Machine engineering

Based on many years of experience, we decided to make a series of NC and CNC-controlled three-roller bending machines, entirely designed and made by our team of engineers. The project was aiming at involving local and national companies and suppliers of parts and components. Thanks to this, today we can present a truly Polish machine with the features and capabilities at the level of the world’s best manufacturers.

The PrimeARC 50 CNC model is the first one in the series of three-roller bending machines produced by us. We are currently carrying out design and assembly work concerning the following models:

  • PrimeARC 80 CNC with two lower forming rollers with a roller diameter of 80mm,
  • PrimeARC 60 CNC with two lower forming rollers with a roller diameter of 60mm,
  • PrimeARC 40 CNC with an upper pressure roller with a roller diameter of 40mm.

Our aim goes beyond the models mentioned above and will be successively introduced into production.

Three-roller bending machine

– PrimeArc 50 CNC model

The bending machine is designed for forming metal materials of various cross-sections into regular and irregular shapes of arcs and straight sections. Forming is done by moving the material between the rollers with simultaneous pressure of the forming roller, which position determines the obtained bending radius.

The machine is dedicated to forming material of various shapes: thin- and thick-walled pipes, flat bars, rods as well as open and closed profiles. By forming the material, we can achieve various shapes of produced elements: arcs, circles or spirals with irregular and variable radii.

Machine structure

The structure of the presented machine allows you to work in a vertical and horizontal position, depending on the user’s preferences. Feeding of the material is carried out by an electric motor with a reducer and a set of gears in order to distribute the power feed to all rollers. The system is equipped with an inverter that allows you to change the engine speed and, consequently, the feed speed f the material. In addition, the upper roller drive system uses a clutch to compensate the rotational speed of the rollers.

The 100% of structure of the machine was designed and made in Poland in accordance with applicable EU safety standards and regulations, which is confirmed by the CE declaration of conformity attached to the machine.

Control of the bending machine

The machine functions and operations are controlled from a mobile desktop with foot pedals responsible for the direction of material movement in manual mode, buttons on the control desk and a 10” Mitsubishi HMI touchscreen operator panel with built-in memory that allows you to save programs and machine operating parameters.

Navigation of the individual panel functions is intuitive and simple. The basic functionality is provided by the manual mode and the buttons for the movement of the forming rolls. The main function and the greatest advantage of the software is the automatic mode that allows you to repeat the previously saved sequence of movements of both axes. This mode enables the repetitive execution of geometrically complex shapes with the operator’s participation limited to loading the material and extracting the finished element.
