Machine feature

1. Rigid U, V truss design

2. Stainless steel work table with hardness HRC 50°.

3. High response AC servo motor for guaranteed accuracy

4. Extra wide machine base.

To ensure thremal balance, RIB location is designed by finite element analysis (FEA)assuring and optimized rigid structure.

Water cooled lower arm prevents thermal expansion caused by heat buildup. Therefore the accuracy will be improved.

A rugged cast iron machine structure is the foundation of precision.

Useful function

DPM - Digital Power Manager

DPM is capable of detecting digital signale signals of sparking density, providing feedback to the CNC system and calculating the sparking size.
It controls the sparking energy, wire tension force and water pressure more precisely; increases cutting speed and accuracy when cutting on irregular thickness workpieces.

Automatic Wire Threading

Continout unmanned operation day night, nonstop machining with ideal break point automatic wire threading.

Automatic Wire Threading
  • Unnecessary to pay attention to wire bread; reduction of the operation cost.
  • The multi-jobs machining would be much easier since the machining will be automatically finished without manual command.
  • G54~59 coordinate can be utilized for automatic work-piece change.
Automatic Wire Threading

Threading at the wire break point. Annealing is used to improve the straightness of the wore. The wire can be threaded at the break point during machining, with virtually 100% reliability and without the need to return to the start hole.

Submeraged Wire Threading : Wire threading is also easy execute during submerged machining, saves time to drain and refill the work tank.

Multi-hole machining function : On the rare occasion events when the machine fails to rethread during multi-hole machining, the system will skip to the next hole. The location of the skipped hole is automatically stored in memory and can be recalled later to complete the machining.

High Speed Auto Wire Threading System
Workpiece Thickness 100mm
  • Wire annealing and cutting : 10 sec
  • Threading : 10 sec
Workpiece Thickness 800mm
  • Threading under the water at break point.

Reliable Auto Wire Threading system

The EXCETEK AWT is very sophisticated design that provides continuous unmanned operation day and night. Unlike other systems it can thread at the point of the wire breakage.

A water jet function enables the machine to thread workpieces up to 500mm.
