What is the main purpose of cutting fluid in machining?

The main purpose of cutting fluid in machining is to enhance tool durability and cooling. Cutting fluid serves several essential functions during the machining process. It helps to reduce friction between the cutting tool and the workpiece, which minimizes wear on the tool. This reduction in wear contributes to increased tool life, allowing for longer periods of operation without the need for tool replacement or sharpening.

Moreover, cutting fluid assists in dissipating heat generated during machining operations. High temperatures can weaken the tool and the material, leading to poor surface finishes and potential workpiece damage. By effectively cooling the cutting area, the fluid helps maintain optimal cutting conditions, which is critical for achieving precision and quality in machining.

Cutting fluids also help remove chips and particles from the cutting zone, ensuring smoother operation and preventing potential binding or obstruction. Overall, the use of cutting fluids is fundamental to the machining process, significantly impacting tool longevity and the overall efficiency of operations.
