ROBOTIC BLASTING - NEW GUYSON FACILITIES
New technique aids process evaluation and
demonstrates efficiency benefits
Leading European finishing equipment manufacturer Guyson
International has installed several new advanced
robotic capabilities into its Skipton demonstration and engineering
centre CAD/CAM design facility to assist its customers with
their process evaluation and precision blast simulation. With
this fully integrated working robotic cell adjacent to the
manufacturing area of the factory, Guyson is able to demonstrate
advanced blast nozzle manipulation techniques and the cost
saving and efficiency benefits its automated blast customers
Fast program development
With the introduction of new industry proven CAD/CAM software
technology, Guysons engineers are now able to take a
CAD STP (Step) file of the proposed customer component that
requires precision blast finishing or peening and produce
accurate 3D simulations of the blast treatment on the component,
showing actual blast cone coverage of all critical areas.
The programming software allows off-line programs to be developed
in hours compared to days when using teach pendant programming
tools which previously could delay production. The software
also allows the optimum impact angles and stand off distances
to be guaranteed which was impossible with teach pendant techniques.
The new Guyson technique speedily removes any customer concerns
regarding achievement of part coverage by verifying the process
before the machine is even built. Subsequent parts can be
proved in the same way and added to the portfolio and menu
selection, allowing rapid component switching and lower parts
Cost saving and efficiency benefits
Adoption of these sophisticated new precision robot blaster
techniques from Guyson will also deliver very real investment
cost savings with the potential total purchase price of a
fully automated robotic precision blast system coming under
£75K. These cost savings, compared to many alternative
systems, are coupled with real daily running cost savings
in compressed air consumption. This is achieved by using far
fewer blast guns but these being dedicated to deliver the
precision blast coverage required, rather than adoption of
a blanket coverage approach with more guns needed to ensure
sufficient media will hit the target. The Guyson precision
blast approach also delivers lower media costs through lower
wastage and also less media breakdown and furthermore allows
a smaller and cheaper dust collector to be specified, also
with reduced waste disposal issues.

Robotic Blast System
Alongside all these process benefits Guysons precision
robot blast systems offer a greatly reduced overall footprint
to the machine cell, helping to realise six sigma processing
principles. Adoption of this type of precise robot blasting
can also eliminate completely operator Health & Safety
issues relating to both RSI and vibration white finger problems.
Richard Standing, Guysons Business Development Manager,
stated We would like to demonstrate to clients the full
benefits of moving their finishing production to the top of
the automation ladder with a fully automated precision
robotic blast system. Guyson sees this move as vital for medical
and aerospace customers to be able to deliver the required
consistency of finish from the blast process, whilst meeting
stringent quality standards. It will also assist other high
volume manufacturers to be better able to compete against
low cost labour economies.
"This latest demonstration facility, coupled with Guysons
free component trials service, enables customers to visit
just one company, prove that their intended robotic handling
system is going to synchronise with the chosen automated finishing
unit and minimise any concerns before they invest in the capital
Process validation aid
Guyson are recommending full adoption of
this type of precision robotic blasting for clients who manufacture
precision components with demanding surface engineering topography
requirements and/or any subsequent validation issues, typically
medical implants and aerospace turbine blades.
