Embodiment Construction
[0015] specific implementation plan
[0016] according to figure 1 , the abrasive water jet mirror turning experimental device is mainly composed of an abrasive water jet device, a displacement measurement device and a fixture device. The water is pressurized to ultra-high pressure through the supercharger, and then enters the mixing chamber of the high-pressure nozzle 4 through the small-hole water nozzle to form a high-speed water jet, and a certain degree of vacuum is generated in the mixing chamber. The bucket 6 is sucked into the mixing chamber through the sand inlet pipe 5, produces violent turbulent diffusion and mixing with the water jet, forms a high-speed abrasive jet, and acts on the ceramic material workpiece through the abrasive nozzle at a very high speed. The abrasive jets ejected from the two high-pressure nozzles 4 arranged as mirror images of the workpiece material can not only support each other, offset part of the cutting force to reduce workpiece deformat...

Description
technical field [0001] The invention relates to an experimental device for abrasive water jet mirror turning, in particular to an experimental device for abrasive water jet mirror turning of engineering ceramic materials, through which the engineering ceramic materials are turned. Background technique [0002] Engineering ceramic materials (alumina, zirconia, etc.) have excellent properties such as high hardness, high strength, corrosion resistance, wear resistance, heat insulation, and good chemical stability. They are used in military, aerospace, atomic energy, space technology, and manufacturing fields. Applications are increasingly widespread. However, due to the inherent properties of high hardness, high brittleness and low fracture toughness of engineering ceramic materials, its processing technology is much worse than other materials, and it is easy to produce small cracks and stress concentration phenomena during mechanical processing, resulting in ceramic parts. Th...
