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.
