How Does a Servo-electric Press Brake Work?


The way we are in today’s time, each industry is heavily influenced by current technology. Thanks to the enormous advancement in recent times, every industry has received new tools and equipment that have helped achieve giant accomplishments and progress. As business owners, it becomes mandatory for you to know and stay up-to-date about these latest technologies to get the best out of them.

Therefore, if you are in the manufacturing industry or have a fabricator business, it is important for you to know about your current technologies and tools and how they operate. On that note, in this article, we will shift our focus to Servo-Electric Press Brakes. We will take our time to understand what these machines are and learn the working of a Servo-Electric Press Brake. Therefore, if you are ready, let us get learning!

What Is A Servo-Electric Press Brake?

Press brakes are machines that can help you bend and manipulate metal sheets and plates. Given this ability, press brakes are primary tools in the manufacturing and fabricating industry.

However, earlier models of press brake machines were prone to loud noises and required large consumption of energy in order to provide results. Due to rising concerns for nature and the critical need to save resources, better alternatives were needed that would offer the same or better results with minimum resource consumption and lesser contribution to pollution.

To meet up these expectations, the Servo-Electric Press Brake was invented. Accurl’s new model of press brake operates on electricity, with no hydraulic support, and offers various advanced features. Thus, these are more eco-friendly, offer more accuracy and precision, and require less energy consumption.

Also, it helps reduce the production costs, as it is easy to operate, requires no out-of-the-way maintenance, and has features that help provide faster and accurate products.

How Does A Servo-Electric Press Brake Operate?

Now that we have a fair idea of what a Servo-Electric Press Brake is, we shall now move on to understanding the operations behind it. It is important to learn how a machine operates because that way, you will know how to utilize the machine efficiently and to its full potential.

Also, it will help you take care of the machine better to get long-term results. Therefore, let us take our time to understand the Servo-Electric Press Brake Working.

Usually, press brake machines have two main components whose movements bring about the desired results — the die and the punch. In some models, the die is fixed, whereas the punch is movable, whereas in other models the punch is fixed, and the die is made to move against it.

In either of the systems, the movable part is fueled by the energy and pressed against the fixed part with the desired metal or material in between the two. The die can be changed and fitted with various angles and shapes to bring about the desired manipulation on the metal.

In Accurl’s Electro Servo Press Brake, the movable part is fueled by electricity instead of hydraulic pressure, as in the traditional models. That is, the movable parts are fitted with two servo motors that generate the power to push it down against the fixed part, thus producing the desired effect.

There are several pulley systems attached to the servo motors that help distribute the pressure evenly along the length of the material so that accurate and precise bending takes place.

Additionally, Servo-Electric Press Brakes, like Accurl’s CNC Press Brake EURO PRO 4 ~ 6-Axis, have in-built CNC systems attached to them that help make precision bends and manipulation to the material. A CNC system (Computer Numerically Control System) is a system that allows you to feed your machine with the necessary adjustments you need on your material, and it will help direct the machine to give you the precise result.

CNC systems do not require you to manually handle the machine and yet give you extremely accurate and precise results. So, the way the process works is you feed in the necessary details in the CNC system.

The CNC system understands it and forwards the information to the machine and the servo motors, which then start applying the energy which makes the machine move in the desired manner. Hence, you get your desired manipulation and bends in your machine.

Why Opt For The Servo-Electric Press Brake?

We have now understood what press brake machines are, what Servo-Electric Press Brake machines are, and how they operate. While we are on the topic, we would like to shed some light on why Servo-Electric Press Brake machines are the talk of the market.

If you are opting to invest in it, you should know why doing so will help your business. While there are different types of press brakes out there, including the traditional hydraulic press brakes and innovative hybrid models, Servo-Electric Press Brakes, such as Accurl’s Servo Electrical CNC Press Brake eB Icon Series, are strongly recommended. Here are a few reasons why:

Less Power Consumption

First and foremost, Servo-Electric Press Brakes consume less energy as compared to traditional models. While Servo-Electric Press Brake does consume double the amount of energy to produce the same result as a hydraulic press brake, hydraulic press brakes need to run the entire day to be operational.

While Servo-Electric Press Brakes only need to run when needed. This naturally makes Servo-Electric Press Brake a better alternative as it consumes lesser power and has higher efficiency.

High Accuracy And Speed

Servo-Electric Press Brakes are naturally more accurate than other types of press brake machines. According to experts, Servo-Electric Press Brakes are accurate up to 1 micron while hydraulic press brakes are accurate up to 10.16 microns.

As for speed, Servo-Electric Press Brake has higher pending power and has faster output speed as compared to other traditional press brakes, making it the desirable alternative.

Smarter Alternatives

Servo-Electric Press Brakes are equipped with smart features, AI, and CNC systems that make it the smarter alternative. Therefore, you do not just get efficiency; you also get higher accuracy, better productivity with minimal input, and top-class results as compared to traditional press brakes.

Sustainable And Environmental Friendly

As businesses of modern times, it is your duty and responsibility to think about sustainability and preservation of natural resources. Servo-Electric Press Brakes are better alternatives in this case because, as mentioned earlier, they consume less energy and contribute less to pollution.

They are fuel-efficient and are comparatively quieter while functioning, which does not add to noise pollution. While traditional press brakes may be prone to oil leaks and spills, such factors are not a matter for Servo-Electric Press Brake, which adds to its eco-friendliness.


Last but not least, Servo-Electric Press Brakes are far more economical than their other counterparts. While hydraulic press brakes have higher maintenance costs due to frequent changes in oil, fluids, and filters and more managing seals and leaks, Servo-Electric Press Brakes are very economical.

Therefore, if you are wondering why you should invest in a Servo-Electric Press Brake, these are the precise reasons why it is a very good investment both in the short and long term.

So, that is all there is to know about Servo-Electric Press Brakes, how they operate and why they are the better alternative to their traditional counterparts.
