In machining processes, what is the role of cutting fluid?

In machining processes, the role of cutting fluid primarily involves cooling and lubricating cutting tools. When cutting metal or other materials, significant heat is generated due to friction between the cutting tool and the workpiece. The cutting fluid plays a vital role in dissipating this heat, which helps to prevent tool wear and prolongs the life of the cutting tool.

Moreover, the lubrication provided by the cutting fluid reduces friction further, allowing for smoother cuts and improved finish on the workpiece. This dual function of cooling and lubrication is essential for maintaining efficiency and effectiveness in machining operations.

While preventing rust, cleaning surfaces, and filling gaps may have some relevance in a broader context of machine maintenance and operation, they do not encompass the primary purpose of cutting fluid in machining processes. Cutting fluids are specifically designed to handle the thermal and frictional challenges faced during cutting operations, hence the emphasis on their cooling and lubricating properties.
