PT Journal AU Popov, A Khramenkov, M TI Effect of Hydraulic Oil Entering the Cutting Fluid on the Tool Life and Roughness in Turning of Stainless Steel SO Manufacturing Technology Journal PY 2019 BP 664 EP 667 VL 19 IS 4 DI 10.21062/ujep/352.2019/a/1213-2489/MT/19/4/664 DE Turning; Cutting fluid; Wear; Roughness AB The use of cutting fluid should positively influence on the quality of the machined surfaces and durability of cutting tools. However, during the machining the oil from the hydraulic system of the machine often gets into the cutting fluid, which can alter the properties of the cutting fluid. In scientific literature there is no information about the effect of the hydraulic oil entering the cutting fluid on the tool life and roughness in turning. In this regard, at the laboratory of the Department of Machining and Assembly of the Technical University of Liberec, there has been conducted a study to ascertain the effects of hydraulic oil getting into different types of cutting fluids during the turning of stainless steel.
