Working principle of the rolling process: The working of rolling is quite interesting but requires a skillful operator to use it. the process is achieved by stocking metal between some rotating rollers in the opposite direction. The gap between the rollers is smaller than the thickness of the part being worked.

The rolling process is a metalforming process, in which a stock of the material is passed between one or more pairs of rollers to reduce and maintain the uniform thickness. This process is mainly focused on the crosssection of the ingot or the metal which is forming. Using this process, we can reduce the thickness of the metal workpiece.
