Announcement of Idemitsu's water-soluble cutting oil / GSC Award "Minister of the Environment Award" received.

Extended shelf life against decay and significant reduction in supply quantity! Well-received for reducing stickiness and suppressing mist.

**Awards** - Received the Technical Award at the 43rd Precision Engineering Society - Received the Grand Prize at the 21st 2024 "Super" Monozukuri Parts Awards - Received the Minister of the Environment Award at the 24th Green and Sustainable Chemistry Awards **Product Overview** The "Alpha Cool NV Series" is a water-soluble cutting oil that balances the improvement of the working environment with increased productivity. It is particularly well-received for significantly reducing stickiness on equipment and products, as well as for its effectiveness in suppressing mist and foul odors. Additionally, it has successfully reduced the amount of carry-off. In actual workplaces, it has been confirmed that the consumption of the concentrate has been reduced by an average of 40%. Along with improving the working environment, it contributes to reducing both usage and disposal amounts, thereby enhancing productivity on-site. The NV series offers two types: an emulsion type that accommodates a wide range of processing from non-ferrous to alloy steel, and a soluble type specialized for iron processing. **Features** - Improved resistance to spoilage, extending performance maintenance time by over 250% - Reduced carry-off, cutting concentrate consumption by 40% - Contribution to the environment and reduction of disposal costs - Enhanced safety for workers due to reduced oil mist *For more details, please refer to the PDF document or feel free to contact us.*

• Cutting Oil

An example of significantly reducing the supply amount due to extended decay life and a small amount taken away.

We would like to introduce a case where the water-soluble cutting oil "Alpha Cool NV Series" was adopted by Miyahara Co., Ltd. The company faced challenges in reducing running costs. By using our product, we proposed a reduction in usage and an improvement in anti-corrosion properties, which led to a decrease in costs and time spent on coolant management. After adoption, it was demonstrated that even with less than half the replenishment amount, the workability and stable pH (alkaline) were maintained. [Case Overview] ■ Customer's Challenge: Reduction of running costs ■ Manufactured Parts: Precision parts, food and medical parts ■ Work Materials: Stainless steel, iron, some aluminum ■ Type of Oil Used: Market soluble type *For more details, please download the PDF or feel free to contact us.

Reduce the supply amount of the concentrated solution to contribute to cost reduction and carbon neutrality! Improve stickiness in processed products and within equipment. Awarded the "Super" Manufacturing Parts Award.

The "Alpha Cool NV Series" is a water-soluble cutting oil that has completely re-evaluated the composition of surfactants, including the use of non-volatile amines. It achieves a longer shelf life for active ingredients and has been shown to reduce the amount of concentrate replenishment by an average of about 40% in workplaces that have adopted the NV series. 【Improvement Results with This Product】 ◎ Reduction in the amount of concentrate replenishment for water-soluble cutting oil (average of about 40% for emulsion types) ◎ Reduction of odors due to improved anti-corrosion properties ◎ Improvement in stickiness of products and equipment after processing ◎ Cost savings of about 1 million yen per year for every 30 processing machines *We are currently offering a free collection of case studies summarizing adoption examples. For detailed information, please refer to the "PDF Download" section. *Sample provision and demonstrations (by consultation) are also available. Please feel free to contact us for more details.
