The characteristic of this series leveler iS that it has adopted two national patent technologies:group driving plate levelling machine ZL200420001176.0 and axial decelerating motor leveler ZL200520007514.6.Each top roll is driven by a set of decelerating motor.and every two lower rolls are driven by a set of dynamic system,so that the line speed of each roll iS consistent with sheet metal speed of the contacting part,and it has solved the problems existing in traditional transmission system,such as friction between sheet metal and roll surface.and mechanical interference problem in the system And the working roll adopts spherical roller bearings which have little friction resistance.so this series leveler has such advantages as high levelIing quality,Iittle noise,low energy consumption and environmental protection.compared with traditional levelers.

该系列矫平机的特色之处在于：采用分组驱动板材矫正机(ZL200420001176.0)和一种轴装式减速电机矫平机(ZL200520007514.6)两种国家专利技术，每根上辊由一套减速电机驱动，每两根下辊由一套动力系统驱动，从而使各辊的线速度与所接触部位的板料速度相一致，消除了传统传动系统存在的板料与辊面之间的摩擦和传动系统内部的机械干涉问题，同时由于工作辊的轴承均采用轧机用调心辊子轴承，摩擦阻力小，因此，该系列矫平机与传统矫平机相比，矫平质量高、噪音小、能耗低、节能环保。
