The company today

We work in Estonia for the whole world.

We offer customers both the machinery featured on the website and the development and production of equipment tailored to their needs. Machinery, conveyor lines, transportation and commercial equipment, and much more. We provide both development and manufacturing, as well as spare parts and service. We also offer upgrades for existing customer equipment.

Our main advantage is that we have qualifications and experience in all aspects related to such technology: in mechanics, hydraulics and pneumatics, electronics, and software. This allows us to determine optimal solutions in terms of simplicity and efficiency from the very beginning, rather than assembling expensive heterogeneous parts and connecting them somehow.

Experience shows that our equipment operates for decades without complaints, requiring only basic maintenance.

The founder of the company and the author of most technical and organizational solutions is Kuren Babajanants.

Education:

- Faculty of Mathematics and Mechanics, Leningrad State University

- Faculty of organizers of industrial production and construction of the Leningrad Engineering and Economic Institute

- Institute of Management and Economics, program "top manager" of the Academy of National Economy of the Russian Federation

Headed the Laboratory of Automation and Robotics of the Department of Advanced Technologies of the Physics Faculty of St. Petersburg State University

He began his manufacturing career by calculating the gravitational deformation of the mirror for a large optical telescope. He then transitioned to designing intricate mechanical structures and electronic control systems for their movement. From inception, he established mass production of tube bending machines, which are showcased on this website.

We work with result-oriented customers.

The customer can always solve their production problems by ordering the necessary equipment and technologies from us. To do this, they just need to discuss their task with us, sign a transparent contract, and receive an excellent product in any country in the world.

Geography of our deliveries

Our products work in many places and countries.

Here is a map, where arrows emanating from St. Petersburg (where the supplied equipment was produced) indicate the "extreme" points of its operation in different directions.

It is unrealistic to sketch with "circles" the individual places in which it works - half of the map would have been sketched.

A brief history of our company

1993 - 1994

We entered the market in 1993 as a completely independent company in Russia. We have never entered into any concerns or holdings, were not a subsidiary of anyone. Everything we did, we did 100% in the free market with our own skills and efforts.

Our first tube bending machine was made by us in 1994.
A photograph of that time has survived:
The force on the machine shaft is 1.5 tonn*m (15000 N*m).
The drive unit is a rotary hydraulic cylinder of our design and production.

The machine is still in operation. For all the time it was given to us for repairs once.

The next machine was ordered to us immediately after the first machine. We were recommended by our first customer. The force on the shaft of the second machine is 2.5 tonn*m (25000 N*m). This machine already has a full-fledged electronic control of our design (on two microcontrollers).

1995 - Windows-95 and Internet

In 1995, the operating system Windows-95 was released. And we immediately began to make machines that worked under Windows-95 control. Nobody agreed with us. Experts said that they “didn't do it”, that it is “very difficult”, that it “won’t work,” and so on.
But our machines worked, and they worked great.

It is interesting that we probably were the first company in the world, which used the control on industrial equipment via the Internet.
Unfortunately, in those years the Internet was an exotic thing in Russia - so it was unrealistic to persuade all customers to use this technology.

2000...

Around 2000, we started serial production of machine tools. The first serial machine was T-Twin (here are its modern versions). It was a breakthrough - nothing like this was done not only in Russia but in the world in general. The construction of the machine was extremely simple. At the same time, the machine provided ideal bending quality and fantastic productivity; the first models could bend up to four tubes at the same time.

From the very beginning, we have been making fully CNC controlled equipment. That is, all information from buttons, knobs, and pedals was read by our electronics and transmitted to the computer, which was already "in command" of the machine. It was very strange and unusual for that years. From those times, a funny "leaflet" remained - you can read it now..

At the same time (precisely for the design of T-Twin) we developed three completely innovative and unusual design principles. After a successful result, we apply these principles to all developments in mechanics, electronics, and software without exception. We'll write about them - follow our site.

T-Twin has been improved and released continuously to this day. Here are some of his photos:

2010 - 2024

By the beginning of the 2010s, we approached the creation of very complex machinery.

We created three models of machines - one of them was fully electric - for bending pipes up to a diameter of 90 mm using the most advanced bending technology at that time, with controlled boosting, each having 17 (!) controlled axes integrated with automated pipe measurement systems (both contact - FARO, and non-contact - AICON). The machines operated fully automatically; the operator only needed to input the drawing and the pipe into the machine, remove the finished part, place it in the measuring machine, which transmitted the results back to the machine. The machine itself analyzed deviations related to pipe springback and recalculated the entire product in 3D, then produced the perfectly bent pipe. All of this was done with very high precision - around two hundredths of a millimeter and a degree.

Note for those who are well versed in technological nuances:
For such work, we lacked a standard pipe model with a springback coefficient.
Therefore, we developed and introduced a bending model with three independent parameters - and the machines solved the corresponding systems of equations.

We have always been and remain primarily an engineering and manufacturing enterprise operating in a free market.

Over the years, we have developed and manufactured machines for bending pipes up to a diameter of 273 mm. Many products made from bent pipes that you, the reader of these lines, may see around you during the day (if you are in Russia), are most likely manufactured on machines produced by us.

We were apparently the first in the world to make: machines for vertical bending by winding, machines for parallel bending of multiple pipes, machines with a fixed pipe axis (which has now become the global "mainstream" for complex bending).

In addition, during our work, we have created many very serious things in various fields, from controller systems and sensors to production management systems, which had no analogs even close. When around 2014 we thought about buying an ERP system from the world's leading company for our small enterprise (which would have cost us around 500 thousand euros), we were amazed to see that our system was simpler - and could do much more. It already does at our production facility what this company was only talking about at the time as bright prospects.
