MQL Application in Reaming - A Review

Prof. S.C.Borse, K.S.Bansode

The purpose of this article is to review the relevant literature in reaming using minimum quantity lubrication. Modern machining requirements often demand mass production of holes with good surface finish and geometrical accuracy which are needed for precision assembly. Near about 100 million gallons of metal working fluid is used for machining operation of various parts. Maximum machining operation parts are created under flood lubrication but flood lubrication contributes to adverse health effect and safety issues, including toxicity, lung diseases to operator and air pollution etc. In order to minimize the use of cutting fluid the Minimal Quantity Lubrication (MQL) technology was introduced. MQL is the process to apply minute amount of lubrication to the tool tip. The lubricant is mixed with compressed air and forms aerosol mixture called as MQL. According to the various literatures, the use of MQL technology resulted in decrease of overall cost by about 13 percent and it is possible to achieve effective lubrication of cutting process with extremely small quantity of oil. The result is not only high productivity but also longer tool life and cost saving.
