The entire series of Stierli radial bending machines features the same general design: material is bent around a bending pin by a rotating drive. Stierli radial benders are characterized by their ease of operation, low tooling costs and high repeat accuracy.
Stierli radial benders offer an excellent solution for bending medium-sized radii with angles between 0- and ~270-degrees. Radial bending allows for a larger range of bending angles than a traditional horizontal bending machine. Radial bending provides outstanding results in applications involving repeated radii, arch segments, bends over 90°, spirals, enclosed shapes and many other applications. They are ideal for bracketing, decorative designs, and ornamental hardware in steel, copper, aluminum and other materials.
The working torque of the series ranges from 1850 pounds/foot (2500 Nm) to 9600 pounds/foot (13,000 Nm). Each machine comes standard with a 15-inch or optional 23-inch diameter rotating bending plate. These plates as well as the machine table have many points to mount different tooling and part support pieces to the machine. The radial series comes with Stierli’s simple CNC control with modern touchscreen display and 2-axis control, which offers the ability to program the angle of any bend and gives full control of the optional 1-, 2- or 3-meter back gauge for fast, accurate positioning of the part. The control can hold up to 200 programs with 15 steps each.
