MQL (Miniumum Quantity Lubrication)
In order to combine the
advantages which minimum
quantity lubrication can offer
in a production system, all the
components which make up
this system need to be examined
and aligned with each
other in the best possible way.

Advantages and disadvantages of minimum quantity lubrication
Advantages:
No need to dispose of coolant
No maintenance for coolant and
machine
No thermal shock to the tool
Disadvantages:
Increased thermal and mechanical
stresses on the tool
Connections need to be optimised
When using minimal quantity lubrication
it is extremely important to allocate the
supply points in the best possible way.
This is achieved by using, amongst other
things, a special design for the end of the
shank on the tools. The best results in
numerous trials were achieved using the
design shown below.
