Main purpose and scope of application
Widely used in mold manufacturing, electronic instruments, precision machinery, auto parts, magnetic materials, nuclear industry, aerospace and military industries.
It is mainly suitable for processing various stamping dies, powder metallurgy dies, injection dies, wire drawing dies, corrugated plate forming dies and other dies.
It is suitable for machining micro holes, special-shaped holes, special-shaped grooves, narrow slits, standard missing parts, gears and complex parts processing.
Suitable for processing high hardness alloys, magnetic materials, precious metals.



WEDM take wire (Molybdenum wire or Tungsten and Molybdenum alloy wire ) as electrode, working liquid as media, Electrical discharging happened between the electrode and the work piece by using of the high frequency impulse power and the high peak current to bring high heat and high energy to erode the work piece. The preconceived track of the wire is controlled by the moving of X-Y axis and U-Y axis which are driven by the machine. Then the work piece is processed.



Medium speed wire cut EDM is a new generation of EDM machines which are widely used in the fields of moulds, automobile parts, aeronautics and astronautics, electronic instrument, military, light industry, and household appliances.
