ОБРАБОТКА МЕТАЛЛОВ № 2 (63) 2014 60 ОБОРУДОВАНИЕ OBRABOTKAMETALLOV (METAL WORKING AND MATERIAL SCIENCE) N 2(63), April – June 2014, Pages 56–61 Study of efficiency of a steam generator for coolant supply Dorohov A.A. , Post-graduate Student Egorov S.A. , Ph.D. (Engineering), Associate Professor, e-mail: tmp@ivgpu.com Dementeva N.A. , Ph.D. (Chemical) Textile Institute of Ivanovo State Polytechnical University, 21 Sheremetev Avenue, Ivanovo, 153000, Russian Federation Abstract The design of a steam generator for cutting fluids supply (in a steam phase) into the zone of metals machining is described in the article. Efficiency of the device is examined; dimensional wear-out of the instrument is defined as the result of external steel cutting by a hard-alloy instrument. The volume of the steam generator chamber is 0,32 dm 3 . Coolant-cutting fluid consumption is 0,8 l/h. Output steam temperature is about 90 ˚С. Operation efficiency of coolant-cutting fluids is different and does not depend on the base. The best efficiency of water-and-oil emulsions Pressoil, Emulisol T and half synthetic fluids Progress 13К and Ivkor is proved bu the study. The process of the instru- ment wear-out is influenced by triboactive additives contained in cutting fluids. Keywords: steam generator, coolant-cutting fluids, wear. References 1.
