EMO
Reseller contact information
The EMO machine is the steel knight in SERTOM’s stable.
It’s a hydraulic plate roll 3 rolls variable axis with an absolute pre-bending, designed to bend plates of medium/big thicknesses.
Born in 1976, it was able to revolutionize the plate rolls world.
Actually the SERTOM engineers, strong with a know how grown through years of testing, are able to adapt this technology to every customer request, such as
plates of special steel, pre-tension plate rolls, and the need of NC control.
The main feature that makes the EMO machine the most flexible plate roll on the market, is the peculiar geometry that allows to work from time to time as a 4 rolls machine, vertical or planetary guides, and this is the reason that most of the plate rolls manufacturers, thanks to the great success of the EMO, added in theirs machines range an EMO style machine.
All this thanks to the bottom rolls that move on a horizontal axis and independently from each other with variable steps, while the top roll motorized, moves on a vertical axis.
Due to the variable steps we can have:
1- great versatility (increasing the distance between the bottom rolls and maintaining the same thrust from the top roll, we are able to bend big thickness, decreasing such distance we are able to bend smaller thickness);
2- the plate is kept horizontal during the pre-bending process (therefore safer for the operator);
3- total dimensions of the machine decreased compared to a 4 roll machine, therefore no need for a pit up to certain size.
Maximum flexibility.
- Working flexibility, thanks to the variable geometry given by the possibility to move all 3 rolls independently and so to change any time the angle among them.
- Thanks to the top roll working like a “press”, the flat end is shorter than by a traditional 3 and 4 rolls
- The plate is worked always in horizontal position, granting more safety
- Thanks to its geometry, it doesn’t need foundations, also by medium-big dimensions
- By the same pre-bending capacities of standard 3 or 4 rolls, it reaches quite twice the rolling capacities
- Simultaneity of the movement granted by 2 separated hydraulic circuits, therefore max. thrust power and at the same time in rotation and in translation
- Possibility to tilt all 3 rolls
- Easy conical bending even by big thickness thanks to the top roll that is used like a “press”
