Aircraft impeller parts have complex shapes and structures. The blades of the impeller are usually curved. The optimized curved shape can effectively guide the airflow and maximize the propulsion efficiency. The root of the blade is connected to the shaft to form a tight rotating unit. The blade end is usually slender to reduce air resistance.
Moreover, the machining precision of the impeller is very high, and the surface finish requirements of the blades are very strict. The dimensional tolerance and shape tolerance of the impeller must be strictly controlled to ensure the balance and stability at high speeds.
Ordinary polishing methods cannot solve the impeller’s tiny burr removal and finish requirements, while fluid jet polishing technology solves this problem. Fluid polishing is a high-precision polishing method that is very suitable for parts with complex shapes and high precision requirements.
Working Principle
Fluid polishing is done by placing the impeller in a mold containing fine abrasives, usually silicon carbide, boron carbide or diamond fluid abrasives. When the abrasive particles flow, they contact and rub the impeller surface evenly under the action of high-speed flow, thereby removing oxides, scratches, tiny defects, etc. on the surface, and achieving fine polishing of complex shapes and difficult-to-reach areas.
Advantages:
Quick processing of complex shapes: Fluid polishing can complete the polishing requirements of special shapes, curved surfaces, inner holes, concave and convex positions, and difficult-to-reach angles in a short time.
High precision: By adjusting factors such as flow rate and abrasive size, the surface finish can be accurately controlled to meet the strict requirements of aircraft engines for impellers.
Uniform polishing: The fluid can flow evenly on the entire surface of the part, so the polishing effect is very uniform, which is easy to achieve fine finish requirements.
Scope of application:
Fluid polishing is widely used in aviation parts that require high finish, such as aircraft impellers, turbine blades, precision parts in engines, etc. These parts usually require smooth and flawless surfaces to ensure stability and durability under high-speed rotation and high-temperature environments.
Summary:
For precision parts such as aircraft impellers that require extremely high finish and surface quality, fluid polishing provides a very effective solution. By optimizing the flow of fluids and the selection of abrasives, the impeller surface can be smoothed on a microscopic scale to meet the strict surface finish standards of the aviation industry.
