The wire cutting machine is mainly composed of three parts: machine tool, numerical control system and high-frequency power supply. The numerical control system is composed of single-chip microcomputer, keyboard and frequency conversion detection system, with main functions such as gap compensation, linear interpolation, arc interpolation, and automatic processing of broken wires. It can cut materials such as high strength, high toughness, high hardness, high brittleness, magnetic materials, as well as precision small and complex parts. Wire cutting technology and wire cutting machine tools are being widely used in all walks of life.
