Principle

Pump working principle
The power source of the MQL system: It uses a pneumatic positive displacement pump to achieve oil delivery and metering.
Metering method: The atomizing pump controls the air flow through the air metering screw, and works together with the stroke adjustment knob to achieve accurate proportioning and output of the oil and air mixture.
Atomization principle
In the atomizing pump of the MQL system, the oil and air are kept separate in the pump until they reach the application point. Through the coaxial output method, the fluid and air are combined at the tip of the nozzle, and the “air jacket” around the fluid outlet uniformly atomizes the fluid
Pulse generator principle
The pulse generator of the MQL system controls the cycle rate of the pump by controlling the on-off rhythm of the compressed air. If precise control is required, use the adjustable air switch and adjust the knob to set the frequency.

Adjustment

The nozzle position is crucial for micro lubrication effect, and should be placed in the optimal position according to different processing methods (such as end face milling, peripheral milling, etc.), ensuring that the nozzle coupling block is horizontal or pointing downwards.
In the process of use, if the Oil mist lubrication effect is not good or the nozzle position changes, it needs to be adjusted in time, which helps to maintain the good lubrication performance of the system and is also a part of the maintenance work.
Minimal quantity lubrication’s different types of nozzles (flexible plastic, semi-rigid copper, stainless steel, etc.) have their own characteristics, and attention should be paid to avoiding damage during use. For example, flexible plastic nozzles are prone to being touched and displaced, semi-rigid copper nozzles can be work hardened by repeated bending, and stainless steel nozzles have good rigidity but are not easily bent or deformed.
