Safety is a priority for us when designing and manufacturing our plate bending equipment, which is why our four-roll plate bending machine is equipped with interlock devices to prevent accidents during operation. With its comprehensive features, high precision, and user-friendly interface, our CNC plate benders are an ideal solution for modern CNC plate rolling requirement, offering both high efficiency and reliability in metal forming tasks.

With a rectilinear guide system, the forming rolls are transmitted and forced directly into the hydraulic cylinder. There are no load-bearing wear points or torsional stresses in the 4-roll plate rolling equipment interfering the roll parallelism and accuracy, which has contributed to a long service life, consistent rolling result, and convenient maintenance. The centerline of the forming roll is close to that of the pinch roll, allowing the flat areas associated with pre-bending to be small and consistent. In addition, Chaoli has regulated the direct-acting hydraulic cylinders for pre-bending to the maximum rolling capacity.

The rolls of the plate bending machine are independently driven by planetary gear drives, eliminating the complicated transmission systems which are not energy efficient. More than 98% of the created energy is delivered to the roll surface. Besides, clutches and complicated synchronization devices are also of no necessity.

Spherical roller bearings are extremely energy efficient, which have eliminated bushings and the necessary running tolerance. The energy loss among which 25-30 % is taken up by bronze bushings for overcoming the inherent friction is negligible.

Our 4-roll plate bending machine is widely used by industries looking for precision and versatility in rolling operations. Ideal for sectors such as energy, transportation, oil, petrochemicals, boiler manufacturing, shipbuilding, hydropower, and metal structures, this plate bender excels in creating perfect cylindrical, arc, conical, square, and various uniquely shaped workpieces. Its capability to handle a wide range of shapes makes it indispensable for projects requiring high precision and efficiency.
