This machine tool is a special roller-type metal sheet leveling equipment, which is usually composed of power, host and electrical control parts.

Using the working principle of multi-roll, the plate is repeatedly deformed between the upper and lower leveling rolls to eliminate stress and achieve the purpose of leveling. A rigid support roller (wheel) is set outside the upper and lower rows of work rolls to form a four-fold roll assembly structure. The flatness of sheet metal can be obviously improved and the quality of workpiece can be improved by leveling with this machine. It can work independently and be used for leveling single sheet; It can also be equipped with uncoiling and feeding in the front of the machine, and shearing, stacking and online mechanism in the back. It can be connected into a production line with complete performance through the control system to level and cut the metal coil.
