Study Of New Method And Equipment Of Combined Machining Based On High Temperature Alloy

Such new materials as high-temperature alloy have high hardness, high strength, high wear ability and high functional. These new materials are applied extensively to aviation, craft and chemical industry already now. Most of them are difficult to process by its nature we can know. So how to process them with high quality and high efficiency has become a badly difficult problem in need of solution.The paper summarized application and grinding characteristics of such difficult-to-grind materials as high-temperature alloy and so on in detail. And the paper has described current situation of research, development and application of different relevant processing technologies. According to characteristics of heavy toughness plasticity and strong seizing and low grinding efficiency of high-temperature alloy, for improving grinding efficiency of difficult-to-grind material, the paper have put forward a new design philosophy of mechanical electrolysis-electro discharge system machining (MEEC) and described machining theory.After proposing design viewpoint of processing equipment of the new method, the paper mainly researched, designed or analyzed and chose special work electrode—slot CBN emery wheel needed in experiment, special-purpose treatment fluid and special-purpose pulse power source needed in electricity's compound repairing. The paper also has explained their importance; developed slot CBN emery wheel according to the needs for combined machining in new method; analyzed and described the theory of paring intermittently and in-process dressing. Comparing the impact on processing results of various kinds of the treatment fluid, combining comprehensive function of MEEC, the paper has verified and chosen a kind of suitable special-purpose treatment fluid used in combined machining. Comparing power source used in various kinds of processing methods, according to characteristics of MEEC, the paper has proposed function requirement of power source and designing requirement of main electric parameter. The paper has...
