Abstract

The invention provides a method and device for machining micro annular grooves through hollow laser and electrolysis in a combined mode, and relates to the field of micro-electrolytic machining. Conducting glass is used as a tool cathode, the critical decomposition voltage of electrolytic machining under laser radiation is reduced, electrolytic machining is carried out on a radiation area, and the size of an annular machining area is controlled through a laser beam changing system. The laser beam changing system can be used for changing the size of an annular groove within a certain range, flexibility and softness of machining are obviously improved, under the laser radiation, the critical decomposition voltage of electrolytic machining is reduced, electrolytic machining of the radiation area is achieved, machining precision of the micro annular groove is improved, and the method and device are applied to machining of micro annular grooves of various conducting metal materials.

Description

technical field [0001] The invention relates to the field of micro-electrolytic processing of manufacturing technology, in particular to a method and device for combined processing of micro-ring grooves by hollow laser and electrolysis. Background technique [0002] Tiny groove structures exist in fields such as household appliances, instrumentation, and precision molds. Its processing accuracy, processing quality and processing efficiency have a great influence on the performance, quality and manufacturing cost of the product. Usually, the processing of ordinary structures is mainly carried out by machining. However, microstructures are often relatively small, and their precision requirements are high, and it is difficult to meet the precision requirements through machining. [0003] The emergence of electrolytic machining provides a channel for the machining of microstructures. In practice, due to its advantages of no loss of tools, high production efficiency, good surfa...
