Different metal materials in the process of processing will be different machine tools, metal cutting in the choice of cutting fluid, not only to consider metal materials, but also take into account the requirements of the machine tool for cutting fluid, both of the combination of the choice of a suitable cutting fluid. When selecting cutting fluid, we must consider whether the structure of the machine tool is suitable. Some machine tools, such as multi axis automatic lathe and gear machining machine, have taken into consideration the use of oil based cutting fluids, so there is no special bearing seal cover and special devices to protect the internal mechanism from outside water and steam, and the machine tools mostly rely on oil based cutting fluid to lubricate the cutting area. For moving parts, water-based cutting fluids must be used. If the water base cutting fluid, the water solution is permeated into the bearing and the internal structure of the machine tool, the components will be deoiled, resulting in corrosion and accelerated wear. The infiltration of water based cutting fluid into the hydraulic system will make the hydraulic oil emulsified into the emulsified liquid of oil or water, which makes the viscosity increase or decrease greatly, changes the nature of hydraulic oil and affects the normal operation of the hydraulic system. Therefore, for those machine tools originally used for oil-based cutting fluids, they must be cautious when transferring to water-based cutting fluids. If necessary, they will be destroyed.
