TIGHTEST DIAMETERS ON THE MARKET
The side rolls, driven by the unique DAVI planetary guide technology, provides the necessary bending force achieving the tightest diameters per capacity on the market (1.1 of the top-roll) obtaining the highest accuracy due to the perfect parallelism offered by the patented Servo-Tronic© system.
NO LUBRICATION
Roll-by-wire means running the entire system through digital signals, instead of the many relays and contacts of the past.
​
The planetary guides installed on MCA machines are not affected by friction and mill scale therefore they don’t need any lubrication.
​
Great plate rolls for cone rolling with a very high angle and small diameters.
FULLY CUSTOMISABLE
MCA machines solutions can be fully customised to better support the most diverse production requirements and industrial sectors.
​
Compared to other technologies, 4-roll machines stand out for allowing fully CNC-automated production processes, significantly decreasing the reliance on operator’s skills and therefore making it the most suitable technology for mass-production.

MOST COMPACT, CLOSED FRAME
The frame constitutes, effectively, the backbone of the machine. The stress generated during plate forming must be withstood by this critical component and eventually, transmitted to the foundations. DAVI machines feature the most compact and closed frame on the market, which enables you to improve the rigidity of connection to the ground as well as machine stability, minimise deflections and displacement for the maximum, positioning accuracy of the rolls.
PENDULAR ARRANGEMENT
With the standard motorised top and bottom rolls and unlike other solutions available in the market, it offers bolted-rigid coupling of the gearbox structure to the machine frame, the DAVI exclusive pendular arrangement allows for swingable connection between the motor gearboxes and the frame.
IMPROVED MACHINE STABILITY
The frame constitutes, effectively, the backbone of the machine. The stress generated during plate forming must be withstood by this critical component and eventually, transmitted to the foundations. DAVI machines feature the most compact and closed frame on the market, which enables you to improve the rigidity of connection to the ground as well as machine stability, minimise deflections and displacement for the maximum, positioning accuracy of the rolls.
STRESS FREE TILTING
The DAVI pendular shaft-mounted gearbox configuration allows for stress-free tilting of the rolls up to 100 mm (4”) every 3 metres (10 feet) of roll length. The pendular gearbox arrangement allows for free deflection of all the rolls under the load, with limited stress on shaft-hub connection, maximising the bearings reliability and durability and a much higher tilting capacity for cone-forming.
