Surface finish after barrel polishing

Advanced inspection equipment and abundant processing facilities that support productivity and technological capabilities! Introduction to glossiness and surface color.

Barrel polishing is a very suitable polishing technique for rounding the edges of machine parts and metal components. It is evaluated based on three factors: surface roughness, glossiness, and surface color, with customer requests such as "finer," "shinier," and "whiter." While surface roughness and corner radius are indicated in the drawings, requests regarding glossiness and color are mostly expressed in abstract terms. The shape of the surface irregularities, or surface characteristics, varies depending on the processing conditions and polishing materials used in our company. Since we do not have color difference meters or gloss meters, the evaluation is based on visual inspection rather than numerical assessment. However, we strive to respond to requests as much as possible by clarifying differences in surface conditions using magnified images from a microscope. *For more details, please refer to the PDF document or feel free to contact us.*
