Guyson offer both manual and automated machine options for grit blasting and shot peening turbine blades. Grit blasting is the perfect solution for removal of oxide layers and coatings from a selection of turbine blades and nozzle guide vanes (NGV) either during original manufacture, or in a maintenance, repair and overhaul (MRO) situation. Whereas shot peening is regularly specified for aerospace and land based turbine blades to enhance component service life.
Manual Grit Blasting of Turbine Blades
Euroblast PF (Pressure Fed) systems are the machines to choose - the blast stream is generated by a Guyson G27 or G55 Pressure Pot and the blast media is fed from the pressure vessel into the cabinet through heavy duty hose to the blast nozzle. Pressure fed blast systems can be up-to four times faster at blasting than suction fed, so great for industrial applications where time is money and a fast turnaround of components is required.
Automated Grit Blasting of Turbine Blades
Guyson offer two main options, either straight forward automated blasting where multiple blast nozzles saturation grit blast the part which is placed on a spindle or table and slowly rotated whilst the blast nozzles stroke vertically up and down the product - perfect for certain parts and volumes.
Or alternatively the more precise robotically controlled grit blasting, where a single nozzle is fastened to the end of a robot arm and precisely directed around the turbine blade (or the robot arm can hold the part and manipulate it precisely around a fixed nozzle). Either of these two later options can offer substantial customer benefits over the multiple nozzle scenario - please read our ‘10 Reasons for Robot Blasting’ brochure or visit our Robotic Blasting pages to learn more.
