Features
  • AC servo motors are used on machines provides “Positioning & Tension” control with high reliability.
  • DC motors control offers different wire diameters for various data.
  • High pressure air applied at wire melting system makes no burrs to the new wire.
  • Intelligent wire-cutting device, a different voltage occurs for different wire diameters.
  • Unique upper Are guide structure produces a high pressure water jet, AWT can be done in water, operator can chose Ø 0.5 mm - Ø 2.0 mm assistant flushing nozzles to thread the Ø 0.1mm - Ø 0.3mm wire.
  • Special lower wire guide to offer 2 high pressure water jet with 45° and 180°, ensure the wire will be threaded successfully.
  • Ceramic wire collecting wheel is used to bring a longer lifetime for parts.
  • PWM DC wire collecting motor is equipped to provide the linear stability.

WINDOWS CONTROL
(Launching Soon)

New generation control system
WINDOWS based design
Equipped with unique RTX clock software
User friendly, CNC control interface, for easy operation
15” touch-screen monitor and mouse,
Smoother programming for users,
Optional 4 axes on-board conversational programming system.

Intelligent OV Circuit
Specially designed intellent ignition control circuit permits ignition voltage, voltage adjustment and control by computer and is excellent for machining various work piece materials with both thick and thin sheet plates. Also a voltage stabilizing circuit maintains discharge machining at constantly high speeds and 20%, especially when working on particularly thick or think work piece.

Super Fine Loop
The super fine loop employs a high frequency, non-electrolytic machining method. The process combines high stability wire feeding tension control. All of which fabricates an extremely fine work piece surface.

Mechanical Design Features

  • Each axis uses precise ball screw and linear motion guide.
  • AC servo motor directly go through coupling to drive the ball screws.
  • The work table is manufactured from stainless design to ensure best maintenance.
  • The U, V axes located upper from the columm to offer accurate stability, it can reach precise taper machining when facing high wire tension and high water pressure.
  • High rigidity design and well thermal balance are used for precision machining.
  • Submerged work tank you don’t find more spread water, offs a complicated machining shape request and stable cutting status.
  • To put the work piece into submerged water, keeps same temperature and reach the work piece stability and non-transformed shape.
  • Simple and reliable Automatic Threading Device design, applies high precision accuracy and easy operator maintenance.
  • Specially designed Φ1.0mm high pressure water jet on the Automatic Wire Threading system, offers enhanced reliability for threading brass wire from Φ0.1mm~Φ0.3mm.
  • The Automatic Wire Threading cut design ensures a clean cut burr free sharp point to the new wire.
  • Time saving submerged Auto Wire Threading facility.
  • Heavy-duty wire spool shaft design for case of maintenance.
  • High specification 'Dynamic Wire Tension Controller’.
  • Special upper / lower wire guide set, provides high-speed automatic wire threading in water.
  • High speed submerged culling for up to 450mrn Sick work piece.
  • Specially designed 'Wire Chopper is available for some modes.
  • Large wire spool capacity (20 kits or above) system as an option, to increase wire change over up to 170 hours (20Kg brass 0.2mm).
  • Water Jet cleaning system located at rear of the tank ensures that the back seal plate and lower arm assembly are kept free from erosion debris.
  • Smooth lower arm movement fitted with anti leaking system.
  • Lower arm thermal cooling system ensures high stability.
  • Hardened Stainless work tank base, enhance rigidity and support Sealed, well-balanced, box-type design casting of the machine body ensures high thermal balance stability.
  • Each alas use high precision C1 class ball screws with manual single shot lubrication system on the X and Y axes fitted as standard.
