Best Rolls Parallelism thanks to Patented SERVO-TRONIC System
The rolls movement is actuated by hydraulic cylinders installed at the two ends of the machine. The patented Servo-Tronic© system, actuated by DAVI exclusive and fast-responding roll-by-wire control system architecture, guarantees the machine’s rolls parallelism at all times thanks to its dual, independent but integrated, parallelism control system. This system features dedicated pumping groups and circuits guaranteeing that each cylinder receives oil at the very same pressure and mass flow, with electro-valves for fine-tuning only. This way, even in case of electronics failure, the rolls parallelism is hydraulically and mechanically maintained and the machine can keep operating with excellent results. The Servo-Tronic© allows for: maximum accuracy of the rolls positioning; limited reliance on electronics with reduced downtimes in case of its failure; best geometrical tolerances on the workpiece; automatic compensation for unbalanced loads.

Great Operability and Maintainability thanks to the New Machine Design
The improved design of the machine allows for increased operability during the whole process, provisioning: free deflection of all the rolls under load, with limited stress on shaft-hub connection to the benefit of bearings reliability and durability; compact frames to easily eject the formed workpiece and to make extreme cones with no interference. Moreover, the planetary guides technology significantly reduces the required machine maintenance, thanks to: no need for regular lubrication with friction free movements (permanently lubricated bearings); maximum energy efficiency and durability with eliminated risk of guides wearing on accumulated mill-scale.

Machine Ready for Upgrade thanks to Built-in Provision for Retrofitting
With more than 50 years of experience designing and supplying first class plate rolling machines, DAVI understands that every customer need is different. DAVI R&D Department will process your requirements and help you selecting the optimum technical and commercial solution to maximize as much as possible the return on your investment. However, what would happen if your production schedule requirements had to change in the future? DAVI MCA machines and control systems are designed to allow easy retrofitting of accessories. May the need arise for greater plate handling capability, higher feeding capacity, improved process automation or, even, the ability to fabricate special parts within machine capacity needing special tools, DAVI R&D and Service & After Sales (SAS) departments will help you selecting the most appropriate retrofitting strategy and auxiliary equipment to suit it (such as overhead and side supports, gantry loaders, etc.).

Special Solutions for your Needs thanks to the Highest Level of Customization on the Market
Because of differences in output volume, required accuracy, processed materials, etc. each industrial sector demands for specific fabrication strategies. When it comes to rolling, accommodating such strategies requires expanding the stand-alone machine capability using specifically designed and fully customized accessories. Among many others, the following upgrades can be selected when needed: accurate plate handling devices, such as side and overhead supports; enhanced plate feeding systems, such as conveyors and gantry loaders; conical rolls and special conical packages, allowing for the manufacturing of extreme tapered sheets; interchangeable top roll with fast changing device, allowing for the manufacturing of very small diameters cans and cones, slightly derating the machine capacity to compensate deflections.

Highest Automation with Rolling Lines powered by state-of-the-art Control System
The so-called “fourth industrial revolution” or, more commonly, Industry 4.0 is changing the way fabricators perceive their workshops. DAVI MCA machines are equipped with 4.0 ready state-of-the-art control systems, specifically designed by DAVI R&D Department to help you getting the most out of your 4-roll plate rolling machine. DAVI CNC system, tailored for the highest possible level of automation on the Market, features, among others, the possibility of automatically generating a fully functional CNC program: importing the workpiece CAD file; recalling workpiece data from local network database through a barcode reader-based system; making use of offline capacity and spring back performance test. Thanks to DAVI CNC system, all operators, even the most inexperienced ones, will finally have the ability to match the required tolerances with maximum repeatability: a real boost to competitiveness.

Easy Installation with our on site or remote Assistance always available
Installing a machine has never been easier! In fact, thanks to the very compact pit-free design, your own team will be able to install the machine on the workshop floor right after delivery completion, without relying on external contractors. May the need arise for assistance, your team will be able to connect to DAVI “Remote” Engineering Team, specifically trained to provide outstanding and seamless support without the need of being physically on site. Obviously, in case of more complex automated lines, DAVI “On Site” Engineering Team will provide shift and timely mechanical, hydraulic, electrical & control installation followed by accurate machine and accessories commissioning for production. Depending on the machine complexity and your preference, operators training can be provided both remotely and on site.
