Turbine Blade Mold Polisher
An Auto-Polishing Robot device for Turbine Blade molds.
This project involved designing a wind turbine mold polisher to speed up the process of polishing turbine blade molds. Our team developed a system that uses a moving gantry, a yoke assembly, and a series of spring-connected polishing plates powered by pneumatic motors. I helped design the mechanical layout and motion system, making sure the device could adapt to the curved mold geometry while staying efficient and easy to operate. The project combined skills in CAD design, mechanical systems, and pneumatic actuation to build a solution that performs a repetitive process automatically and consistently.
The client’s current process of polishing turbine molds by hand was slow, inconsistent, and physically demanding. The challenge was to design a device that could polish the mold surface automatically, handle a large 9-meter cross-section, and maintain constant contact pressure across a complex surface while staying reliable and easy to maintain.
We designed a pneumatic-driven gantry that travels along the mold, pulling a network of interconnected polishing plates that move and conform to the mold’s shape through spring and ball-and-socket joints. Each plate uses air-driven polishing heads for consistent surface finishing. The system reduced manual effort and significantly increased efficiency while showing how automation and mechanical design can simplify industrial processes.
