C-beam machine punching machine is broken: one belonging to C steel machine, punching machine to achieve a cut one. Machines for sheet metal roller leveling equipment. Usually consists of power, the host and electrical control components. The use of multi-roll works, the plate material in the upper and lower flat rolls between correction repetitive deformation, stress relief, to achieve the purpose of leveling. The upper and lower work rolls outward, provided rigid support rollers (wheels), set of rollers constituting the quadruple-type structure. Sheet through the machine leveling, can significantly improve its flat state, improve the quality of the workpiece. Can work independently for leveling monolithic sheet; also available at the front of the machine configuration uncoiling, cited material, cut back configuration, stack materials and online agencies, through the performance of the control system connected into complete production lines for metal coils were leveling, slitting.
