Grinding and sanding machining are precision finishing processes used to smooth, shape, and polish materials to achieve the desired surface finish and dimensional accuracy.
Grinding is a precision machining process that involves the removal of material from a workpiece using abrasive wheels or belts. It is employed to achieve high accuracy and fine surface finishes. Grinding is typically used for finishing operations after other machining processes such as milling or turning.
Sanding is a surface finishing process that uses abrasive materials to smooth and polish surfaces. Unlike grinding, which is used for shaping and finishing, sanding is primarily used for surface preparation and finishing.
