Cutting Oil.com - Components of Cutting Oil

A detailed explanation of the components of "non-water-soluble cutting oils" and "water-soluble cutting oils"!

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 derived from petroleum-based mineral oils 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 oil 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.*
