The Wire Cutting EDM uses a single-strand metal wire (Moly or Tungsten Moly) as one tool electrode and work-piece as the other, with a dielectric liquid separated them. Under the high frequency impulse power, electrical discharge happens between the tool electrode and the work-piece. This electric spark produces intense heat with high temperatures, melting the work-piece. As the machine table travels in the direction of X-Y and U-V, the spark jumps across the gap in the pre-setup direction, material is removed from the work-piece and the profile is completed.

The machine is well designed in with Ergonomics and modern construction. It is easy to be operated with super performance. The machine with stronger body and stability carries heavier work-piece. The lower cutting force and higher safety protection make the machine welcomed by operators. It can be used for any metal moulds, samples or parts with complicated profiles, which requires high precision, hardness and toughness. It is the best tool for the processing of stamping, extruding or injection mold, plastic mould, hob cutter, precision parts (including parts with big taper, equal or unequal taper, different profile upper and lower end), heavy load and thickness mould.

Jingzhou Mind Science and Technology Co.,Ltd. Jingzhou Mind Science and Technology Co.,Ltd.

The machine is widely used in mould, electronic device, precision machinery, automobile components and military industry.

The large taper devices increase the processing capacity of mould and die for different products, which includes but not limited to extruded plastic or aluminum profile for window frame, auto parts, framework of television and washing machine.
