Whenever repeatability, productivity and ease of use are of essence, the 4-roll is the technology of choice. In a 4-roll machine, latest development of the rolling technology, the bottom roll clamps the plate guaranteeing a perfect control over its position throughout the whole forming process. The side rolls, actuated by the unique DAVI planetary guides technology, provide the necessary bending force achieving the tightest diameters per capacity on the market (1.1 of the top-roll) obtaining the highest accuracy thanks to the perfect parallelism offered by the patented Servo-Tronic© system. Compared to other technologies, 4-roll machines stand out for allowing fully CNC-automated production processes, significantly decreasing the reliance on operators’ skills and, hence, making it the most suitable tech for mass-production.
The Davi MCA 4-roll system is the latest in rolling technology. The bottom roll clamps the plate for precise positioning throughout forming, while the side rolls, driven by DAVI’s unique planetary guides, deliver the bending force needed to achieve the tightest diameters
