Why Choose the W12CNC 20x2000 4 Roll Plate Rolling Machine?
Four-roll construction combines plate clamping, pre-bending, alignment and rolling in a practical hydraulic forming process.
20 mm Plate Rolling Capacity
The machine is specified for steel plate up to 20 mm thickness under the rated material conditions, providing a practical solution for medium-duty industrial rolling.
16 mm Pre-Bending Capacity
Integrated pre-bending helps reduce remaining straight edges and supports more efficient cylindrical component production without requiring a separate pre-bending process.
Four-Roll Plate Clamping
The lower roll works with the upper roll to clamp the plate while the side rolls position and form the material, supporting stable feeding and pre-bending.
Horizontal Plate Feeding
Four-roll operation allows horizontal plate feeding, simplifying workpiece loading compared with processes that require inclined plate entry.
Hydraulic Rolling Drive
Hydraulic motor and planetary reduction drive provide torque for roll rotation while hydraulic cylinders control movement of the lower and side rolls.
PLC Controlled Operation
PLC-based control supports practical machine operation, roll positioning and repeatable production for industrial plate rolling applications.

How the W12CNC Four-Roll Plate Rolling Process Works
Four-roll plate rolling combines material clamping, alignment, pre-bending and cylindrical forming within one machine configuration.
1. Plate Feeding and Clamping
The plate is fed horizontally between the upper and lower rolls. The lower roll moves upward to clamp the material against the upper roll and establish stable plate positioning.
2. Plate Alignment
Side-roll positioning helps align the plate before rolling. Correct alignment is important for controlling cylinder geometry and reducing skew during forming.
3. Edge Pre-Bending
The plate remains clamped while the side roll moves upward to bend the plate edge. This integrated process helps reduce the remaining straight section at each end.
4. Cylinder Rolling
The driven upper roll rotates the plate while hydraulic positioning of the side rolls controls forming until the required curved or cylindrical shape is achieved.
Heavy-Duty Four-Roll Structure for Plate Forming
The W12CNC-20x2000 uses four working rolls consisting of one upper roll, one lower roll and two side rolls. The upper roll remains in position and provides the primary rotational drive.
Hydraulic cylinders control movement of the lower and side rolls. This arrangement supports clamping, pre-bending and rolling while keeping the plate under controlled positioning during the forming cycle.
PLC Controlled Hydraulic Plate Rolling Operation
The control system supports machine movement, roll positioning and practical production operation for repeated plate rolling processes.
Roll Position Control
Position information for the lower and side rolls helps the operator manage forming settings and reproduce required machine positions.
Hydraulic Motion Control
Hydraulic cylinders control the lower roll, both side rolls and the drop-end mechanism for the rolling and unloading sequence.
Production Parameter Storage
CNC/PLC control supports practical management of rolling parameters for repeated workpieces and production jobs.

W12CNC 20x2000 4 Roll Plate Rolling Machine Buying Guide
Plate rolling machine selection should be based on material, thickness, plate width, minimum rolling diameter and production requirements rather than model size alone.
Plate Material
Tell us whether the workpiece is carbon steel, stainless steel or another material. Yield strength directly affects required rolling capacity.
Maximum Plate Thickness
Provide maximum rolling thickness and maximum required pre-bending thickness so the machine can be evaluated against the most demanding workpiece.
Plate Width
Maximum plate width should be provided because required machine capacity changes according to the width of material being rolled.
Required Cylinder Diameter
The required inside or outside rolling diameter is one of the most important parameters when selecting a plate rolling machine.
Workpiece Drawing
A drawing helps confirm material dimensions, finished diameter, forming requirements and whether the selected machine is suitable for the production process.
Voltage and Destination
Provide workshop voltage, frequency and destination country or port before final electrical and export configuration is confirmed.
Is a 20 mm Four-Roll Plate Rolling Machine Right for Your Project?
Buyers searching for a 20mm plate rolling machine, CNC 4 roll plate rolling machine or hydraulic plate roller should compare machines according to actual workpiece data.
The W12CNC-20x2000 is rated for a maximum plate thickness of 20 mm and maximum pre-bending thickness of 16 mm under the specified material conditions. Plate strength, width, target rolling diameter and processing method can change the actual capacity required for a project.
Four-roll machines can be attractive when production requires horizontal material feeding, integrated pre-bending and efficient cylindrical forming. The plate can remain clamped during positioning and pre-bending, reducing the need for repeated manual plate handling.
Before ordering, send Hong Forging Machinery your material grade, yield strength, maximum thickness, plate width, required finished diameter and workpiece drawing. These parameters allow the rolling application to be reviewed before final machine configuration.
