Manually Controlled Machines

The manual control is the simplest available on Stierli-Bieger bending/straightening machines and is the basic control for all machine sizes. The simple easy-to-understand design has proven reliable for decades. The ability to adjust and lock the ram stroke depth under pressure allows for easy and repeatable bending operations. Stierli bending and straightening machines range in working power from 9- to 660-tons.

Simple CNC Machines

Stierli’s simple CNC controls offer the ability to program the stroke length into the machine, either by “teaching in” the position of the punch, directly entering a value, or optionally to program the angle of the bend. It gives full control of the optional 1-, 2- or 3-meter back gauge for fast, accurate positioning of the workpiece. The control can hold up to 200 programs with 15 steps each. Stierli bending and straightening machines range in working power from 13- to 660-tons.

Graphical CNC Machines

Stierli’s Graphical CNC Machines deliver outstanding results for both bending and straightening. Its CNC control enables programming for stroke length by entering either the angle, stroke or specifying the stroke depth. Controls can be programmed through the network or through a CAD CAM connection. The control can hold up to 100,000 programs with 15 steps each. The working power of these machines range from 24- to 90 tons.

Radial Bending

Radial bending works by bending material around a bending pin via rotating drive. The bending pin diameter determines the bend radius, and the rotation of the drive determines the bend angle. Radial bending machines are ideal for a variety of applications and industries, including decorative and ornamental hardware. Machines come with simple CNC controls allow programming for the angle of the 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.

Benders for Railroads

Stierli-Bieger has developed a series of benders specifically for the rail industry. Benders are available in 200-, 300- and 400-ton versions. Stierli’s unique horizontal design allows even the largest rail profiles to be handled with ease. Each machine features simple manual control systems and ultra-modern CNC tools with laser guidance systems and a high degree of process reliability and automation.

Benders for Ship Building

Stierli-Bieger designs bending machines specifically to meet the needs of the shipbuilding industry. Along with the typical HP ship’s frame (also known as a Holland profile, HP frame or bulb flat), Stierli benders will also accommodate L profiles and T profiles. With a central clamp system to hold the material on in tooling, during the bending operation, our benders are highly productive and compact. Each machine features simple manual control systems and innovative CNC tools with laser systems and a high degree of process reliability and automation.
