MCB - FOUR ROLL

By Fabrication Equipment Supplies
  • 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

No need to pre-bend the two edges of the plate first, and then roll, as on any three roll.  

A cylinder can be rolled, including the pre-bending of both ends, feeding the plate forward through the rolls, one time only. The operator should find one only position for each side roll, to get part finished.

CNC CONTROLLED

It is controlled, in entry-level, by a user-friendly CNC, to roll parts in automatic mode. More powerful DAVI CNCs (the most advanced in the industry, until those selected by NASA), are self-programmable, without the need of experienced operators.

ACCURATE FEEDING

Both clamping rolls are powered, with two independent hydraulic motors, and they are braked hydraulically and safely, instead of using low efficiency, consumable brake linings common to other brands.

HORIZONTAL FEEDING

Plates are loaded horizontally to allow the use of an in-feed conveyor and automated loading and unloading systems. The machine, CNC controlled, becomes an automated un-manned rolling center, with a cycle time extremely short, ideal for high quantity productions.

DAVI EXCLUSIVE BENEFITS

SERVO-TRONIC

Servo-Tronic is more accurate than any previous hydraulic, electronic or mechanic (torsion bar) parallel system, and keeps the machine’s side and bottom clamping rolls parallel, even in case of electronic problems (less down-time), as it has a dual, independent but integrated, parallel control system (Davi Patent).

PLANETARY PREBENDING

It allows for excellent roundness, thanks to the Planetary movement of the side rolls (Davi patent), moving them to the center of the machine (the tightest geometry available), 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

Planetary Guides (friction-free, mill-scale-proof, Lubrication-less, Maintenance-free), Permanent Lubrication, Energy Saving, digital Roll by Wire and the dual Servo-Tronic parallel system (most Davi Patented), make it innovative, state-of-the-art, easy to be operated, highly productive, very accurate, reliable and maintenance-free.

ISO – MADE IN ITALY

ISO 9001:2008 certified, built with total quality, complying with tight ISO standards (today, a “must” in the market), it is engineered and built for high performance, in a distinguished design common to the most reputed “100% Made in Italy” products.

It also benefits from the professional mechanical “passion” of Promau’s local area, home of Ferrari, Maserati, Lamborghini, Ducati, ect., the most advanced Italian high-tech companies.
