Failure Analysis and Diagnosis of Spark Erosion Machine Tools

摘要

In recent years, along with the rapid development of industrial technology, the development of spark erosion technique becomes very important and plays a key role in the molding processing technology, especially under the situation when this technology is urgently needed. Based on the first-hand data from the production site, it is introduced here regarding the structure and the working principle of hcd500k spark erosion machine tool; at the same time, the common faults and problems of the pulse power and servo feed system are analyzed in details and proposed the solution on them. The detailed analysis is also given for the problems like the frequent poor discharge. The reasons and diagnosis methods are deeply studied as well. It is very helpful and supportive on providing evidence for minimizing the machine design defects and making continuous improvement in design. This paper is meaningful in helping machine tooling design to step into a higher level and having spark erosion machine tooling been improving continuously.
