4 Rolls
Hydraulic Sheet Metal Bending Machine
Using a sophisticated and powerful hydraulic system, the 4-Roll Hydraulic Bending Machine is characterized by great safety and precision in the bending process. With the clamping pressure between the lower and upper roll, the plate is constantly supported, especially during the complex pre-bending operation. The symmetrical arrangement of the side rolls enables pre-bending on both sides without removing the sheet. The bending operation is made with correct positioning of the side rolls to create the proper radius.
