Compared with others, the machining method of EDM is special. It can be used for triangular holes and porous materials, especially some hard materials such as steel. Therefore, the position occupied by EDM is very important in the processing industry.
There are many EDM machine tool manufacturers have high technical content and low cost, and it is difficult to guarantee the quality of their products. In the processing of EDM machine tools, the parts must be processed more regularly and smoothly. How to judge the discharge state?
- 1. The electrical discharge machine is composed of many single-pulse electrical discharge process microstructures. Including the north and south poles, a breakdown of the ionizing medium between the normal single pulse discharge process, forming a discharge channel, the instantaneous temperature in the discharge channel where the working fluid is vaporized, cracking, the metal material is melted, evaporated, and the high voltage makes it instantaneous The working fluid thrown into the machining debris, due to the deionization of the medium between the magnetic poles when the pulse discharge is completed, restores the process clutter insulation. The basic state of the discharge gap in each discharge pulse in the discharge condition called EDM.
- 2. Because whether the discharge state of EDM is stable or not is closely related to the machining quality, it is also one of the ways to determine the machining effect. Therefore, EDM has always been a concern of engineers and technicians. How to achieve safe and stable EDM is also A hot issue in the field of EDM This article starts from years of experience in EDM, discusses the phenomenon of unstable discharge in EDM, analyzes the causes of unstable discharge, and proposes improvement measures.
