Which advantages offers the Minimal Quantity Lubrication (MQL) over coolant lubrication?

0

• Higher productivity (20 to 70 % shorter machining times as a result of higher cutting values) • Less wear (the tool’s service life is increased by as much as 300 %) • Improved surface quality (less surface roughness) as a result of 100 % lubrication • Virtually dry process (chips, tool, working environment, no drag-out losses) • Health benefits (skin, respiratory tract, concentrations << MAC) • Ecofriendly (no waste disposal issues, no risk of water pollution) • Clean environment (staff satisfaction + motivation, operational safety) • Short amortisation periods
