CNC 3-Roll Plate Rolling Machine for Sheet Metal Bending
Multi-Shape CNC Roll Forming: Engineered with an advanced PLC and servo numerical control system, capable of rolling circular, oval/racetrack, rounded triangle, rounded square, and polygon sheet metal profiles in a single automated process.
High-Rigidity 40Cr Heat-Treated Rollers: Three solid alloy steel rollers (standard φ85 mm diameter) undergo precision quenching and tempering to withstand continuous bending loads without deflection or surface wear.
Overview & CNC Multi-Shape Bending
The CNC 3-Roll Plate Rolling Machine (W11GCNC & W11G Series) represents a breakthrough in versatile sheet metal curving and roll forming. Designed for modern HVAC ducting, exhaust silencers, chimney pipes, and structural metal fabrication, it integrates precision servo control with a three-roller asymmetrical bending mechanism.
Equipped with high-performance 40Cr quenched and tempered rollers and an intuitive touchscreen PLC console, this machine breaks the limitation of traditional circular-only rollers, enabling automated one-pass rolling for complex non-circular profiles including oval, flat-oval racetrack, rounded triangle, rounded square, and polygon shapes.
Geometric Flexibility & Mechanical Engineering
- Supported Profile Shapes: Perfect forming for round cylinders, flat-oval racetrack tubes, rounded triangles, soft-corner rectangles, and multi-faceted polygon shells.
- Solid 40Cr Quenched Rollers: All three roller shafts are forged from high-grade 40Cr alloy steel, hardened and precision-ground to guarantee high dimensional roundness and zero deflection.
- Servo CNC Positioning System: The synchronized servo motor and screw adjustment drive the side roller travel with micro-metric precision, ensuring repeatable bending angles and seam matching.
- Quick Disengaging Drop End: The manual release latch and tilt-out upper roller enable rapid, unobstructed removal of completely closed cylindrical workpieces.
Heavy-Duty Box-Frame Machine (W11G Series)
For thicker steel plates up to 6 mm and heavy-duty ventilation ducts, the W11G Heavy-Duty Series provides an integrated full-width enclosed box frame with vibration-damping cross-mesh steel panels.
Powered by a robust 3.0 kW primary drive motor and a dedicated 1.5 kW auxiliary lifting motor, it delivers substantial bending torque and steady feeding speed across sheets up to 2020 mm in width.
