The four-fold precision leveling machine achieves the leveling effect by rolling and pressing multiple sets of rollers of the leveling machine. Four-fold high-precision leveling machine adopts support rollers between the upper and lower rows of leveling work rolls and support bearings (wheels) to form a double-layered upper and lower row, and a total of four-fold roller group structure; the force distribution of the leveling rollers Uniformity, good structural rigidity, small deflection of work rolls, high leveling precision, stroke harmonic attenuation straightening, fundamentally solve common leveling unevenness, easy to produce roll marks, workpiece collapse angle, sickle It can solve problems such as bending, improve the correction accuracy of the plate, and has a wide range of applications.
