What is the primary function of a cooling system in CNC machining?

The primary function of a cooling system in CNC machining is to reduce heat generated during cutting. During machining operations, friction between the cutting tool and the workpiece generates significant thermal energy. This heat can adversely affect not only the machining process but also the integrity and lifespan of both the cutting tool and the workpiece material.

By dissipating this heat, the cooling system helps to maintain optimal cutting temperatures, preventing overheating that could lead to tool wear, workpiece distortion, and compromised dimensional accuracy. Additionally, effective cooling can improve chip formation and evacuation, enhancing the overall quality of the machined surface.

While increasing the cutting speed, facilitating tool changes, and speeding up the machining process might have their own merits, they do not encompass the primary role of the cooling system in ensuring effective machining conditions and prolonging the lifespan of the tools used.
