"Cutting oils" can minimize the friction heat generated between the tool and the workpiece due to the lubrication function of the cutting oil. Furthermore, the cleaning function removes chips and grinding debris generated during processing from the processing area, preventing surface scratches caused by chips sticking to the cutting edge and preventing grinding burns and scratches caused by clogging of the grinding wheel. As a disadvantage, in the case of water-soluble cutting oils, especially during the rainy season and summer when temperatures rise, the cutting fluid is prone to spoilage due to anaerobic bacteria, leading to unpleasant odors in the workplace and necessitating oil replacement. To promote a circular economy, how to incorporate the 3Rs (Reduce, Reuse, Recycle) of waste oil regarding this disadvantage will be a future challenge. [Advantages] ■ Minimizes friction heat generated by the lubrication function ■ Cools friction heat and processing heat, dispersing heat away from the processing area ■ Maintains processing quality by preventing the formation of built-up edges on the tool's cutting edge ■ Prevents grinding burns and scratches caused by clogging of the grinding wheel due to grinding debris *For more details, please refer to the PDF document or feel free to contact us.

• Cutting Oil

When selecting cutting oils, it is important to consider what materials will be processed and how they will be processed, as well as the impact of long-term use of cutting oils on the surrounding environment. In recent years, improvements in workplace environments have progressed, and looking at the trends in domestic cutting oil shipments, non-water-soluble cutting oils are gradually decreasing, with shipments of water-soluble cutting oils already exceeding half. Additionally, there are movements to improve non-water-soluble cutting oils, such as reducing viscosity and increasing flash points, but from a long-term perspective considering the impact on workplace environments and responses to decarbonization and SDGs, it is expected that the trend of selecting environmentally friendly water-soluble cutting oils will continue.

• Cutting Oil

Non-water-soluble cutting oils are used in their concentrated form, and the cooling properties are adjusted based on the components of the concentrate. In the case of water-soluble cutting oils, they are diluted with water to the appropriate concentration for use. The concentration of water-soluble cutting oil in actual processing environments is adjusted according to the workpiece and processing method. There are three types of water-soluble cutting oils in order of increasing oil concentration: emulsion, soluble, and solution. Emulsion is the closest to non-water-soluble cutting oils, while soluble is generally used as the main type. *For more details, please refer to the PDF materials or feel free to contact us.*

• Cutting Oil

Cutting oils can be categorized into water-soluble cutting oils, which are designed to be diluted with water, and oil-based non-water-soluble cutting oils. Initially, only non-water-soluble cutting oils were used to prevent tool burning and tool wear. As the era of mass production began, the demand for increased processing speeds grew, leading to the development of ceramic tools such as carbide tools that enabled high-temperature cutting. However, oil cooling could not keep up with the cooling demands and posed a fire risk, which led to the practical application of water-soluble cutting oils that allow for rapid cooling. Oil-based cutting oils excel in lubricity and penetrability, achieving finishing precision, possessing rust resistance, and being less prone to spoilage. In other words, non-water-soluble cutting oils have excellent cutting functions, while the development of water-soluble cutting oils has progressed from the perspective of how to incorporate the characteristics of oil. 【Features of Water-Soluble Cutting Oils】 ■ High cooling speed - Water has a specific heat that is twice that of oil, allowing it to absorb double the heat with the same volume of coolant. - The heat absorption capacity during water evaporation (latent heat of vaporization) is very large (the latent heat of vaporization of water is approximately 540 kcal/kg). *For more details, please refer to the PDF document or feel free to contact us.

• Cutting Oil

Cutting oils can be broadly classified into "non-water-soluble cutting oils," which are oil-based, and "water-soluble cutting oils," which are diluted with water. The composition of the two types differs significantly. "Non-water-soluble cutting oils" are basically used in their concentrated form, and the oils can be either mineral oils derived from petroleum or animal and vegetable fats. Mineral oils have high thermal stability, while fats excel in lubricity and permeability. Additionally, when heavy machining is performed, sulfur-based extreme pressure additives are added to the concentrated oil. In other words, "non-water-soluble cutting oils" consist of three types of components: mineral oils, fats, and extreme pressure additives, and the ratio of these components is adjusted based on the machining target and content. "Water-soluble cutting oils," on the other hand, are generally used by diluting the concentrated form to an appropriate concentration. They significantly enhance cooling properties with water, but to achieve lubricity based on water, mineral oils and fats are added. Furthermore, surfactants are included to solubilize, emulsify, and enhance permeability of the oil in water, along with rust inhibitors and preservatives to prevent rust and spoilage due to oil-water mixing. *For more details, please refer to the PDF document or feel free to contact us.*

• Cutting Oil

Cutting oils can be categorized into those based on oils such as fats and mineral oils, and those based on water that have added functions of lubrication, rust prevention, and preservation. The water-based ones are soluble in water, hence they are called "water-soluble cutting oils." Conventional cutting oils are oil-based and do not dissolve in water, so they are referred to as "non-water-soluble cutting oils." Regarding the types of cutting oils, according to JIS standards, there are four types of "non-water-soluble cutting oils" (one type without sulfur-based extreme pressure additives, and three additional types with sulfur-based extreme pressure additives depending on the amount added), and three types of "water-soluble cutting oils" (based on oil quantity: emulsion/soluble/solution). *For more details, please refer to the PDF materials or feel free to contact us.*

• Cutting Oil

When performing machining with lathes, milling machines, and grinding machines, applying liquid to the workpiece improves machining efficiency and finishing quality. The liquid used is typically a lubricant known as "cutting oil." Subsequently, due to the demand for improved machining efficiency, cutting fluids that can be diluted with water for rapid cooling were developed, and these are collectively referred to as "cutting fluids." In other words, cutting fluids are divided into oil-based non-water-soluble cutting fluids that can be used as is without dilution, and water-soluble cutting fluids that are used when diluted with water. In recent years, with the demands of industrial processing for QCD—namely high quality, high precision, cost reduction, and shorter delivery times—the importance of cutting fluids has also increased. Due to the differences in cutting fluids, not only finishing quality but also tool life and machining environment can be affected, making it essential to choose cutting fluids that are suitable for the machining methods and conditions. *For more details, please refer to the PDF document or feel free to contact us.*

"Semidry processing (MQL)" is a method that sprays cutting fluid in mist form at the processing point, significantly reducing the amount of oil used while maintaining cutting performance. There are two types of semidry processing: "water-soluble mist," which excels in cooling properties, and "oil mist," which excels in lubrication properties. The equipment from Cool Tech is designed for water-soluble mist. This document introduces "examples of equipment usage" and "four features of Cool Tech's water-soluble mist processing."
