Three-Roll Plate Bending Machine: Hydraulic Power, Optional NC Control and Support for Every Plate Size

Some workshops roll a handful of cylinders a week. Others run plate bending all day, with heavy sheets, large diameters and tight deadlines. The SBFM Three-Roll Plate Bending Machine, a hydraulic 3-cylinder roll bending machine coded 3R SBS, is designed to serve both. It bends thin or thick sheet metal into full circles, half circles and cones at the grade you need, and a menu of optional features lets you shape the machine around your own production.

Quick Product Facts

• Product: Three-Roll Plate Bending Machine, Hydraulic
• Product code: 3R SBS
• Manufacturer: SBFM Machinery, Konya, Türkiye
• Category: Sheet Metal Forming
• Process: Hydraulic roll bending of plates into full circles, half circles and cones
• Roll arrangement: Three rolls: one top roll and two bottom rolls
• Optional features: Digital display, NC control system, lift and side supporting arms

What Is a Hydraulic 3-Roll Plate Bending Machine?

A three-roll plate bending machine forms plate by three-point bending. Two bottom rolls carry and drive the plate, while the top roll presses down to set the curve. Hydraulic cylinders move the rolls with strong, smooth force, so each pass tightens the curve until the plate closes into a cylinder or settles into the arc or cone you need.

The design is compact, dependable and easy to service.

One Machine for Circles, Half Circles and Cones

Because the rolls can be positioned precisely, the same machine produces full circles, half circles and conical shapes. Thin sheet and thick plate both fit within the capacity of the model, so a single machine can follow your order book from light ducting to heavy tank shells.

Key Features and Benefits

• Three-roll design that is compact, robust and easy to operate
• Hydraulic roll movement for strong, smooth and adjustable force
• Full circles, half circles and cones on one machine
• Thin and thick sheet capability within the model capacity
• Rigid welded body that holds accuracy under heavy load
• Modular options so you pay only for what your work needs
• Easy operation that helps operators learn quickly and work safely

Optional Features That Fit the Machine to Your Shop

The machine can be extended with options that suit different jobs. A digital display shows roll positions clearly, so settings are easy to read and repeat. An NC control system stores bending data and brings more automation and consistency to repeat work. Side supporting arms hold wide or large-diameter plate so it does not sag or twist, and a lift helps handle heavy workpieces. Please confirm which options are available for your model.

Materials You Can Bend

The machine rolls carbon steel, stainless steel, aluminum and other bendable plate materials. Maximum thickness and width depend on the model and on the yield strength of the material, and harder grades reduce the thickness you can roll.

Applications

• Storage tanks, silos and hoppers
• Pressure vessels, boilers and heat exchangers
• Pipes, tubes and ducting made from rolled plate
• Chimneys, towers and steel structure components
• Shipbuilding and heavy fabrication
• HVAC, food and chemical process equipment

Tips for Perfect Rolling

Plan for the flat ends that three-roll machines leave at the plate edges by pre-bending in a press or leaving extra length to trim off. Keep the plate and rolls clean, because scale and chips mark the surface. Allow for springback, the slight return of the plate after bending, by rolling a little past the target and checking with a template. Bend gradually in several passes.

Part of a Complete Sheet Metal Forming Range

SBFM Machinery has built sheet metal forming machines in Konya since 1998. Alongside three-roll machines, our range includes two-roll and four-roll plate bending machines, hydraulic dishing presses, flanging machines, profile and pipe bending machines, polishing machines for dished heads and special corrugated and grooved rolls. A single partner can equip your workshop from shells to tank heads, rings and pipes.

Why Choose SBFM Machinery?

Machines are designed, cut, welded, machined, assembled and tested in our own facilities, and our quality policy rests on customer satisfaction. We believe we grow together with our customers, so we listen first and recommend the model that fits your work, not simply the largest one. Technical guidance and spare parts help keep your machine productive for years.

How to Choose the Right Machine

• Maximum plate thickness, width and material grade
• Smallest and largest cylinder diameters you need
• Whether you want NC control, digital display, lift or side arms
• Production volume and operator skill level
• Available floor space and power supply

Maintenance for Long Service Life

Keep the rolls clean, check hydraulic oil level and filters, and inspect hoses and fittings for leaks. Lubricate bearings and guides as described in the manual and protect the machine from scale and chips. A simple preventive routine keeps rolling accurate and reliable for many years.
