Abstract
The invention relates to material machining methods, in particular to a method for cooling down a cutting area. The inventive method consists in supplying a gaseous lubrication and cooling medium which is pre-treated by means of an ionised in an electric discharge field. Said gaseous lubrication and cooling medium is supplied under a pressure which is equal to or higher than 0.04 atm and is provided in the form of a jet whose length at the ioniser output is less than 30 diameters. The N jets of the gaseous lubrication and cooling medium are formed, N being selected from a relation N=P/K, wherein N is the number of jets, P is a cutting power in kW, K is a cutting power value per jet of the gaseous lubrication and cooling medium at which the life of a cutting tool is equal to or greater than the life of said cutting tool cooled by a cutting lubricant fluid. The K value is selected from a range of 0.2-3.5 kW according to a processed material properties. The use of N-jets of the gaseous lubrication and cooling medium improves the cooling efficiency of the cutting area by enlarging the cooling space thereof and simultaneously increases the wear-resistance of the cutting tool.

Moreover, the value Κ is selected in the range from 0.2 to 3.5 kKt, depending on the properties of the processed material.
