The article analyzes the methods of cleaning lubricants. Based on the analysis of the methods of cleaning lubricants (coolant), the hypothesis of the use of coolant cleaning by ultrasound is substantiated. The potential of this method is ease of use and a wide range of indicators of the degree of coolant purification. The issues of separation, dispersion and cavitation, as well as their influence on the process of coolant regeneration, are considered. A preliminary experiment was conducted. The results of the experiment are processed and presented. This experiment has shown the effectiveness of the proposed method.
