XW11S-140x4500 CNC 3-Roll Plate Rolling Machine | EZHONG, Hubei, China

EZHONG XW11S-140x4500 CNC Three-Roll Plate Rolling Machine – Wide, Energy-Efficient Heavy Plate Rolling

The EZHONG XW11S-140x4500 is a CNC three-roll plate rolling machine built for wide, thick plate. It rolls steel up to 140 mm thick and 4,500 mm wide, and pre-bends plate ends up to 125 mm, completing end pre-bending and full shell rolling in a single feed without turning the plate. EZHONG's patented dual-drive system powers each lower roll separately, which cuts friction, noise and energy use while allowing a smaller main motor. With its in-house CNC system controlling roll position, levelling and cone tilt, it's well suited to wind tower, pressure vessel, shipbuilding and heavy structural fabrication.

What Makes This Machine Different

• Patented dual drive: Each lower roll has its own drive system, eliminating the sliding friction, vibration and wear caused by shared mechanical drives
• Rolling-mill bearings: Low-friction roller bearings on the work rolls further reduce energy use and noise
• Smaller main motor: Lower friction means less power is needed for the same bending capacity
• Integrated cylinder design: Patented cylinders sit within the bed for a compact, rigid frame and a smaller footprint
• Patented cone rolling device: Rolls cones with a smaller small-end diameter than conventional machines
• Simple foundation: An integral chassis keeps foundation work straightforward

Frequently Asked Questions

• What is the maximum plate size? 140 mm thick and 4,500 mm wide, or 125 mm when pre-bending.
• Why is it more energy efficient? Each lower roll has its own drive and the rolls run on low-friction bearings, so less power is lost to friction and a smaller main motor can be used.
• Can it roll cones? Yes. EZHONG's patented cone rolling device allows cones with a small end diameter.
• What shapes can it form? Cylinders (O-shapes), U-shapes, multi-radius sections and cones.
• What does the CNC system control? Upper roll lifting and levelling, cone tilt and lower roll movement, with program storage and fault alarms.
• Does it need a complex foundation? No. The integral chassis keeps the foundation simple.
• What should I send for a quotation? Plate material and yield strength, thickness and width, minimum rolling diameter, cone requirements, and your local voltage and frequency.
