Plate Rolling Machine FAQ:
What is plate rolling machine and how does it work?
A plate rolling machine, also known as a plate roll or plate bending machine, stands as a powerhouse within your workshop, offering unparalleled abilities to mold metal sheets. Think of the plate roll as a versatile tool that serves as a master craftsman, shaping metal with precision and finesse. It’s commonly used in various industries like manufacturing, construction, shipbuilding, and metalworking for creating cylinders, cones, pipes, and other curved structures from flat metal sheets.
When your metal sheets are fed into our plate rolling machine, they are carefully positioned between the two, three, or four rollers(2 roll bending machine, 3 roll bending machine, 4 roll bending machine). These rollers work in unison, allowing us to precisely control the metal’s form by adjusting their positions and exerting pressure. It’s similar to a skilled artisan meticulously crafting metal to meet specific design requirements.
Our plate rolling machine ensures your metal sheets adopt a distinct and customized shape, tailored to your precise specifications. Just as a tailor fits clothing to an individual’s measurements, our machine shapes the metal to your exact desires.

What is Heavy Plate Rolling Machine and what are BIT’s benefits?
A Heavy Plate Rolling Machine is a robust industrial machinery designed specifically for bending and shaping thick and heavy metal plates.
- Reliability: For BIT heavy plate rolling machines with heavy plate thicknesses greater than 6 inches, the upper roller main drive adopts a four-hydraulic motor converging structure.
Drives the upper roller to rotate through the hydraulic motor and the planetary reducer gearbox.
- Double-cavity cylinder: Standard model, short procurement cycle and stable and reliable quality; long service life of the cylinder and seals. It effectively simplifies the unload side structure, is safe and reliable, and can roll large-taper workpieces.
- Variable Geometry: The PRV variable-geometry plate roll flexibility makes it a suitable choice for medium to thick materials, say more than 1 in. thick.
Variable-geometry plate roll’s two bottom rolls can be positioned under the top roll at just the right spot to leave a minimal unbent flat for the material at hand.
- Linear Guided: Linear guided delivers at-par performance and flexibility at much lower costs, therefore ideal for medium-to-heavy duty rolling.
What do you need to prepare before buying a plate rolling machine?
The following parameters need to be provided: the material of the metal plate, such as carbon steel and stainless steel; yield strength; plate width; minimum bending radius; maximum bending radius. Workpiece shape.
- Material Type and Specifications: Determine the materials you’ll be working with, considering aspects like thickness, width, diameter, strength, and yield. These factors dictate the necessary pressure and the maximum and minimum diameter/width for the plate roller.
- Minimum Diameter Requirement: Calculate the minimum diameter required based on the thickest material to be worked upon. The 1.5 rule often applies, where the diameter rolled should be at least 1.5 times the top roll diameter. Understanding this and the material’s yield strength aids in selecting the appropriate plate roll.
- Round vs. Out-of-Round Rolling: Decide if you’ll only be rolling round objects or require special shapes. Utilizing a plate roll with a CNC control facilitates manipulating roll positions and speeds, necessary for shaping non-round objects like ovals or specialized shapes.
- Producing Large Diameters: Assess the size of the diameter you’ll be producing. Larger diameters might necessitate additional support, such as side supports or overhead support, to prevent back bending due to the material’s weight.
