The rolling machine performs both primary and auxiliary movements during operation. The primary movement is typically achieved through the upward and downward movement of the work rolls, which includes rotation and bending, assisting the machine in processing the sheet material. The auxiliary movements involve operations such as loading and unloading during the processing, as well as the lifting and lowering of the upper roll, tilting actions, and flipping operations of the stand.

The process of processing sheets involves steps such as rolling, bending, edging, and mold pressing. Rolling is the first step, also known as rolling round, where the sheet material is subjected to external forces, causing the outer fibers to elongate and the inner fibers to shorten, with no change in the middle layer fibers. This results in a curved deformation of the sheet, enabling the formation of shapes like cylinders. The working principle of the rolling machine is based on this.

In cases where the cylinder radius is large, mechanical methods are typically used for rolling operations, with rolling machines being the equipment for such tasks. Of course, one could opt for diaphragm pressing or manual rolling, but in terms of efficiency, the use of rolling machines for rolling operations is highly efficient. When the cylinder radius is small, the process involves heating the sheet metal first, making it easier for the fibers to change after heating, followed by the rolling operation.
