The HMS3R Series W11 is a mechanical-drive, three-roller symmetrical plate rolling machine built for everyday workshop use. The upper roller rises and lowers precisely in the center between the two lower rollers through a screw-nut and worm-gear system. The two lower rollers are the powered drive rolls — they turn and feed the plate while delivering consistent torque through the gearbox gears.

Once the cylinder or cone is formed, the upper roller can be quickly disengaged so the finished workpiece slides out without struggle. Optional motorized side rolls are available when you need to handle different sheet thicknesses or materials.

The design is deliberately simple: fewer complex hydraulics mean easier maintenance, lower running costs, and reliable performance shift after shift. Combined with high-strength 42CrMo forged rollers, the machine delivers accurate, repeatable bends at a price point that makes sense for job shops and fabricators who need production capability without overspending.

Key Advantages of CAMT W11-3 Plate Bending Machine

42CrMo Solid Forged Rollers – High Hardness, Low Deformation

The working rollers are made from solid 42CrMo alloy steel forgings, quenched and tempered, then intermediate-frequency hardened to HRC47-58. In daily production the roller surface resists wear and indentation, so even after long runs of medium-to-thick plate the roundness stays consistent and rework caused by roller deformation is significantly reduced.

Upper Roller Disengages Quickly for Easy Unloading

After rolling is finished, the upper roller can be disengaged and lifted so the finished cylinder or cone slides out freely. One operator can remove even large-diameter or long workpieces without forcing or flipping them, cutting handling time and reducing safety risks on the shop floor.

Lower Rolls Are the Powered Drive – Steady Plate Feeding

Both lower rollers are directly driven by the gearbox and rotate in sync, delivering consistent torque. The plate feeds smoothly without slipping or drifting, so both thin and medium-thick sheets receive even bending and the risk of edge waves or excessive ovality is greatly reduced.

Pure Mechanical Drive – Lower Maintenance Cost

The machine uses a screw-nut and worm-gear mechanical elevation system instead of complex hydraulic circuits and seals. Routine care is limited to regular lubrication, failure points are few, and ordinary workshop staff can handle most repairs. Over time, spare-parts and downtime costs stay noticeably lower than hydraulic models.

Optional Motorized Side Rolls for Wider Plate Range

Motorized side rolls can be added to the standard machine for pre-bending and for handling different thicknesses and materials. When rolling cones or irregular plates, the side rolls help control the plate edge, reduce manual assistance, and improve first-pass success rate.

Schneider Electric Components – Stable Running, Fewer Stops

The electrical system uses Schneider brand components with clean, well-organized wiring. Motors start smoothly and control response stays reliable in daily production, cutting unexpected downtime caused by electrical faults and helping the workshop maintain continuous operation.

Working Roller

The working rollers are the heart of the machine. Their quality directly decides how long the machine lasts and how accurate every bend will be.

We use solid 42CrMo alloy steel forgings for every roller. After forging and rough machining, the rollers are quenched and tempered to HB240–300. Then the working surface receives intermediate-frequency hardening to HRC47–58, following the JB/ZG4289-86 roll steel standard.

In real production this means the roller surface stays hard and resists indentation even when you run medium-to-thick plate day after day. Roundness holds steady, wear stays low, and you spend less time replacing rollers or correcting out-of-round parts.

Electrical System of Rolling Machine

Safety & Stability

The electrical system uses Schneider Electric components throughout. Wiring is laid out cleanly and logically, so faults are easier to find and less likely to occur in the first place.

Motors start and run smoothly with low noise. Control response stays consistent during daily production, which means fewer unexpected stops and less downtime on the shop floor. The overall setup protects both the operator and the machine’s critical parts, while the robust motor design helps the machine maintain stable performance over long service life.

Electrical System of Rolling Machine

Stepper Motor ⇨ Planetary Gearbox ⇨ Working Roll

Roller Rotation

Power flows from a stepper motor through a planetary gearbox directly to the working rolls. The three-roll symmetrical layout keeps contact pressure evenly distributed across the plate, giving strong and consistent traction during rolling.

The upper roll moves vertically to apply the bending force, while the two lower rolls turn forward and backward to feed the material through the machine. Self-aligning bearings on the upper roll run with low resistance. They support the roll firmly and keep the sheet from slipping sideways, so the plate tracks straight and the finished cylinder stays true.

How the Machine Rolls Plate

Roller Rotation

The upper roller rises and lowers exactly in the center between the two bottom rollers. This movement is driven by a screw-nut and worm-gear system, giving the operator precise control over the bending force.

The two bottom rollers are the main drive rolls. They receive power through the gearbox output gear that meshes directly with the roller gears, delivering steady torque to the plate as it is fed through the machine.

The overall design stays compact and mechanical, so daily operation and routine maintenance remain straightforward. An extended shaft is also available, allowing the same machine to bend profiles such as angles and channels when needed.

FAQs When Purchase W11-3 Roller Plate Rolling Machine

What is the maximum plate thickness and width this machine can roll?
Depending on the model, maximum rolling thickness ranges from 4 mm to 40 mm, and maximum width from 1,500 mm to 3,000 mm. We will recommend the most suitable model based on the plate thickness and width you use most often.
The standard machine is mainly for rolling cylinders and has limited pre-bending ability. If you need better pre-bending results, motorized side rolls can be added. This significantly reduces the flat ends and improves the final shape.
Yes. The machine can roll carbon steel, stainless steel, and aluminum plates. When rolling stainless steel, we recommend reducing the rolling speed and using rollers with the appropriate hardness. We will provide specific process advice based on your material.
Standard models are usually ready for shipment within 25–40 working days. Machines with side rolls, special roller hardness, or customized width normally take 45–60 working days. Exact timing will be confirmed after the order is placed.
We provide remote video guidance for installation and commissioning, plus long-term supply of main wear parts. Critical spare parts (roller bearings, gears, electrical components) are kept in stock and can be shipped by air in urgent cases. English-speaking technical support is available for overseas customers.
We can supply the machine with CE-compliant configuration and the necessary documentation to meet most European import requirements. The exact certification scope and document list can be confirmed before ordering.
Taking the common W11-12×2500 model as an example, the main machine occupies roughly 4.5 m × 2.2 m. Including front/rear working and loading space, we recommend reserving at least 8 m × 4 m. Power supply is normally 380 V / 50 Hz, with main motor power between 7.5 kW and 11 kW, depending on the selected model.
The standard symmetrical three-roller machine is mainly designed for cylinders. If you regularly need to roll cones, adding side rolls and using a tilted upper-roll method can produce moderate taper. For high-precision or large-taper requirements, we will recommend a more suitable machine type.
The machine carries a 12-month warranty from the date of shipment or 2,000 operating hours, whichever comes first. The warranty covers parts replacement due to manufacturing defects. Wear parts (such as bearings and seals) and damage caused by improper operation are excluded.
The mechanical structure is relatively straightforward. Operators with previous plate-rolling experience can usually become productive within 1–2 days. We provide a detailed operation manual and remote video training that focuses on upper-roller control, plate alignment, and common troubleshooting, so new operators can also learn quickly.
