4-Roll plate rolling machine for thin material
DAVI’s MCA series is a specialized four-roll sheet metal rolling machine solution designed for companies that require high precision, repeatability, and full automation in sheet metal bending.
Main features
- The 4-roller pressure technology allows complete control of the sheet position throughout the process, thanks to the lower roller that “clamps” the sheet.
- The side rolls with DAVI’s patented Planetary Guides technology provide the required bending force and ensure the narrowest possible cylinder diameter in relation to the machine’s capacity.
- The patented Servo Tronic© system ensures perfect parallelism of the rolls, guaranteeing precision and stability.
- The machine is designed for fully CNC automated production processes, reducing dependence on operator skills and making it ideal for mass production.
Technology & Productivity
The MCA series combines innovative design and cutting-edge technologies to achieve high productivity and precision:
- •It allows for a small cycle diameter, which means effective shaping even of significant curves.
- Servo Tronic and Planetary Guides control ensures consistent quality despite multiple repetitions and demanding designs.
- The emphasis on automation (CNC) means faster cycle times, fewer errors, and greater production efficiency.
Scope of Application
The MCA machine is suitable for companies that process metal sheets into cylinders or curved shapes and require:
- full control of the rolling process & high repeatability,
- the ability to process small to medium thickness sheet metal in continuous production,
- use in industries such as HVAC, metal construction, boats, agricultural applications, etc.
Technical Specifications
