Description
Cutting oil is a specialized lubricant formulated to cool, lubricate, and protect cutting tools and workpieces during metalworking operations such as Drilling, Turning, Milling, Tapping, and Grinding. It reduces friction and heat generation, improving machining precision and extending tool life.
Variants
Cutting oils are generally categorized into the following types:
-
Neat (Straight) Cutting Oil
-
Undiluted mineral or synthetic oil, sometimes blended with sulfur, chlorine, or phosphorus additives.
-
Ideal for heavy-duty machining operations or difficult-to-machine metals (e.g., stainless steel).
-
Provides superior lubricity, but may require proper ventilation.
-
-
Soluble (Emulsifiable) Cutting Oil
-
Forms a milky emulsion when mixed with water.
-
Used in general-purpose machining with good cooling and moderate lubrication.
-
Economical and widely used in automated and CNC machines.
-
-
Semi-Synthetic Cutting Oil
-
Contains both oil and synthetic components.
-
Offers a balance of cooling, lubrication, and cleanliness.
-
Provides longer sump life and resistance to bacterial growth.
-
-
Synthetic Cutting Fluids
-
Water-based with no mineral oil content.
-
Best for high-speed applications where cooling is critical.
-
Environmentally friendly and low in mist generation.
