RAYMAX Plate Rolling Machine – Servo-Driven Pinch Roll for Precise Edge Pre-Bending Control

RAYMAX plate rolling machine features a servo-driven pinch roll that allows independent control of pinch pressure and roll position, enabling precise pre-bending of plate edges with digital repeatability. The CNC controller stores pinch pressure profiles for different materials. Maximum width 2000mm, thickness 16mm. The machine also includes a digital readout of roll gap. This plate rolling machine is used for high-tolerance applications such as boiler shells and autoclave cylinders where consistent pre-bend length is critical. RAYMAX provides a calibration procedure using test plates to verify pre-bend accuracy. A 2-year warranty covers the servo motor and drive.

Economical Three-Roller Design for General Sheet Shaping

RAYMAX plate rolling machine offers the W11 mechanical three-roller plate rolling machine, mainly used for rounding off plates from 4mm to 40mm thickness and 1500mm to 4000mm in length. It is a very affordable and economical plate rolling machine, the best choice for general fabrication shops and maintenance departments. The three-roller initial pinch type handles plates with hydraulic or mechanical force to shape flat sheets into accurate cylinders, achieving straightness deviations below 0.5mm per meter. RAYMAX plate rolling machine is ideal for pressure vessels, pipelines, storage tanks, boilers, wind power towers, and tunnel arches. The hardened steel rolls (HRC 52-55) resist wear when rolling carbon steel, stainless steel, and aluminum. RAYMAX provides a digital bending calculator to generate rolling parameters from customer drawings, reducing setup time by 50%.

Four-Roller Hydraulic Model for Pre-Bending Without Flat Ends

RAYMAX four-roller plate rolling machine is suitable for bending work of sheet metal, capable of rolling round, arc, and tapered workpieces within a certain range. The four-roller design features a hydraulic pinch roll that grips the plate edge with adjustable pressure, preventing slippage when rolling high-strength steel plates. It has a pre-bending function at the end of the board, eliminating flat sections and reducing welding preparation time by up to 40%. This is critical for pressure vessel shells where consistent roundness is essential for butt welding. The four-roller configuration pre-bends both ends in a single pass, saving time and improving accuracy. Maximum rolling width 4000mm, thickness 60mm for mild steel. RAYMAX plate rolling machine is the preferred choice for pressure vessel fabricators, oil storage tank manufacturers, and penstock producers.

Digital Roll Position Display for Repeatable Production

RAYMAX plate rolling machine features digital displays showing real-time roll position and bending angle, allowing operators to record and reproduce settings for standard product families. The W11S plate rolling machine features hydraulic lifting, mechanical horizontal movement, and centralized electrical control, supporting pre-bending, rolling, and leveling operations while saving material. Optional NC system control provides advanced automation for high-volume production. A digital readout shows the distance between rolls, which correlates to bending radius. RAYMAX includes a bending radius calculator software that generates rolling parameters from input diameter, material, and thickness. This plate rolling machine is used by companies that produce standard product lines such as air receiver tanks, manhole shells, and wind tower sections, ensuring consistent quality across batches.

A plate rolling machine is a fundamental piece of industrial equipment designed to continuously bend flat metal plates into cylindrical, conical, or custom-curved shapes through a process of plastic deformation. Unlike press brakes that perform linear bending, a plate rolling machine uses the principle of three-point bending, where the metal plate passes between rotating work rolls that apply controlled pressure to achieve the desired curvature. The machine operates by feeding the plate between a set of rolls—typically one upper roll and two lower rolls in a pyramid configuration, or four rolls in a more advanced design. As the rolls rotate, the upper roll presses down while the lower rolls provide rotational torque, causing the plate to undergo compression on the inner surface, tension on the outer surface, and a neutral axis in the middle where no deformation occurs. This process is repeated in multiple passes, gradually forming the plate into the required shape. RAYMAX, a leading sheet metal rolling machine manufacturer with 22 years of experience, produces W11 series three-roller and four-roller models designed for automotive, aviation, shipbuilding, and power industries. Our plate rolling machines are manufactured with all-steel welded frames that are stress-relieved through tempering and vibration treatment, ensuring long-term stability and resistance to deformation under heavy loads. The machine frames, assembly surfaces, and connection holes are machined after the welding process, guaranteeing perfect parallelism and positioning accuracy. Our range of machines addresses various thicknesses and types of materials, from thin-gauge aluminum to heavy-duty steel processing, with capacities ranging from 1mm to 200mm thickness. We hold CE and ISO9001 certifications and export to global markets, trusted by over 4,000 clients worldwide for reliable sheet metal processing equipment. Contact us to discuss the optimal plate rolling machine configuration for your specific material thickness and diameter requirements.

Frequently Asked Questions

What key functions does an ironworker machine combine?

An ironworker machine integrates punching, shearing, notching, and bending in a single setup. It can punch holes up to 32mm in diameter, shear 6-12mm steel plates, and achieve bending angles up to 135°, greatly reducing the need for separate machines.
Fiber laser welding is 4-10 times faster, produces a significantly smaller heat-affected zone (minimizing distortion), and offers better energy efficiency with lower consumable costs. The process also creates clean, spatter-free welds that often require no secondary finishing.
A fiber laser cutting machine can cut most metal materials including carbon steel, stainless steel, aluminum, copper, brass, and titanium alloys, with a maximum cutting thickness of up to 50mm for certain metals.
A CNC press brake achieves bending angle tolerances of ±0.1° and repeat positioning accuracy up to ±0.01mm through CNC automatic control, CAD drawing import, automatic angle compensation, and deflection compensation features.

RAYMAX four-roller plate rolling machine pre-bends both ends of the plate in a single pass, eliminating flat sections that previously caused weld mismatch for our pressure vessel shells. The hydraulic pinch roll grips the plate edge with adjustable pressure, preventing slippage when rolling high-strength steel. The pre-bending accuracy of ±0.5mm over 1m length has improved our welding fit-up significantly. The machine handles plates up to 3000mm width and 30mm thickness. The digital roll position display allows us to reproduce standard diameters consistently. RAYMAX's engineers provided comprehensive training on four-roller operation. The machine has reduced our welding preparation time by 40%. This plate rolling machine is the best investment we have made for our pressure vessel production line. The quality improvement is evident in every shell course.
