Bead blasting is a surface finishing technique that uses fine spherical beads, such as glass or ceramic, propelled at high pressure using compressed air. The process cleans, smooths, and prepares metal surfaces by removing contaminants like rust, oil, coatings, and oxidation while maintaining the original dimensions of the component. 

 

Unlike aggressive sandblasting, bead blasting creates a uniform, satin-like finish, making it ideal for precision parts, restoration work, and preparing surfaces for coatings or further finishing.
