Rolling machines, metal-presses and welding machines are most commonly used for this. Metal is prepared for industrial machinery using separation processes by being rolled into sheets and then wrapped onto reels. Punching machines and machine tools are used to separate sheet metal. Cutting machines are used to process individual sheet metal.
