CUTTING FLUID: DEFINITION, PURPOSE, PROPERTIES, TYPES, APPLICATIONS, AND SELECTION

Cutting fluids are liquids that are used in metal cutting operations to prevent the production of heat and reduce friction between the cutting tool and the workpiece. They play a crucial role in the machining process by cooling the tool and the workpiece and providing lubrication, which helps to reduce the cutting force and improve the surface finish.

Machining operations generate a lot of heat, which is why a cooling fluid is required. Cutting oil is the best available option for this purpose as it helps to keep the temperature in check and prevent damage caused by heat.

Properties of cutting fluids

The common properties of cutting fluids include high heat absorbing capacity, high flash point, non-corrosiveness, good lubrication properties, and odorless stability. 

Cutting fluids are known for their high heat-absorbing capacity, which helps to prevent the temperature from rising and causing damage. The high flash point of cutting fluids makes them safer to use as it reduces the risk of fire. Cutting fluids are also non-corrosive to the equipment used such as the main tool and work material, ensuring their longevity and reliability. 

Good lubrication properties of cutting fluids help to decrease the frictional force and reduce power consumption, making them a vital component in metal cutting operations. When left in the air, cutting oils are stable and do not get oxidized or decomposed easily.

Different types of cutting fluids

There are four main types of cutting fluids: soluble cutting oil, neat cutting oil, synthetic coolants, and solid lubricants.

Soluble cutting oil is a type of cutting fluid that is soluble in water and is commonly used in large-scale operations. Neat-cutting oil is a type of cutting fluid that is not soluble in water and is ideal for small-scale operations. Synthetic coolants are cutting fluids made of synthetic materials and are used in applications where high performance is required. Solid lubricants are cutting fluids in a solid form and are used in high-temperature applications.

Cutting fluid applications

Cutting fluids are commonly used as a coolant, lubricant, and flushing fluid. 

• As a coolant, cutting fluids are often applied to cool down the cutting tool and the workpiece.
• As a lubricant, cutting fluids are used to lubricate the tools and machinery, reducing cutting force and friction. 
• As a flushing fluid, cutting fluids are used to wash off the chips and improve the surface finish.

Cutting fluids benefits

• Cutting fluids help to control the temperature during the metal-cutting process by absorbing heat and preventing damage to the tool and workpiece.
• Cutting fluids help to improve the surface finish of the workpiece by flushing away chips and reducing built-up edges.
• Cutting fluids are typically non-corrosive to the equipment used in the cutting process, helping to protect the machinery from damage.
• Cutting fluids provide lubrication to the cutting tool and workpiece, which helps to improve the movement of the tool and reduce wear and tear on the machinery.
• Cutting fluids can be used as coolants, lubricants, and flushing fluids, making them a versatile solution for a range of metal cutting operations.

Cutting fluid selection

The selection of cutting fluid plays an important role in the metal-cutting process and affects its performance. Therefore, it is advisable to select high-quality cutting oils to derive optimal benefits.

The right selection of cutting fluid primarily depends on the material to be cut and the tool used. It also depends on the type of operation, such as drilling or cutting, and the degree of cooling effect required.

Takeaway

Cutting fluids play a crucial role in the metal-cutting process as they help to prevent the production of heat and reduce friction. They come in various forms, including soluble cutting oils, neat cutting oils, synthetic coolants, and solid lubricants. Selecting the right cutting fluid is important and depends on the material being cut, the tool used, and the type of operation being performed.
