W12 Series 4-Roll CNC Plate Rolling Machine
Product Overview
The SLM W12 Series is a state-of-the-art 4-roll CNC plate rolling machine engineered for maximum productivity and extreme precision. Unlike traditional 3-roll models, the 4-roll configuration allows for "one-pass" forming, where pre-bending and cylindrical rolling are completed in a single direction. This 4-roll CNC plate rolling machine is the ultimate solution for high-volume production environments, such as wind tower manufacturing, pressure vessel fabrication, and large-scale tank construction.
Key Features
- One-Pass Forming Efficiency: Our 4-roll CNC plate rolling machine completes pre-bending and main rolling without flipping the plate, reducing handling time by up to 40%.
- Advanced CNC Intelligence: Integrated with a high-end CNC touch-screen system, allowing for automated rolling programs and real-time monitoring of roller positions.
- Superior Pre-bending: The unique clamping force between the top and bottom rollers ensures the shortest possible flat ends, significantly reducing material waste.
- Heavy-Duty 42CrMo Rollers: Forged alloy steel rollers undergo induction hardening and tempering to ensure long-term wear resistance and structural integrity.
- Hydraulic Synchronization: Features high-precision hydraulic valves and sensors to ensure perfect parallelism of the side rollers during heavy-duty operations.
Working Principle
In this 4-roll CNC plate rolling machine, the top roller is fixed while the bottom roller moves vertically to clamp the plate securely. The two side rollers (lateral rollers) move on inclined or planetary guides to perform the pre-bending and determine the rolling radius. This geometry provides the best control over the plate throughout the entire bending cycle, ensuring perfect roundness and high repeatability.
