Estimation of efficiency of catches coolant in grinding

The last years in our country are also abroad conducted the active scientific research directed to enhancement methods of supply the liquid lubricant-coolant (LLC) and application of different types energy impact on it. Features of application LLC case of abrasive handling are connected with specifics design of the tool, the modes and handling method. The main actions of LLC: lubricant, cooling, washing, dispersing and anticorrosive. For today more than 2000 various methods of giving LLC known. Systematizing them, 30 main methods, considerable number of their versions and combinations were allocated. In article the protecting, combined and new combined-giving methods of the lubricant cooling technological liquidare considered. The protecting method intended for fight against a torch of waste it is directed by the main source of pollution moving from a zone of cutting and being in the working area, there was insufficiently effective in implementation of the main functions LLC. In the investigation of it the combined method of giving LLC which included the most effective methods of giving from known, for example, for freely falling stream and among the lubricant cooling technological liquidwas developed. As a result of trial operation at this method a number of shortcomings, such as a heavy consumption LLC the electric power, low efficiency was revealed when grinding spatial details. The new combined method was deve¬loped for elimination of these shortcomings. By results of experiments LLC moving by this method effectively performed the main functions, besides showed the catching action which consists in decrease density of harmful substances in the working area of the machine operator.
