How does the cooling effect of slurry work in the cutting process?

In metal cutting, slurry (cutting fluid) not only plays a role in lubrication and cleaning, but its cooling effect is also crucial. The cooling effect of slurry is closely related to the cutting process, and together they affect the processing efficiency, workpiece quality and tool life.
During the cutting process, the high-speed friction between the tool and the workpiece will generate a large amount of heat, which will lead to increased tool wear and thermal deformation of the workpiece, thus affecting the processing accuracy and surface quality. At this time, slurry, as a cutting medium, effectively absorbs and conducts the heat in the cutting area through its thermal conductivity, and quickly brings the heat in the high-temperature area to the low-temperature area, thereby achieving effective cooling of the cutting area.
The cooling effect of slurry not only directly reduces the cutting temperature, but also indirectly improves the cutting efficiency and tool life. In the cooled cutting area, the friction resistance between the tool and the workpiece is reduced, and the cutting force is correspondingly reduced, making the cutting process smoother and the cutting efficiency improved. At the same time, the cooling effect reduces the thermal wear of the tool, prolongs the tool life, and reduces production costs.
In addition, the cooling effect of slurry is complementary to the lubrication effect. During the cutting process, the lubricant components in the slurry form a lubricating film at the friction interface, which reduces the friction coefficient and further reduces the cutting heat and friction resistance. The existence of this lubricating film makes the cutting process smoother and the cutting heat is more effectively controlled.
In summary, the cooling effect of slurry plays a vital role in the cutting process. It not only directly reduces the cutting temperature, improves the cutting efficiency and tool life, but also works synergistically with the lubrication effect to jointly optimize the cutting process. Therefore, in metal cutting processing, choosing the appropriate slurry formula and cutting parameters to give full play to the cooling and lubricating effects of slurry is of great significance for improving processing efficiency, ensuring workpiece quality and extending tool life.
