The Best Polishing Solutions for Your Turbine Blades from Pengyu

The manufacturing technology applied to turbo-machinery components is a challenge in the aerospace sector. These components are often composed of high-strength superalloys; in order to withstand extreme operating conditions, they must be supported throughout their service life. Turbine blades in aircraft engines have complex geometries that require roughing and finishing by milling and grinding processes, respectively.

The finishing step of the convolute wheel is the last process in the processing of aircraft turbine blades. It is required to achieve a 0.4 μm above surface roughness without changing the shape of the workpiece. Compared with traditional unitized wheels, the convolute wheel shows higher efficiency and better effect in the surface treatment of various substrates, and can quickly remove burrs, oxides and coatings on the surface of the workpiece, providing a smooth surface treatment effect. They can complete grinding tasks in a shorter time and improve production efficiency. The surface of convolute wheels presents a three-dimensional structure similar to a honeycomb. This structure helps provide uniform finishing pressure and finishing effect, reducing scratches and thermal damage. When processing titanium alloys and high-temperature metals, the convolute wheel maintains excellent surface treatment effects without damaging the substrate. The convolute wheel also has high flexibility and adaptability and can adapt to irregular workpiece shapes and surfaces. The main finishing positions of turbine blades are the floor plan, elevation and R angle. Since the finishing methods of the three action points have different requirements, the convolute wheel is the best choice.
