Under the condition of large elastic-plstic bending, no mater how different the original bending degree, the CNC precision leveling machine uses the "Bauschinger effect" of the material to bend the plate repeatedly, gradually reduce the bending deflection, and gradually change the origina curvature into a single curvature, and finally level it to achieve the leveling accuracy required by the process.
After a series of alternating bending, the sheet metal is controlled by the motor and the PLC to accurately control the lower pressure of each leveling drum,elminating the internal stress, and fundamentally solving the unsatisfactory leveling effect caused by the different stress in each part of the sheet metal, thus achieving high precision leveling.
