during the cleaning cycle
in high-pressure (180 bar)
water jet units.
The component strip then
passes through the main
de-burring module, whose
brushes are mounted on a
quick-change unit to assist
rapid changeover to suit
different strip widths from
20mm to 110mm. Edge
chamfering and texturing of
the component surface can
be included in the deburring
cycle, and an integral measurement system
checks for brush wear and adjusts their
position to within ±0.15mm. Strip speed
through the SLE modules is adjustable, up
to 8m/min.
SLE manufactures additional equipment
for use both upstream and downstream
of the automated punching, cleaning and
deburring section of the press line. On
the input side, it offers pre-cleaning and
lubrication modules, including in-press
A new, modular range of equipment for
the degreasing, cleaning and deburring of
components as they emerge from a coil-
fed stamping press has been introduced
by Bruderer UK, under a sole agency
agreement with the German manufacturer,
SLE Electronic. The systems can be factory
fitted or retrofitted for operation with any
press line, not just the high-speed presses
manufactured by Bruderer in Switzerland.
Continuous cleaning and deburring is
essential for parts that are to be painted,
plated, bonded, welded or soldered, as
is often the case when manufacturing
electronic components. The SLE equipment
ensures flash and oil-free surfaces, with the
user being able to specify the degree of
cleanliness to suit the application.
Appropriate modules are combined from
SLE’s aqueous, chemical and mechanical
cleaning systems, which are positioned
on the output side of the press. Spraying,
rinsing and steaming units are available to
remove grease, oil and coolant, while scale,
flashes and some burrs can be removed
spray lubrication units, while output modules
include those for applying preservatives.
For cleaning discrete components, the
company also manufactures units tailored
to specific user requirements, complete
with component handling systems.
