1) Lubrication

Metalworking oil can form a layer of lubricating film between the surface of the tool and the workpiece, which can reduce or avoid direct contact between the tool and the workpiece, reduce the degree of friction and adhesion, and thus reduce tool wear and improve the machining quality of the surface of the workpiece.

2) cooling

During the cutting process, the metal processing oil flowing out of the cutting area takes away a lot of heat, thereby reducing the temperature of the workpiece and the tool, improving the durability of the tool, reducing thermal deformation, and improving processing accuracy. However, the impact of metalworking oil on the interface between the tool and the chip is not large. Experiments have shown that the metalworking oil can only reduce the high temperature area of the interface between the tool and the chip, and cannot reduce the maximum temperature. The general casting method mainly cools the chip. If metal processing oil is sprayed behind the tool pair, the cooling effect of the tool and the workpiece will be better.

3) Cleaning

During turning, milling, grinding, drilling, etc., metal working oil is often poured and sprayed to clean chips and debris on the machine tool and remove the chips and debris.

4) Rust prevention

Some metal processing oils are added with rust preventive additives, which can react with the metal surface to form a protective film, thereby preventing rust. Metal processing oil
