Practical suggestions
5.19 Practical suggestions on adjusting the parameters
The microdot Marking Unit provides high flexibility in order to match the various marking needs
by means the adjustment of different parameters:
• Stylus stroke frequency (from 10 to 100 Hz)
• Stylus stroke pulse length (from 2.5 to 9.5 ms)
• Stylus movement speed (from 1 to 200 mm/sec)
• Air pressure (max 6 Bar)
• Type of the stylus
• Stylus-to-plate distance.
Depending the various combinations of these factors, very different marking results may be
obtained.
In any case a compromise between marking
speed and quality must be reached as both act in
antithesis.
We remember that, over some limits, the marking
deep and the speed are in antithesis too.
Therefore, when you have a piece to be marked the first question is:
Which factor to privilege; working speed, marking quality, marking deep, or
the noise level?
1. If Speed is prevailing, we suggest:
Frequency 100 Hz, Pulse length 5 ms, Speed from 10 to 50 mm/sec in relation to the
quality result you need (more is the speed more are the dot distance, and worse is the
quality), movement speed with stylus up: 100mm/s.
2. If Quality is prevailing, we suggest:
Frequency 100 Hz, Pulse length 5 ms, Speed from 10 to 50 mm/sec in relation to the
character high (smaller the character and less must be the speed).
3. If Deep is prevailing, we suggest:
Frequency 50 Hz, Pulse length 9.5 ms, Speed 10 mm/sec using the heavy sintered stylus
(option). Remember that this stylus can not be used for soft material, as plastic or
aluminum.
4. If low noise is prevailing, we suggest:
Frequency from 10 to 25 Hz, Pulse length 9.5 ms, Speed value according the previous
criteria (in this case the dots are spaced and the result seems as a dot matrix).
Besides, we remember the following general rules:
• The heavy sintered stylus 92 HRC is used for hard material and/or deeper marking. In
other cases the lighter stylus can be used.
• More the distance between the stylus tip and the marking surface and more is the stroke
power (adjust the distance between 0 and 5 mm max.).
• In case of pressure leakage in consequence of the distance between marking unit and
compressor, or when you have to mark very soft material (plastic, aluminum, etc.) at high
marking speed (>20 mm/sec), we suggest to reduce lightly the Pulse length of 0.5 - 1 ms.
