Profile and sheet metal straightening

Using the system of rollers, profile and sheet straighteners straighten the semi-finished products to the desired shape without changing their thickness. The semi-finished product is straightened permanently, so when it leaves the machine, its undesirable state and shape is not restored. The important technical parameters of the machines are: torque, bending force on each roller, hydraulic pump capacity and hydraulic system flowrate. The machines are powerful and can provide high-efficiency straightening in the production process.

ARKU FlatMaster 55

The servo-hydraulic roller leveller designed to straighten and release the internal tension of the mainly laser-cut and punched sheet metal parts. After precise and rapid straightening of the ARKU FlatMaster 55, the parts are in the next operations (welding, bending, etc.) processed faster, with higher reliability and high quality process. 

The machine concept bases on the use of strength mechanical structure and on the fast servo-hydraulic control of the distance between the upper and lower sets of feedback rolls. 

The roll diameters are small enough and the sets of support rolls support the working rolls firmly along their width, allowing processing the material of variable thickness. Despite the sudden changes in material thickness with each workpiece, the machine keeps its geometry and distance size constantly. 

Due to the hydraulic system, the negative effects of rapid and impact force changes are eliminated, preventing mechanical abrasion of the action elements and their distance.
