When using MQL, implement safety systems to prevent fires or explosions

When using minimum quantity lubrication (MQL) in machining, the risk of producing an explosive mixture of dust and fine particles increases. This is exacerbated by high process temperatures and potential ignition sources, particularly under aggressive cutting conditions. To mitigate these risks, it's essential to implement safety measures such as enclosed workspaces designed to withstand explosion pressures, integrated pressure relief systems, and suitable automated fire extinguishing systems. These precautions are critical for ensuring a safer machining environment.

  1. When using MQL, implement safety systems to prevent fires or explosions • EXPLANATION: During the machining with MQL, an explosive mixture of dust and fine particles may be produced. Because of the high process temperatures an ignition source may be present, especially under aggressive processing conditions. Enclosed workspaces that would withstand the pressure of an explosion, pressure relief flaps integrated into the working area or suitable automated fire extinguishing systems are helpful measures that should be taken into account. • CLASSIFICATION: • Topic: SAFETY • Machine Structure: SAFETY SYSTEMS • Life Cycle phase: SELECTION OF COMPONENTS • Type of machine tools: GENERAL • Material selection: - • KEYWORDS: safety systems, MQL • SOURCES: Weinert, K., Inasaki, I., Sutherland, J.W., Wakabayashi, T. “Dry machining and minimum quantity lubrication”, 2004 • LINKS: • FIGURES/GRAPHS: 060
