Plate Rolls with Planetary Swinging Arms 4HEP

4HEP: 4 rolls with Planetary technology

The 4HEP series of 4-roll synchronized bending rolls is latest evolution of a design developed in Faccin and tested by the most demanding operators in extreme environments for over 25 years. It combines power, reliability and precision in an exclusive package that makes it the state of the art in modern plate rolls.

To guarantee superior rolling quality and high repeatability of the products roundness, a closed loop structure together with the traditional ultra wide drop end ensures maximum rigidity of the machine against high longitudinal and traverse forces.

The traditional linear RGS design of the pinching roll guarantees higher pinch forces for superior quality pre-bending. In fact the pinch roll is supported by 4 independent bearings (2 on each side) and the bearing housing is two times larger for better lateral load absorption and guiding.

Once again – as already happened in the past with the rolls electronic balancing system and the drop end fixing system – the engineering improvements reached in the continuous R&D process are even in this case such a reference point to be imitated by other manufacturers.

We expect therefore that the innovative exclusive HFS system, which features an external mounting of the pivoting lateral hydraulic cylinders, fixed in their highest end as standard configuration on all medium and large sizes of 4HEP to ensure a greater closeness of the bending force application points, becomes soon a landmark in the machine tool industry.

The policy to exclusively offer first-class components has meant that all versions of numerical control systems available for 4HEP series are SIEMENS only and with the ability to use roller conveyors, automatic loading and unloading systems allows the creation of a fully-automatic line.

The 4HEP design assures the possibility to optimize the entire rolling cycle, working in one direction and in one pass, ensuring extreme safety and the capability of being handled totally by a single operator even if they are less experienced.

4HEP bending rolls with exclusive Siemens CNC designed and built by Faccin are the most reliable and modern solution available amongst all rolling machines with planetary technology available on the market today . The most appropriate and reasonable investment for high productivity requirements for rolling plates from 5 to 150mm thickness up to a useful length of 18000mm.
