Marking Characteristics
The BenchMark 320 can accommodate character
sizes from .762 to 100 mm (.030 to 4.0 inches) in
.025 mm (.001-inch) increments. Characters can be
rotated in 1° increments with printing resolutions
from 4 dots/cm (10 dots/inch) to 32 dots/cm
(80 dots/inch) for an engraved look.
Marking Speeds
The system generally marks three characters per
second using 5 x 7 font, 3 mm (.118-inch) high, 2
mm (.080-inch) wide characters. Speeds vary
slightly depending on the selected character size,
style, and dot density. Specific times can be verified
by a Telesis representative.
Marking Noise
Although every attempt is made to reduce noise,
the material being marked significantly influences
the noise level. For example, marking a solid lead
block produces less noise than marking a thin-
walled steel pipe.
Marking Depth
The BenchMark 320 can obtain a marking depth of
.127 mm (.005 inch) in mild steel (Rb53) using a
25XLE carbide pin with a 45° cone angle. The depth
of mark can be adjusted over a significant range by
changing the impact force (via software parameter)
or by changing the impact distance (pin stroke).
Specific depths can be verified by a Telesis
representative.
Pin Life
Pin life depends largely on the type of material
being marked, how hard or abrasive it is, and the
required marking depth. On typical metals with a
hardness of Rockwell Rb47, marking at a depth of
.127 mm (.005 inch), carbide pins average
approximately 9 million impressions before needing
sharpened.
