To accomplish the successful Minimal quantity lubrication (MQL) machining, a very small amount of a cutting lubricant plays an important role. In this study, therefore, synthetic polyol esters with the oiliness are proposed as suitable fluids for MQL machining of aluminum alloy. In MQL machining, one should consider the effect of the lubricating ability of each ester itself on the cutting performance. However, there has so far been little investigation on the tribological behavior of lubricants for near-dry application in connection with their cutting performance. To understand the tribological characteristics of such lubricants, therefore, fundamental examinations are carried out with the aid of SRV test and the deep hole drilling. A newly developed fluid based on synthetic polyol esters demonstrates the satisfactory performance of MQL machining for aluminum alloy.
