Oil-type industrial cutting oil is also called industrial oil-based cutting oil, and it is divided into three types: mineral oil cutting oil (or compound oil), extreme pressure cutting oil and active cutting oil. The mineral oil used is kerosene, diesel, and light lubricating oil fractions. A certain proportion of animal and vegetable oil (5% to 10%) is added to the mineral oil as a compound oil, which is suitable for light-duty cutting. Extreme pressure cutting oil is added with sulfur, phosphorus and chlorine extreme pressure additives to meet the requirements of deep metal processing such as ferrous metals and gears. The active cutting oil is added with active sulfur and other compounds for deep processing such as deep hole drilling and tapping of high alloy materials.

    There is also a cutting fluid that is completely water, that is, electrolytically strong alkaline water. Strong alkaline water produced by strong alkaline water equipment, PH can reach up to 13--13.5

    Compared with cutting oil and water-based cutting fluid, the raw material of alkaline electrolyzed water is 100% water, the source is stable and the price is low, and the cost is only one tenth or less of the aqueous cutting fluid. It has excellent cooling and cleaning performance, no foaming and easy washing. At the same time, alkaline electrolyzed water has good anti-rust performance. Moreover, both cutting oil and aqueous cutting fluid contain organic compounds, oily agents, surfactants and other components, which have a destructive effect on human health and the environment, while alkaline electrolyzed water is harmless to the human body and the environment, and is an environmentally friendly and low-cost one. The cutting fluid can completely replace the aqueous cutting fluid in high-speed shallow cutting.
