MCB - FOUR ROLL

RANGE
The most advanced machines to roll plates from 15-20 mm (5/8 – 3/4 inch), up to 80-100 mm (3 – 4 inch) thick and more. Accurate, easy, intuitive and fast (up to 6 meters – 20ft per minute), it is the most high-tech in “high productive mid-heavy application” in the market.

ONE PHASE CYCLE
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. Once the correct position of the side rolls are determined, the plate is rolled successfully.
CNC CONTROLLED
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.

ACCURATE FEEDING
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.

HORIZONTAL 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.

DAVI EXCLUSIVE BENEFITS

SERVO-TRONIC
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.

PLANETARY PREBENDING
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 TECHNOLOGY
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.

ISO – MADE IN ITALY
Davi is proud to say that all of the plate rolls produced are ""100% Made in Italy"", producing machines that comply with the tight ISO 9001:2008 certification standards which are a MUST in today's competitive production environments. Like it's Italian high-tech neighbors such as Ferrari, Maserati, Lamborghini and Ducati etc., Davi benefits from the engineering ""passion"" of it's local area to build plate rolls with the most technological advancements in the market.
