The machine is mainly used for the roll bending processing of aluminum composite panel, pure aluminum plate, stainless steel board and steel bar.  The NC machine thoroughly solves the problems of only driving the upper roller, and the difficulty of rolling thinner stave and can realize greater  declivity of the upper roller and side roller through the change of roller and then roll conical barrel with huger coning; it is with clear operation  interface and simple and convenient but precise operation. Therefore, it is one kind of product which can make you obtain high production efficiency,  reliability and competitiveness.      

     Three-roller numerical controlled machine is the most innovative machine in the market at present, and it is especially suitable for the heavy loading  work of rolling thickness bar. Very thick plate can be rolled only by increasing the distance between the lower side rollers. The fact has proved that  straightway shorter than any others produced by any three-roller rolling machine can be obtained through numerical control software  produced by our company in pre-bending of flexible shaft. It possesses many advantages compared with other similar three-roller rolling  machines.Any end of two lower side rollers can go up and down separately; it’s convenient to bend taper and ellipse shape. The oil cylinder controls the three rollers independently, the hydraulic motor drives gear box as three rollers linkage, and the top roller will adjust the rotating speed to match the two lower rollers as per material thickness. It’s convenient to set the straight line of two ends, arc length, and radius by CNC control system.         

     Four-roller hydraulic numerical controlled rolling machine has the function of double-end pre-bending. It is the machine with the best performance in  the international market; it has advantages not possessed by any other machine; the operator only needs determining the position of the side roller,  and it will begin to make the fore-end pre-bending of bar material automatically with shortest straightway left; unlike single-side pre-bending rolling  machine which needs the working procedures of sheet material moving out,U-turn, and re-feeding, etc, the four-roller hydraulic numerical controlled  rolling machine can finish all the procedures only by passing once.Any end of two lower side rollers and bottom roller can go up and down separately; the bottom roller is below the top roller, the accuracy is very high, it can bend many different radius arc on one panel.The oil cylinder controls the three rollers independently, the hydraulic motor drives gear box as three rollers linkage, and the top roller will adjust the rotating speed to match the two lower rollers as per material thickness, the bottom roller is driven to rotate together with top roller. It’s convenient to set the straight line of two ends, arc length, and radius by CNC control system.
