2-roller plate bending machine WyRoll 2R series

2-roll2 drive rollerselectric

Overview
The WyRoll 2R series from WEIYA is a two-roll plate rolling machine designed for zero straight edge forming, enabling single-pass seamless cylinders and higher throughput compared with conventional three-roll machines. Dual-drive synchronized rollers with CNC control deliver precise circular rolling for carbon steel, stainless steel (304/316) and aluminum plates across multiple models.

Key features

• Zero straight edge forming for single-pass seamless cylinders
• Dual heavy-duty drive rollers with symmetrical torque distribution and anti-slip surface treatment
• CNC synchronization with real-time roller position monitoring
• High repeatability and positioning accuracy (repeatability down to ±0.01 mm on higher-end models)
• Processing capability: carbon steel, stainless steel (304/316), aluminum, copper, brass (thickness depends on model)
• Optional modules for conical rolling, large-diameter support and temperature control for continuous production

Accessories & Modules

• Required modules
  • Dual Heavy-Duty Drive Rollers — hardened alloy steel rollers (HRC 58-62), anti-slip surface; integrated torque sensors available
  • CNC Control System — automatic diameter compensation, conical rolling programming, 3D roll bending simulation; offline CAD/CAM compatibility
  • High-Pressure Hydraulic Press Unit — servo pump driven with precision pressure control and integrated cooling
• Optional modules
  • Side & Overhead Support System — hydraulic supports for large-diameter or thin-plate rolling to reduce sag
  • Industrial Chiller — PID temperature control to prevent roller overheating during continuous operation
  • Auxiliary Roller Support — hydraulic positioning, multi-axis memory, non-marking urethane-coated rollers for oversize workpieces

Applications & Benefits

• Mass production of seamless cylinders and shells with tight circularity tolerances
• Suitable for automotive, shipbuilding, construction, furniture and aerospace components
• Faster setup and up to ~30% higher throughput versus comparable 3-roll machines
