The article presents the problem of cleaning effectively lubricant - coolant fluid using two different metal-working techniques. Compared with lubricant-coolant fluid, the use of steel abrasive tools produces very small steel particles having relative weight. Steel processing with diamond polishing tools does not make chips. The paper considers theoretical cleaning methods and compares them with experimental results cleaning an additional flow of lubrication and cooling with a magnetic separator and hydro-cyclone.
