Cutting oil are essential lubricants used in metalworking operations to improve the performance of cutting tools, increase tool life, and improve the quality of the finished product. Cutting oils are used in various metalworking applications, including turning, drilling, milling, and grinding. In this article, we will discuss the basics of cutting oils, including the types and applications.

Types of Cutting Oil

Mineral Oil-based Cutting Oil

Mineral oil-based cutting oils are made from refined crude oil and contain additives to improve their lubrication and cooling properties. These oils are suitable for a wide range of metalworking applications, including cutting, drilling, and tapping. They offer excellent lubrication and cooling properties, which help to reduce heat and friction during cutting, extending the life of cutting tools.

Synthetic Cutting Oils

Synthetic cutting oils are made from synthetic base oils and contain additives to enhance their lubrication and cooling properties. These oils offer superior performance compared to mineral oil-based cutting oils, providing better lubrication, longer tool life, and improved surface finish. They are ideal for high-speed and high-pressure metalworking applications.

Semi-Synthetic Cutting Oils

Semi-synthetic cutting oils are a blend of mineral oil-based and synthetic cutting oil. They offer the benefits of both types of oils, providing good lubrication and cooling properties while also offering extended tool life and improved surface finish.

Applications of Cutting Oil

Turning:Cutting oils are used in turning operations to reduce friction and heat generated during the cutting process. This helps to extend the life of cutting tools and improve the quality of the finished product.

Drilling: In drilling applications, cutting oils are used to lubricate and cool the drill bit, reducing heat and friction and extending the life of the drill bit.

Milling: Milling operations generate a lot of heat and friction, which can damage cutting tools and reduce the quality of the finished product. Cutting oils are used in milling operations to reduce heat and friction, improve the surface finish, and extend the life of cutting tools.

Grinding: Grinding operations generate a lot of heat and can cause damage to cutting tools. Cutting oils  are used in grinding applications to reduce heat and friction, improving the surface finish and extending the life of cutting tools.
