Optimization of minimum quantity lubrication in grinding with CBN wheels

The application of minimum quantity lubrication (MQL) to metal machining has emerged as an alternative means to reduce cutting fluid usage, leading to cleaner production. In grinding, although MQL is considered to be progress regarding the environment, its application is restricted due to excessive heat generation and wheel clogging, which reduce final product quality and increase tool wear. This chapter reviews the research using MQL grinding aimed at improvements in terms of both wheel cleaning (by using an additional compressed air jet) and cutting fluid reduction (by adding water to the MQL oil). © 2013 Woodhead Publishing Limited All rights reserved.
