Case studies for solutions to concerns about surface finishing and roughness of stainless steel and thick plate steel materials.
EGR
We'll finish hot-rolled material No. 1 as cold-rolled material 2B!?
★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.

basic information
【EGR (Electrolytic Grinding Reducing)】 〇 The high-temperature oxidation scale on materials after hot rolling and annealing can be descaled with low environmental impact without using acids. 〇 Regardless of whether the surface has high-temperature oxidation scale or is pickled, a reduction of about 30μm per pass of the head can be achieved. EGR grinding is applicable to all stainless steel grades and can also achieve polishing effects on high-alloy and pure titanium, among others. *For more details, please feel free to contact us.
