MCA - FOUR ROLL

DAVI 4 ROLL PLATE ROLL

DAVI MCA – FOUR ROLL PLATE ROLL

RANGE
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.

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

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

DAVI 4 ROLL FEEDING:

ACCURATE FEEDING
Both clamping rolls are powered, with two independent hydraulic motors, and they are braked hydraulically, 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 4 ROLL PLATE ROLL 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 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.
  • DAVI AUTOMATION
    DAVI is the only manufacturer with an inside R&D, a team of experts, that engineer and realize the automation and the CNC that manage all its rolls.
  • DAVI R&D
    DAVI R&D has developed a new engineering and manufacturing philosophy, removing completely all the previous several electrical connections starting from the electric cabinet and going though the entire machine.
  • DAVI CNCs
    DAVI CNCs are user-friendly and “self-programming” (the most important help to the operator, even without experience), available to any customer, according with its range of activity and application.
