The electric corrosion phenomenon in EDM was discovered as early as the end of the 19th century. For example, the electric spark generated when plugs and switches are opened and closed will damage the contact surface. In the early 20th century, when Lazarinco of the Soviet Union was studying the phenomenon and causes of spark discharge corrosion damage to switch contacts, he found that the instantaneous high temperature of electric sparks would melt and vaporize local metals and be eroded away, thus pioneering and inventing Electric discharge machining method, and in 1943, the world's first practical electric discharge machining device was developed by using the principle of electric erosion, which really applied the phenomenon of electric erosion to actual production and processing. China began to study EDM equipment in the early 1950s, and developed the first imitation-shaped wire-cut EDM machine in the early 1960s.
EDM is a new process that uses electrical energy and heat to process, commonly known as electrical discharge machining. edm machining service The difference between EDM and general cutting is that the tool does not contact the workpiece during EDM. Instead, it relies on the continuous pulse discharge between the tool and the workpiece. The local and instantaneous high temperature generated by the discharge is used to gradually reduce the metal material. Eclipse down. Because there are visible sparks during the discharge process, it is called EDM.
