What is semi-synthetic cutting fluid?

Semi-synthetic cutting fluid is a novel type of cutting fluid positioned between synthetic cutting fluid and mineral oil cutting fluid. It integrates the merits of both while circumventing their drawbacks. Semi-synthetic cutting fluid is typically formulated through scientific blending of extreme pressure agents, rust inhibitors, mineral oil, and multiple surfactants, belonging to the new generation of semi-synthetic microemulsion water-soluble cutting fluids. This cutting fluid is free from sodium nitrite and chlorides, and possesses excellent lubricating and rust-preventive properties. It is applicable for the processing of multiple metal materials, encompassing ferrous metals such as cast iron, carbon steel, alloy steel, stainless steel, and high-nickel steel, as well as non-ferrous metals like copper, aluminum, and their alloys. Semi-synthetic cutting fluid demonstrates outstanding performance in both hard water and soft water and is suitable for a wide range of machining processes, including turning, milling, drilling, and boring. It can also be utilized in single machines and central cooling systems.
