Cutting Fluid

Cutting fluids are substances used in machining and metalworking processes to reduce friction and heat generation during cutting, drilling, milling, and other operations. They are part of the supply class Oils And Greases: Cutting, Lubricating, And Hydraulic, which falls under the supply group Fuels, Lubricants, Oils, And Waxes.

Cutting fluids serve several purposes, including:

1. Lubrication: They reduce friction between the cutting tool and the workpiece, preventing excessive wear and extending tool life.

2. Cooling: Cutting fluids dissipate heat generated during cutting, preventing the workpiece and cutting tool from overheating.

3. Chip evacuation: They help flush away chips and debris from the cutting zone, improving cutting efficiency and preventing chip buildup.

4. Corrosion protection: Cutting fluids often contain additives that protect the workpiece and cutting tool from corrosion, especially when working with ferrous metals.

5. Surface finish improvement: Some cutting fluids contain additives that enhance the surface finish of the machined part, reducing the need for additional finishing processes.

Cutting fluids can be classified into different types, including:

1. Straight oils: These are non-emulsifiable oils that provide excellent lubrication and cooling properties. They are typically used in heavy-duty machining operations.

2. Soluble oils: Also known as emulsifiable oils, these fluids are a mixture of oil and water. They can be easily mixed with water to form stable emulsions and are commonly used in general-purpose machining.

3. Synthetic fluids: These fluids are chemically formulated to provide superior lubrication and cooling properties. They are often used in high-speed machining and operations that require extreme pressure resistance.

4. Semi-synthetic fluids: These fluids are a blend of synthetic and mineral oils, offering a balance between performance and cost-effectiveness.

When selecting a cutting fluid, factors such as the material being machined, the machining process, and environmental considerations should be taken into account. It is important to follow the manufacturer's recommendations and guidelines for proper usage and disposal of cutting fluids.
