It is a very important processing equipment. The working principle of the plate rolling machine is to use external forces such as hydraulic pressure and mechanical force to move the working rollers, thereby pressing or bending the sheet metal into shape. According to the rotational movement and position changes of working rollers of different shapes, round parts, arc parts, cylindrical parts and other parts can be processed.
