With the continuous development of science and technology and the mechanical processing industry, some new and high-performance engineering materials have been widely used. These materials mostly belong to difficult to cut materials with poor machinability, which brings difficulties to cutting processing. In order to solve the machining difficulties of difficult to cut materials, in addition to selecting tool materials, tool geometric parameters, cutting parameters, and mastering cutting conditions such as operating techniques, how to correctly select and use cutting fluids has also become an important link in mechanical machining.
The lubrication performance of oil-based cutting fluid is good, but the cooling effect is poor. Compared with oil-based cutting fluids, water-based cutting fluids have relatively poor lubrication performance and better cooling effect. Slow cutting requires strong lubricity of the cutting fluid. Generally speaking, oil-based cutting fluid is used when the cutting speed is below 30 m/min. Cutting fluids containing extreme pressure additives are effective for cutting any material when the cutting speed does not exceed 60 m/min. During high-speed cutting, due to the large amount of heat generated and the poor heat transfer effect of oil-based cutting fluid, the temperature of the cutting area will be too high, resulting in smoke, fire and other phenomena of cutting fluid. In addition, because the workpiece temperature is too high, thermal deformation will occur, affecting the machining accuracy of the workpiece, so water-based cutting fluid is often used.
The concentration of water-based cutting fluid should be controlled within the specified range to ensure that various properties meet the requirements. The concentration can be determined by refraction, oil content of lotion or determination of a specific component (such as base number and alcohol amine content). Determine whether to add water or concentrate after a period of use through concentration measurement.
