Machining involves cutting tools working at high force and temperature, which can lead to fracture or wear of the tool. Cutting fluids are used to cool the tool and workpiece, reduce friction, and remove metal chips. Cutting fluids contain various additives like boundary lubricants, anti-wear agents, and emulsifiers that perform functions such as reducing friction and corrosion. Proper filtration and maintenance of cutting fluids is important to maximize their tool protection properties and minimize contamination.
