Advanced Plate Roll Bending Machine Design

A rolling machine (plate rolling machine or plate bender) is an industrial machine used to form flat sheet metal into curved shapes such as cylinders, cones, and arcs. It works by feeding the workpiece between rotating rollers—typically two bottom rolls and one top roll—which progressively bend the material. The curvature is controlled by adjusting the position of the top roll relative to the bottom rolls.

Our rolling machines can process mild steel, stainless steel, aluminum, copper, and other ductile metals. The forming capacity depends on material thickness, tensile strength, and plate width. Please refer to our capacity charts for specific material and thickness combinations.

Our CNC hydraulic rolling machines typically achieve ±0.5mm to ±1mm diameter accuracy with digital position feedback and closed-loop control. Cylindrical roundness and straightness are maintained through precision roll alignment and optional CNC programming. Manual models offer good repeatability with proper operator technique.

Yes. Conical forming is possible with cone rolling attachments or 4-roll machines with inclined roll capability. Our CNC models can store programs for different diameters and cone angles. Oval and special profile forming may require custom tooling—contact us to discuss your specific shape requirements.

Standard models typically ship within 4-8 weeks. Custom configurations or large-capacity machines may require longer lead times. All our rolling machines come with a comprehensive warranty covering major components. Extended warranty options are available.

We offer mechanical and hydraulic plate rolling machines in various configurations: 2-roll (pinch type), 3-roll (initial pinch, variable geometry, or pyramid type), and 4-roll machines. Our 4-roll models provide pre-bending capability without plate reversal. CNC hydraulic rolling machines with programmable control are available for high-precision and automated production.

Our rolling machine models typically handle plate thickness from 1mm to 100mm+ for mild steel, with plate widths from 1m to 4m or more. Minimum inside diameter capability varies by model—typically 1.2 to 2 times the top roll diameter. Contact us for specifications tailored to your production requirements.

2-roll machines use one top and one bottom roll for simple bending. 3-roll machines add flexibility—pyramid type has two bottom rolls and one top roll; variable geometry allows pre-bending with plate reversal. 4-roll machines have two bottom rolls and two side rolls, enabling pre-bending of both ends without turning the plate, reducing handling and improving efficiency.

Regular maintenance includes lubrication of roll bearings and guide ways, hydraulic oil changes (for hydraulic models), inspection of rolls for wear and surface damage, and verification of safety systems. We provide detailed maintenance schedules and operator training. Annual professional inspections and roll alignment checks are recommended.

Yes. We offer professional installation and commissioning, operator training on safe operation and CNC programming (where applicable), and comprehensive after-sales support including spare parts (rolls, seals, bearings, etc.) and technical assistance. Our global service network ensures prompt response when you need us.
