Characteristics:
• Oil-based coolants provide superior lubrication, especially for heavy-duty machining applications.

• They offer excellent surface finish and are suitable for operations requiring high heat dissipation.
• Oil-based coolants are commonly used for machining tough alloys and stainless steels.

Semi-Synthetic Coolant:

• Setup : Set up a machining operation such as milling or turning.
• Demonstration : Use a semi-synthetic coolant, which is a blend of synthetic and oil-based coolants, mixed
with water. Apply it during the machining process.
Characteristics:

• Semi-synthetic coolants combine the benefits of synthetic and oil-based coolants, offering good lubrication
and cooling properties.
• They are versatile and can be used for a wide range of machining operations on various materials.

• Semi-synthetic coolants provide stability and extended tool life while being cost-effective.
