The development of the elements in the machine-tool – tool – lubricant – work-piece system is not even. The improvement of one element forces the development of the others thus resulting in the progress of the whole system. The aim of the present paper is to shed light on the facts that the lubrication technologies used today are inefficient and pollute the environment. Therefore development of this area is inevitable. Among the present-day developmental trends MQL (Minimum Quantity of Lubricant) is one that promises immediate results. Hopefully, it will also bring about the total paradigm shift in the machine manufacture technology. In this work we show the results of our experiments in which we investigated the effect of different factors of the cooling system – the lubricant, the dosage of the lubricants and several complementary cooling factors as the spontaneously, the induced emission and the Doppler-cooling – for the demand of energy of the cutting. We have found that numerous variations of the different factors can decrease the demand of energy. The effects for the grain structure of the active volume of the cutting have been investigated, as well.
