Causes and Treatment Methods of EDM Molybdenum Wire Breakage

EDM Molybdenum wire plays a vital role in the high speed and medium speed cutting processing. High-strength, low-elongation molybdenum wire is the guarantee of high efficiency and high stability processing. However, it is inevitable to encounter the problems of broken wire, burnt wire, and speckled wire in the actual processing process, we have summarized the following common phenomena and corresponding solutions.

Research on the machining of deep and small holes by small hole EDM drill machine with the ratio of depth to diameter greater than 1:100

The processing of deep and small holes with super large depth-to-diameter ratio has always been a difficult problem in the manufacturing industry. For small hole EDM drill machine, it is more difficult to process deep and small holes with a depth-to-diameter ratio of more than 100:1, especially those with a diameter of less than 1.0 mm. EDM deep and small hole machining is one of the more mature machining methods. Through a series of experiments (tests on brass/copper electrode tube), this paper expounds the feasibility of electric machining deep holes, making it possible to electric machining deep small holes and guaranteeing certain technical conditions.

The Analysis and Solution of speckled wire Phenomenon of EDM Molybdenum Wire

After a period of processing, the molybdenum wire EDM wire will appear dark and light-colored spots, sometimes arranged according to a certain pattern to form a pattern, so it is called speckled wire.

Selection and Suggestion of Filter Paper for EDM Filters

EDM machine tools are mainly used for the manufacture of various molds, electrodes, and precision parts, as well as the processing of complex cavities and curved surfaces of various conductive materials. It has the characteristics of high machining accuracy, high finish and fast cutting speed. Especially in medium-speed wire cutting machine tools and low-speed wire EDM machine tools, the filter plays a vital role in ensuring processing accuracy and stability.
