Function description
Principle of minimum quantity lubrication (MQL)
The minimum quantity lubrication is a loss or consumption lubrication, this means, the
lubricant used is almost completely consumed during processing, so that preparation in the
circuit is no longer necessary. The actual lubrication task at the point of action between the
tool and the workpiece is achieved by means of oil droplet, the aerosol, which is finely
dispersed in an air stream. With the minimum quantity lubrication, an effective lubrication of
cutting processes can be achieved using the smallest amounts of lubricant. The elaborate
cleaning and disposal of large quantities of lubricating and cooling lubricants are thus
eliminated or minimized.
Aerosol generation
The minimum quantity lubrication system DYNACUT-MDM described here produces a very
homogeneous aerosol, based on the size and the distribution of the oil droplets, since the
lubricant is atomized in a controlled manner. The functional principle of the spray nozzles
makes it possible to produce aerosols with a droplet size of approx. 15 - 35 μm.
Layout and function
The DYNACUT-MDM minimum quantity lubrication system consists of a lubricant reservoir,
one or several mixture regulating units and one or several lubricant lines with spray nozzle.
The lubricant reservoir is pressurized via a compressed air connection and hand valve. The
solenoid valves for air and coolant are opened by switching the main switch, whereby the
compressed air as well as the lubricant are transported to the spray nozzle via separate hoses.
The required quantity of lubricant and atomizer air is regulated via the throttle valves
mounted on the mixture regulating unit. The internal pressure of the lubricant reservoir is
adjusted via the control valve mounted on the lubricant reservoir.
At the end of the lubricant line is a spray nozzle, with the help of which the aerosol is
generated. The lubricant is then transported directly to the lubrication point using the carrier
air.
