東京ステンレス研磨興業 List of Products and Services

For stainless steel coil materials, continuous polishing and cleaning for the products will be performed. 【Quality】 ★ By performing continuous polishing on stainless steel coil materials, we can reduce polishing unevenness and maintain stable quality while enabling mass production. ★ We use a cleaning device linked to the polishing line to ensure high cleanliness compared to general sheet polished products. ★ We can handle thicknesses from 0.25mm to 3.0mm, which are difficult to manage with sheet polishing, allowing for high-quality polishing of thin to medium-thick plates. ★ Utilizing the strengths of buff polishing, we can offer various variations based on the required surface finish (reflectivity). 【Production】 ★ Since one-stop services for level cutting and slit cutting are possible after polishing, inventory management and delivery responses are smooth. ★ Even for glossy materials like "buff polished 'high gloss'," the characteristics of buff polishing allow for touch-up capabilities after welding processing, enabling rework and finishing polishing. ★ A portion of the stainless steel coil materials can be "polished," while the remainder can be "2B," allowing for partial polishing according to the required quantity. ★ We utilize our three locations to provide relay, inventory storage at each site, and delivery functions, enabling rapid and flexible responses.

<Conventional Challenges> ★ In manufacturing using pure titanium and hot-rolled materials, the removal of severe substrate (residual surface texture) and high-quality finishing are required. ★ Materials that meet cold-rolled standards are necessary, but the only available specification is pure titanium hot-rolled materials. At Tokyo Stainless Polishing Industry Co., Ltd., we address the challenges related to pure titanium and hot-rolled materials with our original polishing technology "EGR" for substrate polishing. <Tokyo's Solutions> ☆ We easily achieve grinding of approximately 100 microns (the grinding amount will be adjusted based on the surface condition of the base material), realizing surface roughness equivalent to cold-rolled materials regardless of the state of the material! (Ra0.21μm Ry1.0μm) ☆ We can accommodate materials with a maximum width of 2500mm and a maximum length of 7000mm, allowing for processing of various dimensions!! *For more details, please feel free to contact us.

<Conventional Issues> In conventional mirror polishing processes, specific chemicals containing nitric acid were used as abrasives, posing risks to both the work environment and the global environment. Our company has recognized this as an issue and has been advancing technology development. <Tokyo Steel's Solution> Tokyo Stainless Polishing Industry Co., Ltd. has achieved wet mirror polishing without the use of nitric acid, pursuing a balance between a better work environment and the global environment in line with ESG principles!! Of course, we maintain the same high polishing performance as before without using nitric acid, ensuring product quality. Our nitric acid-free wet mirror polishing process realizes consideration for society and the environment, which are essential elements of ESG management, and creates a sustainable future. ☆ Consideration for the environment! Eliminating the discharge of specific chemicals and reducing the burden on the global environment! ☆ Consideration for society! Our nitric acid-free polishing agents, which contain no nitric acid at all, create a labor environment that is safe and friendly to health! ☆ High governance! In addition to compliance with relevant laws and regulations, we possess standards that go a step further! *For more details, please feel free to contact us.

We would like to introduce Tokyo Stainless Polishing Industry Co., Ltd.'s original polishing technology, EGR (Electrolytic Grinding Reducing). EGR is an original polishing technology that combines grinding with abrasive wheels and neutral salt electrolytic polishing. [PR Points] ★ With EGR, hot-rolled materials are finished to a surface roughness equivalent to cold-rolled material 2B. Furthermore, the surface is polished even smoother than cold-rolled material 2B, significantly reducing pinholes. ★ By utilizing EGR as a base polishing method, the quality of subsequent diverse polishing finishes is greatly improved. We deliver surface quality suitable for materials used in food, sake storage, and medical tanks that require stringent surface quality. ★ EGR achieves scale removal and high-quality finishing for difficult-to-grind materials such as duplex steel, high-alloy steel, and titanium. * Please feel free to contact us for more details. * For information on polishing finish types, EGR, and finishing polishing technology, please refer to the PDF.

★When manufacturing with stainless steel, a cold-rolled finish is necessary, but only the standard for hot-rolled material No. 1 exists! ★I want to achieve a finish similar to cold-rolled material or mirror polishing for difficult-to-grind materials like hot-rolled material No. 1, high alloys, and titanium!! For those facing such concerns, Tokyo Stainless Polishing Co., Ltd. has solved and improved the situation using the following technologies! [PR Points] ☆With our original EGR polishing technology, we can finish rough thick plates and hot-rolled material No. 1 to a roughness equivalent to that of cold-rolled material finishes!! ☆We achieve the highest quality polishing finish even on steel materials with a thickness of 4mm or more, which have been considered difficult for mirror polishing!! ☆We provide high-quality polishing finishes not only for all types of stainless steel but also for difficult-to-grind materials like high alloys and titanium!! *For more details, please feel free to contact us. *Please refer to the PDF for information on polishing finish types, EGR, and finishing polishing technology.

★ The specifications of high alloys, titanium, and stainless steel hot-rolled materials sourced from overseas do not match the specifications of our products. ★ The specifications and dimensions of materials that cannot be processed by milling, but we want to reduce the plate thickness. ★ For steel materials that require precision processing, we do not need the same level of reduction as milling, but we want to adjust the plate thickness according to specifications. Alternatively, we want to adjust the plate thickness partially. For those facing such concerns, Tokyo Stainless Polishing Co., Ltd. has solved and improved the situation using the following technologies! ☆ Our original technology, EGR polishing, can accommodate a thickness reduction of 1.0mm (approximately 30 microns per pass). ☆ With pressure adjustment at the micron level, we achieve stable plate thickness deviations, and we can also perform partial thickness adjustments, finishing to the stringent plate thickness specifications required. ☆ We realize thickness polishing not only for all types of stainless steel but also for difficult-to-grind materials such as high alloys and titanium. We take pride in our achievements with materials for gas turbine engines, among others. We reduced the thickness of SUS No.1 (four-stage hot-rolled product) by approximately 1.0mm, compressing the plate thickness deviation to just 0.082mm, reproducing dimensional specifications that cannot be achieved with hot-rolled materials and achieving stable plate thickness deviations equivalent to cold-rolled materials. * For details, please refer to the achievements and downloadable catalog below.

★When titanium and titanium alloy materials are pressed and shaped, the wear of the molds becomes severe and frequent repairs are needed due to the carbides and oxides adhering to the material, resulting in high maintenance costs. ★We tried removing the carbides and oxides through polishing, but due to unevenness and variability in the polishing process, we cannot maintain a consistent quality in the processed products. For those facing such issues, Tokyo Stainless Polishing Co., Ltd. offers solutions through the following methods: ☆ Remove surface oxides and carbides from titanium coils and hoop materials using wet coil polishing! ☆ Continuous polishing with wet coil polishing allows us to maintain consistent surface quality along the entire length of the coil and hoop! ☆ By maintaining consistent surface quality, it is suitable for press processing with progressive and transfer molds! Of course, sheet materials can also be polished, so we can accommodate single-stroke molds as well! ☆ By removing foreign substances through polishing, we significantly extend the lifespan of expensive molds, leading to a reduction in total costs for our users! *For more details, please feel free to contact us. *Please refer to the catalog for information on wet coil polishing.
