What is the role of cutting fluids in CNC machining?

Cutting fluids play a crucial role in CNC machining primarily by cooling the workpiece and lubricating the cutting tool. During machining operations, friction between the cutting tool and the material generates heat, which can lead to thermal expansion, tool wear, and dimensional inaccuracies. By applying cutting fluids, the heat is dissipated more effectively, helping to maintain a stable operational temperature. This cooling effect not only protects the integrity of the workpiece but also helps extend the life of the cutting tool by reducing wear.

In addition to cooling, cutting fluids provide lubrication, which minimizes friction between the cutting tool and the workpiece. This lubrication allows for smoother cutting action, which can result in better surface finishes and improved machining accuracy. Overall, the combination of cooling and lubrication contributes significantly to the efficiency and effectiveness of the CNC machining process.
