Use MQL internal supply for drilling, reaming and tapping with large l/d ratios • EXPLANATION: Internal supply is beneficial in drilling, reaming and tapping with large l/d (length / diameter) ratios or or operations with multiple tools with very different dimensions. It’s indispensable in deep hole drilling. Internal supply eliminates nozzle positioning errors, and cleans the machining area of supply pipes. The disadvantage is the requirement of sufficient quantity of the medium available when cutting operation begins. Try to allow both, internal and external supply. • CLASSIFICATION: • Topic: COOLANT AND LUBRICANT • Machine Structure: COOLING SYSTEM • Life Cycle phase: USAGE • Type of machine tools: DRILL • Material selection: - • KEYWORDS: MQL, minimum quantity lubrication, coolant supply • SOURCES: Weinert, K., Inasaki, I., Sutherland, J.W., Wakabayashi, T. “Dry machining and minimum quantity lubrication”, 2004 • LINKS: • FIGURES/GRAPHS: 048
