MCA – 4 Roll


Product Details

Davi’s MCA line features an innovative and exclusive design to roll plates up to ½ inch thick. Intuitive, accurate, and fast, this is the most high-tech plate roll for “light gauge” in the market.

The MCA has a distinct advantage over three roll designs; it can roll cylinders in a single motion having to pre-bend the two edges of the plate. Davi also utilizes a permanent lubrication system, and Servo-tronic parallel system creating the most maintenance free and reliable roll on the market.

Davi rolls are “100% Made in Italy” and comply with the highest ISO 9002:2008 certification standards. To nearly eliminate the possibility of the plate slipping, DAVI’s MAV used three independent hydraulic motors and gearboxes.

Innovative and exclusive in design, to roll plate up to 10-15 mm (1/2 inch) thick. Accurate, fast, easy and intuitive, it is the most high-tech plate roll for “light gauge” in the market.

Unlike on a three roll plate rolling machine, there is no need to pre-bend the two edges of the plate first and then roll the cylinder. A cylinder can be rolled, including the pre-bending of both ends, feeding the plate forward through the rolls in a single motion.

The operator needs to only find the correct position of the side rolls to successfully roll the plate.

Different choices of CNC controls are available, from an entry-level, user-friendly CNC to roll parts in automatic mode or more powerful and advanced DAVI CNC controls in the industry which can be self-programmable reducing the need of the most experienced plate roll operator.

Unlike other brands using brake linings that wear out, Davi incorporates the safety of automatic and hydraulic assisted braking for both clamping rolls to ensure accurate plate feeding.

Plates are loaded horizontally to allow the use of an in-feed conveyor and automated loading and unloading systems. The CNC controlled plate roll then becomes an automated un-manned rolling center greatly reducing cycle times, ideal for high quantity production runs.


The patented, state-of-the-art Servo-Tronic synchronized roll parallel control uses hydraulic and electronic systems simultaneously for the most accurate parallel system on the market over other brands using just hydraulic, mechanical (torsion bar) or electronic systems.

The Davi patented Planetary Swing Guide technology wraps the side rolls towards the center of the machine’s top roll to allow the tightest geometry available in the market compared to the inclined linear guides of other brands that, especially on large diameters, move farther away from the central roll and the plate clamping.

Davi uses only the most state-of-the-art technology, integrating digital Roll by Wire, permanent lubrication and dual Servo-tronic parallel system allowing for ease of operation to produce quality parts accurately and reliably and ensuring the most maintenance-free plate roll on the market today.
