W12-120x4000 CNC 4-Roll Plate Rolling Machine | EZHONG, Hubei, China

EZHONG W12-120x4000 CNC Four-Roll Plate Rolling Machine – Siemens CNC, Hot and Cold Rolling

The EZHONG W12-120x4000 is a full hydraulic CNC four-roll plate rolling machine for heavy plate up to 120 mm thick and 4,000 mm wide. It pre-bends plate ends up to 100 mm and rolls the complete shell in a single feed without turning the plate, leaving the shortest possible straight edge thanks to EZHONG's double-roll full-drive design. Controlled by a Siemens CNC system and capable of both cold and hot rolling, it's built for high-accuracy, high-productivity work in wind tower, pressure vessel, boiler and shipbuilding fabrication.

Why Choose a Four-Roll Machine?

• The plate is clamped between the top and bottom rolls throughout rolling, so it can't slip
• The two side rolls do the bending, allowing both ends to be pre-bent without removing or turning the plate
• Clamping close to the plate edge gives shorter flat ends than most three-roll machines
• Fixed plate positioning makes four-roll machines well suited to CNC programming and automation
• Faster cycle times for production work with repeat sizes

Frequently Asked Questions

• What is the maximum plate size? 120 mm thick and 4,000 mm wide, or 100 mm when pre-bending.
• What's the difference between a 3-roll and a 4-roll machine? A four-roll machine clamps the plate between the top and bottom rolls, so both ends can be pre-bent without turning the plate, straight edges are shorter and the process is easier to automate.
• Can it roll hot plate? Yes. It's designed for both cold and hot rolling.
• Can it roll cones? Yes. The rolls adjust and tilt for cone bending.
• What control system does it use? A Siemens CNC system with an independent mobile console.
• How much space does it need? Approx. 10,000 × 5,157 × 5,170 mm, plus room for feeding tables, supports and a heavy foundation.
• What should I send for a quotation? Plate material and yield strength, thickness and width, minimum rolling diameter, whether you need hot rolling or cone rolling, and your local voltage and frequency.
