In the following
Clean3
sequence, the soiling cleaned off using
ultrasound from the fine holes, blind holes and gaps can be
removed due to its short-term (< 30 seconds) flow triggered by
a fast ( 2-3 Hz) oscillation movement with sufficient deflection
(dependent on the positioning around 3-5°).
Prerequisite of the flow using fast oscillation is in turn
appropriate parts positioning far enough on the outside in the
rotating cleaning basket for the holes and gaps to be flowed
through.
Depending on the result, it can be advisable after removal of
the soiling in
Clean3
to perform ultrasonic cleaning again using
40 or 80 kHz in Clean4.
With the procedure described above, the intended ultrasonic
cleaning duration in the standard cleaning program is divided
onto the above 2 or 3 ultrasound sequences and additional
cleaning time is only programmed for the additional fast
oscillation.

Rinsing parameters recommendations
in Expert Mode
One example problem solution using modifications of the
standard cleaning program shows which possibilities of the
Expert Mode are enabled for the probably most frequent rinsing
problem:
The parts still have residues of the cleaning medium in fine
holes, blind holes and gaps in the range of internal diameters of
less than 1/10 mm that in the case of unfavourable positions
also reach the outside surfaces from there and become visible
there as stains or blemishes.
On the one hand, it is then advisable firstly to rinse with
ultrasound support (80 kHz) with slow rotation in the rinsing
steps
Rinse1 – Rinse3
.
The prerequisite for effective ultrasound-supported rinsing also
in the holes, blind holes and gaps is that the parts positioning in
the rotating cleaning basket enables
•
the displacement of the, also in vacuum, still remaining
residual air bubble there due to the penetrating rinsing
medium and
•
the spinning out or draining again of the rinsing medium
