In this master thesis, emulsions for machine tools are theoretically processed, and in the practical part, the adhesion wear test of the aluminum sample was performed with the use of various emulsions and without the use of coolant, rinsing and lubrication. The types of cooling, rinsing and lubricating agents (emulsions, oils, synthetic and semi - synthetic agents) are described, as well as the choice of SHIP during various treatments (deformation treatment, heat treatment, etc.). The properties and influence of individual SHIPs on temperatures and service life of work tools are stated. Various examples of harmful consequences caused by insufficient lubrication or impurities that occur without regular maintenance of the emulsion supply system are presented. In addition to the theoretical part of this thesis, an experiment was conducted, testing the effect of different emulsions on the wear of test specimens and cutting inserts used in its performance. The experiment was conducted on five levels, using four different types of emulsions, and conducting the experiment without the use of coolants, rinses and lubricants. A total of nine test specimens and five different cutting inserts of approximately identical properties, were used. Input parameters and response were predetermined for the test, so that all results were comparable. Also, the methods of procurement, storage and handling of coolants, rinsing and lubricants for the purpose of protection at work are defined, as well as the harmful effects of improper handling.
