Metalworking Coolants and Lubricants

Metalworking coolants and lubricants are technical fluids used in machining processes (such as turning, milling, grinding, and drilling) to cool and lubricate the cutting zone. They are essential for enhancing production efficiency and machining quality.

High temperatures and friction are generated during chip removal. These fluids serve to:

Reduce heat generated between the tool and the workpiece
Decrease friction and tool wear
Improve the surface finish of the machined component
Facilitate chip evacuation
Protect against oxidation and corrosion

These actions help extend tool life and maintain production process stability.

Main Types

Metalworking fluids fall into several categories based on their composition:

Straight oils (non-miscible)
Mineral or synthetic-based
High lubricating power
Ideal for heavy-duty operations and low speeds
Emulsions (oil-in-water)
Mixture of oil and water
Good balance between cooling and lubrication
Widely used in general machining
Synthetic solutions
Mineral oil-free
Excellent cooling capacity
High cleanliness and fluid longevity
Semi-synthetics
Combine characteristics of emulsions and synthetics
Good balance between performance and maintenance
