    1.What is Slip Rolling Machine?

    A slip roller, also known as a slip rolling machine or sheet metal roller is the equipment widely used in the metal fabrication industry. As its name suggests, the slip rolling machine bends and rolls the sheet metal.

    Slip Rolling Machine

    Slip Roller Machine

    Since the sheet metal itself is comprised of different shapes, sizes, and qualities. So, it all comes down to an effective device or equipment that could roll or bend the sheet of any given specification. Slip roller is deemed a versatile device to serve the purpose.

    The working principle of the device is as simple as the machine itself. The rollers exert hydraulic pressure or mechanical force to roll, cut, or bend the sheet metal. Slip roller creates arc-shaped, round, conical, oval, cylindrical, and cut-out sheet metal pieces. The shape or form of the final piece depends on the dimensions of sheet metal as well as the specifications of the machine.

    The slip rolling machine comes in a multi-rollers design to enable its usage for sheet metal of varying dimensions. The conical or cylindrical-shaped bent sheet metal finds its large usage in the commercial industry and household applications.

    The slip rolling machines come in several models and variants depending on the set parameters such as the number of rollers, yield limit & rolling speed, diameters of upper & lower rollers, thickness & width of the rolling plate, and motor power, etc.

    2. What are the Types of Slip Rolling Machines?

    As it was established in the previous section, slip rolling machines are featured in a variety of types based on the number of rolls. They’re usually categorized into 3 main types:

    6. How does Slip Rolling Machine Work?

    The working procedure of a slip rolling machine is pretty simple. The machine is designed on the basic principle of rolling, bending, and cutting. For a 3-roll slip machine, the plain concept of rotational motion and position change alongside exertion of hydraulic pressure or external mechanical force upon the main and supportive rollers is exploited for plate deformation.

    The procedure is divided into two basic parts, i.e., motion and rolling:

    Motion

    The main motion and auxiliary motion carry out the basic processing task. The main motion refers to the rotation of both the rollers while the auxiliary motion is all about lifting and overturning the top roller. The hydraulic pressure or mechanical force moves the upper roller while the lower two rollers are moved by the friction force produced between the main roller and sheet metal plate.

    Rolling

    Rolling

    Rolling

    A pre-bending process is implied before the final rolling because a length at either side of the plate doesn’t bend. Chances of misalignment are always there if one fails to keep the plate parallel/in-line with the roller. The curved or rolled workpiece is then loaded on the roller again for correction to ensure maximum uniformity and smoothness.

    7. Manual or Electric Slip Rolling Machine, Which One is Right for Your Workshop?

    Much has been said about the capabilities, features, and advantages of electric & manual rolling machines. The previous sections fully explain the working and limitations of manual and electric slip rolling machines. Here’s a quick summary of the previous discussions in this regard.
