Due to the curved surface characteristics of turbine blades, traditional mechanical or manual polishing is insufficient for precision control and uniformity control stability. Due to its use of non Newtonian fluid abrasives, it has good fluidity and can uniformly contact the polishing surface for grinding under pressure. And control the accuracy through pressure, time, and abrasive particle size. When polished turbine blades rub against air or liquid, the friction force is smaller, and the surface oxidation resistance of the blades is stronger, which can significantly improve their performance and service life.
