Functions of Cutting Fluid -

• To Cool The Tool - During machining operations, a lot of heat is generated. Cutting fluid helps to reduce that heat and cools the tool: this increases tool life and smooth machining operations.

• To Lubricate Moving Parts - Cutting fluid is also used as a lubricant so that tools can move easily. Frankly speaking, not only tools but cutting fluid can be used anywhere in the machine where there are moving parts.

• To Lubricate Moving Parts - Cutting fluid is also used as a lubricant so that tools can move easily. Frankly speaking, not only tools but cutting fluid can be used anywhere in the machine where there are moving parts.

• To Reduce Wear And Tear - Since cutting fluid helps is the smooth movement of parts in a machine, there will be less wear and tear. This increases machine life and tool life.

• To Clean The Tool And Machine - Cutting fluid is also used for cleaning the tool and machine. Especially in areas where cleaning is tough, cutting fluid spray jets helps to clean those areas.

• To Improve Surface Texture And Finished Part Quality - Since the cutting fluid is used as a lubricant, cleaner, and cooling medium, there are high chances that the surface texture of the finished part will have fewer foreign particles. This helps in gaining a smooth surface finish and improved parts quality.

• To Flush Away the Chips - Keep the cutting zone free from hot chips. Also to cause chips breakup into small parts.

• To Protect Machined Surface from Environmental Corrosion - Corrosion inhibitors like sodium nitrate or triethanolamine is added in the cutting fluids to prevent corrosion of the machined surface.
