Technical Advantages of HOGI 4-Roller Rolling Machines
Straight-Line Side Roller Pre-Bending: The side rollers move in a straight line to support efficient edge pre-bending before full cylinder rolling. This helps reduce the remaining flat edge and improves the roundness of the finished workpiece.
Four-Roller Clamping Stability: The upper and lower rollers hold the plate while side rollers form the radius. This configuration provides controlled material positioning during pre-bending and rolling, helping reduce plate slippage.
Full Servo CNC Option: The W12HG series uses full servo drive for thin sheet processing. CNC torque control can adjust clamping force according to sheet thickness and width, while the 4.2 kW configuration supports rolling speeds of approximately 10 m/min.
Hydraulic CNC Option: The HGW series is designed for heavier plate rolling. Hydraulic drive, digital control, hydraulic distribution valves and displacement sensors support synchronized upper and side roller movement during the rolling cycle.
Flexible Production Integration: The equipment can be configured as a stand-alone plate rolling machine or incorporated into a rolling, welding and handling production line for ducts, fan housings, tanks and cylindrical pipe components.
Typical Applications
Operating Considerations
Select the drive configuration by plate range: The W12HG full-servo model is suited to thin cold plate and stainless steel processing, while the HGW hydraulic model is intended for thicker stainless steel and carbon steel plate applications.
Confirm minimum rolling diameter before purchase: Minimum diameter depends on roller diameter, material, thickness and yield strength. The stated minimum values apply only to the listed reference conditions.
Match the machine to downstream operations: If parts will proceed to longitudinal seam welding, flange forming or automated handling, confirm workpiece transfer direction, cycle time and control interface during line planning.

Technical Principle — Four-Roller Plate Forming
A four-roller plate rolling machine uses an upper roller, a lower roller and two side rollers. The upper and lower rollers grip and position the sheet. The side rollers raise in a controlled path to pre-bend the leading and trailing plate edges, then continue forming the plate into the required cylindrical radius.
For the hydraulic CNC configuration, hydraulic distribution valves and displacement sensors coordinate the pressure roller and side rollers. This supports synchronized movement through the pre-bending and rolling cycle. For full-servo configurations, CNC-controlled servo torque can be used to adjust clamping force for the applicable plate width and thickness.
Configuration Selection Notes
- Choose full-servo CNC: For thin sheet, higher rolling speed, small cylinder diameters and compact production requirements within the W12HG model range.
- Choose hydraulic CNC: For thicker plate, wider material and heavier cylindrical forming within the HGW series capacity range.
- Confirm material yield strength: The stated specifications are based on a yield limit of ≤245 MPa. Higher-strength materials require separate engineering confirmation.
- Confirm final diameter: The minimum rolling diameter varies with material, thickness and the selected model’s roller diameters.
- Plan downstream handling: When integrating seam welding, loading or feeding systems, define workpiece transfer direction and line cycle requirements before finalizing the layout.

HOGI CNC 4-Roller Metal Plate Rolling Machine Video
What the Demonstration Helps You Evaluate
This video provides a visual reference for the HOGI four-roller plate rolling process and related cylindrical fabrication applications. It can help production teams evaluate equipment layout, plate movement, workpiece handling and the potential connection between rolling and downstream welding operations.
- Plate positioning: Observe how a four-roller arrangement supports plate clamping and controlled movement during the forming process.
- Pre-bending workflow: Review the relationship between side roller movement, edge pre-bending and final cylindrical forming.
- Rolling-line planning: Use the demonstration as a reference when considering how rolling equipment may connect to cutting, seam welding or material-handling stations.
- Application fit: Consider the process for HVAC duct sections, fan housings, tanks, cylindrical pipe components and other rolled sheet-metal parts.
Model Selection Before Project Planning
The video should be reviewed together with the machine specification page. The full-servo W12HG configuration and hydraulic HGW configuration have different processing ranges, roller diameters, drive methods, rolling speeds and minimum-diameter capabilities. Material grade, thickness, width, yield strength and required cylinder diameter should be confirmed before selecting a model.
Production Line Integration
HOGI can configure four-roller plate rolling equipment as a stand-alone solution or as part of a broader fabrication line. For projects that include coil feeding, plate cutting, cylindrical rolling, longitudinal seam welding and workpiece transfer, the full line layout should be planned around part size, required throughput and available floor space.
