TMP4500E MARKING HEAD (CONTINUED)
Marking Characteristics
The TMP4500E can produce character sizes from 1.5 to 25 mm
(.060 to 1.0 in.) increments. Characters can be rotated 359° in 1°
increments with a printing resolution range from 4 dots/cm
(10 dots/in.) to 31 dots/cm (80 dots/in.) for an engraved look.
The depth of mark can be adjusted over a significant range by
adjusting the pin stroke and/or adjusting the Depth parameter in
the marking system software.
Marking Speeds
The system can mark 3.175 mm (.125 in.) high characters in the
5x7 font at a rate of 2 characters per second at a depth of .45 mm
(.018 in.) in mild steel. Speeds will vary widely depending on the
selected character size, style, and dot density. Specific times can
be verified by a Telesis representative.
Marking Noise
Sound pressure-level tests were conducted on the TMP4500E
Marking System using a Larson-Davis Model 710 sound
pressure meter while dry firing the marker at a 50% duty cycle.
The maximum sound pressure level during the test cycle was
measured at 81.4 dB. The time-weighted average (LEQ) using
the 3 db rule without threshold was 73.1 dB. Typical
applications average a 20% to 30% duty cycle where the time-
weighted average would not exceed 69.1 dB(A).
The sound pressure-level tests were carried out under controlled
conditions, imitating as closely as possible, predicted normal
operation. However, noise level is heavily dependent on the part
being impacted. Conditions such as the material being marked,
the rigidity of the work piece, machine settings, ambient noise,
etc., may all vary when in operational use. Such variables will
alter the actual noise level.
Despite detailed guidance provided with each machine, variable
operating conditions are beyond the control of Telesis. The
responsibility of establishing safe working levels of use remains
with the end user. Accordingly, you should conduct your own
sound pressure-level tests for your application while marking
actual work pieces.
Pin Life
Pin life depends largely on the type of material being marked,
how hard or abrasive it is, and the required marking depth.
Vibration Data
Total hand-arm vibration does not exceed 2.5 m/s
2
.
Vibration tests were performed under controlled conditions
imitating, as closely as possible, typical normal operation.
Conditions such as rigidity of the work piece, material, setting
of the machine, etc. may vary in actual operational use and
would alter the actual vibration level. Despite detailed guidance
instructions provided with each machine, such conditions are
beyond the control of Telesis and must remain the responsibility
of the end user. Accordingly, you should conduct your own tests
to establish safe working levels of use.
The vibration tests were conducted using the following
parameters:
Pin Stroke ................................. 8 mm (.31 in) set for Long Throw
Marking Base ........................... 20 mm (.79 in) thick steel
Marking Surfaces ..................... 3 mm (.125 in) thick steel plate
Marking Mode .......................... Dot
Text Marked ............................. QWERTYUI12345678
5x7 font, 3mm (.12 in) characters
