Water-soluble cutting oil: Look in-depths

Water-soluble cutting oil is one of the industrial fluids that can help the production process of machinery work efficiently. Lubricating functions, Cooling the system, reducing friction, and preventing rust. With the maintenance of pesticides that can help to control the cause of bad smell.

How choosing a water-soluble cutting oil for the appropriate process and materials used in production will provide the most benefits in terms of both costs and compensation.

In general, Water-soluble cutting oils can form an Emulsion (Floating layer between oil and water) by emulsified oil solution These emulsifiable’s are concentrated mineral oils that contain an emulsifier, which acts as a molecular binder. between water and oil so that they can be combined It is in the form of an emulsion, the color of water-mixed cutting fluid. Most of them are white (like milk)

We can classify the type of Water-soluble cutting oils by 2 main categories, and 4 sub-categories. Like… 

1. Oil in water. (Emulsion, Soluble, Solution)
2. Water in oil. (Water soluble)

The basic composition of Water-soluble cutting oil consists of 4-main components: Water, Concentrated mineral oil, Emulsifier, and additives. From all of these four components, the emulsifier is the most important. It’s called a “Surface active agent” to make water and oil mix fully well and turn into a complete emulsion form. As known as “Soap oil”

In general, the form of the emulsifier is similar to a matchstick and can withstand temperatures of about 400°C, A high temperature when compared to water. But it may not be enough for the machining process. The temperature for machining is higher than 800°C, with most of the heat accumulating on metal cutting scraps and blades.

If the water-soluble cutting oil doesn’t have good heat resistance properties and can’t infiltrate between the metal cutting scrap and the blade to cool the cutting process. This will cause heat to accumulate on the metal turning scrap until it changes its internal stabilizer (pearlite to austenite). The metal turning scrap will melt at the tip of the cutting edge of the blade (Built-Up Edge).

IDEMITSU develops and designs an emulsifier that can resist the high temperature of more than 700°C of a cutting process, and the form of the emulsifier is designed like a 2-layer matchstick combined. It can extend the lifespan and reduce the amount of work process very well. And good for a long-running process in better ways.
