Guyson Multiblast ® RSB
new universal blast automation
Renown fi nishing and
shot peening equipment
manufacturing experts
Guyson International, have
created a new universal
automated blast system,
based on its existing
Multiblast® RSB, that now
incorporates roof mounted
servo drives to provide
saturation coverage from the
attached blast guns, across
the entire rotating table;
allowing full blast coverage
to multiple components
positioned on the table.
This new universal automated blast system
will prove ideal for subcontractors or
manufacturers with a varied component
mix of geometric sizes and shapes with a
requirement for a value adding cosmetic
finish, shot peening, general deburring,
paint removal, aerospace MRO cleaning
or surface finishing.
With a standard blast chamber dimension
of 1500 mm (wide) x 1500 mm (deep) x 900
mm (high), the cabinet is fitted with a large
front opening door allowing easy parts
loading access to a one metre wide,
painted steel, turntable (polyurethane
version available).
As standard, the Multiblast RSB comes with
two Guyson model 900 guns, each with its
own individual pressure regulator, allowing
optimum blast coverage of components
on the table. This number can be increased
to a maximum of eight guns if the blast
application necessitates. A blast nozzle
holding clamp option enables the guns
to be swapped out for cleaning whilst
retaining gun position, stand-off, angle etc.
Automated post blasting air wash is also
provided, as standard, to remove any blast
media residues and leave the parts clean
for any subsequent process.
For optimum component blast coverage,
the machine can be provided with either
horizontal or vertical servo driven gun drives.
Both provide 500 mm of precise traversing
travel, either across the turntable for full
saturation coverage or vertically stroking
(up and down) taller components to provide
uniform coverage, whilst the part rotates
on the turntable. Component shape and
dimensions dictates were the individual guns
are set for the correct angle and stand-off
distance to achieve overall coverage of the
target surfaces and these can be easily
set via a full width, right hand side door,
which is fitted for gun set up, adjustment
and maintenance.
A complete Guyson RSB automated blast
machine installation includes an efficient
Guyson model C800 twin cartridge dust
collector designed to draw off and collect
the dust laden air from the blast cabinet.
The heavier extracted particles are deflected
downwards towards the collection bin,

the lighter particles are captured on
the surface of the filters. A magnehelic
differential pressure gauge is supplied to
monitor the filter cartridge and indicate
when the cartridge requires replacing.
For applications where the dust represents
a health hazard Guyson offer a HEPA grade
14 secondary filter. Typical dusts with health
risks are nickel present in Inconel turbine
blades and cobalt chrome present in old
design orthopaedic implants.
All Guyson Multiblast machines are
provided with a human machine interface
(HMI) that simplifies operation of the
automated blasting, streamlines access to
control functions, and enables password-
protected direct entry of dimensional data
or processing parameters into the system’s
programmable logic controller (PLC).
The panel can also display control settings,
production data and system feedback
such as sensor and fault indications or
maintenance prompts.
This new universal Multiblast RSB blast
system allows virtually unlimited scope for
custom specification. The system is offered
in either suction or pressure feed options,
with either a turntable or single spindle for
components. Various Cyclone reclamators
options are available, all of which provide
substantial blast media savings, improve
cabinet visibility, and help with a more
consistent quality finish. These can be
also coupled with enhanced blast media
sieving and uprated dust collectors if the
application warrants.
Prospective user of Guyson automated blast
systems are encouraged to submit sample
components for free feasibility testing to the
company’s extensive development workshop
located in Skipton, England.
