Rolling machines are mechanical machines used in the processing of metals and other materials. They use a combination of pressure, heat and friction to form metals into specific shapes and sizes. There are many types of rolling machines, each suited for a specific application.
Rolling machines are based on either two-high or four-high designs. In two-high machines, one roll rotates in the same direction, while the other roll rotates in the opposite direction. This creates a “rolling” effect between the two rolls, enabling the repeated shaping of the metal.
In a four-high unit, two rolls rotate in the same direction and two rolls rotate in the opposite direction. This design enables greater pressure to be applied to the metal during the rolling process.
Angle rolling machines are a type of rolling machine used for creating curved and angled shapes. Angle rolls are often used in the production of cylinders, which require having the outer edges in the same plane as the axis of rotation. Rolling machines used for this type of shaping are most often four-high machines.
Radial rolling machines are used for forming circular or cylindrical components. They achieve this by having two rolls move in the same direction, rotating the material as it passes through the gap. This type of rolling machine is often used when components have a large outside diameter and thick walls.
Flat rolling machines are commonly used for producing stock material with a smooth surface and a consistent cross-sectional shape. This type of roll utilizes a two-high design and is used for the production of plates, strips and sheets.
Sendzimir rolling mills are especially designed for ultra-precise rolling for the production of thin-gauge pieces. This type of rolling machine uses two sets of rolls that are arranged in a vertical configuration. The upper set of rolls is designed for providing a fine finish and a soft reduction of the material, while the lower set of rolls can be used for creating a larger reduction.
Reversing rolling machines use two sets of rolls that are arranged in a horizontal configuration. This type of rolling machine is especially useful for forging and rolling processes. The machines are capable of processing hot or cold materials.
Universal rolling machines are a combination of both reversing and flat rolling machines. These machines utilize a four-high design and the ability to rapidly switch between reversing and flat rolling processes. This allows for faster production of complex pieces.
Planetary rolling machines are used for the production of special-shaped pieces. This type of rolling machine utilizes six or seven rolls that are arranged in a circular configuration. The rolls are arranged in pairs with one moving in the same direction and the other moving in the opposite direction. This motion enables the production of very complex parts.
Finally, there is the Skin-Pass Rolling machine, which is used for smoothing the surface of metal materials. This type of rolling machine uses two rolls that rotate in the same direction, applying light pressure to the material. This results in a fine, even finish.
No matter the type of rolling machine you require, there is a perfect one available for your application. All different types of rolling machines function differently, so it is important to choose the machine that is best suited for your specific needs.
