CNC Four-Roller Plate Rolling Machine

A four-roller machine uses two side rolls plus top and bottom rolls to grip and bend plate without repositioning, enabling pre-bending of both leading and trailing edges in one pass. Three-roll machines typically require plate flipping or separate pre-bending steps, making four-roll systems faster and more consistent for production environments.

Capacity varies by model and configuration within the Piranha and Bertsch EVO product lines, ranging from lighter-duty duty-cycle work to heavier industrial plate bending. Contact Piranha's technical support team with your specific plate thickness, width, and material requirements for a tailored machine recommendation.

CNC control automates roll positioning and bending sequences, improving repeatability, reducing operator error, and speeding up setup for different plate dimensions. It enables autonomous operation, consistent curvature across production runs, and easier handling of complex or varied bending jobs compared to manual roll adjustment.

Yes, four-roll designs like the Bertsch EVO series are built to grip the plate securely between four rolls, allowing both leading and trailing edges to be pre-bent without removing or flipping the material. This reduces cycle time and improves edge-to-edge curvature accuracy.

These machines serve trailer and truck body manufacturers, power and transformer producers, structural steel fabricators, switchgear builders, and electrical enclosure manufacturers. Any operation requiring curved or cylindrical plate components for tanks, housings, structural members, or enclosures benefits from four-roll bending capability.

Piranha offers technical support for unique bending roll requirements, phone-based sales assistance, downloadable brochures, and an online configurator for shop-building and pricing. Customers are encouraged to contact Piranha directly for shipping, warranty, and detailed service inquiries specific to their plate roller needs.
