Thank you very much for your exceptional support as always. We are pleased to announce that our latest water-soluble cutting oil, the "Daphne Alpha Cool NV Series," has received the "Minister of the Environment Award" at the Green Sustainable Chemistry (GSC) Awards. This award recognizes our contribution to "reducing environmental impact" and acknowledges our product as socially implemented. The NV Series includes two types: an emulsion type that supports a wide range of processing from non-ferrous to alloy steel, and a soluble type specialized for iron processing. By combining the concepts of "improving the work environment on-site" and "reducing the amount of concentrate used," we have developed a water-soluble cutting oil that is friendly to the environment, producers, and the economy, which has been adopted by many customers. To live up to the name of this award, we will contribute to both "improving the work environment and management costs" for those supporting manufacturing sites and the Japanese manufacturing industry through new product development and proposals. ◆ List of winners of the 24th GSC Award / From the JACI Public Interest Incorporated Association for the Promotion of New Chemical Technology HP ◆ https://www.jaci.or.jp/gscn/page_03/awards/gscaw-2024.html

Thank you very much for your continued patronage. We will be holding the 2024 Cutting Heat Treatment Research Meeting (ZOOM Online). 【Introduction to Seminar Content Part 1】 We are pleased to have Professor Emeritus Yamane from Hiroshima University Graduate School of Engineering as a speaker, who will give a lecture on the effects of cutting oils from the perspective of cutting conditions. It is known that the effects of cutting oils vary significantly depending on "cutting conditions," such as the work material, tools, the method of oil supply, and machine tools. In this lecture, we will consider the reasons behind the relationship between cutting conditions and the effects of cutting oils, and explain the thinking necessary for effectively using cutting oils. We hope you will participate and find it useful for your daily activities. We will introduce other lecture contents tomorrow. <Schedule> Date: February 7, 2025 (Friday) 10:00 AM - 5:00 PM (Login starts at 9:30 AM) <Registration Method> *Pre-registration required Participation Fee: Free Registration Deadline: January 31, 2025 (Friday) <URL for Information> https://www.idemitsu.com/jp/business/lube/news/240106.pdf
