Specialist in the development of
minimal quantity lubrications
(MQL) systems, Bielomatik, has
launched a new external mixing
nozzle for its two-channel system
capable of providing an increase in
the precise amount of oil introduced
into the system air stream and
subsequently delivered to the cutting
tip at rates up to 400-500mL/hour,
dependant on oil viscosity.

With the new external arrangement
oil is delivered to the mixing
nozzle from an in-line high speed
valve, exactly as internal systems.

Also, the oil is pressurised to 15 bar
and injected into the air stream,
ensuring that all air flow carries oil
to the cutting tip.

The technology will allow more
machining applications to benefit
from MQL technology – nozzle fed
coolant, rough milling, tapping,
shearing, punches, and so on.
