Finishing Operations

Finishing operations are the processes that are applied to the workpiece at the end of a manufacturing process, and after completing all other relevant operations that bring the product to its required dimensions. Finishing operations involve polishing, reducing the surface roughness, eliminating wrinkling, and grinding to enhance the surface texture and provide a better surface finish to the workpiece surface.
