Green manufacturing by using organic cooling-lubrication fluids

Abstract

The global competition and trends force the manufacturing industry players to permanently innovate, reduce costs and become more environmentally friendly, thus the pressure for eco-friendly, sustainable and more reliable products is rising. The environmental concerns have begun to be increasingly included in sustainable development strategies of the companies since the effects of worldwide pollution have become more and more visible. In manufacturing industry, in machining units, the cutting fluids are an important source of expenses and they can also be a threat for environment and employee’s health. This paper presents a study regarding the possibility of replacing the traditional flood cooling in hard turning with minimal quantity lubrication using vegetable biodegradable oils since the scientific community has brought many contributions to the phenomenon of replacing grinding with hard turning. The capability of hard turning to replace grinding in many industrial applications is proved and thus the elimination of harmful coolant and transition to biodegradable cutting fluids seems to be the way of the future in machining.
