Wire cut Electrical Discharge Machining (WEDM) belongs to the category of electrical processing. When the former Soviet Union Lazarinko and his wife studied the phenomenon and causes of the corrosion damage of the switch contacts by spark discharge, they found that the instantaneous high temperature of the electric spark can make the switch contacts damaged. The local metal is melted, oxidized and corroded, thus creating and inventing the electrical discharge machining method. my country was t

The system modules are connected by CAN BUS,  Modular design and high integration ensure the operation stability of system. Close-loop servo system designed independently for EDMadapts various operation conditon, the minimum control precision is 1um. Servo module is installed on themain engine，motor control andsignal feedback lines need not connect to control system,wich greatly reduce the complexity of installation technology.

EDM is a special machining method that uses the electro-erosion effect generated by the pulse discharge between the two poles immersed in the working fluid to erode conductive materials. In 1943, the Soviet scholars Lazarenko and his wife researched and invented EDM, which developed rapidly with the improvement of pulse power supply and control system. The first pulsed power supplies used were simple resistor-capacitor loops. In the early 1950s, it was improved to circuits such as resistance-in

1. EDM X-axis lateral processing of split molds has unique advantages, high mold clamping accuracy, and productivity can be increased by 20% compared with Z-axis downward processing 2. A single EDM electrode is used for rough and finish machining, which saves the manufacturing time and cost of double electrodes, saves the trouble caused by finishing electrode calibration, and shortens the mold manufacturing time. 3. The general pulse power supply of EDM in cavity machining is to transmit a ser
