High-speed electric spark machining small hole process

October 19, 2018

In recent years, with the rapid development of science and technology, a large number of different types of small holes need to be processed. As we all know, the EDM process has been applied in production, but its processing range is greatly limited. Not only the processing efficiency is low, but also the processing depth is shallow. Generally, the ratio of hole depth to aperture is less than 10-20. This does not meet the needs of actual production, so seek a way to
