·  High precision: Cutting precision up to ±0.003mm. Most stable and precise linear guide and ball screws from the top manufacturer; solid casting frame to ensure the consistence and durability.

·  Fine Surface Finishing: Ra≤0.4μm without defects (cut once and refine twice). Multiple cutting function: Available to perform refine cutting.  Ra≤0.47μm with extra thick metal.

·  High efficiency: Consistent cutting speed over 200mm²/min. Max cutting speed up to 400mm²/min. The unique impulse power supply makes less worn-out or broken of wire.

·  Simple & Safety: Multi-function fixtures make it easier for parts with different profile. Less change over. 

Modular designed power and control system makes the operation and maintenance much easier with better consistence than similar machines. UVXY steering control.

Moly wire at consistent tension from start to end. Spray intelligence controlled without jam.

Innovated Technology

·  Patent intelligent high frequency power. “Closed Loop Nanosecond Electroless HF Control System” is the only one in China. The min pulse width 7 nanosecond, electricity current controlled up to 0.01A and the single max current is 1600A.

· Closed Loop Track Control System”. Grating ruler with 1um resolution assists the Posittec BSG Nanosecond feeding system. Track control precision up to ±0.002mm.

·  Wire Winding System without conductive block”. Conductive block removed from wire support frame and therefore it eliminates the friction between wire and conductive block. Hence no vibration or tension problem with wire and the winding is more steady and less wear out. Wire tension will be consistent from start to end.

·  Integrated Wire Guiding System and Floating Spray Nuzzle System”. It makes the close contact processing and wire walk through easier. Wire is enclosed by sprayed solution all the time. The volume of sprayed solution are accurately controlled from both upper and lower .


·  Resin cast machine body, steel HT250. Twice anneal for better durability.

·  Main axis driven by hybrid motor.

·  Equipped with BSGXP designing and controlling software, WINDOWS XP based system, Plug-in supported, can be integrated with most designing software.

·  Data exchange and remote control supported.

·  Accurate digital high frequency power, notch impulse, improves the cutting efficiency and reduces wire consumption.

·  Power and driving system with patent makes it possible for high-speed cutting and revising.

·  Newly designed control handle    Electrical control handle makes it quick shift, position and speed changes.

·  Unique design of Z axis without rail    Up & down without steps. High precision positioning. Up & down easily in process without any impact or stop on performance. 

·  Unique water shelter design    Nice looking and easy operation. 

·  X/Y equipped with super precision linear guide    P3 grade high precision ball screw guide. Its precision is much higher than any other similar machines.

·  Dual sides wire tensioner with consistent tension    Keep the tension all the process.  Complete prevent the poor roughness problem.

·  Self greasing system   help you to save time for maintenance.

·  The taper is equipment with stronger linear guide which makes the cutting more accurate and reliable. 

·  High pressure multi screen system Designed with similar logic as slow speed WEDM. Three divisions in the water tank. Polluted water enters the first division for subside the third division. It separated the polluted water from the clean water. It saves water and environment. 

·  Water-proof guide wheel with patent design      Easier wiring and consistent precision.

·  Similar diamond guide as in slow speed WEDM       Prevent wire from vibration.

·  Wire drum is controlled with free of touch switches and AC frequency adaptor.

Posittec II Power Supply with Nanosecond Grade 400mm²/Min HF + Refine Cutting

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.
