RAYMAX Metal Rolling Machine – Overload Protection & Roll Hardness HRC 55 for Daily High-Tonnage Use

RAYMAX metal rolling machine is built for daily heavy use in steel service centers and large fabrication shops, with induction-hardened rollers (HRC 55-58) that resist wear and galling when rolling abrasive materials like hot-rolled carbon steel and weathering steel. The machine includes a hydraulic overload protection system that automatically stops the drive if torque exceeds safe limits, preventing roll breakage. Rolling speeds are adjustable from 2 m/min to 6 m/min, allowing operators to balance productivity and surface finish. Typical applications include large storage tanks, penstocks, and tunnel lining segments. With more than 4000 machines installed globally, RAYMAX’s metal rolling machines are known for their ruggedness and ease of maintenance.

Why choose us?

Versatile Material Processing for Carbon Steel, Stainless Steel, Aluminum

RAYMAX metal rolling machine can roll various materials including carbon steel, stainless steel, aluminum, copper, and alloy metals. Our rolling machines work on sheet metals such as steel, aluminum sheet, and stainless steel sheet as long as the thickness is targeted for your machine production. The three-roll design applies either hydraulic or mechanical force to shape flat sheets into accurate cylinders, with adjustable precision levels from ±0.1mm to ±0.5mm to match different industry requirements—high precision for aviation parts, standard precision for automotive components. Applications include pressure vessels, storage tanks, pipes, boiler components, and tunnel arches. Backed by ISO9001 certification, RAYMAX metal rolling machines ensure consistent quality and performance for demanding industrial metal processing tasks.

Heavy-Duty Construction for Continuous Industrial Use

RAYMAX metal rolling machines are made with high-grade materials and go through rigid quality control to ensure they can be treated as heavy-duty machines. The induction-hardened rollers (HRC 55-58) resist wear and galling when rolling abrasive materials like hot-rolled carbon steel and weathering steel. Rolling speeds are infinitely variable from 1 to 8 m/min via a potentiometer. Capacities reach up to 4000mm width and 40mm thickness for structural steel. This metal rolling machine is used in bridge fabrication, wind tower manufacturing, and heavy equipment production. RAYMAX provides operator training videos and a digital maintenance logbook with every machine, ensuring long-term reliability. With over 4,000 machines installed globally since 2002, RAYMAX's metal rolling machines are known for their ruggedness and ease of maintenance.

Optional CNC Control for Advanced Automation

RAYMAX metal rolling machine offers optional NC/CNC system control for advanced automation, reducing operator intervention and improving production consistency. The CNC system stores up to 50 rolling programs (diameter, material grade, thickness) for repeatable production. An integrated digital inclinometer shows the bending angle in real time. The closed-loop pressure control system monitors hydraulic pressure 100 times per second and adjusts roll position to maintain constant bending force, essential for rolling thin-wall cylinders without ovality. RAYMAX provides a software utility to transfer recipes between multiple machines via USB stick, ensuring consistency across production lines. This metal rolling machine is ideal for companies that produce standard product families and want to upgrade from manual to automated rolling operations.

Springback compensation is a critical capability of modern CNC metal rolling machines, addressing the tendency of metal to partially return to its original shape after the bending force is released. Springback occurs because metal has elastic as well as plastic properties; when the plate is rolled, it deforms plastically, but when the force is removed, the material recovers elastically, causing the final curvature to be larger (less curved) than the shape formed by the rolls. The amount of springback depends on material type, yield strength, thickness, and bend radius. CNC rolling machines manage springback compensation through predictive algorithms, real-time feedback systems, and controlled over-bending techniques to counteract the elastic recovery of metal after deformation. The CNC system incorporates material compensation algorithms that calculate adjustments based on the type of metal, thickness, yield strength, and elastic modulus. These algorithms automatically modify the rolling force and geometry as the material is being processed, ensuring that the material’s final shape remains true to the desired specifications. Advanced systems use real-time sensors to measure curvature during the rolling process, feeding data back to the controller for immediate adjustment of roll position and pressure. This closed-loop control enables the machine to compensate for variations in material properties within the same batch, reducing scrap rates and improving production speed by 20–25%. A CNC rolling machine with advanced springback compensation can reduce material waste by up to 15%. Automated deflection compensation systems maintain angular deviation below 0.5° across long plates, ensuring consistent geometry even under high loads. Modern CNC interfaces eliminate 70% of manual calculation, reducing operator dependency and improving first-part accuracy. Our metal rolling machines feature advanced springback compensation algorithms integrated with the CNC control system, enabling precise forming of high-strength materials and reducing trial-and-error scrap. Contact our applications team to discuss springback compensation approaches optimized for your specific material types and production requirements.

Frequently Asked Questions

What tonnage range do RAYMAX press brake machines cover?

RAYMAX press brake machines are available with bending force capacities from 40 tons up to 2,000 tons, with working lengths ranging from 1600mm to 12,000mm, enabling them to handle everything from small precision parts to heavy plate bending.
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 shearing machines achieve cutting accuracy of ±0.05mm, which is 10 times faster and more precise than manual cutting methods, delivering clean, straight edges essential for automotive, aerospace, and construction applications.
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.

As a small ornamental ironwork shop, we couldn't justify a fully automated rolling machine. RAYMAX offered an affordable manual three-roll model that meets our needs perfectly. The machine handles 1000mm width and 8mm thickness for our handrail and arch bending work. The three rolls are driven simultaneously for uniform material flow. The rolling speed is infinitely adjustable via potentiometer. The manual roll release lever allows removal of finished rings without tools. The machine is straightforward to operate, and our staff learned it in a day. RAYMAX provided a laminated quick-reference card with bending force vs. thickness attached to the machine frame. The machine has been reliable for over a year. For small shops with limited budget, this metal rolling machine delivers good value. The build quality is impressive for the price point.
