Hand polishing is a manual finishing process used to refine and enhance surfaces by removing imperfections, oxidation, or scratches. It involves applying apolishing compound with a cloth, pad, or brush and using controlled pressure to achieve the desired smoothness and shine. This technique is widely used onmetals , wood,plastics , and stones to restore luster, improve aesthetics, and prepare surfaces for further treatment. Hand polishing offers precision, allowing careful control over delicate or intricate parts. While it requires more time and effort than mechanical polishing, it ensures a high-quality finish, making it ideal for fine detailing and restoration work.
All metals like (Aluminum ,stainless steel etc.), and some plastics.
Achieves Ra ≤ 0.2 µm.

Tools typically include abrasive papers or pads, buffing wheels, and polishing compounds. The selection of tools depends on the material and desired finish.
Benefits include achieving a high-gloss finish, improving surface smoothness, enhancing corrosion resistance, and increasing the part's overall aesthetic appeal.
Hand polishing can significantly reduce surface roughness by removing microscopic peaks and valleys, resulting in a smoother and more reflective surface.
