Question: 1 / 400

What is the primary purpose of cutting fluid in manufacturing?

To enhance the color of the material

To cool and lubricate the cutting tool

The primary purpose of cutting fluid in manufacturing is to cool and lubricate the cutting tool. When machining materials, the process generates significant heat due to friction between the tool and the workpiece. This heat can lead to tool wear, reduced tool life, and can affect the quality of the machined surface. Cutting fluids help dissipate this heat, maintaining suitable temperatures to ensure optimal performance of the cutting tool.

Additionally, cutting fluids provide lubrication, which reduces friction and wear on the tool, allowing for smoother cuts and prolonging the life of the tool in the machining process. The cooling and lubrication properties of cutting fluids are essential to achieving better surface finishes, increased machining accuracy, and prolonged tool life, ultimately enhancing productivity in manufacturing operations.
