Powerful bending and straightening solutions that will impress you
With its various tool solutions, the Stierli bending machine is very versatile. Its open design provides plenty of advantages for manufacturing bent parts, metalworking and straightening work. As a universal bending machine and straightening machine, the Stierli metal benders are used in numerous industries and for both single part/small series production and series manufacturing. Various 1- or 2 axis control concepts, including manual bending machines and powerful CNC bending machines, provide the operator with optimal support in the production process.
Models of horizontal metal bending machines
|Horizontal bending machines with manual control system
|The bending programm will be created by the operator. Corrections of angles and back gauge (length stop) during the bending process are possible.
|The bending programm will be created fully automatically by entering the angle and the leg length. Incl. material and tooling library (as with a modern vertical press brake)
|Same as CNC-W, but with additional active angle measuring during the bending process, incl. automatic correction (autom. rebending)

Our bending centre is now also available with an automatic bending robot.
At a glance: characteristics of our horizontal folding machines
The Stierli benders impresses with its countless advantages:
- Larger and wider working table
The working area has generous dimensions, which means that larger bending parts can be positioned securely.
- Long cylinder stroke with large insertion width
When it comes to aligning welded structures or using special tools, having sufficiently large stroke and insertion width is a big advantage.
- Robust machine design
The rigid, robust design of the machine guarantees precise working with excellent long-term accuracy.
- High repeat accuracy
The combination of a very rigid machine design, precise hydraulics and the use of high-quality control components results in high repeat accuracy.
- Very strong cylinder guiding system
The very strong cylinder design means that open guides are not required. The entirely enclosed guide system offers many advantages that help to maintain a long service life and long-term accuracy:
- The guide system is protected against wear
(in contrast to open guides)
- No additional lubrication required, no need for servicing.
- Our guide concept allows the working table to be completely enclosed
(see next point)
- Precise, enclosed working table
The mechanically finished machine table provides a flat, clean surface. It is completely enclosed and does not require any openings for additional guides. As a result, small bending parts do not become jammed and scale cannot enter the guide system.
- Movable with pallet lift truck or crane
If necessary, the Stierli metal bending machine can be moved easily to wherever it is required.
- Little space required
The compact design means that the Stierli bending machine can be used anywhere in the workshop.
- Compact, flexible and robust quality tools
Stierli-Bieger offers tools which, on the one hand, allow fine machining with small leg lengths, small U, L or Z bending dimensions. On the other hand, heavy-duty, strong bending tools are available for heavy bending machining.
- Quick-change tool system
Changing tools takes a matter of seconds.
- Universal application
Numerous tools and accessories are available, offering an enormous production potential for a large fabrication range.
Profile, tubes, metal strips, sheet metal, bars, different steel types and steel grade, mild steel, stainless steel inox, hardox etc... Standard tools are available and special tools with e.q clamping systems for special sections.
Tools with automatic angle correction head for high precision are also available for flat bar, profile and round bar.
- High bending output (up to 600 bends/hour)
In many cases, a Stierli bending machine is more cost-effective.
Very fast metal strip bending, tube and profils.
The max output depends on the thickness of the material.
- Technical advantages and cost benefits over vertical press brakes.
The Stierli standard bending press often has its nose ahead. More cost-effective, faster and more compact production is just one of the many arguments in favour of a Stierli bending machine. Find out more here. Our customers very often have a press brake from Trumpf, Bystronic, Amada, Blm or Boschert etc... in use. Our customers appreciate our machine because they can bend with high bending output, require little space and, above all, can produce many parts that a classic brake press is unable to do. Our fabrication solutions were delivered ni all over the world, in the USA, Europe, India, Russia, Australia, Middle East, Australia and South America. To buy a bending machine, we can provide our best support for your new projeckt and applications. In our groupe, there are machinery companies, that can provide local support.
The Stierli bending press is mainly used as a production machine with outstanding cost effectiveness. The long service life of a Stierli bending machine increases the cost effectiveness of this investment further.
However, there are also some companies that use the Stierli presses to make prototypes or small series, or for occasional uses.
Such companies appreciate the constant availability of the Stierli bending and straightening machine, as they do not have to depend on external production service providers and thus have greater flexibility, enabling them to offer services and supply products more quickly.
- Easy loading of the workpieces
The open design with large insertion width allows easy loading and parts handling. For large, heavy or long-sided parts, crane loading is an option.
Solutions with a robot, that inserts the parts are available. Together with a collaborative robot (or high speed robot with fences), we can offer autonome bending cell. (customized industrial production solutions) For busbar processing, we also can connect the unit togheter with a punching center.
- User-friendly control.
Our new digibend controls are designed in such a way that the operator can learn how to use them very quickly.
The manual control system is very popular and has been tried and tested in deployment over decades. The control system can be picked up in just a few minutes. The manual control system allows very precise working with its fine stroke setting.
The modern, powerful CNC control system (touch panel) has a clearly designed multiple line display. Graphical symbols support and facilitate the operating process.
Programming Systems + secondary Workstation software
Secondary Workstation software
Available for all control System.
The BendEdit is also a good tool for manual controls (HE) to determine the stop positions of the controlled cnc back gauge.
- Efficient creation of the bending programs with fast angle and leg length programming on secondary Workstations.
- Automatic calculation of the stop positions using the integrated material library and K-factors
- Calculation and display of the total length
- Direct graphical and full-scale 1: 1 live display of the programmed bending part. Bending simulation with stepwise analysis function and display of sequences. Automatic bending sequence calculation.
- Individual bending sequences can be set separately.
- Print bending program as a report (e.g. as working paper for operators) The report contains the required stop positions, distances, total length and the bending simulation step by step.
As an alternative to the already convenient machine programming system, the machine can be programmed using the “Metalix” system. (CAD / CAM)
The busbars can be created directly in Metalix. It is also possible to import DXF data. Metalix offers a direct interface with 3D systems such as SolidWorks, AutoCad Inventor, ePlan etc. The busbar drawing can be transferred directly into Metalix CAD/CAM. Processing including the holes, position of the bending lines and the length before bending is shown correctly. The bending or stamping program is created at the push of a button.
The CU-Profi professional CNC stamping centre from Boschert www.boschert.de is also operated with the same programming system. It is therefore possible to create the stamping and bending program for a busbar with one file. The programming work is kept to a minimum.
This combination creates a high-performance busbar machining centre that has the latest machine and programming technology. This combination represents the most economical and modern production capacity and is at the cutting edge of technology.
The description is similar to that for the Metalix programming system.
RADAN also offers the possibility of designing the busbars in 3D with the integrated 3D module. The customer does not need a separate 3D CAD system to benefit from the advantages of 3D design (programming speed and minimization of sources of error).
Connection to 3D CAD systems (AutoCad Inventor, SolidWorks, ePlan...)
Until now, conventional programming for bending parts with stamping work (including busbars) has required a lot of time. In combination with modern 3D CAD systems and the Metalix or Radan programming system, this time can be reduced dramatically. Possible sources of error are also eliminated in the process.
- Automatic processing directly from 3D.
The length before folding, position of the stamps and bending lines are calculated automatically and do not require further adjustment. Technical data about the material and tool is used in the background.
- Automatic creation of the bending program for the bending and stamping machine
- Significant time-saving in part programming.
- Excludes sources of error and increases process reliability
Modern busbar production is based increasingly on this production model.
Alternative bending concepts from Stierli-Bieger AG for metal bending press:
You can also use the navigation on our website to find other machines for bending, such as the radial bender with 360° driven rotary plate (without rollers and mandrel). This excellent circular angle bender works like a folding bending machine, round bending machine or a hand bender, but with control and strong electric drives (control manually not available). This type of bender is also suitable for thick or thin flat steels, sheets, profiles section, laser parts, tube and iron bars. Companies that use a roll bending machine very often also use our radial bending machine. The prices are similar to a medium-sized horizontal bending machine.
