For the processing of some materials such as aluminum, it is necessary to lubricate or cool during
the milling process. Various systems are available for this purpose.
Compressed air is required for all systems!

This system is a low-pressure system with coaxial spray nozzle for mist-free coolant application.
With this system, the coolant tank is under a pressure between 0.3 and 1.5 bar via a pressure control
valve, depending on the viscosity of the coolant. This ensures that after switching on the
compressed air supply, the lubricant and the blowing air are separated from each other at different
pressures to the nozzle outlet and the finest coolant droplets are pressed into the air flow at the
nozzle tip. The volume of the air flow at the nozzle tip and thus also the pressure is adjusted by an
adjustable needle valve on the nozzle unit. The supply of the cooling medium is also adjusted with a
needle valve on the nozzle unit. With the correct setting, the system works fog-free.

The pressure on the container must not exceed 2.0 bar. If necessary, adjust up or down via the
adjusting screw of the pressure display.
The lubrication system can be switched on and off separately via the green main switch.
