A rolling machine is a device used to shape and form materials, typically metal or plastic, into desired profiles or thicknesses. It operates by passing the material through a set of rollers that apply pressure, allowing for precise adjustments in shape and size. Rolling machines are commonly used in manufacturing processes, such as creating sheets, plates, or tubes. These machines come in various types, including sheet metal rolling machines and tube rolling machines, each designed for specific applications. They are essential in industries like construction, automotive, and aerospace, where accurate material shaping is crucial for product quality and performance.
