 and 6000 have the possibility to purchase the roll bending unit without a drive. The roll bending unit with the designation RB43 can be adapted via the flexible shaft on the bending systems 4800, 5000 and 6000. The machines act as a drive unit here.
