Guyson Robot Loaded Shot Peening Automation With Traceability

Guyson International has designed, manufactured and installed, into an international manufacturing company, a robot loaded, automated shot peening system.
SKIPTON, U.K. - March 19, 2020 - PRLog -- Guyson International, the UK's foremost industrial finishing equipment manufacturer, has designed, manufactured and installed into an international manufacturing company, a large automated, robot loaded, dual media shot peening system for fatigue life enhancement, typically required in aerospace and medical applications.

The system comprises two Guyson Multiblast RXS900 automated blast systems; one for steel shot peening and one for glass bead peening, with robotic work piece transfer between the two blast systems. The computer controlled process was designed to meet AMS2432 standards demanded by the client.  This fully integrated process with traceable record keeping delivered increased capacity with less labour compared to the existing process.

Batches of 12 workpieces in a dual indexing carousel for In/Out control are picked up one at a time by an ABB robot and sequenced through the system.  Suitable for turbomachinery turbine blades or medical implants, each piece is loaded into the six rotary indexing stations of the Guyson RXS900 (Rotating indeXing Spindle) shot peening system located to its left. The components index clockwise through two shot peening stations - both equipped with two boron carbide blast nozzles, four in total, which vertically stroke up and down the workpiece, delivering the correct Almen intensity, at the correct impingement angle and providing 100% surface coverage.

Steel shot blast media is delivered to the blast nozzles via a 300 litre twin chamber pressure pot, allowing for continuous media flow during the long peening operation.  To meet AMS2432 standards media flow rate is monitored and controlled with Magnavalves whilst closed loop peening air pressure, spindle RPM and vertical gun traverse rates are all held within tight specifications. An airwash station, separated by an internal pneumatic vertical door, removes residual dust and blast media from the components prior to removal from the blast machine.

Following steel shot peening a de-contamination glass bead peening operation is undertaken. The same ABB robot unloads each station as it exits and transfers components to the glass bead peening system; where bead peening takes place in a similar blast system, but using glass bead. Once both systems are fully loaded, a continuous production run of one part in and one part out follows.

Prospective user of Guyson automated blast systems are encouraged to submit sample components for free feasibility testing to the company's development test centre located in Skipton, England.  To arrange free blast trials on your components, prove the process and make recommendations on the most suitable blast system for you +44 (0)1756 799911 or email,
