Benefits of Metal Polishing

Aesthetics

Abrasive wheels are used to polish and smoothen the metal surface. This technique also helps in removing scratches, imperfections, and tarnishes.

Protective Layer

Polishing offers improved surface quality. Polished metal crafts perform and appear better compared to non-polished ones. This technique helps resist contamination and oxidation which eventually creates premature corrosion.

Reflective

A polished metal surface creates a shiny finish which results in an effective light reflection. This property is beneficial for architectural elements jewelry, and other decorative items.

Functionality

Metal polishing improves functionality in specific applications like machinery components. The polishing technique eliminates surface imperfections giving a smooth and even finish. This also reduces friction which improves the overall performance.

Cleanliness

The metal polishing technique gives an appropriate finish that prevents the risk of germs and bacteria. The finish that this technique creates allows efficient cleaning time.

After knowing the advantages of metal polishing, we can now move on to the different finishes it offers.

This stage is used to remove traces of dirt, dust, or any impurities acquired during the previous process. Grating is used on jewelry pieces with a coating of gold or silver.

Grating

Roughing

Roughing is also called sanding. This stage involves removing of defects by using a course material to show a smooth surface that’s free of imperfection.

Roughing

Grinding

The grinding stage is essential in removing marks left by the roughing stage.

Polishing

The polishing stage removes the marks left by the grinding process. When polishing is finished, the metal craft is ready to be given the desired finish.

Polishing

Glossing

This stage is used to restore the shine of the metal surface and give it a uniform finish. Glossing is applied to parts that will not have any metallic coating.
