Roller leveling

Roller leveling is a bending process. The unleveled sheet metal part is deformed with a series of alternate bends. The alternate bends are created by passing the sheet between upper and lower sets of leveling rollers. The leveling rollers are offset by half the roller spacing in the direction of the travel. As a result, the sheet metal takes a wave-like path through the precision leveler. The wave should be greatest at the entry of the machine and smallest at the exit (comparable to a decaying sinusoidal curve). The elastic-plastic alternate bends and the constant decline of bending intensity thereby produce flat and nearly stress-free sheet metal parts.

Modern servo-hydraulic precision levelers as the ARKU FlatMaster® distinguish themselves from mechanical straighteners through following features:

  • In the case changing cross-sections different leveling forces occur in the machine. If the force in the machine alters, the machine FlatMaster® detects this and produces a counteracting force within fractions of a second. Consequently, The leveling gap is kept constant. A constant leveling gap is important to produce constantly good and reproducible leveling results - especially, when it comes to oval forms and cut-out metal parts.
  • Leveling rollers are the tools of roller levelers. Regular cleaning of the leveling rolls is essential to constantly good leveling results. Consequently, modern precision levelers as the FlatMaster® are equipped with a quick-change system for the leveling rollers. The quick-change feature permits a quick and easy change and thorough cleaning of the rollers and the leveling unit. Thereby, downtimes due to maintenance are reduced significantly.
  • Modern precision levelers possess a graphic display with user-friendly handling of the control. The control also includes setting memory and a suggestion system. Leveling know-how is stored in control and  available to everyone. Once achieved leveling results thus are reproducible at any time.

Modern precision levelers as the FlatMaster® are set-up to deliver constantly good leveling results in a highly efficient way. Cost-effectiveness and high leveling quality distinguish these machine tools.
