Surface finish after barrel polishing

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 "smoother," "shinier," and "whiter." While surface roughness and corner radius are specified in the drawings, requests regarding glossiness and color are mostly expressed in abstract terms. The surface texture, or the shape of the surface irregularities, 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 values. However, we strive to respond to customer requests as much as possible by clarifying the 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.*

Removal of black discoloration layer [barrel polishing]

Removal of black discoloration layer [barrel polishing]

Solving problems through oil removal (degreasing) and optimization of processing conditions! Introduction of a case study on barrel polishing.

This is an introduction to a case where the removal of a black discoloration layer was performed. We received an inquiry from another barrel polishing company stating, "We had barrel polishing done, and while the burrs were removed, the surface of the item was discolored black compared to before the polishing. We cannot deliver it to the customer in this condition, so is there any way to restore the material's color?" We performed barrel polishing at our company to remove the black discoloration layer and returned it to the original material color. Depending on the type and amount of oil on the raw material before barrel polishing, as well as the polishing conditions, dirt can sometimes adhere to the surface. This issue can be resolved by oil removal (degreasing) and optimizing processing conditions. *For more details, please refer to the PDF document or feel free to contact us.
