Baileigh Four Roll Plate Bending Machine PR-10500-4 by Baileigh is a professional-grade four-roll plate bending solution engineered for high-volume, precision metal fabrication. Designed to handle 1/2" mild steel at a full 120" (10-foot) working length, this machine delivers fast, accurate cylinder and cone rolling in a single pass - eliminating the need to reverse the plate and dramatically reducing setup time on the shop floor.

Key Features

• 1/2" mild steel capacity and 120" (10-foot) length for large-scale plate rolling work
• Large 10 hp motor runs on 480-volt 3-phase power and includes conical bending system for versatile cone and cylinder fabrication
• All 4 forming rolls are hardened and polished with 2 central driven rolls for long-lasting, consistent performance
• Dual hydraulic motors and high-efficiency planetary gearboxes directly rotate the 2 driven rolls for powerful, reliable torque transmission
• Front rolls have independent hydraulic lifters that go in the orbital pattern, allowing precise pre-bending and full edge-to-edge rolling in one direction
• Stabilizer torsion bar system keeps front rolls parallel to the top roll, ensuring uniform bend geometry across the full plate length
• Plate is always pinched during the rolling cycle, so there's no chance to lose the position - maintaining part accuracy throughout the entire process
• Conveniently movable operator console with control panel and toggles on the console make it simple to control the roll movement from the optimal vantage point
• 2 DROs on the control panel show the front and back roll positions for repeatability, enabling consistent reproduction of bend settings across multiple parts
• Hydraulic system for material removal: yoke on top roll drops, allowing the roll to lift so finished cylinders and cones can be easily extracted

Frequently Asked Questions

Can this machine pre-bend the leading and trailing edges of a plate without repositioning?

Yes. The front rolls have independent hydraulic lifters that go in the orbital pattern, allowing the leading edge to be pre-bent and the body and trailing edge to be rolled all in one direction and in one pass - no need to remove and reinsert the plate.

How do operators ensure consistent, repeatable bends from part to part?

The machine is equipped with 2 DROs on the control panel that show the front and back roll positions. These digital readouts allow operators to record and re-enter precise settings, making it straightforward to reproduce identical bends across multiple workpieces.

What prevents the plate from slipping or losing its position during the rolling cycle?

The plate is always pinched during the rolling cycle, so there's no chance to lose the position. This constant clamping action between the central driven rolls maintains positional control throughout the entire rolling operation.

How is a finished rolled cylinder or cone removed from the machine?

The machine features a hydraulic system for material removal: the yoke on the top roll drops, allowing the roll to lift. This opens the roll gap so that completed cylinders and cones can be slid off the rolls easily without the need for additional lifting equipment or awkward manual extraction.
