Detailed Design & Components

Standard accessories for W12 CNC Hydraulic Rolling Machine

Body Structure

The bodies of DURMAPRESS Plate Rolls are designed with FEM analysis to obtain a maximum strength and rigid structure. In this way, tensions that occur during bending are minimized to provide safer and longer machine life.

4-Roll Planetary Design

In this models, rolls are hardened to 50-60 HRC and crowned to compensate for deflection during rolling. They're polished to DIN Ck45 quality and can be extended for bending different profiles upon request.

Control Panel

Due to its mobility, the machine controls material rolling from all sides. The digital display on standard machines shows the present and maximum positions of the right and left rolls. The control panel can be customized with additional buttons for preferred optional features.

Linear Guides

The system uses linear guides, ensuring the rolling scales do not affect the system. This planetary system operates safely with minimal maintenance and downtime, maintaining a robust body even at small rolling diameters.

Rolling Momentum

The hydraulic motors and planetary reducers power the lower and upper rolls, ensuring efficient rolling. The planetary reducer connects directly to the roller shafts, transferring momentum without power loss. A hydraulic stopping brake enhances safety during pre-bending.

Electronic Part

All rolls are supported by spherical roller bearings, which can carry heavy loads and facilitate conical movements. These bearings operate with high precision and durability, even in challenging conditions. By reducing friction, they save energy, ensuring that the full power is used to shape the material.

Other Components

Top-Quality Accessories from Leading International Brands

Top and lateral support rack

Top and lateral support racks in plate rolling machines provide crucial support by preventing sagging and side deflection of large or thin plates during rolling, thereby enhancing rolling accuracy, improving product quality, and reducing operator effort for smoother, more efficient operation.

Material feeding table

The material feeding table for a plate rolling machine is engineered to enhance efficiency, precision, and safety by incorporating features such as automatic centering, servo-driven alignment, vacuum suction handling, and adjustable configurations to accommodate various plate sizes and shapes.

Why choose us？

Durmapress always adheres to the concept of putting customers first in the whole purchase experience, and continuously optimizes and innovates the production process to cater to the needs of all large, medium and small manufacturing companies.

What are Advantages of optional device？

Cone bending device

Cone bending with the W12 is simple and efficient. The bottom rolls are angled to form the cone shape, controlled by an electronic microprocessor (available on select models). The control system ensures precise return to parallel positioning after cone bending, maintaining accuracy and consistency in repeated operations.

Automatic loading and unloading system

Automatic loading and unloading systems improve efficiency, reduce manual handling risks, and ensure consistent, reliable operation. They help minimize errors, lower labor costs, and support continuous production while optimizing workspace utilization.

Top and lateral support rack for big diameter

The top and lateral support racks for large diameters enhance stability and precision during rolling. They prevent deformation and maintain the workpiece shape, ensuring high-quality results when processing large and heavy materials.

Fan cooled or water cooled

Fan- or water-cooled systems help maintain optimal operating temperatures, preventing overheating and ensuring stable performance. They also reduce heat-related wear, extending the lifespan of machine components.
