  • 摘要:This paper describes the wear features of indexable carbide P25 inserts when turning C45 steel with cutting speeds of 250-450 m/min in dry cutting conditions and in the presence of an emulsion mist (MQCL method). As the active component of the emulsion mist 5%, the aqueous emulsion of EMULGOL concentrate was used. While analyzing the size, shape and formation dynamics of tool wear, the larger dimensions were found for dry cutting. The statistical analysis of results allowed calculating the dependencies to determine the wear rates. The SEM analysis revealed significant oxygen contents at the contact areas that are due to high temperatures in the cutting zone. When cutting with the emulsion mist the presence of phosphorus and copper entering in EMULGOL concentrate was fixed directly on the wear areas. It suggests the possibility of using compounds included in the emulsion mist to form AW and EP films at the contact areas in the cutting zone.
