Choosing between sandblasting or grinding depends on the desired end result and the material's properties. Sandblasting is ideal for removing harsh surface contaminants and creating a roughened surface for coatings or paints. Conversely, grinding is suitable for refining the surface finish, removing burrs, or sharpening edges.
