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.

Barrel Polishing Customer Case Study

Barrel Polishing Customer Case Study

In addition to being able to evaluate objectively, we consistently carry out processing with uniform high quality through a "strict processing procedure manual."

We would like to introduce a case of barrel polishing conducted by Nishimura Giken Co., Ltd. The gas stove component that supports the heating container, known as "gotoku." The customer's specifications regarding the safety of the edges and sharp parts of the gotoku were abstract, stating that "housewives should be able to touch it with wet hands without getting cut." In response to this challenge, our company used projectors and microscopes to numerically present the rounding dimensions (R dimensions) of the edges and sharp parts processed by polishing. In addition to being able to evaluate objectively, we consistently perform high-quality processing with strict processing procedures to ensure uniformity. Of course, we received high praise from our customers. On our website, we also showcase cases of barrel polishing for "stainless steel vintage trays for bakeries" and "sprockets for motorcycle racing." *For more details, please refer to the PDF materials or feel free to contact us.

Barrel polishing process - glossy finish

Barrel polishing process - glossy finish

The areas with a glossy finish also achieve surface reinforcement, resulting in a product that is resistant to wear.

Like a mirror finish, it is polished until a gloss appears on the surface. The surface is gradually smoothed out until it reflects light. For design products, this improves appearance, and for functional products, it enhances sliding properties (movement). *It is inferior in both smoothness and gloss compared to a mirror finish. For more details, please download the catalog or contact us.

Introduction to GUM polishing of Dai-Ei barrels.

Introduction to GUM polishing of Dai-Ei barrels.

Ideal for processing in areas where tools cannot reach! Capable of deburring and adding radii, among other tasks.

"GUM polishing" is a grinding process that uses a viscoelastic abrasive material (GUM) mixed with abrasive grains, which is flowed at low speed under high pressure to smooth products and remove cross burrs. It is possible to improve the surface roughness of inner surfaces, remove burrs, and create radii. By combining this process with barrel polishing, complex treatments can also be achieved. Please feel free to contact us when you need our services. 【Workpieces and Features】 ■ Suitable for processing in areas that tools cannot reach ■ Capable of improving the surface roughness of inner surfaces, removing burrs, and creating radii ■ Complex treatments are possible by combining with barrel polishing processes *For more details, please refer to the related links or feel free to contact us.

Holding technology "Barrel Polishing"

Holding technology "Barrel Polishing"

Even in places that are difficult to polish with machines, finishing is possible! Compatible with materials like aluminum.

"Barrel polishing" is a processing method that involves placing workpieces along with granular polishing materials (media), compounds, and water into a barrel, which is then rotated and moved up and down to perform polishing. Since the media inside the barrel is small and can move freely, finishing is possible even in areas that are difficult to polish with machines. Shizutech has 8 vibration barrels suitable for batch processing of mass-produced parts, 11 rotary barrels, and 4 centrifugal barrels suitable for processing single pieces of small-lot production parts. 【Method Characteristics】 - A type of abrasive processing method - The workpieces are placed in the polishing tank along with media and compounds - This method processes the workpieces based on the relative speed generated between the media and the workpieces when rotational motion is applied to the polishing tank - Generally suitable for batch processing of small parts *For more details, please refer to the PDF document or feel free to contact us.
