WCEDM(Wire cut Electrical Discharge Machining referred to as WCEDM), which belongs to the category of electrical processing, was discovered by the former Soviet Union's Razalinko couple to study the phenomena and causes of damage caused by spark erosion of switch contacts, and discovered that the instantaneous high temperature of spark can make local metal Molten, oxidized and eroded away, creating and inventing EDM methods. The wire cutting machine was also invented in the former Soviet Union in 1960, and China was the first country used for industrial production. The basic physical principle is that free positive ions and electrons accumulate in the field and quickly form an ionized conductive channel.

Working principle

 A certain discharge gap is always maintained between the workpiece and the electrode wire and the working fluid is sprayed. The spark discharge between the electrodes erodes a certain gap, and a continuous pulse discharge cuts out a workpiece of a desired shape and size.
