The system has been specifically developed for large presses with a spraying width of up to 4,800 mm. When it comes to the lubrication of blanks and coils or the production of standard components, such as structural elements or even the outer skin parts of vehicle bodies, spray.xact 5000 is an optimum and economically efficient solution for all types of lubrication tasks.The heart of the system is the proprietary spray valve. It is electronically controlled and emits spray pulses at an exceptionally high frequency. That results in a particularly homogeneous spray pattern on the sheet metal surface. The oil quantity can be adjusted extremely precisely simply by changing the spraying parameters. In addition, the adjustment is completely reproducible due to the fact that it is 100 % electronically controlled.
Easy access to all of the components for maintenance or in the event of malfunctions as well as the redundant provision of key components for the emergency mode are, of course, ensured just like the easy operation of the system.

design and function
The spray unit consists of a rack, an upper and lower spraying chamber and an integrated control cabinet.
The entire spray unit can be moved into, and out of, the press system by way of the rack with its own drive system. In addition, the rack holds:
From there, the oil is supplied to the nozzle rails in the two spraying chambers.
supply and control system
The oil supply is characterised by a high level of flexibility: IBCs, drums or pipes that are connected to an on-site, central supply system can all be used.
In the example shown, the oil flows from a container into an intermediate tank from where it is then fed to the spray unit by way of a gear pump.
Additional key features of the oil supply modules are its filters, a collecting pan compliant with the German Federal Water Act (Wasserhaushaltsgesetz, WHG) and a signalling and control unit.
The spray.xact 5000 is controlled via its own control panel which can communicate with other, superordinate systems via a bus connection (Profibus, Profinet or Ethernet). Alternatively, it can also be connected to an external panel, e. g. in the control station, via a TeamViewer or Remote Desktop connection.
A small, separate service panel, which is connected to the control system via a cable, can be used flexibly in a mobile setting for maintenance or in the event of malfunctions.
