Wire cleaning for
plating quality
The new in-line Pressure Wet Cleaning
(PWC) system is developed to clean
drawn wire from lubricant residue to
obtain a smooth and glossy finish in
‘plating’ quality, at 6-14m/s (1,200-
2,800ft/min), dependent on wire size.
The system simultaneously performs
surface cleaning and polishing, in-line
with wire drawing machines and is used
for the most demanding wire cleaning
and polishing applications using
standard cleaning medium, including
cold water, water emulsions, oil, etc.
The wire leaves the cleaning unit
completely dry, ultra-clean, and with a
highly reflective appearance.
The PWC system is particularly
recommended for cleaning applications
in which a traditional process is
inappropriate, especially with wire
drawn in severe conditions resulting
in increased heat and burn lubricant
tightly bound to the wire surface
and embedded in micro-cracks and
longitudinal scratches.
Exceptional cleanliness is obtained with
a smooth and glossy finish in ‘plating’
quality which permits wire direct brass
coating, zinc coating, copper coating,
painting, etc, and wire cleaning prior to
heat treatment applications including
patenting, annealing, welding (mesh,
chain), cladding, etc.
In demanding applications, including
the production of highly reflective wire,
the PWC system revolutionises the wire
cleaning, enabling considerably higher
surface quality of the end product,
benefitting from the new Decalub wire
intermediate dry re-coating process,
allowing a smooth and ‘frictionless’
drawing with completely water soluble
sodium lubricants in all drafts, easy to
clean in-line at high speed with rust
preventive additives.
As a consequence, the PWC offers
significant downstream benefits and
savings with the potential to displace
acid, ultrasonic, etc.

ANNOUNCEMENT
Faster and more
accurate SLP probes
Laser Design, Inc, USA, a manufacturer of
3D laser scanning systems, has announced
that its next-generation line of 3D laser
scanning probes will be available from the
second quarter of 2007.
The company’s new and improved
Surveyor Laser Probes (SLP) are faster and
more accurate than their predecessors.
Included in the new line are the high
precision SLP-250, and the SLP-2000
which features a laser line more than
twice as long as competing probes.
Both of the new SLP models deliver
virtually noise-free scan data as a result of
breakthrough, proprietary advances in the
electronics and optics architecture.
The SLP-250, with a laser line length of
25mm, scans at ultra high speeds with
an accuracy of up to ±6µ and is primarily
used for small or highly detailed objects.
The lightweight SLP-2000, with a laser line
length of 200mm and accuracy of ±80µ,
is an efficient 3D laser scanning solution
for large parts.
The company indicated that the new SLP
models would be available with their fully
integrated DS-Series line of CMM-based
scanning systems.
In response to the needs of the
automotive, aerospace, automobile and
other industries, the new SLP probes were
also designed to be fully integrated with
the portable 7-axis arms from Faro, as
well as with the Renishaw PH10 indexing
system used on most traditional CMMs.
“These SLP probes can be used
interchangeably with portable CMMs,
traditional CMMs and Laser Design’s
own Surveyor DS-Series, DT-Series and
TS-Series 3D Laser Scanning Systems that
provide highly automated, programmable
scanning of parts or objects,” according
to company president Martin Schuster.
All of the new probes gather data with
higher densities than before, upping the
resolution by 50% to 750 points along the
laser line.
“The data from the new models is less
noisy, especially on reflective surfaces,”
said Mr Schuster. “With less noise, the
results are more accurate and less data
editing is required.”
Each of the probes has dual CMOS
receptors that capture up to 75,000 points
per second, making them suitable for
high-speed, non-contact 3D scanning. The
dual receptors inside the probe reduce the
number of scanning passes because they
capture more part geometry per pass than
low-tech single receptor laser probes.
SLP laser probes interface to PCs using
a standard USB connection, are easy to
install and can scan anything from small,
detailed parts to large automotive and
aerospace parts.
The probes are also integrated with Laser
Design’s Surveyor Scan Control software
for ease of use and compatibility with
numerous positioning systems. Additional
SLP models using the new electronics and
optics architecture are under development
and will be introduced later this year.
