Compressor
Winbro’s technology goes beyond the application of cooling holes and features to the compressor. Engine manufacturer’s require precision aerofoil shapes for compressor blades and vanes, made from materials such as stainless steel, super alloys and titanium, which are difficult to conventionally machine.
ECM Forming is the forming of aerofoil shapes using a ‘salt’ based electrolyte and extreme high power. Winbro’s process is capable of producing a finished airfoil – concave and convex surfaces, leading and trailing edges as well as the platform in a single operation. Winbro’s process can be used on components with finished root forms optimising the manufacturing processes.
Components are formed by a process of anodic dissolution, with the cathode profile effectively being shaped onto the component. No cathode wear occurs due to the ECM process. Typical ECM systems have a 20,000 amp capacity, and multi station tooling permitting up to three components to be processed simultaneously.
