Description

technical field [0001] The invention relates to a mechanical vibration electrolytic processing device for deep and small holes with special-shaped cross-sections, and belongs to the technical field of electrolytic processing. Background technique [0002] A large number of research results have shown that cooling holes with surface microstructure features (such as micro ribs, micro grooves, micro bosses, etc.) can greatly increase the heat transfer effect of heat transfer equipment and enhance the thermal load borne by the equipment, thereby improving the performance of the equipment. the experimental lifespan. Therefore, processing cooling holes with enhanced surfaces has an important position in industrial production. [0003] In heat transfer equipment, many equipment materials are high-temperature alloys, which are difficult to form or have low forming efficiency by mechanical processing methods. In recent years, researchers have explored the use of special processing m...
