• MQL machining
• Inconel 718
• Control of oil-mist flow

Minimum quantity lubrication (MQL) machining is one of the promising solutions to the requirement for decrease in cutting fluid consumption. This paper describes MQL machining in a range of oil consumption <1.0ml/h, which is 10-100 times smaller than the consumption usually adopted in industries. MQL machining in this range is called micro-liter lubrication machining in this paper. A specially designed nozzle was used for concentrating small amounts of oil mist onto the cutting interface. The performance of concentrated spraying of oil mist in micro-liter lubrication machining of Inconel 718 was investigated and compared with that of ordinary spraying. This proved that the concentrated spraying of oil mist with a specially designed nozzle was quite effective in increasing tool life in the micro-liter lubrication range.
