Description ÖSTLING Markiersysteme GmbH
With the hand-held unit, the marking head is put on the workpiece manually
with a handle or a double handle. At the handle there is a releasing pushbutton
for the start of the marking.
The built-in unit corresponds to the table device without stand. It is intended for
the installation into production and assembly lines.
The combination unit is a combination of table unit and hand-held unit.
Depending upon intended purpose, the marking head can be fastened to the
stand or be removed and used as hand-held unit, e. g. for the marking of larger
workpieces.
Marking heads
The different marking heads differ in the size of the marking field: from
30 x 50 mm up to 80 x 140 mm.
All marking head compatible with the UMC box are equipped with a toothed belt
drive. All marking heads have 2 linear axes.
The marking speed of 1 - 100 mm/s is entered via the software. The marking
speed has a substantial influence on the quality of the marking result: the lower
the marking speed, the more evenly the marking.
During high marking speed the quality of the marking result does not only
diminish, but also step error arises by the mass inertia of the marking head. The
maximum marking speed depends therefore on the assigned marking head and
its maintenance. Bad maintenance decreases the maximum marking speed (for
maintenance see chapter 5).
Marking speeds over 80 mm/s produce nearly always insufficient marking
results. In addition it can occur in very rare cases that the resonant frequency of
the stepping motors is reached. In the case of resonance a strong decrease of
torsional moment takes place. In this case a slightly (1 - 2 mm/s) higher or lower
marking speed must be selected.
Marking speeds that are inherently dangerous to the marking head or other
parts of the marking systems will generate an error.
