In terms of the size and lubrication, i.e., the lubricant is almost completely consumed distribution of lubricant droplets created, the SKF MQL system during machining. so treatment of the lubricant is not required. described here generates a very homogeneous aerosol with a The actual lubrication is performed at the friction point between droplet size of approx.
Additionally, the transport of the aerosol through rotating The systems differ primarily only in that the aerosol pressure spindles and tools is unproblematic for the MQL systems even in the VarioPlus is monitored by an electric pressure switch that at very high rotational speeds, since the effect of centrifugal detects the current pressure in the aerosol generator and force on the oil droplets is very low.

Principle of operation The compressed air (primary air) entering through the main air Fig. 7 valve is forwarded through the downstream pressure regulating valve into the aerosol generator, where it pressurizes the lubrication oil in the reservoir. The lubricating oil, which has now been pressurized, flows through the variable area flow meter to the oil valve.

If the pressure difference falls The oil valve controls the quantity of lubricant flowing into the below a certain factory-set value, aerosol generation is aerosol generator, where it mixes with the constant inflow of resumed. This procedure is known as "cycling" and is audible primary air to form an aerosol mixture.
